Kodo millet is a staple food for many tribal and economically weaker sections in India. It is one of the 'hardiest crops, drought tolerant with high yield potential and excellent storage properties,' according to researchers

Background on Kodo Millet:

• Kodo millet (Paspalum scrobiculatum), also known as Kodra or Varagu, is a hardy, drought-tolerant crop widely grown in India, especially in Madhya Pradesh.
• It is a staple food for many tribal and economically weaker sections of India and is used to make various dishes like idli, dosa, and rotis.
• Kodo millet is valued for its high yield, nutritional benefits (rich in vitamins, minerals, antioxidants), and storage properties.

Incident in Bandhavgarh Tiger Reserve:

• 10 elephants from a herd of 13 died over three days in Madhya Pradesh’s Bandhavgarh Tiger Reserve.
• The cause of death was suspected to be mycotoxins associated with kodo millet, particularly Cyclopiazonic Acid (CPA), which is toxic to animals.

Historical Cases of Kodo Poisoning:

• The first human cases of kodo poisoning were reported in 1922 in the Indian Medical Gazette.
• Animals, including elephants, have also been affected by kodo millet consumption, with documented deaths as early as 1983.
• Cyclopiazonic Acid (CPA), a mycotoxin, was identified as the cause of kodo poisoning in the 1980s.

Why Does Kodo Millet Become Poisonous?

• Kodo millet is grown in dry and semi-arid regions and is vulnerable to fungal infections, particularly Ergot fungus, which produces CPA.
• When the crop encounters rainfall during maturing and harvesting, fungal infection can lead to "poisoned kodo," known locally as 'Matawna Kodoo' or 'Matona Kodo'.
• The mycotoxins in the infected millet are stable and resistant to standard food processing techniques.

Impact of Mycotoxins on Animals:

• Symptoms of poisoning: Vomiting, giddiness, unconsciousness, rapid pulse, cold extremities, limb tremors.
• Nervous and cardiovascular systems are primarily affected, causing liver dysfunction, heart damage, and gastrointestinal issues.
• In severe cases, consumption of infected kodo millet can cause death due to cardiovascular collapse and organ failure.
• Similar symptoms of depression and loss of mobility were observed in animal studies, including in mice.

Solution to Kodo Toxicity:

• Biocontrol agents (organisms that fight harmful pathogens) can help reduce fungal growth and mycotoxin production in kodo millet.
• Good agricultural practices: Sorting, proper storage in airtight containers, and avoiding moisture exposure during threshing can minimize contamination.
• Post-harvest management: Removing infected grains is crucial to preventing the spread of the disease.

Detection of Mycotoxins in Kodo Millet:

• Challenges: Mycotoxins are often undetectable by sight, and traditional methods like chromatography are time-consuming.
• Rapid detection tools: Enzyme-linked immunosorbent assays (ELISA), lateral flow assays (LFAs), and biosensors offer faster, on-site methods for detecting mycotoxins in kodo millet.

Centre for Science and Environment release a report on Extended Producer Responsibility (EPR) for Plastic Packaging

Key Findings:

• EPR Guidelines (2022) were a step towards enforcing the "polluter pays" principle, but the system faces significant issues in its implementation and registration processes.
• Centre for Science and Environment (CSE) report, released on October 29, 2024, highlights gaps in the EPR system for plastic packaging and suggests corrective actions.

EPR Guidelines Overview:

• Issued by: Union Ministry of Environment, Forest and Climate Change (MoEFCC).
• Objective: Hold producers, importers, brand owners (PIBOs), and plastic waste processors (PWPs) responsible for managing plastic packaging waste.
• Key Requirements:
  • PIBOs must register on a centralized portal and set targets for collection, recycling, and reuse of plastic packaging.
  • Registration involves compliance with targets on end-of-life recycling and recycled content usage.

Problems Identified in the Current EPR System:

• Low Registration and Enrollment:
  • 41,577 registrations on the EPR portal, but a significant discrepancy in the type of stakeholders registered.
  • 83% of registered entities are importers, 11% are producers, and only 6% are brand owners.
  • Producers contribute 65% of the plastic packaging in the market but have low registration.
• Absence of Key Polluters:
  • Manufacturers of virgin plastics are notably absent from the portal, despite being required to register.
• Fraudulent Practices:
  • 700,000 fake certificates were generated by plastic recyclers, far exceeding the actual certificate generation capacity.
  • The Central Pollution Control Board (CPCB) found that such fraudulent activities are undermining the integrity of the system.
  • For example, end-of-life co-processing units (e.g., cement plants) claimed to have processed 335.4 million tonnes per annum of plastic waste, while their actual capacity is just 11.4 million tonnes per annum.
• Underreporting and Mismanagement:
  • Despite 23.9 million tonnes of plastic packaging being introduced into the market, the CPCB’s estimation of plastic waste generation (4.1 MT annually) is underestimated.
• Lack of Stakeholder Representation:
  • Urban local bodies and informal waste collectors—key contributors to plastic waste management—are not included in the EPR framework, which limits their incentives and support.

Recommendations for Improvement:

• Incorporate the Informal Sector:
  • Recognize informal waste collectors and waste management agencies in the EPR framework to improve traceability and ensure better waste management.
• Eliminate Fraudulent Practices:
  • Strict actions need to be taken against fraudulent recyclers and fake certificate issuers to restore credibility to the EPR system.
• Establish Fair Pricing for EPR Certificates:
  • Undertake baseline cost studies to determine the true costs of plastic waste management, ensuring fair pricing for recycling certificates and preventing undervaluation.
• Standardize Packaging:
  • Focus on product standardization to ensure that packaging materials are uniform and easily recyclable.
• Strengthen Monitoring:
  • Improve oversight on the registration process and ensure that all polluters (producers, importers, brand owners) comply with the system’s guidelines.

EPR and Plastic Waste Management: Context and Importance

• Extended Producer Responsibility (EPR) is a policy approach where the responsibility of managing the entire lifecycle of plastic products (from production to disposal) lies with the producer.
• It is an essential part of India’s Plastic Waste Management Rules (2016), which mandate the recycling and proper disposal of plastic packaging waste.

Key Elements of EPR:

• Producer Accountability: Producers are responsible for the take-back, recycling, and final disposal of plastic packaging.
• Waste Minimization: Encourages reducing waste at the source by promoting sustainable packaging designs.
• Lifecycle Approach: Considers the entire lifecycle of the product, focusing on sustainability from production to disposal.
• Polluter Pays Principle: Ensures that the cost of waste management is borne by those responsible for generating the waste.

Scientists have discovered a "black hole triple" system, which is a rare configuration in space involving one black hole and two stars.

Overview of the Discovery:

• Location: The system is located 8,000 light years away from Earth, in the constellation Cygnus.
• Key Features:
  • A black hole at the center, currently consuming a star that is spiraling very close to it.
  • A second, more distant star that orbits the black hole every 70,000 years, and another star that orbits it every 6.5 days.

What is a Black Hole Triple System?

• Black Hole and Two Stars: Unlike typical binary systems (comprising a black hole and one other object), this system contains a black hole surrounded by two stars, one nearby and one far away.
• V404 Cygni: The central black hole in the system is the V404 Cygni, one of the oldest known black holes, roughly 9 times the mass of the Sun.

Significance of the Discovery:

• Questions on Black Hole Formation: The discovery raises new questions about how black holes are formed. Traditionally, black holes are thought to form after the explosion of a massive star (supernova), but this system does not follow that model.
• New Formation Theory: Researchers suggest the black hole may have formed via a "direct collapse" process, where a star collapses into a black hole without undergoing a supernova explosion. This is referred to as a "failed supernova".
  • In a failed supernova, the star's collapse happens too quickly for the explosive outer layers to be ejected, leading to the formation of a black hole without the typical violent explosion.

Implications for Other Binary Systems:

• The black hole’s gradual consumption of one of its stars may imply that some binary black hole systems could have originally been triple systems, with one star eventually being consumed by the black hole.

Research and Collaboration:

• Study: The discovery was made by researchers at California Institute of Technology (Caltech) and Massachusetts Institute of Technology (MIT).
• Published in: The findings were published in Nature in October 2024.

Additional Context:

• Distance: The system is about 8,000 light years away, which is vast but still observable with advanced telescopes.
• Mystery of the "Failed Supernova": The concept of a failed supernova offers new insights into the life cycle of massive stars and their transformation into black holes.

In News:

• Odisha government relocated a tigress from Maharashtra’s Tadoba-Andhari Tiger Reserve to Similipal Tiger Reserve, Odisha, to address inbreeding issues among the tiger population.
• The tigress is part of a genetic diversification plan to remedy the increasing number of pseudo-melanistic tigers in the region.

Pseudo-melanistic Tigers:

• Pseudo-melanistic tigers, often referred to as "black tigers," exhibit a darker coat with broader, more prominent stripes.
• The mutation leads to the appearance of a mostly black fur, with occasional white-orange stripes.

Genetic Basis:

• This coloration is due to a mutation in the Taqpep gene, which causes the widening and darkening of stripes on the tiger's coat.
• The mutation is linked to genetic drift and inbreeding within the isolated Similipal population.

Historical Context:

• These tigers were once considered mythical until the 1700s, with sightings only being documented in the 1990s and 2017-18.
• The first confirmed genetic evidence of the black tiger appeared when a cub was born in captivity at Oklahoma City Zoo in the 1970s.

Distribution and Prevalence:

• Pseudo-melanistic tigers are predominantly found in Similipal Tiger Reserve, with 27 out of 30 tigers in Odisha exhibiting the trait.
• Other instances of such tigers exist in captivity, such as in Nandankanan Zoological Park (Bhubaneswar) and Arignar Anna Zoological Park (Chennai), both tracing ancestry to Similipal.

Genetic Studies:

• A 2021 study by the National Centre for Biological Sciences (NCBS) linked the Taqpep gene mutation to the unique appearance of these tigers.
• The mutation causes a missense change in the gene, replacing Cytosine with Thymine (C1360T), altering the tiger’s coat pattern.

High Frequency of Mutation in Similipal:

• Genetic analyses indicate a high frequency of the Taqpep gene mutation in Similipal tigers, with a 60% chance that a tiger born there will carry the mutated gene.
• Inbreeding and genetic isolation have contributed to this phenomenon, as Similipal’s tiger population is geographically cut off from other populations.

Prime Minister Narendra Modi has expanded the Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (PM-JAY) to provide health coverage to citizens aged 70 years and above, regardless of their income or economic status. This move is aimed at addressing the healthcare challenges faced by India's elderly population, which has been growing rapidly.

Key Highlights of the Ayushman Bharat Expansion:

• Health Coverage for Elderly:
  • Ayushman Vaya Vandana Card: This new health card offers Rs 5 lakh annually for individuals aged 70 and above. The coverage is shared within the family, so if there are multiple elderly beneficiaries in one household, the total cover will be split.
  • Scope: This initiative is designed to provide a safety net for elderly people, many of whom had previously been unable to access treatment due to high costs.
• Significance of the Scheme:
  • India’s elderly population is rapidly growing, with the number of people over 60 expected to reach 319 million by 2050, up from 103 million in 2011.
  • The expansion of PM-JAY to include those aged 70+ is a critical step in making universal health coverage more inclusive as India’s population ages.
• Eligibility and Registration:
  • Individuals aged 70 years and above must register on the PM-JAY portal or through the Ayushman app. Those who already have an Ayushman Bharat card must complete an eKYC process to receive the new card and coverage.
  • Exclusions: The scheme is not available in Delhi and West Bengal, as these states have not adopted the Ayushman Bharat scheme.
• Financial Details:
  • The initial outlay for this expansion will be Rs 3,437 crore, covering the remainder of the current financial year and the next year.
  • Cover for Overlapping Health Schemes: Elderly individuals who are already covered under other government schemes (e.g., CGHS, Ex-Servicemen Contributory Health Scheme) will have the option to either continue with their current coverage or choose Ayushman Bharat. Those with ESIC or private insurance can access both Ayushman Bharat and their existing cover.
• Coverage Scope:
  • The expansion is expected to benefit approximately 6 crore individuals across 4.5 crore families.
  • Existing Coverage: Around 1.78 crore elderly people are already covered under the scheme. Additional coverage will be provided to those not currently included in the scheme.
• Interoperability with Other Schemes:
  • Those under the Central Government Health Scheme (CGHS), Ex-Servicemen Contributory Health Scheme (ECHS), or other similar schemes will need to choose between their current insurance and the Ayushman Bharat scheme.
  • However, individuals enrolled in Employees' State Insurance Corporation (ESIC) can have both their existing cover and the Ayushman Bharat coverage.
• Rollout and Reach:
  • The scheme will be implemented across 33 states and Union Territories, except Delhi, Odisha, and West Bengal.
  • Over 29,600 hospitals, including more than 12,600 private facilities, are empanelled to provide treatment under PM-JAY.

Other Key Announcements:

• U-WIN Portal: A pan-India digital platform for routine vaccinations, aimed at enhancing the efficiency of vaccination programs.
• Critical Care Facilities: The Prime Minister also launched critical care infrastructure, including new facilities in AIIMS Bhubaneswar, Kalyani, and super-specialty units in Himachal Pradesh and Madhya Pradesh.

LiDAR (Light Detection and Ranging) is a cutting-edge remote sensing technology that uses laser pulses to measure distances and create detailed 3D maps of Earth's surface. This technology has recently played a crucial role in discovering a lost Mayan city hidden under the dense Mexican jungle.

What is LiDAR?

• Definition: LiDAR is a remote sensing technology that uses pulsed laser light to measure distances and generate precise 3D models of Earth’s surface.
• Components: The system includes a laser, a scanner, and a GPS receiver. It is usually mounted on an aircraft to map large areas of terrain.
• Data Accuracy: LiDAR can create high-resolution 3D models with vertical accuracy up to 10 cm, making it highly precise for mapping ground elevation.

How LiDAR Works

• Laser Emission: LiDAR sends out rapid laser pulses toward the ground.
• Reflection: These pulses hit the Earth’s surface, reflecting off features like vegetation, buildings, and terrain.
• Measurement: The time it takes for the laser light to travel to the ground and back is measured, allowing the system to calculate the distance between the sensor and the surface.
• Point Cloud Data: The reflected light data is collected as a "point cloud", representing all the surfaces it hits, including trees, buildings, and other features.
• Refinement: This point cloud can be processed into a Digital Elevation Model (DEM), stripping away vegetation and structures to reveal the “bare earth,” which highlights features like roads, buildings, and hidden settlements.

Why LiDAR is Useful for Archaeologists

• Large-Scale Surveying: Traditional archaeological methods often involve labor-intensive fieldwork, such as walking over every square meter and manually cutting through thick vegetation. LiDAR, however, allows researchers to quickly survey vast areas of land, even through dense jungle, from the comfort of a lab.
• Visibility Under Vegetation: LiDAR’s ability to penetrate dense foliage and reveal features beneath the surface is a game changer. Even thick tree canopies that obscure the ground are no match for the laser pulses, which can pass through gaps to illuminate hidden structures.

The Discovery of the Lost Mayan City

• The City of Valeriana: Using publicly available LiDAR data from a forest monitoring project in 2013, archaeologist Luke Auld-Thomas discovered a lost Mayan city in Mexico’s Campeche region. The city, named Valeriana, had been hidden for centuries by the thick jungle.
• City Features: The city has all the hallmarks of a Classic Maya political capital, including:
  • Multiple enclosed plazas
  • Broad causeways
  • Temple pyramids
  • A ball court
  • A reservoir formed by damming a seasonal watercourse
• Historical Significance: Valeriana is believed to date back before 150 CE and may have been a key political and cultural center in the Maya civilization.

Applications of LiDAR Beyond Archaeology

• National Platform for the Rights of the Disabled (NPRD) has called for a rollback of the new rules, citing that they make the process of obtaining disability certificates more stringent and cumbersome.

Key Changes Under the New RPwD Rules, 2024

• Authority for Issuing Disability Certificates:
  • Only a designated medical authority or a notified competent medical authority at the district level can issue disability certificates.
  • NPRD had proposed that experts from non-profits also be authorized to carry out checks, but this suggestion was not accepted.
• Colour-Coded UDID Cards:
  • The new rules introduce colour-coded UDID cards to represent levels of disability:
    • White (general disability)
    • Yellow (moderate disability)
    • Blue (severe disability with 80% or higher).
• Mandatory Online Applications:
  • Applicants are now required to apply for disability certificates online, which could be problematic for individuals who lack access to the internet, smartphones, or are digitally illiterate.
  • The NPRD has urged the government to retain the option for in-person applications.
• Extended Time for Certificate Issuance:
  • The new rules extend the time for issuing disability certificates from one month to three months.

According to the WMO, the last time the earth had a similar CO2 concentration was 3-5 million years ago, when temperatures were 2-3°C higher and sea levels were 10-20 metres higher than they are now

Key Highlights:

• Record High Greenhouse Gas (GHG) Levels:
  • In 2023, annual mean carbon dioxide (CO2) levels rose by 2.3 parts per million (ppm), reaching a new record of 420 ppm.
  • This marks the 12th consecutive year with an increase of over 2 ppm in CO2 levels.
• Historical Context:
  • CO2 levels not seen in 3-5 million years, when temperatures were 2-3°C higher, and sea levels were 10-20 meters higher than they are today.
• Key GHGs at Record Highs:
  • The globally averaged surface concentrations of CO2, methane, and nitrous oxide all reached new highs in 2023.
• Contributors to the Increase in CO2:
  • Natural Variability: Natural factors such as large vegetation fires and reduced carbon absorption by forests contributed to higher CO2 levels.
  • Human Activity: High fossil fuel emissions from human and industrial activities also played a major role.
  • El Niño Phenomenon: The El Niño event led to higher temperatures and drier conditions, exacerbating the rise in GHG levels through increased wildfires and reduced carbon absorption by land sinks.
• Climate Feedback Loop Concerns:
  • The WMO warned of a vicious cycle:
    • Climate change could cause ecosystems to become larger sources of GHGs.
    • Wildfires could release more carbon, and warmer oceans may absorb less CO2, leading to more CO2 remaining in the atmosphere, accelerating global warming.
• Radiative Forcing:
  • Radiative forcing (the warming effect on climate) from long-lived GHGs has increased by 51.5% from 1990 to 2023, with CO2 contributing 81% of this increase.
• Methane Concerns:
  • Methane saw its largest three-year increase between 2020 and 2022.
  • This increase was linked to warmer temperatures and wetter land conditions during the 2020-2022 La Niña conditions, which caused an uptick in methane emissions from natural wetlands.
• Long-Term Impact of CO2:
  • Given CO2's long atmospheric lifetime, even with rapid emissions reductions, the warming effect will persist for several decades.

The United Nations Environment Programme (UNEP) recently published the Emissions Gap Report 2024, in anticipation of the COP29 meeting of the UNFCCC to be held in Baku, Azerbaijan.

Key Highlights:

• Current Trajectory of Global Warming:
  • If countries continue with current environmental policies, global temperatures are expected to rise by 3.1°C above pre-industrial levels.
  • This is significantly higher than the Paris Agreement target of limiting global warming to well below 2°C, with an effort to cap it at 1.5°C.
• Paris Agreement at Risk:
  • Even if all Nationally Determined Contributions (NDCs) are fully implemented (including both unconditional and conditional emissions reduction targets), the world would still experience 2.6°C of warming by 2030.
  • This presents a major challenge to achieving the Paris Agreement’s climate goals.
• Urgent Need for Action:
  • To limit global warming to 1.5°C, greenhouse gas emissions must peak before 2025 and decline by 43% by 2030.
  • The report highlights the emission gap between current pledges and what is required to meet the 1.5°C goal.
• Record High Emissions:
  • Global greenhouse gas emissions hit a record 57.1 gigatons of CO? equivalent in 2023.
  • This represents an increase of 1.3% compared to 2022, continuing the upward trend from the previous decade.
• India’s Emissions:
  • India’s greenhouse gas emissions grew by 6.1% between 2022 and 2023.

Marine and Terrestrial Conservation:

• Marine Areas: Need for greater investment in marine conservation, as India's marine protected areas (MPAs) are limited.
• Protected Areas: While 7.5% of India’s terrestrial area is protected, significant threats like climate change and habitat fragmentation persist.

Biodiversity and Climate Change:

• Climate Change Risks: Impacts on vulnerable ecosystems, including coral reefs and alpine regions, further threaten biodiversity.
• Population Growth: India’s rapidly growing population (one of the highest in the world) places constant pressure on natural resources and ecosystems.

Illegal Wildlife Trade:

• Global Ranking: India is the fourth-largest illegal wildlife trader globally, with an annual trade worth approximately £15 billion.
• Call for Action: Stronger enforcement of wildlife protection laws and international cooperation are crucial to combat illegal wildlife trade.

SDGs and India’s Conservation Challenges:

• SDG 14 (Life Below Water) and SDG 15 (Life on Land): India faces significant challenges in meeting these Sustainable Development Goals, particularly in protecting marine life and terrestrial ecosystems.

Recommendations for Improvement:

• Stronger Political Will: Political commitment is essential for passing laws that promote sustainable development and biodiversity conservation.
• Enforcement and Funding: Increased funding for environmental initiatives and better enforcement of conservation policies are necessary to address the conservation challenges.
• Sustainable Development: Integrating sustainable land use practices and improving governance structures for conservation are key areas for focus.
