  • PM-Kisan Samman Nidhi Yojana

    Why in the News?

    The Prime Minister will release the 17th installment of the Pradhan Mantri Kisan Samman Nidhi (PM-KISAN), amounting to over ₹20,000 crore, for 92.6 million beneficiary farmers across the country.

    About the PM-KISAN Scheme

    • The PM-KISAN is a Central Sector Scheme with 100% funding from the Government of India.
    • It is being implemented by the Ministry of Agriculture and Farmer’s Welfare.
    • Launched: In February 2019.
    • Aim: To help procure various inputs to ensure proper crop health and appropriate yields, commensurate with the anticipated farm income at the end of each crop cycle.
    • Objective: To provide eligible farmers with an annual financial assistance of ₹6,000.
      • This assistance is distributed in three equal instalments of ₹2,000 each every 4 months, via Direct Benefit Transfer (DBT) into beneficiaries’ bank accounts.
    • Beneficiaries:
      • Farmer families that hold cultivable land can apply for the benefits of this plan.
      • Small and Marginal Farmers (SMFs) (a farmer who owns cultivable land up to 2 hectare as per land records of the concerned State/UT.).
      • The entire responsibility of identification of beneficiary farmer families rests with the State / UT Governments.

    Do you know?

    The PM-KISAN scheme was first conceived and implemented by the government of Telangana as the Rythu Bandhu scheme.

    Rythu Bandhu Scheme

    • It is also known as the Farmer’s Investment Support Scheme (FISS).
    • It is a welfare programme for farmers started in 2018 by the Telangana government.
    • Under the scheme, the state government provided the 58 lakh farmers in Telangana with ₹5,000 per acre of their land as a farm investment for two crops.
    • There is no ceiling on the number of acres held by a farmer.
    • So, a farmer who owns two acres of land would receive Rs 20,000 a year, whereas a farmer who owns 10 acres would receive Rs 1 lakh a year from the government.
    • This investment is made twice a year, once for the kharif harvest and once for the Rabi harvest.
    • It is the country’s first direct farmer investment support scheme where cash is paid directly to the beneficiary.

    Impact of the Scheme

    • Beneficiaries outreach: Over 11 crore farmers (with more than 3 crore women farmers) across the country have availed of the PM-Kisan scheme, indicating its widespread reach and impact.
    • Financial Support: This financial aid helps farmers meet their agricultural expenses, purchase seeds, fertilizers, and other inputs, and support their families’ livelihoods.
    • Improved Agricultural Practices: This contributes to food security and boosts the agricultural sector’s growth.
    • Poverty Alleviation: The scheme plays a crucial role in alleviating poverty among small and marginal farmers by providing them with a steady source of income just like Universal Basic Income (UBI).
    • Enhanced Livelihoods: PM-Kisan supports farmers’ livelihoods, by providing a safety net during times of agricultural distress or economic uncertainties, ensuring a better quality of life for rural communities.

  • What is an Electromagnet?

    PC: The Hindu

    Why in the News?

    Recently Scientists have designed a magnetic resonance imaging (MRI) scanner that costs a fraction of existing machines, setting the stage for improving access to this widely used diagnostic tool. So we need to know about the Electromagnet.

    What is an Electromagnet?

    • Invented in 1824 by William Sturgeon, electromagnets revolutionised technology.
    • Sturgeon was an English physicist and inventor who discovered that wrapping a coil of wire around a piece of iron and passing an electric current through the wire produced a magnetic field.
    • Electromagnets are used in Loudspeakers for sound reproduction, Motors for mechanical movement., and MRI machines for medical imaging, etc

    How Electromagnets Work?

    • Electric current flowing through a wire generates a magnetic field around the wire.
    • Coiling the wire enhances this magnetic field by concentrating it within the coil’s core.
    • This configuration creates an electromagnet, where the strength of the magnetic field is directly proportional to the current flowing through the coil.
    • The magnetic flux density so generated is measured in ‘Tesla’.

    Enhancing Magnetic Strength with a Core

    • Coiling the wire around a magnetic material (core), such as iron or steel:
      • Amplifies the magnetic field produced by the electric current.
      • Ferromagnetic materials like iron align their internal magnetic domains with the external magnetic field generated by the coil.
      • This alignment significantly increases the overall magnetic strength of the electromagnet compared to a non-magnetic core.

    Persistence of Magnetization

    • It refers to the property of a material to retain a certain amount of magnetization even after the removal of an external magnetic field.
    • Certain core materials exhibit retained magnetization even after the current ceases.
    • This residual magnetism is useful in applications requiring sustained magnetic fields, such as:
      • Superconducting electromagnets used in MRI machines, are capable of producing magnetic fields up to 30 Tesla.
      • Research electromagnets like those used in particle physics, which require stable and powerful magnetic fields.

    Who was Michael Faraday (1791-1867)?

    • Michael Faraday was a pioneering English scientist and physicist who made substantial contributions to the fields of electromagnetism and electrochemistry.
    • Faraday is best known for his experiments and discoveries in electromagnetism, which laid the groundwork for the principles of electromagnetic induction and the laws of electrolysis.

    Key achievements of Michael Faraday include:

    1. Electromagnetic Induction: He discovered electromagnetic induction in 1831, showing that a changing magnetic field induces an electric current in a nearby conductor.
    2. Electrochemistry: Faraday formulated the laws of electrolysis, which describe the quantitative relationship between the amount of material produced or consumed during electrolysis and the amount of electricity passed through the electrolyte.
    3. Faraday’s Laws of Electromagnetic Induction: These laws describe the fundamental principles of generating electricity using magnetic fields, forming the basis for the development of electric generators and transformers.
    4. Faraday Cage: He invented the Faraday cage, a device used to block electromagnetic fields.

  • No outcome in Bonn: why money is key to climate action

    Why in the news?

    The Bonn climate meeting failed to define a new climate finance goal, crucial for finalizing a sum exceeding $100 billion annually by the end of 2024.

    Key Highlights of the Climate Meeting in Bonn, Germany

    • Failure to Define New Climate Finance Goal: The recent climate meeting in Bonn did not make significant progress in setting a new climate finance goal. This new goal is supposed to replace the existing $100 billion per year target, which needs to be finalized by the end of 2024.
    • Outcome: The meeting only produced a lengthy 35-page “input paper” summarizing various countries’ demands and concerns, without providing any concrete numbers or agreements. This paper is expected to be developed into a formal negotiating draft for COP29 in Baku, Azerbaijan.

    Search for a New NCQG (New Collective Quantified Goal)

    • Importance of Climate Finance: Money is essential for climate action, including mitigation, adaptation, and other tasks like collecting and reporting climate data, which require substantial funds, especially in developing countries.
    • Existing Commitment: Developed countries had promised to mobilize $100 billion annually from 2020 to help developing countries fight climate change. This target is now being re-evaluated to increase the amount post-2025.

    Previous Assessment

    • Current Needs: It is widely recognized that developing countries now require trillions of dollars annually. A UNFCCC assessment indicated that these countries need about $6 trillion by 2030 for climate actions, with adaptation needs alone requiring $215 billion to $387 billion annually.
    • Energy Transition: The global shift to clean energy requires investments of about $4.3 trillion per year until 2030 and around $5 trillion annually thereafter until 2050 to achieve global net-zero emissions.
    • Developing Countries’ Demands: India has proposed that developed countries should provide at least $1 trillion annually after 2025, while Arab and African countries have suggested figures of $1.1 trillion and $1.3 trillion, respectively.

    Debate Over Contribution

    • Original Responsibility: According to the UNFCCC and Paris Agreement, only the 25 countries listed in Annexure 2, along with the European Economic Community, are responsible for providing climate finance to developing countries.
    • Shifting Responsibility: These countries argue that other nations, such as China, Gulf countries, and South Korea, are now economically capable and should also contribute. However, countries like China have stated they do not intend to take on additional responsibilities beyond their current efforts.
    • Developed Countries’ Stance: While acknowledging that the new target must be higher than the existing $100 billion per year, developed countries have not made any specific offers publicly.

    Way forward:

    • Clear Definition of Climate Finance: Establish a universally accepted definition of climate finance to prevent discrepancies in reporting and ensure transparency.
    • Precise Targets and Timelines: Set clear, incremental targets leading up to the final goal, with defined timelines for achieving these targets. This will provide a roadmap for both developed and developing countries.

  • Longitude Prize on Antimicrobial Resistance (AMR)

    Why in the News?

    Sysmex Astrego, a Sweden-based diagnostic company, won the £10 million Longitude Prize for developing a high-tech UTI (Urinary Tract Infection) test called the PA-100 AST System. 

    What is Antimicrobial Resistance?

    • Antimicrobial Resistance (AMR) occurs when bacteria, viruses, fungi, and parasites change so that medicines no longer work against them.
    • This makes infections harder to treat and can lead to more severe illness and even death.
    • AMR can occur naturally through genetic changes or when one type of microorganism picks up resistance from another.
    • It can also occur randomly due to mutations or when resistant genes spread between different organisms.
    • The main reasons for AMR are antibiotics incorrectly or too often, not having access to clean water and good hygiene, not doing enough to prevent infections, and people not knowing how to use antibiotics properly.

    Global Impact of AMR

    • Global Threat: Antibiotic-resistant infections caused nearly 1.3 million deaths in 2019, with projections to exceed cancer-related deaths by 2050.
    • Economic Impact: The global economy faces potential losses of up to 4 trillion by 2030 and 100 trillion by 2050 due to the AMR crisis.

    About the Longitude Prize

    • The Longitude Prize, valued at £8 million (₹85 crore), was recently awarded for its profound implications in combating antimicrobial resistance (AMR).
    • The prize launched in 2014, aims to revolutionize infection management globally.
    • Historical Context:  
      • Origins: Established in 1714 to solve the maritime longitude problem, demonstrating the critical need for accurate navigation.
      • Modern Application: The 21st-century Longitude Prize addresses pressing global challenges like AMR, incentivizing innovative solutions.
    • Goal of the Prize:
      •  Aims to replace current lab-based diagnostic methods with rapid tests that guide targeted antibiotic therapies, combating AMR effectively.

    About PA-100 AST System 

    • Technology Breakthrough: Developed by Sysmex Astrego, this system uses a phenotypic test that identifies UTI bacteria and performs antibiotic susceptibility testing in under 45 minutes.
    • Operation: A single-use cartridge processes less than half a milliliter of urine, using microfluidic traps and phase-contrast imaging in a shoe box-sized reader instrument.
    • Clinical Impact: Provides rapid “sensitive” or “resistant” results for antibiotics, aiding doctors in immediate, accurate treatment decisions at the point of care.

    Current Challenges in UTI Diagnosis

    • Limited Accuracy: Current options include urine dipstick tests for quick results but limited accuracy (50-60%) and lab cultures with 2-3 day turnaround times.
    • Impact on Treatment: Delayed diagnosis often leads to empirical antibiotic use, contributing to antibiotic resistance worldwide.

    Significance for India

    • Healthcare Burden: In India, millions seek treatment for UTIs annually, impacting lives and healthcare systems significantly.
    • Potential: Rapid, accurate point-of-care tests could revolutionize UTI management globally, saving lives and reducing healthcare costs.

  • Scientists back new Alzheimer’s drug: Benefits vs Risks

    Why in the News?

    Donanemab, a new Alzheimer’s disease therapy developed by Eli Lilly, has gained unanimous support from independent scientists advising the US Food and Drug Administration (FDA), moving it closer to clinical use.

    What is Donanemab?

    • Donanemab is a monoclonal antibody, which means it is a laboratory-produced molecule designed to function like antibodies in the immune system.
    • It is specifically developed for individuals in the early stages of Alzheimer’s disease, including those with mild cognitive impairment or mild dementia.

    How Does Donanemab Work?

    • It targets amyloid beta proteins in the brain. Amyloid beta plaques are one of the defining features of Alzheimer’s disease.
    • Mechanism of Action: The drug binds to amyloid beta plaques and promotes their removal from the brain. This action is intended to slow down the progression of Alzheimer’s disease by reducing the accumulation of these toxic plaques.

    How do the benefits of the drug stack up against its risks?

    • Target Population: The drug is intended for those in the early stages of Alzheimer’s disease (mild cognitive impairment or mild dementia).
    • Benefits: Significant clinically meaningful slowing of the disease, allowing patients to retain their functions for a longer time. Phase 3 study shows a 35.1% slowdown in cognitive decline in early Alzheimer’s patients over 76 weeks.
    • Risks: Main adverse effects include brain swelling (24%) and brain bleeds (19.7%), with most cases being asymptomatic.Three treatment-related deaths reported.Amyloid-related imaging abnormalities (ARIA) like brain bleeds and seizures were mostly non-serious and resolved after discontinuation of therapy.
    • Risk Management: The key risks can be mitigated through appropriate labeling and clinical monitoring. Further risks will be characterized through post-authorization studies.

    Why is a breakthrough of this kind important?

    • Rising Burden of Alzheimer’s: The global population is ageing, leading to an increased burden of diseases like Alzheimer’s. In India, 5.3 million people are currently living with dementia, expected to rise to 14 million by 2050.
    • Lack of Effective Treatments: There are limited options for disease-modifying treatments for Alzheimer’s. Innovations like donanemab are crucial for providing new hope and potential therapies.
    • Economic Considerations: While the drug is expensive, it offers the potential for several more years of quality life for patients.

    Why was the approval for the drug delayed?

    • Additional Data Requirements: The USFDA wanted to understand further the data relating to the therapy, especially regarding the limited dosing protocol used during trials.
    • Limited Dosing Protocol: During the trial, therapy was stopped in patients who achieved a certain level of amyloid beta plaque clearance, which is a distinguishing feature of donanemab compared to other therapies.
    • Previous Drug Approval Irregularities: Scrutiny increased after irregularities were found in the approval process of the first drug, aducanumab, which involved close collaboration between the regulator and the drugmaker and approval despite negative trial outcomes. The second drug, lecanemab, also had cautious optimism from doctors due to its demonstrated efficacy with fewer side effects.

    Conclusion: Ensure rigorous and transparent review processes for new Alzheimer’s treatments, incorporating comprehensive data analysis and post-authorization studies to monitor long-term safety and efficacy.

  • Why heatwaves have not been included as a notified disaster in the Disaster Management Act?

    Why in the news?

    The current period of intense heat in several regions has once more sparked debates about the potential inclusion of heatwaves as officially recognized disasters under the Disaster Management (DM) Act of 2005.

    What are Notified Disasters?

    • According to the Disaster Management (DM) Act, 2005, a disaster is defined as a “catastrophe, mishap, calamity, or grave occurrence” arising from natural or man-made causes that result in substantial loss of life, destruction of property, or environmental damage and is beyond the coping capacity of the affected community.
    • Funds: The DM Act allows states to draw money from the National Disaster Response Fund (NDRF) and the State Disaster Response Fund (SDRF) for managing these disasters.
    • Current Notified Disasters: There are currently 12 categories of notified disasters: cyclones, drought, earthquake, fire, flood, tsunamis, hailstorms, landslides, avalanches, cloudbursts, pest attacks, and frost and cold waves.

    Why Heatwaves Were Not Included as Notified Disasters?

    • Common Occurrence: Heatwaves were historically considered regular events during summer months in many parts of India. They were not seen as exceptional or unusual disasters warranting specific disaster management provisions under the DM Act, 2005.
    • Perception of Predictability: Unlike sudden-onset disasters such as earthquakes or cyclones, heatwaves were perceived as relatively predictable and part of seasonal weather patterns. This perception led to a belief that they could be managed through general public awareness and local interventions rather than formal disaster response mechanisms.
    • Not fit in definition of Disaster: When the DM Act was formulated, disasters were defined as events that caused substantial loss of life, property, or environmental damage beyond the coping capacity of the affected community. At that time, the impacts of heatwaves were typically viewed as localized health issues rather than widespread disasters.
    • Lack of Urgency: There was a lack of urgency in recognizing heatwaves as disasters requiring national-level response frameworks. The focus of disaster management efforts initially leaned towards more acute and visible calamities like cyclones, floods, and earthquakes.

    Why is the Centre Not Adding Heatwaves as a Notified Disaster Now?

    • Financial Concerns: One of the primary concerns is the potential financial burden of declaring heat waves as a notified disaster. Under the current provisions, the government is obligated to provide monetary compensation for lives lost during notified disasters, which is set at Rs 4 lakh per victim.
    • The reluctance of Finance Commissions: Despite requests from various states, the 15th Finance Commission has not recommended adding heatwaves to the list of notified disasters. They argue that the existing categories adequately cover disaster response needs, and they have provided provisions for states to utilize a portion of the State Disaster Response Fund (SDRF) for local disasters like heatwaves.

    Conclusion: Engage with the Finance Commission and other relevant bodies to reassess the inclusion of heatwaves as a notified disaster. Highlight the evolving nature of heat waves, their increasing frequency, and the need for dedicated funding and support mechanisms.

    Crater Names and Significance

    • Lal Crater: Named after Prof. Devendra Lal, former director of PRL, this 65 km wide crater is positioned at -20.98° and 209.34°.
    • Mursan Crater: Named after a town in Uttar Pradesh, India, this ~10 km wide crater is situated on the eastern side of the Lal crater’s rim.
    • Hilsa Crater: Named after a town in Bihar, India, this ~10 km wide crater is positioned on the western side of the Lal crater’s rim.

    Scientific Importance of Lal Crater

    • Lava Coverage: The entire Lal crater area, located in the Tharsis volcanic region on Mars, is covered with lava.
    • Evidence of Water: Geophysical evidence, including a 45-meter thick sedimentary deposit, suggests the presence of water in the subsurface of the Lal crater. This finding supports the theory that Mars once had water flowing on its surface.
    • Infilling Process: Mursan and Hilsa craters, positioned on either side of the Lal crater, offer insights into the infilling process of the Lal crater. Their presence indicates that infilling occurred episodically over time.
