In news: Total Solar Eclipse

Why in the news?

A rare Total Solar Eclipse will be visible across North America on April 8.

What are Eclipses?

  • Eclipses are astronomical events that occur when the sun, moon, and Earth align in specific ways.
  • There are two primary types of eclipses: solar and lunar.
  1. A solar eclipse happens when the moon comes between the sun and Earth during a new moon, blocking out the sun’s light.
  2. Conversely, a lunar eclipse occurs when the Earth is positioned between the sun and the moon during a full moon, casting a shadow on the moon.

What is a Total Solar Eclipse?

  • During a total solar eclipse, the moon passes between the sun and Earth, entirely covering the face of the sun along a small path of our planet’s surface.
  • This is called the “path of totality.”
  • The daytime sky turns dark, similar to dusk or dawn, and nocturnal animals have been known to wake up, confused into believing night has arrived.

Stages of a Total Solar Eclipse

A total solar eclipse unfolds in several distinct stages.

  1. It starts with a partial eclipse phase as the moon begins to pass between Earth and the sun, partially blocking it and leaving the sun looking like it has a crescent shape.
  2. In the subsequent Baily’s Beads phase, points of light from the sun shine around the moon’s edges because of the irregular lunar topography, producing small beads of light.
  3. In the diamond ring phase, a single bright spot appears along the lunar edge even as the sun’s atmosphere leaves a ring of light around the moon. This phenomenon precedes totality.
  4. After totality, the other phases repeat as the moon keeps moving along its path until the eclipse ends.

Other types of solar eclipses:

  1. Partial Solar Eclipse
  • This happens when the sun, moon and Earth are not exactly lined up.
  • The sun appears to have a dark shadow on only a small part of its surface.
  1. Annular Solar Eclipse
  • An annular eclipse happens when the moon is farthest from Earth. Because the moon is farther away from Earth, it seems smaller. It does not block the entire view of the sun. The moon in front of the sun looks like a dark disk on top of a larger sun-coloured disk. This creates what looks like a ring around the moon.
  • During a solar eclipse, the moon casts two shadows on Earth. The first shadow is called the Umbra. This shadow gets smaller as it reaches Earth. It is the dark centre of the moon’s shadow.
  • The second shadow is called the Penumbra. The penumbra gets larger as it reaches Earth. People standing in the penumbra will see a partial eclipse. People standing in the umbra will see a total eclipse.

Why don’t solar eclipses happen at every New Moon?

  • The reason is that the Moon’s orbit tilts 5° to Earth’s orbit around the Sun.
  • Astronomers call the two intersections of these paths nodes.
  • Eclipses only occur when the Sun lies at one node and the Moon is at its New (for solar eclipses) or Full (for lunar eclipses) phase.
  • During most (lunar) months, the Sun lies either above or below one of the nodes, and no eclipse happens.

PYQ:

Historical and Archaeological Findings in News

Ikshvaku Period Lead Coins unearthed in Phanigiri

Why in the news?

  • Telangana’s Department of Heritage has recently unearthed a lead coin hoard belonging to Ikshvaku Period at Phanigiri, a renowned Buddhist heritage site.
  • The coins numbering 3,730 bore an elephant symbol on the obverse and a Ujjain symbol on the reverse.

Who were the Ikshvaku (225-340 A.D)?

  1. Origin and Rule
  • The Ikshvaku dynasty was a feudatory under the patronage of the Satavahanas.
  • Their capital was located at Vijayapuri, modern-day Nagarjunakonda in Andhra Pradesh.
  • They ruled over the delta of the Krishna and Godavari rivers on the east coast of the Andhra region.
  • They claimed to be descendants of the legendary king Ikshvaku, mentioned in ancient Sanskrit texts such as the Rigveda and Ramayana.
  • The dynasty’s founder was Vasishthiputra Chamtamula, who rose to power after the decline of the Satavahana dynasty.
  1. Cultural Affiliations
  • The Ikshvakus were Shaivites and performed Vedic rites, but they also patronized Buddhism, which flourished during their reign.
  • Under the reign of Vasishthi-putra Ehuvala Chamtamula, the Ikshvaku kingdom reached its zenith, marked by the construction of numerous Hindu and Buddhist shrines.
  • Their inscriptions and coins have been discovered at various archaeological sites, including Nagarjunakonda, Jaggayyapeta, Kottampalugu, Gurazala, Rentala, and Uppugunduru.
  1. Decline:
  • Successive rulers, such as Mathari-putra Vira-purusha-datta, Vasishthi-putra Ehuvala Chamtamula, and Vasishthi-putra Rudra-purusha-datta, contributed to the expansion and governance of the kingdom.
  • By the mid-4th century, the Pallavas had gained control of the former Ikshvaku territory, marking the decline of the dynasty.

About Phanigiri

  • Phanigiri village derived its name from the shape of the hillock, which appears to be like a snake hood.
  • The word Phani in Sanskrit means snake and Giri means hillock.
  • Studies suggest that the village had a vibrant life from 1000 BC to 18th century AD.
  • Phanigiri is believed to be one of the important Buddhist monasteries strategically located on the hilltop, on the ancient trade route (Dakshinapatha) connecting the west and the east coast of the Deccan.
  • Various stages of earlier excavations here discovered Mahastupa, apsidal Chaityagrihas, Votive stupas, pillared congregation halls, Viharas, platforms with staircases at various levels, octagonal stupa chaitya, 24-pillared mandapam, circular Chaitya.

Modern Indian History-Events and Personalities

Mangal Pandey: A Revolutionary Icon of Indian Independence

Why in the news?

It was on April 8th 167 years ago in 1857, Mangal Pandey was hanged.

Who was Mangal Pandey?

  • Mangal Pandey, born on July 19, 1827, in Nagwa village of the Ballia district in present-day Uttar Pradesh.
  • He belonged to the kingdom of Awadh, which had been treacherously annexed by the British in 1856.
  • At the age of 22, he enlisted as a soldier in the British East India Company’s army, joining the 34th Bengal Native Infantry.

Recap of his revolutionary activities

  1. Annexation of Awadh
  • The Begums of Awadh had an understanding with the British, and had been abiding by the terms of the agreement.
  • In spite of this, Awadh was annexed, in February 1856, which was greatly resented by the people.
  • Awadh was a region that supplied large numbers of soldiers of war to the Company’s army.
  • There were 75,000 soldiers from Awadh, and almost every agricultural family in the kingdom had a representative in the army.
  • Whatever happened in Awadh was of immediate concern to the Sepoy.
  1. Rise of Resentment
  • The deposition of the Nawab and the confiscation of the villages of taluqdars during the land revenue settlement of 1856 caused outrage.
  • Some 14,000 petitions were received from the Sepoys about the hardships they faced on account of the revenue system.
  • Mangal Pandey represented the discontent that the misery of British rule had brought upon peasant families.
  1. Flashpoint and the mutiny
  • Mangal Pandey was stationed at Barrackpore, near Calcutta (now Kolkata), where he became involved in a significant event that would later be known as the Sepoy Mutiny of 1857.
  • He refused to use the newly introduced Enfield rifle, the cartridges of which had a covering that was believed to be made of animal fat (beef and pork), and which had to be bit open before the cartridges could be used.
  • This was viewed by the soldiers as a direct assault on their religious beliefs by the British who intended to bring an end to their religion and propagate Christianity.
  • On March 29, 1857, Pandey mutinied and fired at his Senior Sergeant Major.
  • He was overpowered and hanged on April 8, 1857, by the order of a Court Martial at Lal Bagan in Barrackpore.
  • His regiment was disbanded, like the 19th infantry at Behrampore, for showing resentment.

PYQ:

[2019] The 1857 Uprising was the culmination of the recurrent big and small local rebellions that had occurred in the preceding hundred years of British Rule. Elucidate.

RBI to launch Mobile App for Retail Direct scheme

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Retail Direct Scheme

Mains level: NA

Why in the news?

The RBI has decided to introduce a Mobile App of its RBI Retail Direct scheme aimed at facilitating seamless investment in government securities by retail investors.

What is Retail Direct Scheme?

  • Retail Direct Scheme was rolled out in November 2021, giving access to individual investors to maintain gilt accounts with RBI and invest in government securities.
  • Using this app, investors can buy central and state government bonds as well as Treasury bills.
  • It enables investors to buy securities in primary auctions as well as buy/sell securities through the Negotiated Dealing System-Order Matching system (NDS-OM) platform.
  • A Gilt Account can be compared with a bank account, except that the account is debited or credited with treasury bills or government securities instead of money.

Treasury Bills:

  • They are promissory notes issued by the RBI on behalf of the government as a short term liability and sold to banks and to the public.
  • The maturity period ranges from 14 to 364 days.
  • They are the negotiable instruments, i.e. they are freely transferable.
  • No interest is paid on such bills but they are issued at a discount on their face value.

 How does it work?

  • Under the scheme, small investors can buy or sell government securities (G-Secs), or bonds, directly without an intermediary like a mutual fund.
  • However, the same tax rules apply to income from G-Secs.
  • The minimum amount for a bid is ₹10,000 and in multiples of ₹10,000 thereafter.
  • Payments may be made through Net banking or the UPI

Benefits of RDS

  • With the government being the borrower, there is a sovereign guarantee for the funds and hence zero risk of default.
  • Also, government securities may offer better interest rates than bank fixed deposits, depending on prevailing interest rate trends.

How can individuals access G-Sec offerings?

  • Investors wishing to open a Retail Direct Gilt account directly with the RBI can do so through an online portal set up for the purpose of the scheme.
  • Once the account is activated with the aid of a password sent to the user’s mobile phone, investors will be permitted to buy securities either in the primary market or in the secondary market.

PYQ:

[2018] Consider the following statements:

1. The Reserve Bank of India manages and services Government of India Securities but not any State Government Securities.

2. Treasury bills are issued by the Government of India and there are no treasury bills issued by the State Governments.

Banking Sector Reforms

What is Basel III Endgame?

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Basel Norms, Endgame

Mains level: NA

Why in the news?

The US Federal Reserve recently announced stricter bank capital requirements known as the “Basel III endgame” proposal.

What is Bank Capital?

  • Bank capital is a measure of bank shareholders’ investment in the business.
  • In contrast to deposits or money a bank has borrowed, capital does not have to be paid back.
  • In other words, it is a cushion or buffer that protects a bank from insolvency—and, thus, reduces the risk that a bank failure triggers system-wide financial instability.
  • A bank that has sufficient capital can cover customers’ deposits even if the loans it has made aren’t repaid or if its investments drop in value.

What are Basel Norms?

  • Basel, Switzerland, hosts the Bureau of International Settlement (BIS), fostering collaboration among central banks to establish global banking standards.
  • The Basel Committee on Banking Supervision (BCBS), established in 1974 formulates broad supervisory guidelines known as the Basel framework.
  • Its purpose is to ensure banks maintain adequate capital to meet obligations and absorb losses.
  • India has adopted Basel standards to align its banking practices with global norms.
Description
Basel I
  • Introduced in 1988.
  • Known as the Basel Capital Accord.
  • Focused on credit risk.
  • Set a minimum capital requirement of 8% of risk-weighted assets (RWA).
  • Assets were assigned risk weights based on their risk profile.
  • Adopted by India in 1999.
Basel II
  • Published in June 2004.
  • Aimed to refine and reform Basel I.
  • Introduced three pillars:
  1. Capital Adequacy Requirements
  2. Supervisory Review
  3. Market Discipline
  • Increased focus on risk management and disclosure.
  • Yet to be fully implemented in India and abroad.
Basel III
  • Released in 2010 after the 2008 financial crisis.
  • Aimed to strengthen the banking system.
  • Made banking activities more capital-intensive.
  • Focus on four key parameters:
  1. Capital
  2. Leverage
  3. Funding
  4. Liquidity
  • Designed to promote a more resilient banking system.
*Basel IV

 

  • In 2017, the Basel Committee agreed on changes to the global capital requirements as part of finalising Basel III.
  • The changes are so comprehensive that they are increasingly seen as an entirely new framework, commonly referred to as “Basel IV”.
  • Set to take effect under transition rules from 2025.*

 

Proposed Changes under Basel III Endgame

  • Expansion of Scope: The proposal aims to extend the strictest risk-based capital approach to more banks, lowering the asset threshold from $700 billion to $100 billion. This would encompass around 37 large banks in the U.S.
  • Standardized Measure for Capital Requirements: Regulators propose curtailing banks’ use of internal models to calculate capital requirements for loans, advocating for a standardized measure for all banks to ensure uniform risk assessment.
  • Increased Capital for Trading and Operational Risks: The proposal mandates higher capital reserves for risks linked to trading activities and operational challenges, requiring banks to utilize standard models for risk assessment instead of internal ones.
  • Changes to Capital Calculations for Portfolios: Banks with assets exceeding $100 billion must reflect gains and losses in portfolios categorized as “available for sale” in their capital calculations, aiming for a more precise depiction of a bank’s risk exposure.

Challenges created by the new Norms

  • Operational Risks: A substantial portion of the proposed capital increment targets banks’ operational risks, encompassing potential losses arising from internal processes, people, systems, or external events.
  • Non-Traditional Banking Activities: Entities engaged in trading, market-making, wealth management, and investment banking, will face more pronounced capital requirements due to altered risk assessment and operational risk calculations.
  • Industry-specific Concerns: Additionally, specific industries, like renewable energy, anticipate repercussions, fearing that increased capital requirements could undermine the effectiveness of tax incentives for projects targeting climate change.

Arguments in Favor of Increasing Capital

  • Financial Stability: Proponents argue that heightened capital requirements are imperative for safeguarding financial stability, averting bank failures, and minimizing the need for government bailouts.
  • Prudent Banking Practices: They contend that current standards inadequately address bank risks and that increased capital incentivizes prudent banking practices.
  • Resilient Banking System: Economists suggests that the social costs of higher capital requirements are minimal compared to the benefits of a more resilient financial system.

PYQ:

2015:

‘Basel III Accord’ or simply ‘Basel III’, often seen in the news, seeks to:

(a) Develop national strategies for the conservation and sustainable use of biological diversity

(b) Improve banking sector’s ability to deal with financial and economic stress and improve risk management

(c) Reduce the greenhouse gas emissions but places a heavier burden on developed countries

(d) Transfer technology from developed countries to poor countries to enable them to replace the use of chlorofluorocarbons in refrigeration with harmless chemicals

 

Practice MCQ:

What is the primary objective of “Basel III Endgame” in the banking sector?

(a) To encourage speculative investments by banks to boost short-term profits.

(b) To ensure the stability of the global financial system by strengthening the regulation, supervision, and risk management practices of banks.

(c) To encourage banks to invest more in less-risky assets to stimulate economic growth.

(d) To limit the role of central banks in regulating commercial banks and promote market-driven banking practices.

NexCAR19: India’s First Indigenous CAR T- Cell Therapy for Cancer

Note4Students

From UPSC perspective, the following things are important :

Prelims level: CAR-T Cell Therapy, NexCAR19

Mains level: NA

Why in the news?

  • President Droupadi Murmu has unveiled ‘NexCAR19’ India’s first indigenously-developed CAR T-cell therapy for cancer treatment.

What is CAR-T Cell Therapy?

What is it?
  • CAR-T cell therapy stands for Chimeric Antigen Receptor T cell therapy.
  • It is a type of cancer immunotherapy that uses the patient’s own T cells, genetically modified in a laboratory to enhance their ability to locate and destroy cancer cells.
How does it work?
  • T cells are white blood cells responsible for identifying and fighting illness and infection.
  • Each T cell has a receptor that can recognize antigens (proteins or molecules recognized by the immune system).
  • Cancer cells may have antigens that the immune system does not recognize as abnormal, allowing cancer to evade the immune response.
  • CAR-T cells are genetically engineered in the lab to express a new receptor that can bind to cancer cells and effectively kill them.
Therapy Process The process involves several steps, including:

1. Collecting T Cells: Blood is drawn from the patient’s arm, and T cells are separated from the blood using an apheresis machine.

2. Engineering T Cells: In a laboratory, the T cells are modified by adding a manufactured CAR, and they are allowed to multiply and grow.

3. Infusing CAR-T Cells: Once enough CAR-T cells are prepared, they are injected back into the patient’s arm.

  • Chemotherapy may be recommended before CAR-T cell infusion to enhance treatment effectiveness.
  • The process can take place in an outpatient infusion center or a hospital setting.
Cancers Treated
  • CAR-T cell therapy is effective against certain types of cancer, especially when other treatments are ineffective.
  • It is currently FDA-approved for treating haematological malignancies, including leukemia, lymphoma, and multiple myeloma.

 

NexCAR19: India’s Indigenously Developed CAR-T Therapy

  • NexCAR19 is designed to target cancer cells carrying the CD19 protein, a marker on cancer cells, enhancing precision in treatment.
  • It has been developed jointly by IIT Bombay and the Tata Memorial Centre.
  • Initially approved for patients aged 15 and above with B-cell lymphomas who did not respond to standard treatments, leading to relapse or recurrence.

Effectiveness and Unique Features

  • Approximately 70% of patients respond to NexCAR19 treatment, with some achieving complete remission.
  • Lab and animal studies indicate lower drug-related toxicities, including reduced neurotoxicity and Cytokine Release Syndrome (CRS).
  • Trials for paediatric patients are underway at Tata Memorial Hospital, ensuring broader applicability.

Availability and Affordability

  • ImmunoACT is in the process of securing licenses and partnering with hospitals, including Tata Memorial, Nanavati, Fortis, and Jaslok, across multiple cities.
  • Initially priced at Rs 30-40 lakh, ImmunoACT aims to eventually reduce the cost to Rs 10-20 lakh, making the therapy more accessible.

Taiwan’s Earthquake and the Pacific Ring of Fire

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Pacific ‘Ring of Fire’

Mains level: NA

Why in the news?

  • Taiwan was struck by its most powerful earthquake in at least 25 years.
  • Its susceptibility to earthquakes is attributed to its location along the Pacific “Ring of Fire” where a majority of the world’s seismic activity occurs.
  • Taiwan is primarily influenced by the collision of the Philippine Sea Plate and the Eurasian Plate.

What is the Pacific ‘Ring of Fire’?

  • The Pacific ‘Ring of Fire’ or Pacific Rim, or the Circum-Pacific Belt, is an area along the Pacific Ocean that is characterized by active volcanoes and frequent earthquakes.
  • Volcanic arcs and oceanic trenches partly encircling the Pacific Basin form the so-called Ring of Fire.
  • It is home to about 75 per cent of the world’s volcanoes – more than 450 volcanoes.
  • Also, about 90 per cent of the world’s earthquakes occur here.

Its spread

  • Its length is over 40,000 kilometres and traces from New Zealand clockwise in an almost circular arc covering Tonga, Kermadec Islands, Indonesia.
  • It is moving up to the Philippines, Japan, and stretching eastward to the Aleutian Islands, then southward along the western coast of North America and South America.

Seismic activity of the region

  • The area is along several tectonic plates including the Pacific plate, Philippine Plate, Juan de Fuca plate, Cocos plate, Nazca plate, and North American plate.
  • The movement of these plates or tectonic activity makes the area witness abundant earthquakes and tsunamis every year.
  • Along much of the Ring, tectonic plates move towards each other creating subduction zones.
  • One plate gets pushed down or is subducted by the other plate.
  • This is a very slow process – a movement of just one or two inches per year.
  • As this subduction happens, rocks melt, become magma and move to Earth’s surface and cause volcanic activity.
