  • Alzheimer’s Research: Mystery of Brain Cell Death

    brain cell

    Central Idea

    • Scientists have long sought medical treatments for Alzheimer’s disease but have faced limited success.
    • The approval of the drug Lecanemab by the US FDA in 2023 has brought renewed optimism, as it shows promise in slowing the progression of Alzheimer’s in its early stages.

    How brain cells die?

    • Revealing the Connection: Researchers from Belgium and UK have shed light on the connection between abnormal proteins (amyloid and tau) and a process called necroptosis, which leads to cell death.
    • Cell Death Mechanism: Necroptosis is a form of cell death typically triggered by immune responses to infection or inflammation, serving to eliminate damaged cells.
    • Inflammatory Response: The study suggests that in Alzheimer’s patients, amyloid protein entering brain neurons triggers inflammation and alters the internal chemistry of the cells. Amyloid forms plaques, while tau forms tangles.
    • MEG3 Molecule: When amyloid and tau processes occur simultaneously, brain cells produce a molecule called MEG3, which appears to be linked to cell death.
    • Blocking MEG3: The researchers experimented by blocking the MEG3 molecule and found that brain cells survived when this molecule was inhibited.
    • Experimental Approach: Human brain cells were transplanted into genetically modified mice that produced significant amyloid, allowing researchers to make these groundbreaking observations.

    Hope for Alzheimer’s Treatment

    • Historic Discovery: Researchers highlighted that this discovery marks the first time, after several decades of speculation, that scientists have found a plausible explanation for cell death in Alzheimer’s patients.
    • Path to New Medicines: Some are optimistic that their findings will pave the way for new medical treatments targeting Alzheimer’s.
    • Lecanemab’s Target: Lecanemab, a drug that specifically targets the amyloid protein, aligns with the potential to block the MEG3 molecule, offering the prospect of halting brain cell death in Alzheimer’s disease.

    Understanding Brain’s Complex Processes

    • Brain’s Enigma: The development of Alzheimer’s drugs has been hampered by a lack of understanding of the disease’s mechanisms within the brain.
    • Amyloid and Tau: Amyloid and tau proteins are known to accumulate in the brain of Alzheimer’s patients, but their precise roles and how they contribute to cell death remained unclear.

    Alzheimer’s Global Challenge

    • Widespread Impact: Approximately 55 million people worldwide are affected by various forms of dementia, with Alzheimer’s being one of the prominent diseases.
    • Disproportionate Burden: Two-thirds of dementia cases are found in developing countries, and with the aging global population, projections indicate that the number of dementia cases could reach 139 million by 2050, with China, India, Latin America, and Sub-Saharan Africa facing the greatest challenges.

  • AFSPA Extension in Manipur: A Delicate Balancing Act

    afspa manipur

    Central Idea

    • The Manipur government has announced the extension of the Armed Forces (Special Powers) Act (AFSPA) for another 6 months across the entire state.
    • However, it excludes 19 police stations in seven districts of the Imphal Valley.

    Why such move?

    • Gradual Withdrawal: Since 2022, AFSPA has been progressively withdrawn from the valley districts, primarily inhabited by the Meitei community.
    • Resurgence of Insurgent Groups: There has been a resurgence of insurgent groups, largely operating from Myanmar, advocating for Manipur’s secession from India.
    • Ethnic Violence: Ethnic violence between the Meitei and tribal Kuki communities has claimed at least 175 lives since May 3, making it the deadliest conflict in Manipur since 1999.

    AFSPA History in Manipur

    • Decades of AFSPA: AFSPA has been applicable in Manipur since 1981, impacting both the valley and hill districts.
    • Gradual Withdrawal: The Act’s provisions have been gradually withdrawn from the valley districts over the years, signifying evolving security dynamics.

    What is Armed Forces (Special Powers) Act, 1958?

    • Armed Forces Special Powers Act, to put it simply, gives armed forces the power to maintain public order in “disturbed areas.”
    • AFSPA gives armed forces the authority use force or even open fire after giving due warning if they feel a person is in contravention of the law.
    • The Act further provides that if “reasonable suspicion exists”, the armed forces can also arrest a person without a warrant; enter or search premises without a warrant; and ban the possession of firearms.

    A Backgrounder

    • The AFSPA, 1958 came into force in the context of insurgency in the North-eastern States decades ago.
    • It provides “special power” to the Armed Forces applies to the Army, the Air Force and the Central Paramilitary forces etc.
    • It has been long contested debate whether the “special powers” granted under AFSPA gives total immunity to the armed forces for any action taken by them.

    What are the Special Powers?

    • Power to use force: including opening fire, even to the extent of causing death if prohibitory orders banning assembly of five or more persons or carrying arms and weapons, etc are in force in the disturbed area;
    • Power to destroy structures: used as hide-outs, training camps, or as a place from which attacks are or likely to be launched, etc;
    • Power to arrest: without warrant and to use force for the purpose;
    • Power to enter and search premises: without a warrant to make arrest or recovery of hostages, arms and ammunition and stolen property etc.

    Who can declare/notify such areas?

    • The Central Government or the Governor of the State or administrator of the Union Territory can declare the whole or part of the State or Union Territory as a disturbed area.

  • India to unveil 50-year Government Bonds

    Central Idea

    • India is set to make history by issuing it’s first-ever 50-year government bonds and 30-year green bonds.
    • These offerings have piqued the interest of insurance companies and provident funds seeking avenues to invest their long-term funds.

    Why such move?

    • Ambitious Target: India aims to mobilize â‚č6.55 trillion ($78.73 billion) through bond sales from October to March. This includes a significant â‚č300 billion allocation to the 50-year security, marking the central government’s maiden auction of such bonds.
    • Natural Demand: Long-term investors, particularly insurers, find the 50-year bonds appealing due to their alignment with asset-liability management requirements.

    Government Bonds in India

    • Government Bonds in India, fall under the broad category of Government Securities (G-Sec) and are primarily long term investment tools issued for periods ranging from 5 to 40 years.
    • It can be issued by both Central and State governments of India. Government bonds issued by State Governments are also called State Development Loans (SDLs).
    • The GB interest rates, also called a coupon, can either be fixed or floating and disbursed on a semi-annual basis.
    • In most cases, GOI issues bonds at a fixed coupon rate in the market.

    Types:

    Fixed-Rate Bonds Offer a fixed interest rate throughout the investment tenure, providing clarity with the coupon rate mentioned.
    Floating Rate Bonds (FRBs) Subject to periodic interest rate adjustments, often with a base rate and fixed spread determined through auctions.
    Sovereign Gold Bonds (SGBs) Allow investments in gold without physical possession, with tax-exempt interest and prices linked to gold’s value.
    Inflation-Indexed Bonds Adjust both principal and interest based on inflation, using indices like CPI or WPI, tailored for retail investors.
    7.75% GOI Savings Bond Features a 7.75% interest rate and available to individuals, minors with legal guardians, and Hindu Undivided Families.
    Bonds with Call/Put Option Permit either issuer or investor to buy back or sell bonds, respectively, on specified dates, after 5 years from issuance.
    Zero-Coupon Bonds Generate earnings from the difference between issuance and redemption prices, as they do not provide interest income.

    Advantages offered

    • Sovereign Guarantee: Government bonds are backed by the government’s commitment, offering stability and assured returns.
    • Inflation-Adjusted: Inflation-indexed bonds protect investors from rising prices, maintaining the real value of their investments.
    • Regular Income: Government bonds provide semi-annual interest disbursements, offering investors a source of regular income.

    Limitations

    • Lower Income: Apart from 7.75% GOI Savings Bonds, government bonds typically offer lower interest rates.
    • Lack of Relevance: With maturity tenures ranging from 5 to 40 years, government bonds may lose relevance over time, particularly in the face of inflation.

  • AFSPA likely to end from Assam

    afspa

    Central Idea: Assam CM has stated that the Armed Forces Special Powers Act (AFSPA) is likely to be completely lifted from the state by the end of the year due to a significant improvement in the law and order situation.

    What is Armed Forces (Special Powers) Act, 1958?

    • Armed Forces Special Powers Act, to put it simply, gives armed forces the power to maintain public order in “disturbed areas.”
    • AFSPA gives armed forces the authority use force or even open fire after giving due warning if they feel a person is in contravention of the law.
    • The Act further provides that if “reasonable suspicion exists”, the armed forces can also arrest a person without a warrant; enter or search premises without a warrant; and ban the possession of firearms.

    A Backgrounder

    • The AFSPA, 1958 came into force in the context of insurgency in the North-eastern States decades ago.
    • It provides “special power” to the Armed Forces applies to the Army, the Air Force and the Central Paramilitary forces etc.
    • It has been long contested debate whether the “special powers” granted under AFSPA gives total immunity to the armed forces for any action taken by them.

    What are the Special Powers?

    • Power to use force: including opening fire, even to the extent of causing death if prohibitory orders banning assembly of five or more persons or carrying arms and weapons, etc are in force in the disturbed area;
    • Power to destroy structures: used as hide-outs, training camps, or as a place from which attacks are or likely to be launched, etc;
    • Power to arrest: without warrant and to use force for the purpose;
    • Power to enter and search premises: without a warrant to make arrest or recovery of hostages, arms and ammunition and stolen property etc.

    Who can declare/notify such areas?

    • The Central Government or the Governor of the State or administrator of the Union Territory can declare the whole or part of the State or Union Territory as a disturbed area.

    Issues with AFSPA

    • Power to kill: Section 4 of the Act granted officers the authority to “take any action” even to the extent to cause the death.
    • Misconduct by Armed Forces: The issue of violation of human rights by actions of armed forces came under the consideration of the Committee on Amendments to Criminal Law (popularly known as Justice Verma Committee) set up in 2012. It observed that- in conflict zones, legal protection for women was neglected.
    • Autocracy: The reality is that there is no evidence of any action being taken against any officer of the armed forces or paramilitary forces for their excesses.

    Recommendations to repeal AFSPA

    • Justice B.P. Jeevan Reddy Commission: The 2004 Committee headed by Justice B.P. Jeevan Reddy, the content of which has never officially been revealed by the Government, recommended that AFSPA be repealed.
    • ARC II: The Administrative Reforms Commission in its 5th Report on ‘Public Order’ had also recommended that AFSPA be repealed.

    Voices for repeal

    • Human rights violations: The repeal of AFSPA is necessary not just for restoring constitutional sanity, but also as a way of acknowledging the dark history of our conduct in Nagaland.
    • Need for ensuring individual dignity: The political incorporation of Nagaland (and all other areas where this law applies) will be set back if the guarantees of the individual dignity of the Indian Constitution are not extended.
    • Not state of exception: We often describe AFSPA in terms of a “state of exception”. But this theoretical term is misleading. How can a law that has been in virtually continuous existence since 1958 be described as an “exception”.
    • Lack of human empathy: At the heart of AFSPA is a profound mutilation of human empathy.

    Conclusion

    • To bring in lasting peace in the North East, the government needs to avoid the trap of watered-down peace accords.
    • While the move to withdraw AFSPA is welcome, it needs to be gradually erased.
    • For that, changes in the ground situation would be crucial. Mere smoke signals or drum-beating can never do the job.

  • Centre seeks to ease Angel Tax Provisions

    Central Idea

    • The government has introduced revisions to the angel tax provisions that were initially implemented in this year’s Budget, primarily targeting investments by non-resident investors into startups at a premium over their fair market value.

    Key changes introduced

    • The Central Board of Direct Taxes issued a notification, amending Rule 11UA under the Income Tax Act, incorporating changes to the draft norms released earlier.
    • Five distinct valuation methods for shares have been introduced, accompanied by a 10% tolerance allowance for deviations from accepted share valuations.
    • These changes aim to provide some relief to prospective foreign investors interested in Indian startups.

     

    Angel Investment

    • An angel investor is an individual who provides financial backing to early-stage startups or entrepreneurs, typically in exchange for equity in the company.
    • Angel investors are typically high-net-worth individuals who invest their own personal funds, rather than investing on behalf of a firm or institution.
    • Features of Angel Investing:
    1. Early-stage funding
    2. Equity investment
    3. High-risk, high-reward
    4. Active involvement
    5. Personal investment
    6. Flexible terms
    7. Shorter investment horizon

     What is Angel Tax?

    • Referred to as Angel Tax, this rule is described in Section 56(2)(viib) of the Income Tax Act, 1961.
    • Essentially it’s a tax on capital receipts, unique to India in the global context.
    • This clause was inserted into the act in 2012 to prevent laundering of black money, round-tripping via investments with a large premium into unlisted companies.
    • The tax covers investment in any private business entity, but only in 2016 was it applied to startups.

    Why was angel tax introduced?

    • The complicated nature of VC fundraising with offshore entities, multiple limited partners and blind pools is contentious.
    • There has been some element of money laundering or round-tripping under guise.

    Details of its levy

    • The Angel Tax is being levied on startups at 9% on net investments in excess of the fair market value.
    • For angel investors, the amount of investment that exceeds the fair market value can be claimed for a 100% tax exemption.
    • However, the investor must have a net worth of â‚č2 crores or an income of more than â‚č25 Lakh in the past 3 fiscal years.

  • Challenge of Phosphorus Scarcity and Pollution: A Need for Innovative Solutions

    Central Idea

    • Phosphorus scarcity poses a growing challenge to global agriculture, with critical implications for food production and environmental sustainability.
    • While the history of land fertilization dates back to ancient agricultural practices, the advent of synthetic fertilizers in the 19th century transformed modern agriculture.
    • However, today’s reliance on synthetic fertilizers, particularly phosphorus, raises concerns about its scarcity and environmental impact.

    Age-Old Challenge of Soil Fertilization

    • Historical Origins: The challenge of fertilizing land dates back to the dawn of agriculture. Early human societies recognized the need to replenish soil nutrients depleted by repeated cycles of cultivation and harvest.
    • Ancient Fertilization: Indigenous communities worldwide devised fertilization techniques, including the use of fish remnants and bird droppings (guano), to restore essential nutrients to the soil.

    Revolutionizing Agriculture with Synthetic Fertilizers

    • 19th Century Advancements: The 19th century witnessed significant progress in chemistry, leading to the creation of synthetic fertilizers. It also marked the identification of key nutrients: nitrogen, phosphorus, and potassium, the foundation of modern chemical fertilizers.
    • Green Revolution’s Impact: The mid-20th-century Green Revolution accelerated the adoption of high-yield crop varieties and intensive fertilizer use, revolutionizing global food production.

    About Phosphorus

    Need Essential nutrient for plant growth, involved in photosynthesis, energy transfer, and root development.
    Impact of Deficiency Leads to stunted growth, reduced flowering, and poor fruit or seed development in plants.
    Types – Superphosphate

    – Triple Superphosphate (TSP)

    – Diammonium Phosphate (DAP)
    Application Applied through broadcasting, banding, or direct placement with seeds during planting.
    Benefits Promotes strong root development, better flowering, fruiting, and overall plant health.
    Environmental Considerations Efficient use is required to prevent runoff and environmental issues like eutrophication.
    Balanced Fertilization Maintain a nutrient balance (N-P-K) in soil to avoid both deficiency and excess of phosphorus.

    Phosphorus Predicament

    • Phosphorus Scarcity: Phosphorus is a finite resource primarily found in specific geological formations. It’s not only depleting but also causing environmental pollution when it enters water bodies, leading to algal blooms and eutrophication.

    Geopolitical Complexities

    • Global Phosphorus Reserves: Today, a small group of countries, including Morocco and the Western Sahara region, controls the majority of the world’s phosphorus reserves. This geopolitical control raises concerns.
    • Cadmium Contamination: Phosphorus often coexists with cadmium, a heavy metal harmful to health. Cadmium-laden fertilizers can contaminate crops, posing health risks.
    • Largest Importer: India is the world’s largest importer of phosphorus, primarily from cadmium-rich deposits in West Africa.
    • Cadmium Susceptibility: Staple crops like paddy in India are vulnerable to cadmium absorption, potentially causing health issues.

    Challenge of Phosphorus Disposal

    • Loss and Wastage: Only a fraction of mined phosphorus is consumed through food; a significant amount is lost to water bodies due to excessive fertilizer application.
    • Sewage Contamination: Most phosphorus consumed ends up in sewage. Inadequate sewage treatment allows phosphorus to accumulate in water bodies, fueling algal blooms and depleting oxygen.

    Exploring Phosphorus Alternatives

    • Precision Agriculture: Reducing chemical fertilizer use through precision agriculture offers one solution to address phosphorus scarcity without compromising yield.
    • Circular Water Economies: Urban sewage can become a valuable source of phosphorus. Two key strategies:
      1. Source Separation Toilets: Collect urine, a concentrated waste stream rich in phosphorus, and convert it into local fertilizer.
      2. Recycling Wastewater and Sludge: Recover nutrients, including phosphorus, from sewage sludge through innovative methods like sludge mining.

    Incentive Challenges

    • Overuse of Fertilizers: In rural India, powerful farmers often sell fertilizers, encouraging smaller farmers to overuse them. This requires better extension services and awareness campaigns.
    • Perceptions of Sewage: In urban India, sewage has historically been stigmatized, affecting regulations and wastewater treatment practices.

    Rethinking the Approach

    • Systemic Change: Fundamental changes are needed, including lowering sewage mining costs, allowing urban-mined phosphorus in agriculture, and shifting utility incentives from discharge standards to nutrient recovery.
    • Multi-Beneficial Solution: Such changes can tackle multiple challenges, including geopolitical dependency, affordable fertilizers, improved water bodies, and public health benefits.

    Conclusion

    • The phosphorus dilemma is a pressing challenge with far-reaching consequences for agriculture, geopolitics, and the environment.
    • As we grapple with dwindling phosphorus reserves and its environmental pollution, innovative solutions must be embraced.
    • Precision agriculture and circular water economies, including source-separating toilets and sewage recycling, offer promising avenues to alleviate the scarcity issue.
