'Egg Shell Skull' Rule

  • 30 Apr 2024

Why is it in the News?

Underlining that the state and central consumer courts incorrectly applied the ‘eggshell skull’ legal principle, the Supreme Court recently restored the compensation of Rs 5 lakhs awarded by the district consumer forum in a medical negligence case.

What is the ‘Eggshell Skull’ Rule?

  • The eggshell skull rule is a common law principle applied in civil litigation.
  • Essentially, when the offender would be liable for all injuries that might be intensified due to the peculiar conditions of the injured person that the offender might not have known.
  • Simply put, the defendant would be held responsible for injuries caused to a person when he hit him on the head, even if the victim had a particularly delicate skull or an ‘eggshell’ for a skull.
    • A person who has an eggshell skull would be more severely impacted by an act, which an otherwise “normal person” would be able to withstand.
  • The rule is applied for claiming an enhanced compensation, for damage that is more than what could have been ordinarily anticipated to be caused by the defendant.

Origin of the ‘Eggshell Skull’ Rule:

  • The 'eggshell skull' rule, also known as the 'thin skull rule,' is a legal doctrine that holds a defendant liable for all consequences resulting from their negligent or intentional actions, even if the victim's pre-existing vulnerability worsens the outcome.
  • The rule's origins can be traced back to an 1891 US case, Vosburg v. Putney, in which a boy kicked another's shin without knowing about his prior injury, leading to complications.
    • The Wisconsin Supreme Court held that the defendant was responsible for the subsequent harm, even though he did not intend to cause such severe damage.
  • A similar case in England a decade later involved a pregnant woman who experienced severe shock and gave birth to a disabled child after a horse van was negligently driven into a public house where she worked.
    • The King's Bench upheld the principle that defendants are liable for the harm caused to victims, regardless of pre-existing vulnerabilities.
  • The eggshell skull rule has been applied in various legal cases across different jurisdictions, emphasizing that defendants are accountable for the consequences of their actions, even when victims' unique vulnerabilities contribute to more significant harm.

What was the Jyoti Devi Medical Negligence Case?

  • In 2005, Jyoti Devi underwent an appendix removal surgery in Himachal Pradesh, India.
  • However, her abdominal pain persisted, leading to a four-year ordeal and multiple hospital visits.
  • Eventually, doctors discovered that a 2.5 cm needle had been left in her abdomen during the initial surgery, requiring another operation to remove it.
  • Jyoti sought compensation for medical negligence and was initially awarded Rs 5 lakhs by the district consumer forum.
  • The hospital appealed, leading to the state consumer forum reducing the compensation to Rs. 1 lakh, and the National Consumer Disputes Redressal Commission (NCDRC) increasing it to Rs. 2 lakhs.

What did the SC Rule?

  • The Supreme Court (SC) restored the original Rs 5 lakh compensation, criticizing the lower compensation amounts as "paltry" and "unjust."
  • The SC ruled that the 'eggshell skull' rule did not apply in Jyoti's case since there was no evidence of a pre-existing vulnerability or medical condition that contributed to her suffering.
  • The court cited two factors for increasing the compensation: Jyoti's prolonged pain over five years and the decade-long legal battle she endured.

Global Leaders Group on Antimicrobial Resistance

  • 30 Apr 2024

Why is it in the News?

The European Society for Clinical Microbiology and Infectious Diseases (ESCMID) and the Global Leaders Group (GLG) on AMR jointly organized a high-level event, ‘Forging partnerships between science and policy’, on April 26, 2024, in Barcelona, Spain.

About Global Leaders Group on Antimicrobial Resistance:

  • Established in November 2020, the Global Leaders Group on Antimicrobial Resistance is a collaborative effort of world leaders and experts from various sectors working together to accelerate political action against antimicrobial resistance (AMR).
  • The Group serves as an independent global advisory and advocacy entity, striving to maintain public support, political momentum, and visibility of AMR on the global health and development agenda.
  • Background: The Group emerged from a recommendation by the Interagency Coordination Group on Antimicrobial Resistance, aiming to strengthen global leadership and political action against AMR.
  • The first meeting of the Group was held in January 2021.

Secretariat Support:

  • The Quadripartite Joint Secretariat (QJS) on Antimicrobial Resistance, a joint effort by the Food and Agriculture Organization of the United Nations (FAO), the United Nations Environment Programme (UNEP), the World Health Organization (WHO), and the World Organisation for Animal Health (WOAH), provides secretariat support for the Group.
  • Through its collaborative and multisectoral approach, the Global Leaders Group on Antimicrobial Resistance is committed to addressing the growing threat of AMR and promoting responsible and sustainable access to antimicrobials.

What is antimicrobial resistance (AMR)?

  • Antimicrobial resistance (AMR) refers to the ability of microorganisms, such as bacteria, viruses, fungi, and parasites, to develop resistance to the effects of antimicrobial drugs, such as antibiotics, antivirals, antifungals, and antiparasitics.
  • As a result, the medications become less effective or even ineffective at treating infections caused by these resistant microorganisms.
  • AMR occurs when microorganisms undergo genetic changes that enable them to survive exposure to antimicrobial drugs.
  • These changes can be shared between different microorganisms, leading to the spread of resistance genes.
  • Over time, the increased use and misuse of antimicrobial drugs have accelerated the development of AMR.

Common factors contributing to AMR include:

    • Overprescription of antimicrobials
    • Non-adherence to prescribed treatment regimens
    • Misuse of antimicrobials in agriculture and livestock farming
    • Poor sanitation and hygiene practices
    • Lack of access to clean water
  • The rise of AMR poses a significant threat to public health, as it makes the treatment of common infections more difficult and increases the risk of complications.
  • Additionally, AMR has implications for global health security, as resistant infections can spread rapidly across regions and become a major public health challenge.

Why is it in the News?

Recently, scientists have uncovered a massive sinkhole off the coast of the Yucatan Peninsula in Mexico.

What is Taam Ja' Blue Hole?

  • Taam Ja' Blue Hole is the world's deepest known underwater sinkhole, recently discovered in Chetumal Bay off Mexico's Yucatan Peninsula.
  • The blue hole extends approximately 420 meters (1,380 feet) below sea level, making it significantly deeper than the previous record holder, the Dragon Hole in the South China Sea.
  • The nearly circular sinkhole covers an area of around 13,660 square meters and features steep sides covered in biofilms, sediments, limestone, and gypsum ledges.
  • Named "Taam Ja'," meaning "deep water" in the Mayan language, the blue hole was initially discovered by a local diver in 2003 but only recently gained scientific attention.
  • Further research is ongoing to explore the unique marine life and geological features within this remarkable underwater cavern.

What is a Blue Hole?

  • A blue hole is a large, underwater sinkhole or cavern with a submerged opening that appears dark blue from above due to the depth and clarity of the water.
    • The name "blue hole" originates from the striking contrast between the dark blue, deep water within the hole and the lighter blue shallower water surrounding it.
  • These unique geological formations are typically formed through a combination of erosion and dissolution of limestone bedrock, resulting in circular or ovular depressions in the seafloor.
    • Over time, blue holes can develop distinct ecosystems hosting a variety of marine life, including unique and rare species that have adapted to the specific conditions within these habitats.
  • Blue holes can be found in various parts of the world, both in oceanic and inland settings.
    • Some famous examples include the Great Blue Hole in Belize, the Dean's Blue Hole in the Bahamas, and the Taam Ja' Blue Hole in Mexico.

Thrombosis with Thrombocytopenia Syndrome (TTS)

  • 30 Apr 2024

Why is it in the News?

Global pharmaceutical giant AstraZeneca has said that its AZD1222 vaccine against Covid-19, which was made under license in India as Covishield, could cause low platelet counts and formation of blood clots in “very rare” cases.

What is Thrombosis with Thrombocytopenia Syndrome (TTS)?

  • Thrombosis with Thrombocytopenia Syndrome (TTS) is characterised by thrombosis formation (blood clots) combined with thrombocytopenia (low platelet count) with symptoms typically presenting in the 4-42 days after vaccination.
    • Platelets are small cells that help blood to clot, so having too few of them can be dangerous.
  • It often involves unusual blood clot locations, such as in the brain (cerebral venous sinus thrombosis) or abdomen.
    • The condition was observed in people who received adenoviral vector COVID-19 vaccines, such as Vaxzevria, Covishield (AstraZeneca), and the Johnson & Johnson/Janssen COVID-19 vaccine.
  • TTS seems to occur because the body's immune system reacts to the vaccine by making antibodies that attack a protein involved in blood clotting.
  • According to the Centers for Disease Control (CDC), TTS is classified into 2 tiers based on the location of thrombosis and severity of symptoms.

Tier 1:

  • Rare blood clots, like in the brain or gut, sometimes alongside more typical ones in the legs or lungs.
  • Low platelet count (below 150,000 per microliter).
  • Positive anti-PF4 ELISA tests can help confirm diagnosis but aren't always needed.
  • Tier 1 cases are usually more severe and riskier.
  • This is more common in younger people.

Tier 2:

  • Common blood clots, like in the legs or lungs.
  • Low platelet count (below 150,000 per microliter).
  • A positive anti-PF4 ELISA test is necessary for diagnosis.

Symptoms of TTS:

  • Symptoms of TTS can include severe headaches, stomach pain, swelling in the legs, trouble breathing, and problems with thinking or seizures.

Great Rift Valley

Why is it in the News?

A dam burst near a village in the Rift Valley region of southern Kenya in the early hours of April 29, 2024. Some 45 people have been killed according to the police chief of Nakuru County, where the incident took place.

About the Great Rift Valley:

  • The Great Rift Valley, part of the larger East African Rift System (EARS), is a significant geological feature extending across East Africa, from Jordan in southwestern Asia to central Mozambique's coast along the Indian Ocean.
  • Running through numerous countries including Eritrea, Djibouti, Ethiopia, Kenya, Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of Congo, Malawi, Zambia, and Mozambique, the valley is one of Earth's most expansive rifts.

Formation:

  • Resulting from tectonic plate movements about 40 million years ago, the Great Rift Valley's formation is linked to the East African Rift's emergence.
  • Geologically active, the region experiences frequent earthquakes, volcanoes, hot springs, and geysers.

Notable Features:

  • A series of approximately 30 lakes dot the Great Rift Valley, including Lake Tanganyika (the world's second-deepest lake) and Lake Victoria (the second-largest freshwater lake by surface area).
  • Many of Africa's highest mountains, such as Mount Kilimanjaro, Mount Kenya, and Mount Margherita, form part of ranges fronting the valley.

What is a Rift Valley?

  • A rift valley is a lowland region that forms where the Earth's tectonic plates move apart or rift.
    • Rift valleys are a result of the tectonic processes that shape the Earth's surface, specifically in regions where tectonic plates are diverging or pulling away from each other.
  • Rift valleys are characterized by a long, narrow depression, often with steep sides, running along the length of the rift.
    • The depression is caused by the sinking of the ground between the two diverging plates as they pull away from each other.
    • The thinning of the Earth's crust leads to subsidence and the formation of a valley.
  • Rift valleys can be found on land as well as on the ocean floor.

Some notable examples of rift valleys include:

  • The Great Rift Valley in East Africa is part of the larger East African Rift System.
  • The Red Sea Rift separates the African and Arabian tectonic plates.
  • The Rhine Valley in Europe was formed by the divergence of the European and African plates.
  • Rift valleys are geologically active areas often associated with volcanic activity, earthquakes, and the formation of hot springs, geysers, and other hydrothermal features.

Green Taxonomy

  • 29 Apr 2024

Why is it in the News?

The RBI and the Finance Ministry could draw inspiration from the ASEAN region's evolving green taxonomy, continually updated with sectoral insights, to enhance sustainability efforts.

What is Green Taxonomy?

  • Green taxonomy is a pivotal framework designed to delineate environmentally sustainable investments, providing clarity on which economic activities and assets qualify as "green" or environmentally sound.
  • It plays a crucial role in advancing global sustainability objectives, particularly in the context of combating climate change and transitioning towards a low-carbon economy.

What is Green Taxonomy?

  • At its core, green taxonomy serves as a comprehensive tool for classifying economic activities and assets based on their environmental sustainability.
  • It is crafted by governments, regulators, and stakeholders with a commitment to achieving net-zero carbon emissions and fostering sustainable development.

Significance of Green Taxonomy:

  • The significance of green taxonomy lies in its multifaceted role:
  • Preventing Greenwashing: By establishing clear criteria and standards, green taxonomy helps prevent greenwashing, a deceptive practice wherein investments are portrayed as environmentally friendly when they may not be.
  • Informing Investment Decisions: Investors are empowered to make informed decisions by utilizing the taxonomy as a guide. It offers transparency and guidance, enabling investors to align their investment strategies with environmental objectives.
  • Directing Investments Towards Sustainability: The taxonomy serves as a tool for channeling investments towards sustainable economic activities and assets. By identifying and classifying green investments, it encourages the allocation of capital to projects that contribute positively to environmental goals.

Common Features of Green Taxonomies:

  • Green taxonomies typically include objectives related to climate mitigation and adaptation, with some also incorporating additional environmental goals such as biodiversity conservation.
  • To qualify as green, an activity must substantially contribute to at least one of these environmental objectives.
  • Furthermore, green taxonomies often integrate "do no significant harm" criteria, ensuring that activities considered green do not compromise other environmental objectives.
  • Additionally, they emphasize compliance with social safeguards, including human rights considerations.

Nuanced Approaches in Green Taxonomies:

  • Some taxonomies adopt a nuanced approach, such as the "traffic light" system utilized by the Indonesian and proposed Singaporean taxonomies.
  • Under this approach, economic activities are categorized into different tiers (green, amber, or red) based on their environmental sustainability.
  • This system offers a more nuanced understanding of the environmental impact of various activities, allowing for tailored assessments and decision-making.

What Is Greenwashing?

  • Greenwashing is the process of conveying a false impression or misleading information about how a company’s products are environmentally sound.
  • Greenwashing involves making an unsubstantiated claim to deceive consumers into believing that a company’s products are environmentally friendly or have a greater positive environmental impact than they actually do.
  • In addition, greenwashing may occur when a company attempts to emphasize sustainable aspects of a product to overshadow the company’s involvement in environmentally damaging practices.
  • Performed through the use of environmental imagery, misleading labels, and hiding tradeoffs, greenwashing is a play on the term “whitewashing,” which means using false information to intentionally hide wrongdoing, error, or an unpleasant situation in an attempt to make it seem less bad than it is.

Expanding Glacial Lakes in the Indian Himalayas: ISRO

  • 27 Apr 2024

Why is it in the News?

Experts express concern over the ISRO analysis findings, indicating that the expansion of glacial lakes due to warming could result in cascading impacts in lower regions.

Highlights of the ISRO Report:

  • The ISRO report said 601 glacial lakes, or 89 percent, have expanded more than twice, and 10 lakes have grown between 15 times and double their size. Sixty-five lakes have expanded 1.5 times.
  • Of the 2,431 glacial lakes larger than 10 hectares, 676 have significantly expanded, and at least 130 of these lakes are in India 65 (Indus River basin), 7 (Ganga River basin), and 58 (Brahmaputra River basin).
  • Elevation-based analysis shows 314 lakes are located in the 4,000 to 5,000 meters range, and 296 lakes are above 5,000 meters elevation.

What are Glacial Lakes?

  • Glacial lakes emerge in hollows or basins shaped by glaciers' erosive force and are prevalent in areas where glaciers once existed or persist.
  • They vary widely in size and shape, from tiny pools to expansive bodies of water.
  • ISRO classifies them into four main types: moraine-dammed, ice-dammed, erosion-based, and 'others'.
  • While vital as freshwater sources for rivers, glacial lakes also pose risks, particularly Glacial Lake Outburst Floods (GLOFs).
    • GLOFs occur when these lakes discharge large volumes of meltwater, often due to natural dam failures, causing sudden and severe downstream flooding.

Formation Processes:

  • Glacial Erosion: Glaciers, moving slowly, sculpt the landscape by eroding bedrock through abrasion and plucking, creating valleys and basins.
  • Moraine Deposition: As glaciers move, they transport sediment, depositing it at their edges as moraines, which can act as natural dams, forming lake basins.
  • Ice Melting: Rising temperatures or glacier retreat causes ice to melt, filling depressions created by erosion with water, and forming glacial lakes.
  • Terminal Moraine Formation: Glaciers may leave behind ridges of sediment at their terminus, creating natural dams that trap water, forming terminal moraine lakes.

Utilization of Remote Sensing for Glacial Lake Monitoring:

  • Monitoring glacial lakes in the Himalayan region presents challenges due to rugged terrain, making satellite remote-sensing technology indispensable.
  • By analyzing satellite data, changes in glacial lakes can be tracked over time, offering insights into their evolving dynamics.
  • This data is vital for understanding their environmental impact and devising strategies to manage risks such as glacial lake outburst floods (GLOFs) and adapt to climate change in glacier-influenced regions.

Mitigating Risks Associated with Glacial Lakes:

  • Research suggests that reducing glacial lake levels by 10 to 30 meters can significantly alleviate downstream impacts, albeit not eliminate GLOF risks.
  • One effective method involves siphoning off lake water using extended High-Density Polyethylene (HDPE) pipes.
  • In 2016, the Sikkim State Disaster Management Authority successfully employed this technique to lower water levels in South Lhonak Lake, showcasing its practicality and efficacy in risk reduction efforts.

Symbol Loading Units (SLUs)

  • 27 Apr 2024

Why is it in the News?

Recently, the Supreme Court rejected the plea for full verification of VVPAT slips against EVM counts and directed the ECI to seal the Symbol Loading Unit (SLU) for 45 days post-election results announcement.

What is a Symbol Loading Unit (SLU) and How Does it Work?

  • Symbol Loading Units (SLUs) were introduced around the same time as VVPATs, a little over a decade ago.
  • VVPATs help voters verify their votes, they see a slip with a printed image of the party symbol they voted for.
  • But for the VVPAT to print a symbol correctly, information pertaining to the list of candidates and their symbols must be loaded onto the VVPAT machine in the correct order.
  • This is where the Symbol Loading Unit, or SLU, comes in.
  • The introduction of VVPATs necessitated the use of SLUs.
  • The SLU is used to load the symbols of the candidates onto the VVPAT.
  • It is a matchbox-sized device that is first connected to a laptop or personal computer, from where a symbol-loading application is used to load a bitmap file containing the candidates’ names, serial numbers, and symbols.
  • The SLU is then connected to the VVPAT to transfer that file onto the paper audit machine.
  • This is done under the supervision of a district election officer.

At Which Point in the Election Process Are SLUs Used?

  • The SLUs come into the picture only a few days before polling in a particular seat, when the EVMs are being commissioned and the list/ order of contesting candidates is decided and set on the ballot unit and the VVPAT.
  • Candidate-setting can happen at any time from five to two days before voting at a seat.
  • Once the SLU is used to load symbols onto the VVPAT, the EVM is ready for use.
  • After this, the SLU is of no relevance to the actual voting process.

What Happens to an SLU After Symbols Are Loaded?

  • Typically, a small number of SLUs are enough to load symbols onto all VVPATs for a seat.
  • According to EC officials, it takes an SLU two to three minutes to load each VVPAT.
  • Once the symbol-loading is complete, the SLUs are handed over to the concerned district election officer for safekeeping.
  • They remain in the officer’s custody until the day after voting. Afterward, the SLUs are released to the engineers of the two EVM manufacturers, Bharat Electronics Ltd (BEL) or Electronics Corporation of India Ltd (ECIL), so they can be used to load symbols onto VVPATs for other seats in subsequent phases.
  • Thus, in a multi-phase election like the ongoing one for the 18th Lok Sabha, an SLU is typically reused after one phase of polling to load symbols onto VVPATs meant for other seats in subsequent phases.

Bambi Bucket

  • 27 Apr 2024

Why is it in the News?

Recently, an Indian Air Force MI 17 V5 helicopter, equipped with a Bambi Bucket, was deployed to combat the forest fires in Nainital district, Uttarakhand.

What is a Bambi Bucket?

  • Bambi Bucket is a specialised aerial firefighting tool that has been in use since the 1980s.
  • It is essentially a lightweight collapsible container that releases water from underneath a helicopter to targeted areas.
  • The water is released by using a pilot-controlled valve.
  • One of its key features is that it can be quickly and easily filled.
  • The bucket can be filled from various sources, including a lake, river, pond, and swimming pool, which allows firefighters to swiftly refill it and return to the target area.
  • Bambi Bucket is available in a variety of sizes and models, with capacities ranging from 270 liters to more than 9,840 liters.

How was the Bambi Bucket Invented?

  • The Bambi Bucket was invented by Don Arney, a Canadian business, in 1982.
  • Arney came up with the idea after he realised that the aerial firefighting water buckets in use at the time were not efficient and had a high failure rate.
    • These water buckets were generally made of “solid fiberglass, plastic, or canvas with metal frames” and were “too rigid to fit inside the aircraft” and had to be “trucked to fire sites or flown in on the hook of a helicopter thereby slowing the aircraft down.
    • Another issue was that the water dropped from these containers used to get dispersed into a spray thereby reducing impact.
  • Bambi Bucket does not have these limitations.
    • One, it can be stored within the helicopter until development.
    • Two, it discharges a solid column of water, “resulting in a more accurate and effective water dump, less evaporation on the descent, and greater impact force.
  • It was an instant success and began to be widely used for firefighting.
  • Today, Bambi Bucket is used in more than 115 countries around the world by more than 1,000 helicopter operators.

Carnation Revolution

Why is it in the News?

Recently, Portugal commemorated its 50th anniversary of Portugal's Carnation Revolution – the peaceful uprising that toppled a dictatorship and ended a decade of colonial war.

About the Carnation Revolution:

  • The Carnation Revolution, also known as the 25th of April, was a pivotal event in Portugal's history that marked the transition from an authoritarian regime to a democratic government.
    • On April 25, 1974, a group of military officers orchestrated a nearly bloodless military coup, overthrowing the Estado Novo dictatorship that had ruled Portugal for over four decades.
  • The revolution aimed to accelerate decolonization, end ongoing wars through negotiations, and improve socio-economic conditions within Portugal.
    • This event not only transformed Portugal's political landscape but also had significant implications for the nation's African colonies.
  • Several factors contributed to the success of the Carnation Revolution, including widespread discontent with the authoritarian regime, a costly and unpopular colonial war, and the growing desire for democracy and improved living conditions.
    • The coup leaders, known as the Armed Forces Movement (MFA), garnered support from various factions, including the Communist Party, socialists, and moderate democrats.
  • The Carnation Revolution was named after a Lisbon flower seller who offered red carnations to soldiers, which were then placed in the barrels of their rifles.
    • This iconic gesture symbolized the peaceful nature of the coup and solidified the carnation as a symbol of Portugal's democratic movement.
  • The 50th anniversary of the Carnation Revolution celebrated on April 25, 2024, signifies the enduring impact of this historic event on Portugal's political trajectory and its relationship with its former colonies.

Bathymetry

  • 26 Apr 2024

Why is it in the News?

Scientists from the Indian National Centre for Ocean Information Services (INCOIS) recently conducted a study of the bathymetry, or ocean floor, in the Indian Ocean.

What is Bathymetry?

  • Bathymetry is a technique dedicated to mapping the depths of water bodies, that is, it is the measurement and representation of the topography of the bottom of rivers, seas, and oceans.
  • In addition to measuring depth, this study also includes identifying underwater relief and creating three-dimensional maps of the sea floor.
  • The word “bathymetry” comes from the Greek "bathýs", meaning deep, and "metron", meaning measure.
  • Bathymetry allows for obtaining information about the physical characteristics of the sea floor, such as seamounts, mountain ranges, valleys, abyssal plains, and underwater canyons.

How is Bathymetry Performed?

  • To carry out bathymetry, specific equipment is used, such as multibeam sonar (MultiBeam Echosounder), IMU (Inertial Measurement Unit), and high-precision positioning systems (via satellite with RTK correction).
  • Multibeam sonar emits sound pulses toward the sea floor and measures the time it takes for the sound to return to the sensor after being reflected by submerged surfaces.
  • Based on this sound return time and knowledge of the exact position of the vessel and its attitude (roll, pitch, yaw), it is possible to calculate the depth at a given point.
  • The bathymetry service generates charts, blueprints, and digital models (2D and 3D) of the sea floor.
  • LiDAR sensors, on the other hand, are used to detect data through beams of light above the waterline, mapping slopes, rockfills, and channel walls.
  • The fusion of bathymetry data with Lidar data allows the three-dimensional construction of the environment in very high resolution.
  • Allowing the client to plan or verify works and/or assets in the region of interest.

 About Indian National Centre for Ocean Information Services (INCOIS):

  • Established in 1999, the Indian National Centre for Ocean Information Services (INCOIS) under the Ministry of Earth Science, Govt of India.
  • It is mandated to provide ocean information and advisory services to a broad spectrum of users through sustained ocean observations and constant improvements through systematic and focused research.
  • The activities include data services, consultancy, and capacity development.
  • HQ: Hyderabad
  • INCOIS is a permanent member of the Indian delegation to the IOC of UNESCO and a founding member of the Indian Ocean Global Ocean Observing System (IOGOOS) and the Partnership for Observing the Oceans (POGO).

Inflammatory bowel disease (IBD)

  • 26 Apr 2024

Why is it in the News?

The rising incidence of Inflammatory Bowel Disease (IBD) across the globe has become a concern for doctors, while early diagnosis is lacking, diagnosis in itself is challenging considering that other conditions could mimic IBD.

What is IBD?

  • Inflammatory bowel disease (IBD) is a recurring and long-term (chronic) condition that affects the digestive tract.
  • IBD causes inflammation of the stomach, small intestine, and colon.
  • IBD is a progressive disease that can become worse over time and cause other damage if not properly diagnosed and treated.
  • There are two types of IBD: Crohn’s disease and ulcerative colitis.
    • Crohn’s disease: leads to inflammation anywhere in the gastrointestinal tract, however, it commonly affects the end of the small intestine (the ileum) and the beginning of the large intestine (the right colon).
      • Crohn’s disease can also affect the entire thickness or alternating areas of the bowel wall.
    • Ulcerative colitis: causes inflammation in the large intestine or colon.
      • This form of IBD inflames the innermost lining of the colon and creates tiny open sores (ulcers).

What causes IBD?

  • The exact cause of IBD is unknown, but IBD is the result of a weakened immune system. Possible causes are:
  • The immune system responds incorrectly to environmental triggers, such as a virus or bacteria, which causes inflammation of the gastrointestinal tract.
  • There also appears to be a genetic component.
    • Someone with a family history of IBD is more likely to develop this inappropriate immune response.

Symptoms of IBD:

  • Although Crohn's disease and ulcerative colitis are different conditions, IBD conditions have similar symptoms, such as:
    • Abdominal pain
    • Diarrhea
    • Rectal bleeding
    • Vomiting
    • Weight loss

How Is Inflammatory Bowel Disease (IBD) Treated?

  • While there is no curative treatment for IBD, it is managed through medication, dietary changes, and occasionally surgery.
  • The treatment aims to alleviate symptoms, mitigate complications, prevent future flare-ups, and potentially promote the healing of inflamed intestines.

Nephrotic Syndrome

  • 26 Apr 2024

Why is it in the News?

On the heels of recent news reports on how keratin-based hair-straightening products containing glycolic acid derivatives led to severe kidney injury in women, researchers from Kerala have reported a series of cases wherein, the use of fairness creams has been linked to nephrotic syndrome.

What is Nephrotic Syndrome?

  • Nephrotic syndrome causes scarring or damage to the filtering part of the kidneys (glomeruli).
  • This causes too much protein to be lost from the blood into the urine.

People with nephrotic syndrome often have:

    • Low levels of protein in the blood (hypoalbuminemia)
    • Very high levels of protein in the urine (proteinuria)
    • Swelling (edema), especially around the eyes, feet, and hands
    • High cholesterol

What causes nephrotic syndrome?

  • Nephrotic syndrome results from damage to the kidneys' glomeruli.
    • These are the tiny blood vessels that filter waste and excess water from the blood and send them to the bladder as urine.
    • The glomeruli keep protein in the body. When they are damaged, protein leaks into the urine.
    • Healthy kidneys allow less than 1 gram of protein to spill into the urine in a day.
    • In nephrotic syndrome, the glomeruli let 3 grams or more of protein leak into the urine during 24 hours.
  • Nephrotic syndrome may happen with other health problems, such as kidney disease caused by diabetes and immune disorders.
  • It can also develop after damage from viral infections.
  • The cause of nephrotic syndrome is not always known.

What are the symptoms of nephrotic syndrome?

  • The symptoms of nephrotic syndrome include:
    • Swelling or edema, typically in the ankles, feet, or legs
    • Fatigue
    • Loss of appetite
    • Weight gain
    • Foamy urine

Treatment:

  • The treatment of nephrotic syndrome varies depending on its cause.
  • However, it typically includes medications to treat the underlying cause, as well as changes in diet.
  • Dietary changes that might help in treating nephrotic syndrome include Source:
    • limiting sodium
    • eating less protein
    • reducing the intake of saturated fat and cholesterol

Complications of nephrotic syndrome:

  • Serious complications of nephrotic syndrome include kidney failure or end-stage renal disease (ESRD).
  • Dialysis may be needed if kidney failure develops which can happen in extreme cases.

Army Tactical Missile Systems (ATACMS)

  • 26 Apr 2024

Why is it in the News?

The United States has confirmed providing long-range Army Tactical Missile Systems (ATACMS) to Ukraine to aid its war effort against Russia.

What is the ATACMS System?

  • The Army Tactical Missile Systems (ATACMS) is one of the most potent missile systems built by US-based arms manufacturer Lockheed Martin.
  • This is a surface-to-surface artillery weapon system.
  • Its biggest strengths are the long-range of attack, the ability to fire cluster munitions, and the weapon system’s mobility.
  • Range: There is a mid-range version of the ATACMS, called Block 1, and a long-range version, Block 1A.
    • ATACMS Block 1 has a range of 165 kilometres. Ukraine was provided these systems last year and used them to attack targets in October.
    • ATACMS Block 1A, on the other hand, has a maximum range of 300 km. However, this depends on the kind of munition the missile carries.
  • With such a range, the long-range ATACMS Block 1A is capable of striking targets well beyond the range of existing Army cannons, rockets, and other missiles.
  • Mobility: ATACMS missiles are fired from the High Mobility Artillery Rocket System (HIMARS) and M270 Multiple Launch Rocket System (MLRS) platforms. Both of these launching systems are highly mobile automatic systems.

Why Ukraine can’t use ATACMS to Target Russian Territories?

  • Despite territories deep inside Russia now being within the range of the ATACMS, Ukraine cannot use it to hit targets in these locations.
  • Ukraine has committed to only use the weapons inside Ukraine, not in Russia.
  • The US administration has made it clear that the weapons cannot be used to hit targets inside Russia.
  • The Biden administration is concerned that if Ukraine strikes deep into Russian territory, it will anger Moscow and escalate the conflict.

Microsoft Phi-3-Mini

  • 25 Apr 2024

Why is it in the News?

A few days after Meta unveiled its Llama 3 Large Language Model (LLM), Microsoft recently unveiled the latest version of its ‘lightweight’ AI model – the Phi-3-Mini.

What is Phi-3-Mini?

  • Phi-3 refers to a series of language models developed by Microsoft, with Phi-3-mini being a notable addition.
  • Phi-3-mini is a 3.8 billion parameter language model trained on 3.3 trillion tokens, designed to be as powerful as larger models while being small enough to be deployed on a phone.
  • Despite its compact size, Phi-3-mini boasts impressive performance, rivaling that of larger models such as ChatGPT-3.5.
  • Furthermore, Phi-3-mini can be quantized to 4 bits, occupying approximately 1.8GB of memory, making it suitable for deployment on mobile devices.

    • It cannot store extensive “factual knowledge,” leading to lower performance on tasks such as TriviaQA.
    • Nevertheless, efforts to resolve this weakness are underway, including augmentation with a search engine and exploring multilingual capabilities for Small Language Models.
  • Safety: Phi-3-mini was developed with a strong emphasis on safety and responsible AI principles, in alignment with Microsoft’s guidelines.
    • The approach to ensuring safety involved various measures such as safety alignment in post-training, red-teaming, and automated testing.
    • It also involved evaluations across multiple categories of responsible AI (RAI) harm.

How is Phi-3-Mini Different From LLMs?

  • Phi-3-mini is the Small Language Model (SLM). Simply, SLMs are more streamlined versions of large language models.
  • When compared to Large Language Model (LLM), smaller AI models are also cost-effective to develop and operate, and they perform better on smaller devices like laptops and smartphones.
  • SLMs are great for “resource-constrained environments including on-device and offline inference scenarios.
  • Such models are good for scenarios where fast response times are critical, say for chatbots or virtual assistants.
  • Moreover, they are ideal for cost-constrained use cases, particularly with simpler tasks.
  • While LLMs are trained on massive general data, SLMs stand out with their specialisation.
  • Through fine-tuning, SLMs can be customised for specific tasks and achieve accuracy and efficiency in doing them.
  • Most SLMs undergo targeted training, demanding considerably less computing power and energy compared to LLMs.
  • SLMs also differ when it comes to inference speed and latency.
  • Their compact size allows for quicker processing and their cost makes them appealing to smaller organisations and research groups.

Ross Ice Shelf

  • 25 Apr 2024

Why is it in the News?

New research has found a "missing piece of the puzzle" of West Antarctic Ice Sheet melt, revealing that the collapse of the ice sheet in the Ross Sea region can be prevented—if we keep to a low-emissions pathway.

About Ross Ice Shelf:

  • The Ross Ice Shelf is a floating mass of land-ice, with a front between 15 and 50 meters high. ?
  • It is the largest ice shelf in Antarctica.
  • Situated in the Ross Sea, it extends off the coast into the ocean, covering an impressive 487,000 square kilometers, roughly the size of France.
  • Despite its vast surface area, only 10% of the ice shelf is visible above the water, mostly concealed beneath hundreds of meters of ice.
  • The thickness of the Ross Ice Shelf varies significantly, ranging from about 100 meters to several hundred meters at its thickest points near the areas where the shelf connects to the Antarctic continent.
  • The formation of the Ross Ice Shelf is the result of snow accumulation and compaction over time, which ultimately transforms into ice.
  • It is continuously fed by glaciers draining from both the East and West Antarctic Ice Sheets, creating a balance as new ice is added while existing ice is removed through melting at the base and calving at the front.
  • This massive ice shelf plays a critical role in stabilizing the Antarctic ice sheet.

About the Ross Sea:

  • Location and Size: The Ross Sea is a vast, remote bay located just 320 km from the South Pole, positioned south and slightly east of New Zealand.
  • It covers an area of approximately 370,000 square miles (960,000 square km), making it the largest polar marine ecosystem in the world.
  • The sea's dynamics are significantly shaped by the coastal East-Wind Drift, which establishes a vast clockwise gyre, complemented by deepwater upwelling phenomena.
  • Notably, it holds the distinction of being Antarctica's first protected area, serving as a habitat for a plethora of penguin species and numerous whale species.
  • Depth: Despite its vast size, the Ross Sea is relatively shallow, with an average depth of approximately 530 meters.
  • Historical Exploration: The sea is named after British explorer Sir James Clark Ross, who first visited the area in 1841 during his expedition to Antarctica.
  • The Ross Sea's importance to both the scientific community and global conservation efforts cannot be overstated, as it provides valuable insights into the effects of climate change on polar ecosystems.

Psychoanalysis

  • 24 Apr 2024

Why is it in the News?

Sudhir Kakar, a pioneering Indian psychoanalyst, author, and cultural critic, passed away on Monday at the age of 85.

What is Psychoanalysis?

  • Psychoanalysis is a set of psychological theories and therapeutic methods that focus on the unconscious mind, as well as the role of repressed emotions and desires in shaping behavior and mental health.
  • Developed by Sigmund Freud in the late 19th and early 20th centuries, psychoanalysis is based on the idea that many of our thoughts, feelings, and actions are influenced by unconscious motives and conflicts, often rooted in childhood experiences.
  • Psychoanalysis has three core components:
    • A method of investigation of the mind and the way one thinks.
    • A systematized set of theories about human behavior.
    • A method of treatment for psychological and emotional issues.
  • Key concepts in psychoanalysis include the id, ego, and superego (the structural model of the psyche), the Oedipus complex, defense mechanisms (such as repression, denial, and projection), and dream interpretation.
  • During psychoanalysis therapy, a patient works closely with a therapist to explore and understand unconscious thoughts and feelings, often by discussing dreams, memories, and other experiences.
  • The goal is to bring repressed emotions to the surface and address any underlying conflicts in order to alleviate mental distress and improve overall well-being.

Zero Shadow Day

  • 22 Apr 2024

Why is it in the News?

A group of students was provided a first-hand experience of the Zero Shadow Day (ZSD) phenomenon at an event organized by the Pondicherry Science Forum (PSF).

What is Zero Shadow Day?

  • Zero Shadow Day occurs twice every year in locations between the Tropics of Cancer and Capricorn, where the Sun is positioned directly overhead at noon.
  • The shadow typically appears elongated on the ground while being observed under normal circumstances.
  • However, when the shadow perfectly aligns under the object, during a short period of time, it remains absent on the ground.
  • This happens when the sun reaches the zenith, its highest point of revolution.
  • The dates of the occurrence may vary depending on the specific location and its latitude.

Why does Zero Shadow Day occur? 

  • Zero Shadow Day is caused due to Earth's axial tilt of approximately 23.5 degrees and its orbit around the Sun.
  • The Sun is never overhead causing it to maintain a slightly lower altitude either north or south.
  • The tilting position is also responsible for different seasons on Earth.
  • As the Earth orbits the sun, the angle at which the sun's rays hit the Earth's surface changes, causing shadows to be cast in different directions.
  • In regions falling between the Tropic of Cancer (about 23.5 degrees north of the equator) and the Tropic of Capricorn (about 23.5 degrees south of the equator), there are instances when the Sun is exactly overhead.
  • Since the sun's rays come down almost vertically, there is no or little shadow on vertical objects.

Vasuki Indicus

  • 20 Apr 2024

Why is it in the News?

Fossils recovered from Kutch in Gujarat may have belonged to the spine of one of the largest snakes to have ever lived, according to new research from the Indian Institute of Technology Roorkee.

Highlights of the Vasuki Indicus Discovery:

  • A nearly 50-foot-long snake species, one of the longest and largest in recorded history,  once existed in the Indian subcontinent.
  • The reptile, Vasuki indicus, lived in India nearly 47 million years ago, fossil remains found from Gujarat’s Panandhro Lignite Mine in Kutch suggest.
  • This giant snake, named Vasuki indicus, is estimated to have reached 15 meters in length, exceeding even a T-Rex.
  • Scientists found 27 vertebrae, some even in their original position within the spine. They believe Vasuki resembled a large python and lacked venom.
  • The species was given the specific name of Vasuki indicus in acknowledgment of the country of its origin, India.
    • Vasuki is revered as the king of the snakes in Hindu mythology and is worshiped on special days like Nag Panchami.

About Vasuki Indicus:

  • Vasuki indicus belongs to the Madtsoiidae family, and thrived during a “warm geological interval".
    • Researchers suggest that the warm tropical temperatures of Gondwanaland, averaging around 28°C, may have contributed to the substantial size and growth of this giant reptile.
    • There is a recognized correlation suggesting that higher ambient temperatures can enable larger growth in animals.
  • Madtsoiids were also found in Europe and Africa, besides Asia.
  • Vasuki indicus represents a large lineage of Madtsoiidae that originated in the Indian subcontinent and then spread to southern Eurasia, before reaching North Africa around 50 million years ago, that’s nearly 15 million years after the dinosaurs went extinct.
  • Madtsoiidae, an extinct lineage of terrestrial snakes, thrived on the Indian subcontinent over a span of approximately 100 million years, from the Late Cretaceous to the Late Pleistocene, dating from roughly 98 million to 11,000 years ago.
  • During the Late Cretaceous period, the supercontinent Pangea had fragmented into two major landmasses:
    • Laurasia, encompassing North America, Europe, and Northern Asia to the north; and
    • Gondwanaland to the south, which included present-day Africa, Antarctica, South America, Australia, and the Indian subcontinent.
  • The fossils of Vasuki indicus extracted from the early Lutetian grey shale layers of the Naredi Formation at the Kutch mine include an “excellently preserved, partial vertebral column”.
  • The discovery sheds light on the biogeographic patterns of dispersion and diversification within the Madtsoiidae, particularly across the Gondwanan continents.
  • The presence of this giant snake in the Eocene of India indicates a complex history of faunal exchanges between the Indian subcontinent and other landmasses prior to complete integration into the Eurasian plate.

Coral Bleaching

  • 19 Apr 2024

Why is it in the News?

The fourth global mass coral bleaching event has been triggered by extraordinary ocean temperatures, the US National Oceanic and Atmospheric Administration (NOAA) said recently.

What are Corals and Coral Reefs?

  • Corals are essentially animals, which are sessile, meaning they permanently attach themselves to the ocean floor.
  • They use their tiny tentacle-like hands to catch food from the water and sweep it into their mouth.
  • Each individual coral animal is known as a polyp and it lives in groups of hundreds to thousands of genetically identical polyps that form a ‘colony’.
  • Corals are largely classified as either hard coral or soft coral.
  • It is the hard corals that are the architects of coral reefs — complex three-dimensional structures built up over thousands of years.
  • Unlike soft corals, hard corals have stony skeletons made out of limestone that are produced by coral polyps.
  • When polyps die, their skeletons are left behind and used as foundations for new polyps.
  • Coral reefs, also referred to as “rainforests of the sea”, have existed on the Earth for nearly 450 million years.
    • Australia’s Great Barrier Reef is the largest in the world, stretching across 2,028 kilometers.

What is the Significance of Corals?

  • Coral reefs have a crucial role in marine ecosystems.
  • Thousands of marine species can be found living on one reef.
    • For instance, “the Great Barrier Reef contains over 400 coral species, 1,500 fish species, 4,000 mollusc species and six of the world’s seven sea turtle species”.
  • Research has shown that there could be millions of undiscovered species of organisms living in and around reefs.
  • These massive structures also provide economic goods and services worth about $375 billion each year.
  • More than 500 million people across the world depend on coral reefs for food, income, and coastal protection from storms and floods.
  • Coral reefs can absorb up to 97% of the energy from waves, storms, and floods, which prevents loss of life, property damage, and soil erosion.
  • Therefore, the absence of coral reefs would not only result in severe ramifications for marine life but also for humans.

What is Coral Bleaching?

  • Most corals contain algae called zooxanthellae ( plant-like organisms) in their tissues.
  • Corals and zooxanthellae have a symbiotic relationship.
  • While corals provide zooxanthellae a safe place to live, zooxanthellae provide oxygen and organic products of photosynthesis that help corals to grow and thrive.
  • Zooxanthellae also give bright and unique colors to corals.
  • Corals are very sensitive to light and temperature and even a small change in their living conditions can stress them.
  • When stressed, they expel zooxanthellae and turn entirely white.
    • This is called coral bleaching.
  • Coral bleaching doesn’t immediately lead to the death of corals.
  • They rather go under more stress and are subject to mortality.
  • Coral bleaching reduces the reproductivity of corals and makes them more vulnerable to fatal diseases.
  • If the bleaching is not too severe, corals have been known to recover.
  • Global mass bleaching of coral reefs is when significant coral bleaching is confirmed in the Atlantic, Indian, and Pacific oceans.
  • Such events are a relatively new phenomenon.
  • The first one took place in 1998 in which 20% of the world’s reef areas suffered bleaching-level heat stress.
  • The next two global bleaching events occurred in 2010 (35% of reefs affected) and between 2014 and 2017 (56% of reefs affected).

What can be the impact of the event?

  • As the global mass bleaching event is still unfolding, its full impact will not be known for a while.
  • With global temperatures soaring, such events are expected to become more frequent and longer.
  • As a result, the world may lose the vast majority of its coral reefs at 1.5 degrees Celsius of warming, and virtually all at 2 degrees.
  • Currently, the average global temperature of the Earth has increased by at least 1.1 degree Celsius since 1850.
  • To curb global warming to no more than 1.5 degrees Celsius, countries need to bring GHG emissions to a net zero by 2050, according to the Paris Agreement.
    The goal, however, is unlikely to be achieved as record levels of GHG emissions have continued to be emitted into the atmosphere.

Mount Ruang

  • 19 Apr 2024

Why is it in the News?

A remote volcano in Indonesia’s outermost region erupted again on April 19 after the crater threw up columns of smoke and lava multiple times this week and forced thousands to evacuate.

About Mount Ruang:

  • Mount Ruang is an active stratovolcano located in the Sangihe Islands arc, North Sulawesi, Indonesia.
  • It is the southernmost volcano in the region, situated on an island that measures 4 by 5 kilometers wide.
  • The summit features a partial lava dome and reaches an altitude of 725 meters.
  • Mount Ruang has experienced multiple eruptions throughout its history, with the most recent ongoing eruption starting on April 18, 2024.
  • The volcano's eruptions often generate ash columns, lava flows, and gas emissions, posing risks to nearby communities.

What is a Stratovolcano?

  • A stratovolcano is a tall volcano shaped like a cone, formed by various layers of materials such as volcanic ash, hardened lava, pumice, and tephra.
  • Stratovolcanoes are steep and have periodic explosive and effusive eruptions, although some have calderas, which are collapsed craters.
  • The highly viscous lava that flows from this type of volcano cools and hardens and in turn, does not spread far.
  • The magma that forms this lava is generally felsic.
  • Stratovolcanoes are more common than shield volcanoes.
    • One of the famous stratovolcanoes is Vesuvius which destroyed Herculaneum and Pompeii in 79 CE.

Formation Of Stratovolcanoes:

  • Stratovolcanoes occur mostly in subduction zones, where the oceanic crust slides under continental crust.
  • The descent of the oceanic plate causes the release of trapped water from hydrated minerals and porous rock, into the mantle rock in the area above the oceanic slab.
  • This process occurs at different pressures depending on the minerals.
  • The water lowers the mantle rock’s melting point, causing partial melting and its rise to the lithosphere forming a temporary pool.
  • The magma then continues to rise through the crust collecting rock rich in silica.
  • The magma finally pools in the magma chamber which is either within or under the volcano.
  • The low pressure at this point causes the volatile compounds such as water, carbon dioxide, and sulfur dioxide dissolved in the magma to escape.
  • When the magma and gas accumulate to a critical level, they overcome the rock blockage of the volcanic cone and erupt violently.

Global Alliance for Incinerator Alternatives (GAIA)

  • 19 Apr 2024

Why is it in the News?

The Global Alliance for Incinerator Alternatives (GAIA) Asia Pacific, in collaboration with other environmental organizations, has called on the Association of Southeast Asian Nations (ASEAN) to take decisive action in response to plastic pollution.

About Global Alliance for Incinerator Alternatives (GAIA):

  • The Global Alliance for Incinerator Alternatives (GAIA) is an alliance of over 1,000 grassroots groups, NGOs, and individuals working towards a transition from a linear, extractive economy to a circular system.
  • GAIA's primary objective is to create a world that prioritizes people's right to a safe and healthy environment, free from toxic pollution and resource depletion.
  • GAIA envisions a just, zero-waste world where communities' rights are respected, and ecological limits are acknowledged. To achieve this vision, the alliance focuses on:
  • Eliminating Incineration: GAIA advocates for alternatives to incineration and promotes waste management practices that protect the environment and public health.
  • Promoting Zero Waste: The alliance supports the adoption of zero-waste strategies, emphasizing waste reduction, reuse, and recycling to conserve resources and reduce pollution.
  • Addressing Plastic Pollution: GAIA recognizes the global plastic pollution crisis and works on initiatives to reduce plastic waste and promote sustainable alternatives.
  • Mitigating Climate Change: GAIA advocates for climate-friendly waste management practices, emphasizing the importance of reducing greenhouse gas emissions from waste disposal.

What is Incineration?

  • Incineration is a waste treatment process that involves burning hazardous materials at high temperatures to destroy contaminants.
    • This process takes place in an "incinerator," a furnace specifically designed to safely burn hazardous materials within a combustion chamber.
  • Various types of hazardous materials can be treated through incineration, including soil, sludge, liquids, and gases.
    • While incineration effectively destroys many harmful chemicals such as solvents, polychlorinated biphenyls (PCBs), and pesticides, it does not destroy metals like lead and chromium.
  • Modern incinerators are equipped with air pollution control mechanisms, such as fabric filters, scrubbers, and electrostatic precipitators.
    • These technologies help remove fly ash and gaseous contaminants generated during the incineration process, mitigating its environmental impact.
    • Despite its benefits in waste treatment, incineration remains a topic of debate due to concerns about residual pollutants and the potential for contributing to greenhouse gas emissions.

Wigner Crystals

  • 19 Apr 2024

Why is it in the News?

In new peer-reviewed research, physicists from Princeton University have confirmed that electrons don’t even need atoms to party together.

What are Wigner Crystals?

  • Wigner Crystals are composed entirely of electrons, unlike the common crystals which are formed by atoms or molecules.  
  • These negatively charged particles, which are known for their role in electricity and chemical bonding, can, under specific circumstances, arrange themselves into a lattice structure, creating a crystal made purely of electrons.
  • The conditions required for the formation of Wigner Crystals are quite stringent.
    • They occur at very low electron densities, where the repulsive Coulomb forces between the electrons dominate over their kinetic energy.
    • This means that the electrons must be spread out enough so that their mutual repulsion causes them to settle into a fixed pattern, minimizing their potential energy.
  • The discovery was made possible by cooling a two-dimensional electron system to near absolute zero and reducing the electron density to a critical level.
    • Under these conditions, the electrons crystallized into a lattice, much like the atoms in a solid.
    • The visualization of this electron lattice marks a monumental step in our understanding of the quantum phases of matter.
  • The implications of this discovery are profound.
    • Wigner Crystals could provide insights into the behavior of electrons in low-density environments, such as those found in semiconductors and other electronic materials.
    • This could lead to the development of new technologies and materials with unique electronic properties.
  • Moreover, the study of Wigner Crystals could shed light on other exotic states of matter and the fundamental principles of quantum mechanics.
  • The confirmation of Wigner Crystals underscores the importance of theoretical physics and how ideas that once seemed purely speculative can lead to tangible discoveries.
  • The realization of Wigner Crystals opens up a new chapter in the study of condensed matter physics.
    •  It stands as a bridge between the abstract world of quantum mechanics and the tangible reality of material science.
    • As we continue to explore the quantum landscape, Wigner Crystals will undoubtedly play a pivotal role in unraveling the mysteries of the electron and the intricate dance of particles that constitute the fabric of our universe.

Added Sugars/Free Sugars

  • 19 Apr 2024

Why is it in the News?

Nestlé’s products for babies in Asia, Africa, and Latin America were found to contain added sugars, while the same products sold in Europe did not have it, according to a recent report.

Highlights of the Report on Nestle:

  • A report by the Swiss organization Public Eye titled 'How Nestlé gets children hooked on sugar in lower-income countries' scrutinized Nestlé for employing varying nutritional standards across its products depending on the country, with unclear sugar content labeling.
  • The report highlighted Nestlé's Cerelac, the world's largest baby cereal brand, which contains significantly higher sugar levels in markets like India, Ethiopia, and Thailand compared to Germany and the UK.
  • Despite sugar not being recommended for infants, Nestlé's baby food products with added sugars are allowed under some countries' national legislation, conflicting with WHO guidelines.
    • WHO recommends reducing daily free sugar intake to less than 10% of total energy intake, preferably less than 5% (around 25 grams per person per day), for better health.
  • Nestlé India claims to have reduced added sugars by up to 30% in their infant cereals portfolio over the last five years, depending on the variant.

What are Added Sugars?

  • Sugar is a simple carbohydrate.
  • Some food items have sugar that is naturally occurring.
    • It is “found in milk (lactose) and fruit (fructose) or any product that contains milk (such as yogurt, milk, or cream) or fruit (fresh, dried) contains some natural sugars.
  • Free sugar or added sugar is added separately to a food item during preparation or processing.
  • It can “include natural sugars such as white sugar, brown sugar, and honey, as well as other caloric sweeteners that are chemically manufactured (such as high fructose corn syrup).

Why is Added Sugar Bad?

  • Excessive consumption of added sugars poses several health risks.
  • Limiting sugar intake is essential for maintaining a healthy diet and preventing various diseases.

The following are some reasons why added sugars can be harmful:

  • Poor Nutritional Balance: Consuming too much-added sugar can lead to increased overall energy intake, often replacing nutritionally adequate calories from healthier food sources.
    • This results in an unbalanced diet lacking essential nutrients, increasing the risk of malnutrition and other health problems.
  • Increased Risk of Non-Communicable Diseases: Excessive sugar consumption is associated with a higher risk of developing non-communicable diseases such as diabetes, obesity, and cardiovascular ailments.
    • These diseases can have severe long-term consequences on overall health and well-being.
  • Unnecessary for Infants and Children: Adding sugar to foods offered to babies and young children is unnecessary and can be highly addictive, establishing unhealthy eating habits that continue into adulthood.
    • Early exposure to sugar is also associated with tooth decay and can contribute to nutrition-based disorders later in life.

Cloud Seeding

  • 18 Apr 2024

Why is it in the News?

The UAE recorded the heaviest rain ever after a severe thunderstorm hit the country on April 15, killing at least one person, causing damage to homes and businesses, and bringing air travel to a standstill in Dubai.

What Led to the Heavy Rains in Dubai?

  • The primary reason for these heavy rains was a storm system, which was passing through the Arabian peninsula and moving across the Gulf of Oman.
  • According to a different report, rains could have been exacerbated by cloud seeding, a process of spraying salt mixtures in clouds that would result in condensation of the cloud and eventually cause rainfall.
    • Several reports quoted meteorologists at the National Center for Meteorology as saying they flew six or seven cloud-seeding flights before the rains.

Is climate change responsible for the event?

  • Some experts have suggested that the soaring global temperatures could also be behind the event.
  • Higher temperatures cause evaporation of water not only from land but also oceans and other water bodies, meaning a warmer atmosphere holds more moisture.
  • Studies have found that for every 1 degree Celsius rise in average temperature, the atmosphere can hold about 7% more moisture.
  • This makes storms more dangerous as it leads to an increase in precipitation intensity, duration, and/or frequency, which ultimately can cause severe flooding.
  • While the average global temperature on the Earth has increased by at least 1.1 degrees Celsius since 1850, the UAE has witnessed an increase of almost 1.5 degrees Celsius in the past 60 years.
    • The increase in temperatures is mainly caused by the rise of heat-trapping greenhouse gas (GHG) emissions since the Industrial Revolution.
  • However, it is extremely difficult to attribute any particular extreme weather event to climate change.
  • It is because there are multiple factors, like patterns of natural climate variability, such as El Niño and La Niña, that contribute to such events.

What is Cloud Seeding?

  • Cloud seeding is a type of weather modification where substances like silver iodide or dry ice are dispersed into clouds to encourage precipitation, such as rain or snow.
  • In countries like the UAE, where temperatures are high and annual rainfall is minimal, cloud seeding is employed to alleviate pressure on limited groundwater sources by enhancing precipitation.

What is UAE's cloud seeding programme?

  • The UAE initiated its cloud seeding program in the late 1990s, making it one of the first Middle Eastern countries to use this technique.
  • Collaborative research with institutions like the National Center for Atmospheric Research (NCAR) and NASA has bolstered their efforts.

How does cloud seeding work?

  • Cloud seeding is a technique where “seeding agents" such as silver iodide or salt are introduced into clouds to stimulate condensation and trigger rainfall.
  • Weather forecasters monitor atmospheric conditions and identify suitable clouds for seeding based on precipitation patterns.
    • This technique can increase rainfall by up to 30-35 percent in clear conditions and 10-15 percent in more humid conditions.

What is the environmental impact of cloud seeding?

  • Cloud seeding alters the precipitation patterns of a region/locality.
    • This may negatively impact neighboring ecosystems, which were to receive rain for the seeded clouds originally.
  • Introducing seeding agents might impact the natural hydrological cycle as it may change the natural soil moisture levels, groundwater recharge, and river flows.
  • Some experts worry about the potential for silver toxicity if cloud seeding becomes widespread.
    • Silver iodide is a common seeding agent.
    • Silver toxicity could pose risks to aquatic life and soil health.
  • Therefore, even with the promise cloud seeding holds, responsible stewardship and thorough evaluation of its environmental impacts are crucial.

  • ICFRE, in collaboration with experts, is developing the Green Credit Registry and trading platform to facilitate the registration and trading of Green Credits.
  • Entities and individuals must register their activities with the government to earn Green Credits.
  • Verification of activities will be conducted by a designated agency, with self-verification available for small projects.

Programme Impact:

  • The GCP strives to encourage environmentally beneficial actions by creating tradable green credits through a market-oriented approach.
  • These green credits can be traded on a domestic market platform, providing further incentives for positive environmental actions.
  • Additionally, if the generation of green credits results in measurable reductions or removals of carbon emissions, they may also qualify for carbon credits.

Programme Adjustments:

  • In response to concerns regarding the potential misuse of the GCP for profit-driven tree planting, the government has emphasized the importance of prioritizing ecosystem restoration over mere tree planting.
  • Indigenous species will be preferred, and naturally occurring seedlings will be preserved.
  • The previous requirement of a minimum of 1,100 trees per hectare to qualify as a reforested area has been revised, with States now tasked to define specific criteria.
  • State forest departments will be responsible for the actual implementation of afforestation efforts.

Recently, the RBI approved FIIs such as insurance companies, pension funds, and sovereign wealth funds to invest in India's Sovereign Green Bonds (SGrBs), which finance projects aiming to advance India's shift to a low-carbon economy.

What are Green Bonds?

  • Green bonds are bonds issued by any sovereign entity, inter-governmental groups or alliances, and corporates with the aim that the proceeds of the bonds are utilised for projects classified as environmentally sustainable.
  • The framework for the sovereign green bond was issued by the government on November 9, 2022.

Why are these bonds important?

  • Over the last few years, Green Bonds have emerged as an important financial instrument to deal with the threats of climate change and related challenges.
  • According to the International Finance Corporation (IFC), a World Bank Group’s institution, climate change threatens communities and economies, and it poses risks to agriculture, food, and water supplies.
  • A lot of financing is needed to address these challenges.
  • It’s critical to connect environmental projects with capital markets and investors and channel capital towards sustainable development – and Green Bonds are a way to make that connection.

When did Govt plan these bonds?

  • In August 2022, the government said it stands committed to reducing the Emissions Intensity of GDP by 45 percent from the 2005 level by 2030 and achieving about 50 percent cumulative electric power installed capacity from non-fossil fuel-based energy resources by the same year.
  • In line with the commitment to significantly reduce the carbon intensity of the economy, the Union Budget 2022-23 announced to issue of Sovereign Green Bonds.
  • The country’s climate actions have so far been largely financed from domestic resources and it is now targeting the generation of additional global financial resources.
  • The issuance of the Sovereign Green Bonds will help the Indian government in tapping the requisite finance from potential investors for deployment in public sector projects aimed at reducing the carbon intensity of the economy.

Where will the proceeds go?

  • The government will use the proceeds raised from SGrBs to finance or refinance expenditure (in parts or whole) for various green projects, including renewable energy, clean transportation, energy efficiency, climate change adaptation, sustainable water and waste management, pollution and prevention control, and green buildings.
  • In renewable energy, investments will be made in solar, wind, biomass, and hydropower energy projects.

Gaia-BH3

  • 17 Apr 2024

Why is it in the News?

European astronomers have made a groundbreaking discovery by identifying Gaia-BH3, a colossal black hole located just 2,000 light years away from Earth within the Milky Way, revolutionizing our comprehension of star formation.

What Is Gaia-BH3?

  • Gaia-BH3, a stellar black hole in the Milky Way galaxy, has been identified as the most massive one discovered to date.
  • The European Space Agency's Gaia mission detected Gaia-BH3 due to its distinctive 'wobbling' effect on a companion star orbiting it.
  • Through the use of the Very Large Telescope at the European Southern Observatory in Chile's Atacama Desert and other ground-based observatories, researchers confirmed its enormous mass.
  • With a mass 33 times greater than our sun, Gaia-BH3 is situated in the Aquila constellation at a distance of 1,926 light-years from Earth, earning it the title of the second-closest known black hole.
  • Gaia BH1, located about 1,500 light-years away, remains the closest known black hole to Earth with a mass approximately 10 times that of our sun.
  • While Gaia-BH3 holds the distinction of being the most massive stellar black hole in our galaxy, it pales in comparison to Sagittarius A*, the supermassive black hole at the Milky Way's center, which boasts a staggering mass of roughly 4 million times that of the sun.

Difference Between Stellar and Supermassive Black Holes:

  • Stellar and supermassive black holes are two distinct types of cosmic phenomena, each with unique characteristics and origins.
  • Stellar-mass black holes result from the gravitational collapse of a single star or the merger of two neutron stars, resulting in masses comparable to stars.
    • Their mass typically ranges from three to fifty times that of our sun.
  • In contrast, supermassive black holes boast a mass exceeding 50,000 times the solar mass, often reaching into the millions or billions.
    • The formation of supermassive black holes remains a mystery to scientists, as they are too massive to have formed from a single star's collapse.
  • Their consistent presence at the center of galaxies suggests a potential connection to galactic formation.
  • While our understanding of these cosmic giants continues to evolve, one thing is clear: both stellar and supermassive black holes are awe-inspiring fixtures in our universe.

Hydrocarbon Extraction: Processes, Methods, Environmental Impact

  • 16 Apr 2024

Why is it in the News?

Over millennia, mighty geological processes in the earth’s crust heated and compressed together pieces of life forms that had been dead for a while.

What Is a Hydrocarbon?

  • The term hydrocarbon refers to an organic chemical compound that is composed exclusively of hydrogen and carbon atoms.
  • Hydrocarbons are naturally occurring and form the basis of crude oil, natural gas, coal, and other important energy sources.
  • They are highly combustible and produce carbon dioxide, water, and heat when they are burned.
  • As such, hydrocarbons are highly effective as a source of fuel.

Where are Hydrocarbons Located?

  • Hydrocarbons, such as natural gas, coal, crude oil, and petroleum, are typically found in underground rock formations within reservoirs.
    • These reservoirs form when less resistant rocks are overlayed by more resistant ones, creating a lid that traps hydrocarbons beneath.
    • Petroleum geology tools, methods, and techniques are used to assess these rocks for their porosity and permeability, determining how much hydrocarbons they can hold and how easily they can flow through them.
  • Kerogen, lumps of organic matter, is the primary source of hydrocarbons within these subterranean rocks.
    • Kerogen can be deposited from lacustrine, marine, or terrestrial ecosystems.
    • Over time, surrounding rocks can become warmer and more compactified, exerting forces on kerogen that cause it to break down into various hydrocarbons, such as waxy oils, light oils, gas, and coal.
  • Petroleum geologists locate and characterize kerogen-containing source rocks, studying their geophysical and thermal properties.
    • They conduct modeling activities, analyze observational data, and dig exploration wells to estimate hydrocarbon quantities.
    • Once a profitable hydrocarbon source is identified, drilling can commence.

How are the Hydrocarbons Accessed?

  • Drilling and reservoir engineers employ various methods to extract hydrocarbons efficiently without damaging the reservoir.
    • The process begins with creating a production well, strategically positioned to maximize drainage.
    • A drilling machine, consisting of a drill pipe, drill collars, and a drill bit, is used to create the well.
  • As drilling progresses, steel casings are lowered into the tunnel, and cement slurry is pumped into the gap between the casings and the tunnel's outer edge.
    • The solidifying cement prevents cave-ins and blocks surrounding fluids from entering the well.
    • The tunnel is filled with drilling fluid, which cools the drill bit and carries rock fragments to the surface for removal.
  • Controlling drilling fluid pressure is crucial to prevent hydrocarbon eruptions. Modern drilling setups use blowout preventers to manage such events.
    • Meanwhile, mud-logging records rock properties at different depths, aiding the process.
  • Drill pipes can be extended or replaced as needed during the drilling process, which is now conducted by advanced drilling rigs equipped with power sources.
    • Offshore rigs feature additional facilities to ensure stability and facilitate extraction through the water column.

How are the Hydrocarbons Extracted?

  • Upon drilling the production well, it must be prepared for hydrocarbon drainage, called completion.
    • Engineers remove the drill string and perforate the casing, allowing hydrocarbons to flow into the well and rise to the surface.
    • A narrower tube encourages one-directional flow and controls outflow using valves.
  • When pressure differences are insufficient for natural fluid ascent, pump jacks or other artificial lift methods can aid extraction.
    • Workovers may be required to maintain or improve production efficiency over time.
    • Extraction phases include primary (relying on natural processes), secondary (inducing artificial pressure), and tertiary (enhanced recovery methods, like steam injection) phases, each contributing to the total hydrocarbon yield.

What Happens When a Well is Depleted?

  • Wells may cease extraction before depletion if operations become unprofitable.
    • Properly plugging abandoned wells prevents hydrocarbon and gas leakage into surrounding environments, yet deterioration and failure of plugs remain concerns.
    • Decommissioning is the most thorough but often expensive solution.
  • Improperly abandoned wells contribute significantly to methane emissions, alongside emissions from extraction and component use.
    • A 2018 study estimated that 9,000 oilfields in 90 countries released 1.7 billion tonnes of carbon dioxide in 2015 alone.
  • Overall, the pursuit of subterranean hydrocarbons, including natural gas, coal, crude oil, and petroleum, employs various extraction methods.
    • However, it is essential to consider the environmental impact and sustainability of these operations.

Thiruvalluvar

  • 16 Apr 2024

Why is it in the News?

Seeking to connect with the people of Tamil Nadu where his party is trying to gain a foothold, Prime Minister Narendra Modi recently announced that the BJP will work towards building Thiruvalluvar cultural centers all over the world.

Who was Thiruvalluvar?

  • Thiruvalluvar, the author of the revered 'Thirukkural' or 'Sacred Couplets', remains a figure of historical debate.
  • His exact period and religious affiliation are uncertain, with proposed dates ranging from the 3rd or 4th century CE to the 8th or 9th century.
    • Various groups regard him as a Hindu sage, a Jain sage, or a Dravidian saint with no religious identifiers except his Dravidian heritage.
  • Accounts of Thiruvalluvar's origins are diverse.
  • In Edward Jewitt Robinson's 1873 book, 'Tamil Wisdom: Traditions Concerning Hindu Sages and Selections from their Writings', he described Thiruvalluvar as a "Pariah" with a mother from "the low class" and a possibly Brahmin father.
  • According to this narrative, Thiruvalluvar was found in a grove near a Shiva temple in Mayilapur and was taken in by the wife of a high-ranking Velalan before being entrusted to a "Pariah family."
  • Despite the ambiguity surrounding Thiruvalluvar's identity, his wisdom-laden verses in 'Thirukkural' continue to influence and inspire generations across religious and cultural divides.

Why does Thiruvalluvar matter?

  • Thiruvalluvar, affectionately called Valluvar by Tamils, is revered as a cultural and moral icon across caste and religious lines.
    • His 'Thirukkural', a compilation of 1,330 couplets, is an integral part of Tamil culture, comparable to the Bhagavad Gita or Ramayana in North Indian Hindu households.
    • It serves as a foundational text for ethical living and tracing Tamil cultural roots.
  • Beyond Tamil Nadu, Thiruvalluvar's wisdom is celebrated in the context of ancient India's rich philosophical heritage, emphasizing morality and ethics.
    • His enduring influence is evident as successive Indian finance ministers reference his teachings in annual Budget speeches.
  • However, competing claims to Thiruvalluvar's legacy have sparked controversy, such as the 2019 debate surrounding the BJP's depiction of him in saffron robes instead of traditional white garments.
    • Despite these disputes, the profound impact of Thiruvalluvar's teachings continues to resonate across various cultures and languages, fostering unity and moral guidance.

Why Are Political Parties Asserting Thiruvalluvar's Legacy?

  • Political parties, both national and regional, have long vied for ownership of Thiruvalluvar's legacy. For instance, the BJP, with a limited grassroots presence in Tamil Nadu, seeks to bolster its standing through the appropriation of Tamil saints and icons.

UN Permanent Forum on Indigenous Issues

  • 16 Apr 2024

Why is it in the News?

As the 23rd session of the UN Permanent Forum on Indigenous Issues begins in New York, United States on April 15, participants pointed out that though recognition of indigenous territories is increasing, it is not happening at the pace the planet needs.

About the UN Permanent Forum on Indigenous Issues:

  • Established in 2000, the UNPFII serves as an advisory body to the United Nations Economic and Social Council (ECOSOC), focusing on indigenous issues related to economic and social development, culture, environment, education, health, and human rights.
  • Alongside the Expert Mechanism on the Rights of Indigenous Peoples and the Special Rapporteur on the Rights of Indigenous Peoples, the UNPFII is one of three UN entities mandated to address Indigenous Peoples' issues.

The Permanent Forum's primary objectives include:

    • Providing expert advice and recommendations to the Council, United Nations programs, funds, and agencies.

Long Period Average (LPA) Rainfall

  • 16 Apr 2024

Why is it in the News?

Ministry of Earth Sciences announced recently that the country as a whole is likely to receive above-normal rainfall during the southwest monsoon from June to September 2024.

What is the Long Period Average (LPA) of Rainfall?

  • The India Meteorological Department (IMD) predicts a “normal”, “below normal”, or “above normal” monsoon in relation to a benchmark “long period average” (LPA).
  • According to the IMD, the “LPA of rainfall is the rainfall recorded over a particular region for a given interval (like month or season) average over a long period like 30 years, 50 years, etc”.
  • While this quantitative benchmark refers to the average rainfall recorded from June to September for the entire country, the amount of rain that falls every year varies from region to region and from month to month.
  • Therefore, along with the countrywide figure, the IMD also maintains LPAs for every meteorological region of the country — this number ranges from around 61 cm for the drier Northwest India to more than 143 cm for the wetter East and Northeast India.

Why LPA is Needed?

  • The IMD records rainfall data at more than 2,400 locations and 3,500 rain-gauge stations.
    • Because annual rainfall can vary greatly not just from region to region and from month to month, but also from year to year within a particular region or month, an LPA is needed to smooth out trends so that a reasonably accurate prediction can be made.
  • A 50-year LPA covers for large variations in either direction caused by freak years of unusually high or low rainfall (as a result of events such as El Nino or La Nina), as well as for the periodic drought years and the increasingly common extreme weather events caused by climate change.

What is the Range of Normal Rainfall?

  • The IMD maintains five rainfall distribution categories on an all-India scale. These are:
    • Normal or near normal, when the percentage departure of actual rainfall is +/-10% of LPA, that is, between 96-104% of LPA;
    • Below normal, when the departure of actual rainfall is less than 10% of LPA, that is 90-96% of LPA;
    • Above normal, when actual rainfall is 104-110% of LPA;
    • Deficient, when the departure of actual rainfall is less than 90% of LPA; and
    • Excess, when the departure of actual rainfall is more than 110% of LPA.

Space Tourism

  • 15 Apr 2024

Why is it in the News?

Entrepreneur and pilot on the NS-25 mission of Blue Origin — a company founded by Jeff Bezos, who is also Gopi Thotakura is set to become the first Indian to venture into space as a tourist the founder of Amazon.

Context:

  • In recent years, space tourism has grown by leaps and bounds.
  • The space tourism market was valued at $848.28 million.
  • It is expected to grow to $27,861.99 million by 2032.
  • However, there are several challenges, such as high cost, and environmental concerns, that may limit the industry’s growth.
  • The NS-25 mission, which Gopi Thotakura is a part of, is a sub-orbital mission. Thotakura and his other crew members will be taken to outer space via New Shepard, a fully reusable sub-orbital launch vehicle developed specifically for space tourism by Blue Origin.

What is Space Tourism?

  • Space tourism is essentially a section of the aviation sector that seeks to provide tourists with the opportunity to become astronauts and experience space travel for recreational, leisure, or business purposes.
  • There are two main types of space tourism, sub-orbital and orbital.
  • The sub-orbital spacecraft takes passengers just beyond the Kármán line (it lies nearly 100 kilometers above our heads and is considered to be the boundary between Earth’s atmosphere and outer space).
    • The passengers get to spend a few minutes in outer space and then come back to Earth.
  • The orbital spacecraft, on the other hand, takes passengers much further than the Kármán line.
    • Usually, passengers can spend from a couple of days to more than a week at an altitude of nearly 1.3 million feet.
  • In September 2021, Space X’s Falcon 9 took four passengers to an altitude of 160 km where they spent three days orbiting the Earth.

What are the Challenges?

  • Currently, space tourism is expensive as a passenger generally has to pay at least a million dollars to reach outer space.
    • This amount is out of reach for almost everyone.
  • Moreover, several studies have pointed out that space tourism may lead to environmental damage as rockets emit gaseous and solid chemicals directly into the upper atmosphere.
  • A 2022 study done by researchers found that the soot emissions from rocket launches are far more effective at warming the atmosphere compared to other sources.
  • Safety is also a concern when it comes to space tourism.
  • Despite high safety standards, a total of 676 people have flown into space and 19 of them have died, as of November 2023, according to a report by Astronomy Magazine.
    • This means that approximately 3% of astronauts died during their space flight which is quite a high fatality rate.
