Fuego Volcano
A powerful eruption of the Volcan de Fuego in Guatemala recently has sent shockwaves through the region, with strong explosions, incandescent material, and pyroclastic flows threatening nearby communities.

About Fuego Volcano:

  • Volcan de Fuego, which translates to "Volcano of Fire" in Spanish, is one of three large stratovolcanoes overlooking Guatemala's former capital, Antigua.
    • Guatemala lies on the Pacific “Ring of Fire” and experiences frequent seismic and volcanic activity.
  • Fuego is one of Central America's most active volcanoes.
  • It has a long history of violent eruptions, with records dating back to the 16th century.
    • A deadly eruption in 2018 claimed 194 lives and left 234 people missing.
  • The volcano's eruptive style is characterised by explosive events, lava flows, and pyroclastic flows, which pose major threats to nearby populations.

What is a Stratovolcano?

  • It is a tall, steep, and cone-shaped type of volcano.
  • Unlike flat shield volcanoes, they have higher peaks. At the peak, stratovolcanoes usually have a small crater.
  • They are usually about half-half lava and pyroclastic material, and the layering of these products gives them their other common name of composite volcanoes.
  • They are typically found above subduction zones, and they are often part of large volcanically active regions, such as the Ring of Fire that frames much of the Pacific Ocean.
  • Stratovolcanoes comprise the largest percentage (~60%) of the Earth's individual volcanoes.
  • Most are characterized by eruptions of andesite and dacite, lavas that are cooler and more viscous than basalt.
  • These more viscous lavas allow gas pressures to build up to high levels. Therefore, these volcanoes often suffer explosive eruptions.

POLG Disease
A 22-year-old young prince of Luxembourg, Prince Frederik, recently died from a rare genetic disease called POLG.

About POLG Disease:

  • It is a genetic mitochondrial disorder that prevents the body’s cells from producing adequate energy, which in turn can cause multiple organ dysfunctions and failures.
  • The disease affects multiple organs of the body, primarily the brain, nerves, muscles, and liver.
  • It could also affect a person’s vision due to the involvement of affected brain structures.
  • People with POLG “likely end up bedridden and unable to function in so many of those activities of daily living.
  • Causes:
    • The condition affects mitochondria, the “powerhouse" of the cell, which converts food into ATP (Adenosine triphosphate), the primary source of energy in living cells of a body.
    • Mitochondria contain their own DNA, which requires a specific enzyme to replicate, found in the host cell’s POLG and POLG2 genes.
    • Mutations in these genes therefore impact the ability for mitochondria to replicate.
  • Symptoms:
    • A person can see symptoms, from mild to severe, starting from early childhood to adulthood.
    • The most frequent symptoms include muscle weakness, ophthalmoplegia (weakness or paralysis of the eye), epilepsy, and liver failure.
    • POLG also affects neurological function and impacts a person’s ability to balance, talk, and walk, and it causes seizures and more.
  • Treatment:
    • There is currently no cure for POLG.
    • Available treatment for the POLG focuses on managing the symptoms and quality of life.

Plastic Ice
Scientists have confirmed the existence of a fourth form of water, Plastic Ice VII, an exotic phase of ice that forms under extreme conditions.

About Plastic Ice:

  • Under normal conditions, water exists in three phases: solid (ice), liquid (water), and gas (vapour or steam). Unlike ordinary ice, Plastic Ice VII allows water molecules to rotate freely within a rigid crystalline structure.
  • This phase was first predicted in 2008, but scientists have now provided solid evidence of its existence using advanced neutron-scattering experiments at the Institut Laue-Langevin in France.
  • The unique structure of Plastic Ice VII forms at pressures exceeding three gigapascals (GPa), about 30,000 times atmospheric pressure on Earth, and temperatures above 450 Kelvin (177°C).

How Was It Discovered?

  • Researchers used quasi-elastic neutron scattering (QENS) and diamond-anvil cells to study tiny high-pressure samples. These techniques allowed them to analyze molecular motion at the atomic scale.
  • Their findings confirm that while Plastic Ice VII retains a crystalline structure, its molecules rotate in specific, preferred directions.

Significance of Plastic Ice Discovery:

  • This discovery has profound implications for planetary science. Ice VII, an earlier known phase, exists deep inside the icy moons of Jupiter and Saturn, such as Callisto, Ganymede, and Titan.
  • Now, the confirmation of Plastic Ice VII suggests that water in extreme environments behaves in even more complex ways than previously thought.
  • Understanding this exotic ice could help scientists explore whether extreme planetary conditions could support life and how water influences the structure of celestial bodies.
  • Scientists believe this discovery could lead to new insights in materials science, planetary exploration, and even the development of futuristic technologies that use extreme pressure conditions.

Kuki Tribe
An armoured vehicle of the central security forces came under heavy attacks by protesters from the Kuki tribes in Manipur on the first day of the Centre's order to ensure free movement of people in the crisis-hit state

About Kuki Tribe:

  • The Kukis are an ethnic group including multiple tribes originally inhabiting the Northeastern States of India, including Manipur, Mizoram and Assam; parts of Myanmar, and Sylhet district and Chittagong hill tracts of Bangladesh.
  • The Chin people of Myanmar and the Mizo people of Mizoram are kindred tribes of the Kukis and are collectively known as the Zo people.
  • Notably, Kuki is not a term coined by the ethnic group itself, the tribes associated with it came to be generically called Kuki under the colonial rule, and were further divided by the British into ‘old Kukis’ and ‘new Kukis’.
  • The Kukis have a rich cultural heritage, with institutions like Sawm and Lawm playing significant roles in their society.
    • Sawm is a community center for boys where they learn under the guidance of elders, while Lawm is a youth club that fosters social activities and practical skills
  • The Kukis traditionally engaged in shifting or Jhum cultivation in the forested hills, which allowed them to expand their settlements through the wooded areas over generations.
  • Their expansionist land ownership patterns due to Jhum cultivation put them at odds with the Nagas, who practised territorial agriculture, and the Meiteis, who lived in the cultivated valley areas.

Kuki Rebellion of 1917-19:

  • The first resistance to British hegemony by the Kuki people was the Kuki Rebellion of 1917-19, after which their territory was subjugated by the British and divided between the administrations of British India and British Burma.
  • Up until their defeat in 1919, the Kukis had been an independent people ruled by their chieftains.

La Nina
Climate change is intensifying, and the cooling effects of La Niña may weaken in a warmer future, climate scientists warn, citing current heat trends across much of the country.

About La Nina:

  • La Niña is a climate pattern that describes the cooling of surface-ocean waters along the tropical west coast of South America.
  • It is considered to be the counterpart to El Niño, which is characterized by unusually warm ocean temperatures in the equatorial region of the Pacific Ocean.
  • Together, La Niña and El Niño are the "cold" (La Niña) and "warm" (El Niño) phases of the El Nino-Southern Oscillation (ENSO). ENSO is series of linked weather- and ocean-related phenomena.
  • La Niña events are indicated by sea-surface temperature decreases of more than 0.5 degrees Celsius (0.9 degrees Fahrenheit) for at least five successive three-month seasons.

Causes:

  • La Niña is caused by a build-up of cooler-than-normal waters in the tropical Pacific, the area of the Pacific Ocean between the Tropic of Cancer and the Tropic of Capricorn.
  • Unusually strong, eastward-moving trade winds and ocean currents bring this cold water to the surface, a process known as upwelling. Upwelling can cause a drastic drop in sea-surface temperature.

Effects:

  • Impact on Air Pressure and Rainfall: La Niña lowers air pressure over the western Pacific, leading to increased rainfall. South Asia experiences stronger summer monsoons, benefiting agriculture in India and Bangladesh.
  • Risk of Flooding in Australia: While La Niña supports agriculture in South Asia, strong events can cause severe flooding in northern Australia due to excessive rainfall and low-pressure systems.
  • Global Rainfall Patterns: La Niña brings more rain to southeastern Africa and northern Brazil. In contrast, it increases air pressure over the central and eastern Pacific, causing dry conditions.
  • Drier Conditions in Some Regions: Regions like the west coast of tropical South America, the Gulf Coast of the US, and the pampas of South America experience reduced rainfall and dry spells during La Niña.
  • Boost to the Fishing Industry: Upwelling caused by La Niña brings cold, nutrient-rich waters to the surface, supporting plankton growth. This benefits fish populations and predators like sea bass.
  • Duration and Seasonal Peak: La Niña events usually last between one and three years, whereas El Niño typically lasts less than a year. Both tend to peak during the Northern Hemisphere winter.

Trade-to-Trade (T2T) Segment in Stock Markets
The Securities and Exchange Board of India (SEBI) is considering a major revamp of short-selling regulations, potentially allowing it for all stocks excluding those in the trade-to-trade (T2T) segment.

About Trade-to-Trade (T2T) Segment:

  • T2T stocks or Trade-to-Trade stock means stocks that must be delivered in order to be traded (T+2 settlement).
  • This implies that such equities cannot be traded intraday or, in the case of Buy Today Sell Tomorrow, on a daily basis.
  • This means if you acquire T2T stocks today, you won’t be able to sell them until the settlement takes place.
    • Your order will be refused if you try to sell these shares the same day or before they are in the Demat account.
  • Stocks are put under the T2T segment by the exchanges based on criteria such as their price-earnings ratio, price variations, market capitalisation, etc.
  • Stocks that are very volatile or have irregular price movements are monitored by exchanges in cooperation with the market regulator, SEBI.
  • They put stocks in the T2T section to shield regular investors from being caught up in the volatility and to limit unwarranted speculation on such equities.
  • On a bi-weekly basis, exchanges relocate stocks to the T2T section, and they are shifted in and out of the segment depending on quarterly evaluations.

About Preventive Detention:

  • Preventive detention refers to the detention of an individual without a trial or conviction by a court.
  • The primary objective of preventive detention is not to punish an individual for a past offence but to prevent them from committing an offence in the future.
  • Preventive detention laws are enacted by governments to ensure public safety and maintain social order.
  • Constitutional Provisions and Safeguards:
    • Article 22 of the Indian Constitution grants protection to individuals who are arrested or detained.
    • It has two parts—the first part deals with cases of ordinary law, which includes situations where an individual is detained as part of a criminal investigation.
    • The second part deals with cases of preventive detention law, which pertains to the detention of individuals without a trial or conviction.
    • Article 22(4) states that no law providing for preventive detention shall authorise the detention of a person for a longer period than three months unless an Advisory Board reports sufficient cause for extended detention.
    • The detainee is entitled to know the grounds of his detention. The state, however, may refuse to divulge the grounds of detention if it is in the public interest to do so.
    • The detaining authorities must give the detainee earliest opportunities for making representation against the detention.
  • Who can make laws under Preventive Detention?
    • Parliament has the exclusive power to enact a law for preventive detention for reasons connected with defence, foreign affairs, or security of India.
    • Both Parliament and State Legislature have powers to enact a law for preventive detention for reasons related to the maintenance of public order or the maintenance of supplies or services essential to the community.
  • Laws that provide for Preventive Detention:
    • In India, various laws provide for preventive detention, including the National Security Act (NSA) of 1980, the Unlawful Activities (Prevention) Act (UAPA) of 1967, and state-specific laws like the Maintenance of Internal Security Act (MISA) and the Public Safety Acts (PSA) in certain states.
    • Under these laws, authorities can detain an individual for a specific period, typically up to 12 months, without presenting formal charges or conducting a trial.

What is Shingles Disease?
A new global survey shows that 56.6% of Indian participants aged 50 and above know little to nothing about shingles, although more than 90% of adults above 50 years have this virus in their body, and are vulnerable to the disease.

About Shingles Disease:

  • Shingles (herpes zoster) is a viral infection that causes an outbreak of a painful rash or blisters on the skin.
  • The rash most often appears as a band of rashes or blisters in one area of the body.
  • Shingles can occur anywhere on the body.
  • The risk of shingles goes up as you get older and it is most common in people over age 50.

● What Causes Shingles?

  • It's caused by the varicella-zoster virus, which is the same virus that causes chickenpox.
  • When you have chickenpox as a child, your body fights off the varicella-zoster virus and the physical signs of chickenpox fade away, but the virus always remains in your body.
  • In adulthood, sometimes the virus becomes active again.
  • This time, the varicella-zoster virus makes its second appearance in the form of shingles.

 

  • Is Shingles Contagious?
    • Shingles is not contagious, but the virus can be spread to someone who has never had chickenpox.
    • This will cause chickenpox, not shingles.
  • Symptoms:
    • The symptoms of shingles can include pain, itching, tingling, and numbness, as well as fever, headache, chills, and fatigue.
    • Shingles isn't life-threatening. But it can be very painful.
    • The most common complication is postherpetic neuralgia. This is a painful condition that causes shingles pain for a long time after your blisters have cleared.
  • Prevention: There is a vaccine called Shingrix available, which helps in preventing shingles and its complications.
  • Treatment: There is no cure for shingles. Antiviral medications can reduce the severity and duration of shingles, especially if started early.

    • Though rare, it can also spread through rodent bites or scratches.
  • Symptoms:
    • Symptoms often start with fatigue, fever, and muscle aches, followed by headaches, dizziness, chills, and abdominal issues.
    • If respiratory symptoms develop, the mortality rate is approximately 38%.
  • Treatment: There is no specific treatment for hantavirus infection, but early medical care can help if serious disease develops.

Dulcibella camanchaca
A new deep-sea predator has been discovered in the Atacama Trench, though incredibly small in size, possesses lethal hunting abilities that make it a formidable force in its underwater ecosystem.

About D. camanchaca:

  • It is a newly discovered amphipod, a shrimp-like marine creature, marking the first known predatory amphipod in the hadal zone—depths exceeding 6,000 meters below the ocean surface.
  • Unlike most amphipods that feed on detritus, it is an active predator, using specialized appendages to catch and consume other organisms.
    • This behaviour is rare among deep-sea creatures, which typically rely on scavenging due to the scarcity of food.
  • camanchaca has adapted to freezing temperatures and immense pressure, which exceeds 1,000 times the atmospheric pressure at sea level.
  • The genus name Dulcibella is inspired by Dulcinea, a character from Don Quixote. However, since this name was already assigned to another species, researchers chose camanchaca, meaning "darkness" in some South American languages—a fitting name for a creature that thrives in total darkness.

Atacama Trench:

  • The Atacama Trench stretches along the eastern South Pacific Ocean, plunging to depths exceeding 8,000 m off the coast of northern Chile.
  • It is part of the hadal zone, a region characterised by intense pressure, near-freezing temperatures, and complete darkness.
  • It is one of the most geographically isolated hadal features and is situated below eutrophic surface waters and characterized by high sediment loads.

  • Objective: The Convention prohibits all use, production, transfer and stockpiling of cluster munitions. States Parties are committed to the full universalization of the Convention and to promote its norms, as well as to fully implement it.
  • Membership Status: The convention has 112 member states and 12 signatories yet to ratify it, while India, the U.S., Russia, China, Ukraine, and Israel have not signed due to military and strategic concerns.
  • The Convention on Cluster Munitions (CCM) was born out of a collective determination to address the humanitarian consequences and unacceptable harm to civilians caused by cluster munitions.
  • Its implementation contributes to advancing the achievement of the UN Sustainable Development Goals and the promotion of international peace and security, human rights and international humanitarian law.

Loss and Damage Fund
In a setback to global climate justice efforts, the United States has withdrawn from the loss and damage fund aimed at compensating developing countries for the damages caused by climate change.

About Loss and Damage Fund (LDF):

  • Loss and damage refers to the negative consequences that arise from the unavoidable risks of climate change, like rising sea levels, prolonged heatwaves, desertification, the acidification of the sea and extreme events, such as bushfires, species extinction and crop failures.
  • Establishment: The Fund was established at the 2022 UNFCCC Conference (COP27) in Egypt, to provide financial support to regions suffering both economic and non-economic losses caused by climate change.
  • Developing countries, particularly small island states that face the greatest threats from climate impacts, had been demanding financial assistance in case of climate-related disasters, arguing that they were having to suffer due to a problem created by rich and developed countries.
  • About $750 million has so far been promised for the fund, of which the US has contributed $17.5 million. The US, in fact, is one of the very few countries to have already transferred its committed amount to the Fund.
  • The LDF is overseen by a Governing Board that determines how the fund’s resources are disbursed, with the World Bank serving as the interim trustee tasked with hosting the fund for four years.

Paris Agreement:

  • The Paris Agreement is an international accord that was adopted by nearly every country in 2015 to address climate change and its adverse effects.
  • Its primary goal is to substantially reduce greenhouse gas (GHG) emissions in a bid to limit global warming in this century to “well below” 2 degrees Celsius above pre-industrial levels while pursuing the means to curb warming to 1.5 degrees.
  • The agreement mentions the safer limit of 1.5 degrees based on a fact-finding report which found that breaching the threshold could lead to “some regions and vulnerable ecosystems” facing high risks, over an extended, decades-long period.
  • The treaty also requires all Parties (countries which have joined the agreement) to state every five years what they are doing to tackle climate change — what is known as their nationally determined contribution (NDC).

Ponzi Scheme
The Enforcement Directorate seized a business jet at Hyderabad airport in a ₹850 crore Ponzi scam probe against a Hyderabad-based company and its promoters.

About Ponzi Scheme:

  • A Ponzi scheme is an investment scam that pays early investors with money taken from later investors to create an illusion of big profits. A Ponzi scheme promises a high rate of return with little risk to the investor.
  • Origin: The Ponzi scheme gets its name from a swindler named Charles Ponzi, who in 1920 became a millionaire by promoting a nonexistent investing opportunity.
  • Working:
    • It relies on word-of-mouth, as new investors hear about the big returns earned by early investors.
    • Inevitably, the scheme collapses when the flow of new money slows, making it impossible to keep up the payments of alleged profits.
    • A Ponzi scheme is similar to a pyramid scheme in that use new investors' funds to pay earlier backers.
    • A pyramid scheme usually relies on rewarding early participants to recruit more participants but collapses when the supply of potential participants dwindles.
  • Notable Ponzi Scams in India:
    • Saradha Scam (2013): A multi-crore chit fund scam in West Bengal that defrauded lakhs of investors.
    • Rose Valley Scam: A larger scam than Saradha, involving over Rs 15,000 crore.
    • SpeakAsia (2011): A pyramid-like scheme posing as an online survey business.
    • PACL (Pearl Agro Corporation Limited) Scam: Collected Rs 49,100 crore from investors under the guise of land investments.

Safeguards against Ponzi Schemes in India:

  • Ponzi schemes are banned under the Prize Chit and Money Circulation (Banning) Act, 1978, a Central Act enforced by State governments.
  • Additionally, the Unregulated Deposit Schemes Act, 2019 explicitly bans Ponzi schemes, further strengthening legal action against such frauds.
  • These are also dealt with by the Enforcement Directorate under the Prevention of Money Laundering Act, 2002.
