  • Indian Astronomers discover new method for Solar Cycle Amplitude Prediction

    Why in the News?

    • Astronomers from the Indian Institute of Astrophysics (IIA) have developed a new method to predict the amplitude of the upcoming solar cycle.

    What is Space Weather?

    • Space weather refers to the varying conditions within the solar system and its heliosphere, influenced by the Sun and solar wind.
    • The main components of space weather include: solar wind, coronal mass ejections, and solar flares.
    • These components can compress the Earth’s magnetosphere, triggering geomagnetic storms.
    • This can disrupt communication, power transmission, damage spacecraft electronics, and pose threats to astronauts.

    Solar Cycle and Its Importance

    • The activity of the Sun follows an approximately 11-year periodic cycle, marked by variations in the number of sunspots on the Sun’s surface.
    • This solar cycle influences space weather, Earth’s atmosphere, and climate variations.
    • Predicting the amplitude of the solar cycle is a major challenge in astrophysics, as it directly affects related phenomena and space weather.

    Research Findings

    • IIA researchers discovered that the width of supergranular cells on the solar surface during the minimum year of the solar cycle is correlated with the number of sunspots observed during the subsequent solar cycle maximum.
    • This simple method can be used to predict the strength of the upcoming solar cycle, which is valuable for space weather forecasting.

    What are Supergranular Cells?

    • Supergranular Cells are large convective cells on the Sun’s surface, with diameters of about 30,000 km.
    • These cells are part of the solar convection zone where hot plasma rises, cools as it reaches the surface, and then sinks back down in a continuous cycle.
    • Characteristics:
      • Supergranular cells are larger than granules, another type of convective cell on the Sun. Its borders, known as supergranular lanes, are about 5,000 km thick.
      • Plasma within these cells moves from the center of the cell toward the edges, where it sinks back into the Sun’s interior. This movement creates a network of lanes that can be observed on the solar surface.
      • Supergranular cells are associated with the magnetic field concentrations on the Sun’s surface, often where sunspots and other magnetic features appear.

    PYQ:

    [2022] If a major solar storm (solar flare) reaches the Earth, which of the following are the possible effects on the Earth?

    1. GPS and navigation systems could fail.
    2. Tsunamis could occur at equatorial regions.
    3. Power grids could be damaged.
    4. Intense auroras could occur over much of the Earth.
    5. Forest fires could take place over much of the planet.
    6. Orbits of the satellites could be disturbed.
    7. Shortwave radio communication of the aircraft flying over pola-regions could be interrupted.

    Select the correct answer using the code given below:

  • What is the drug Captagon?

    Why in the News?

    Captagon, the “poor man’s cocaine,” has become increasingly popular among young adults in the Middle East and North Africa.

    What is the Drug Captagon?

    • Captagon is a synthetic drug that was originally developed in Germany in the 1960s and 1970s.
    • It was initially created as a pharmaceutical treatment for attention deficit disorders, narcolepsy, and sometimes depression.
    • The primary active ingredient in Captagon is fenethylline, a compound that, once ingested, is metabolized into two powerful stimulants: amphetamine and theophylline.
    • These substances stimulate the central nervous system, leading to increased alertness, reduced fatigue, and a sense of euphoria.

    How Addictive is Captagon?

    • Captagon is highly addictive due to its powerful effects on the brain and body.
    • As a psychostimulant, Captagon significantly impacts the central nervous system, leading to a range of effects that can make it very difficult for users to stop taking the drug once they start.
    • It is also reportedly used by fighters in conflict zones to enhance their endurance and suppress fatigue.
    • The primary effects of Captagon include:
    1. Euphoria: Users often experience an intense feeling of happiness or well-being.
    2. Increased Wakefulness: The drug reduces the need for sleep, keeping users awake and alert for extended periods.
    3. Enhanced Physical and Mental Performance: Users may feel stronger, more focused, and more capable of performing both physically and mentally demanding tasks.
    • However, the heavy use of Captagon comes with serious risks such as cognitive impairment, cardiovascular issues, and risk of addiction.

    Where is Captagon Made?

    • In recent years, Syria the “narco state” of Middle East has emerged as the largest producer of Captagon.
    • Its production increased after 2011 Arab Spring protests, which led to civil unrest and conflict in the region.

  • Extremophile bacteria have learnt to survive microwaves

    Why in the News?

    Researchers have isolated extremophile bacteria from harsh environments like volcanic vents, permafrost, acid mines, deep-sea hydrothermal vents, and lakes beneath polar ice caps.

    What are Extremophiles?

    • Extremophiles are microorganisms that thrive in extreme environmental conditions where other life forms typically cannot survive.
    • For example: Volcanic vents, Permafrost, Acid mines, Deep-sea hydrothermal vents, dark lakes buried beneath polar ice caps, on the exteriors of spacecraft, around nuclear waste storage sites.

    Adaptation and Evolution:

    • Extremophiles have developed unique biological and biochemical processes over millions of years to adapt to diverse habitats.
    • Unlike more complex life forms, which have one set of proteins, extremophiles have multiple sets of proteins, each adapted to specific environmental conditions.
    • These proteins are ‘activated’ based on the surrounding environment, enabling survival during extreme conditions like high temperatures, lack of water, or high acidity.
    • Significance: Some scientists believe that life on Earth may have begun as an extremophile in extreme environmental niches before spreading and adapting to more temperate ecosystems.

    About the ‘Earth Microbiome Project’

    • It is a global initiative aimed at mapping, organising, and understanding the diversity of microbial life across different environmental niches on Earth.
    • The project was founded in 2010.
    • Objective: 
      • To sequence 200,000 genetic samples from diverse environments.
      • To assemble 500,000 microbial genomes, creating a comprehensive map of microbial diversity on Earth.
    • Significance:
      • The project is part of broader efforts to understand the microbial world, which is still in its infancy.
      • It is related to other significant projects like the ‘Earth Biogenome Project,’ which aims to sequence the genomes of all eukaryotic organisms on the planet.
      • Understanding microbial diversity has numerous biological and industrial applications, such as developing new enzymes for molecular biology or finding new ways to adapt organisms to challenging environments.

     

    PYQ:

    [2017] With reference to agriculture in India, how can the technique of ‘genome sequencing’, often seen in the news, be used in the immediate future?

    1. Genome sequencing can be used to identify genetic markers for disease resistance and drought tolerance in various crop plants.

    2. This technique helps in reducing the time required to develop new varieties of crop plants.

    3. It can be used to decipher the host-pathogen relationships in crops.

  • WHO declares Mpox as Public Health Emergency of International Concern

    Why in the news?

    The World Health Organization (WHO) has declared mpox as a “public health emergency of international concern” (PHEIC).

    What is a PHEIC?

    • A PHEIC is a formal declaration by the WHO under the International Health Regulations (IHR), 2005.
    • It refers to an “extraordinary event” posing a public health risk through the international spread of disease, potentially requiring a coordinated global response.
    • Criteria for PHEIC:
      • Serious and unusual event: Poses a significant public health risk.
      • Cross-border implications: Affects more than one country.
      • International response needed: Requires immediate global coordination.
    • Purpose: Mobilizes resources, raises awareness, and coordinates efforts to manage and contain the threat.

    What is Mpox?

    • Mpox is a disease caused by the orthopoxvirus, related to the smallpox virus.
    • First detected in humans in 1970, it is endemic in central and West Africa.
    • Transmission: Spread from animals to humans (zoonotic) and between humans via close contact, respiratory droplets, or contaminated materials.
    • Symptoms: Fever, rash, swollen lymph nodes; can lead to severe complications or death.
    • Vaccination: WHO recommends vaccines, widely used in Nigeria and the Democratic Republic of the Congo (DRC) to control outbreaks.

    Recent Developments: 

    • In recent years, there has been an increase in mpox cases, including the emergence of new strains such as clade 1b, which has spread to countries outside of its typical endemic regions.
    • This led to the declaration of mpox as a Public Health Emergency of International Concern (PHEIC) due to its potential for widespread impact.

  • Does India have laws on the movement of ballast water?

    Why in the News?

    The TN Water Resources Department (WRD) has informed the National Green Tribunal that it has requested â‚č160 crore from Kamarajar Port in Ennore, Tamil Nadu, to address the removal of invasive mussels along the coast near the port.

    • The WRD has accused Kamarajar Port of being primarily responsible for the spread of this invasive species due to its failure to regulate ballast water from ships.

    What is Ballast Water?

    • Ballast water is fresh or saltwater held in the ballast tanks of ships. It is used to provide stability and maneuverability during a voyage, especially when a ship is not carrying enough cargo or when additional stability is required due to rough seas.
    • Ballast water can carry a variety of biological materials, including bacteria, microbes, and small invertebrates. When discharged at a new location, this water can introduce non-native species into local ecosystems, potentially leading to ecological imbalances.

    How Serious is the Problem?

    • Invasive Species in India: Scientists have recorded nearly 30 invasive species entering Indian waters through ship ballast water, with the charru mussel (Mytella strigata) being one of the most harmful. This species has replaced native species in critical habitats like Pulicat Lake in Tamil Nadu.
    • Ecological Impact: The introduction of invasive species can disrupt local ecosystems, outcompete native organisms, and significantly affect biodiversity. The charru mussel has a high survival rate and prolific reproduction, exacerbating its impact on marine environments.
    • Economic Consequences: The proliferation of invasive species can hinder fishing activities and affect the livelihoods of local communities dependent on marine resources.

    What are Global Regulations?

    • Ballast Water Management (BWM) Convention: The International Maritime Organization (IMO) adopted the BWM Convention, which came into force in 2017. This convention aims to prevent the spread of harmful aquatic organisms and pathogens through ballast water.
    • Under the BWM Convention, ships must manage their ballast water to ensure that aquatic organisms and pathogens are removed or rendered harmless before discharge.
    • Compliance: Countries like Australia and New Zealand have stringent regulations to prevent ballast water from damaging their marine ecosystems, including rigorous checks of ballast water management systems.

    What is India’s Position?

    • As of July 2023, India has not signed the BWM Convention, meaning there are no obligations for ships calling at Indian ports to comply with its regulations. This lack of participation raises concerns about the unchecked discharge of ballast water.
    • While other maritime regulations apply in Indian ports but the discharge of ballast water is not subject to checks or regulations, leading to potential ecological risks.

    Way forward: 

    • Adopt and Implement the BWM Convention: India should consider ratifying the Ballast Water Management (BWM) Convention to align with international standards.
    • Strengthen Domestic Regulations and Awareness: Even before ratifying the BWM Convention, India can introduce national legislation to regulate ballast water discharge in its ports.

  • Hints of the corporatization of science research in India 

    Why in the News?

    The establishment of the Anusandhan National Research Foundation and its funding structure clearly signals the government’s intended direction.

    Research Policy in India

    • Shift Towards Corporatisation: The Indian government’s approach encourages research institutions to generate revenue through external sources, moving away from reliance on public funding.
      • This trend aligns with the 2015 Dehradun Declaration, which advocated for marketing patents to self-finance research initiatives.
    • Focus on Market-Driven Research: The ANRF aims to align research outcomes with market needs, promoting the idea that scientific advancements should have immediate applications.
      • This is evident in the emphasis on prototype development, which assesses the marketability of research products, which was highlighted in the 2024 Budget speech.
    • Integration of Industry and Academia: The ANRF is designed to forge collaborations between research institutions and the private sector by earmarking a substantial portion of its funding (approximately 72%) from private sources, bridging the gap between scientific research and commercial application.
    Note: The Anusandhan National Research Foundation (ANRF) is a significant initiative in India’s research landscape, established under the Anusandhan National Research Foundation Act, 2023.

    Funding Mechanism of ANRF

    • Budget Allocation: The ANRF will be allocated â‚č50,000 crore over five years, with a significant portion expected to come from non-government sources, including industry and philanthropic contributions.
    • Governance Structure: The ANRF will be governed by a board that includes industry representatives and experts, ensuring that funding decisions align with market demands and technological advancements.

    What are the signals despite the stated objective of ANRF? (challenges)

    • Potential Undermining of Curiosity-Driven Research:  The private sector does not want to fund basic research because it has no immediate commercial applications which ultimately leads to a decline in foundational scientific exploration.
    • Public Funding Concerns: The government’s expectation for private sector funding raises questions about the sustainability of public investment in research.
      • The current ratio of public funding for science research in India (0.6% to 0.7% of GDP) is significantly lower than that of countries like South Korea (around 4.8%  of GDP).

    India’s Achievements Despite a Low GDP Investment in R&D: 

    • High Production of PhDs:  Annually, India generates approximately 40,813 PhDs, ranking third globally after the United States and China. 
    • Robust Research Output: India’s research output remains substantial, with over 300,000 publications in 2022, making it the third-largest producer of scientific publications globally.

    • Improvement in Global Rankings: India has made significant strides in global innovation rankings and research quality. It improved its position on the Global Innovation Index (GII) from 81st place in 2015 to 40th in 2023.  
        • India climbed to the 9th rank in the Nature Index 2023, surpassing countries like Australia and Switzerland.
    • Investment in Autonomous R&D Institutions: A considerable portion of India’s R&D funding is directed towards autonomous research laboratories. The total investment in R&D reached approximately $17.2 billion in 2020-21, with a significant allocation to key scientific agencies such as the Defence Research and Development Organisation (DRDO) and the Indian Council of Agricultural Research (ICAR).

    Comparison with Other Countries

    As of 2023, India’s gross expenditure on R&D stands at approximately 0.64% of its GDP.

    • United States: The U.S. invests about 3.46% of its GDP in R&D
    • South Korea: South Korea leads with an impressive 4.8% of GDP allocated to R&D.
    • Germany: Germany’s R&D spending is around 3.1% of GDP.
    • China: China’s investment in R&D is approximately 2.4% of GDP.
    • Taiwan: Taiwan also invests around 3.77% of its GDP in R&D.

    Way Forward: 

    • Strengthening Public Funding for Basic Research: To ensure a balanced research ecosystem, the government should increase public investment in foundational scientific research.
    • Enhancing Industry-Academia Collaboration: The government should facilitate stronger partnerships between research institutions and the private sector while maintaining a focus on both applied and basic research.
