  • Open access is crucial for self-reliance in science

    Why in the News?

    As per Nature Index” India’s scientific prowess is rising but lacks essential research infrastructure. Initiatives like I-STEM aim to bridge this gap by democratizing access to advanced facilities.

    The Indian Science Ecosystem:

    • Growth in Research: India ranks third globally in research output and eleventh in research quality according to the “Nature Index”.
    • Infrastructure Shortfalls: Despite an increase in the number of universities from 760 in 2014 to 1,113 in 2021, many lack essential resources such as advanced labs, instrumental access, and research literature.

    Why is the Open Access Crucial for Self-Reliance in Science?

    • Open Access (OA) ensures that scientific knowledge is freely available to all, regardless of geographical or financial barriers.
    • It promotes inclusivity and allows researchers from diverse backgrounds to access the latest research findings, fostering collaboration and innovation.

    Initiatives to Address Gaps:

    • I-STEM: Catalogues all publicly funded research facilities nationwide and makes them available to researchers based on need.
    • One Nation, One Subscription (ONOS): Proposes a centralized model of subscription to scientific journals to make them universally available to all publicly funded institutions, addressing the high cost of accessing commercial journals.

    What is the Optimal Solution?

    • The optimal solution lies in prioritizing Open Access (OA) initiatives. With a global shift towards OA and increasing mandates from major funding bodies, India should leverage this trend to reduce dependency on costly subscriptions and ensure widespread access to scientific literature.
      • Major funding bodies and countries are pushing for OA, with the U.S. mandating immediate open accessibility of publicly funded research by 2025.
    • Challenges with ONOS: The high cost and oligopolistic academic publishing market make negotiation difficult. OA reduces the necessity of a costly unified subscription. ONOS does not ensure long-term access or global accessibility of Indian research.
    • The Green Open Access: Green Open Access allows authors to deposit a version of their work in a university repository, making it freely accessible globally. Ensures long-term preservation and accessibility of research funded by taxpayer money.

    Limitations:

    • Indian funding agencies have mandated green OA, but it has not been enforced effectively.
    • Recent issues should catalyze a stronger push for green OA.

    Conclusion: India should enhance its journal system, avoiding payment burdens on authors or readers. Utilise digital technology capabilities to create and share low-cost, high-quality scientific publishing infrastructure for the global south.

    Mains PYQ:

    Q  India’s Traditional Knowledge Digital Library (TKDL) which has a database containing formatted information on more than 2 million medicinal formulations is proving a powerful weapon in the country’s fight against erroneous patents. Discuss the pro and cons of making the database available publicly available under open-source licensing. (UPSC IAS/2015)

  • Genetic Mysteries of Microcephaly: The Role of SASS6 Gene

    Why in the News?

    A gene called SASS6 (Spindle Assembly Abnormal Protein 6) and its variants have been found to play a key role in a developmental process that causes “Microcephaly”.

    What is Microcephaly?

    • Microcephaly is a condition where a baby’s head is much smaller than normal.
    • It is associated with a smaller brain, poor motor skills, poor speech, abnormal facial features, and intellectual disabilities.
    • Developmental Roots:
      • The condition is believed to start during the peak phase of brain development in the embryo. Cells that are supposed to become neurons fail to divide normally.
    • Diagnosis:
      • Microcephaly can be diagnosed before birth using foetal ultrasound and MRI.

    Role of SASS6 gene 

    • Since 2014, the SASS6 gene and its variants have been linked to microcephaly.

    A recent study in China:(On March 19, 2024)

    • The study of a consanguine couple revealed microcephaly and fetal growth issues. Confirming the SASS6 gene’s role in microcephaly, findings suggest embryo survival requires at least one functional gene copy.

    The University of Cologne Study (February 2024):

    • Researchers removed all functional SASS6 genes from mouse embryo-derived cells.
    • Even without the genes, cells could make abnormal but passable centrioles (structures needed for cell division).
    • When these cells were prompted to become neurons, the centrioles disappeared, preventing the cells from becoming neurons.

    Consanguinity and Genetic Risk of Microcephaly

    • Expert Insight:
      • Researchers explained that over 70% of congenital microcephaly cases come from consanguineous marriages.
      • Such marriages increase the risk of inheriting mutated genes from both parents.
    • Genetic Causes:
      • Mutations in 30 genes cause microcephaly.
      • 10 of these genes create proteins needed for centrioles, which are crucial for cell division.

    Ile62Thr Mutation

    • 2004 Discovery: The SASS6 gene was discovered in the roundworm C. elegans, showing its conserved function across animals.
    • Gene Suppression in C. elegans:
      • Suppressing the SASS6 gene halted new centriole assembly, stopping development.
    • 2014 Study on a Pakistani Family: Researchers found four family members with microcephaly due to the Ile62Thr mutation in the SASS6 gene.
    • The Ile62Thr mutation was introduced into the C. elegans SASS6 gene.
    • The mutation alone did not significantly impair centriole function but became deadly when combined with another mutation.
    • In humans, this mutation causes microcephaly due to its impact on centriole function.

  • NASA’s PREFIRE Mission to study Earth’s Polar Regions

    Why in the News?

    NASA launched the ” PREFIRE mission”, deploying twin CubeSats to study heat emissions in the Arctic and Antarctic regions, aiming to enhance climate research.

    What are CubeSats?

    • CubeSats are essentially miniature satellites whose basic design is a 10 cm x 10 cm x 10 cm (which makes up for “one unit” or “1U”) cube — just a little bigger than a Rubik’s cube.
    • weight not more than 1.33 kg.

    • These satellites were first developed in 1999 by California Polytechnic State University at San Luis Obispo (Cal Poly) and Stanford University as educational tools. 
    • However, owing to their low cost and less mass in comparison to traditional satellites, they began to be put in orbit for technology demonstrations, scientific research, and commercial purposes.

    About PREFIRE Mission

    • Jointly developed by NASA and the University of Wisconsin-Madison. 
    • It aims to investigate and comprehend the intricate dynamics of heat emissions from Earth’s Polar Regions, specifically focusing on the Arctic and Antarctica.

    Components:

    • CubeSats: PREFIRE employs shoebox-sized CubeSats, each measuring around 6U (6 units), equipped with advanced instrumentation to facilitate data collection.
      • They measure around 90 cm in height and nearly 120 cm in width when the solar panels, which will power the satellite, are deployed.
      • The two satellites will be placed in a near-polar orbit (a type of low Earth orbit) at an altitude of about 525 kilometres.
    • Thermal Infrared Spectrometers (TIRS): Each CubeSat is outfitted with a Thermal Infrared Spectrometer, meticulously engineered to measure far-infrared radiation emitted by the Polar Regions.

    Mission Objectives:

    1. Investigate heat radiated from Earth’s Polar Regions into space and its impact on climate.
    2. Employ thermal infrared spectrometers to measure far-infrared energy emitted by Earth’s surface and atmosphere.
    3. Improve understanding of the greenhouse effect at the poles and its implications for climate change.
    4. Enhance climate and ice models to predict changes in sea level, weather, snow, and ice cover in a warming world.

    Why study heat budget of the Poles?

    • A large amount of the heat radiated from the Arctic and Antarctica is emitted as far-infrared radiation wavelengths of 3 μm to 1,000 μm within the infrared range of electromagnetic radiation.
    • However, there is currently no way to measure this type of energy.
    • As a result, there is a gap in knowledge about the planet’s energy budget.

    Significance of PREFIRE

    • PREFIRE’s observations will enhance predictions of climate and environmental changes, aiding in mitigating the effects of global warming.
    • Data collected will contribute to updating climate models and improving understanding of Earth’s atmospheric dynamics.

  • Omega-3 Fatty Acids and its Health Impacts

    Why in the News?

    • Fish oil supplements, highly regarded for their high omega-3 fatty acid content, have long been associated with heart health benefits.
      • A recent study has caused controversy by raising the possibility that these supplements may be as harmful as previously thought.

    What are Fatty Acids?


    Fatty acids are crucial lipids (fats and oils) essential for various biological functions (Fatty Acid + Glycerol = Fats). They are carboxylic acids with a long aliphatic chain, either saturated or unsaturated.

    • Basic Structure: Consists of a hydrocarbon chain with a terminal carboxyl group (-COOH). The length and degree of saturation of the hydrocarbon chain can vary.
    • Roles in the Body: Serve as energy sources, components of cell membranes, and precursors for bioactive lipids.

    Types of Fatty Acids

    Fatty acids are classified based on the presence and number of double bonds in their hydrocarbon chain:

    1. Saturated Fatty Acids (SFA)
      • Structure: Contain no double bonds between carbon atoms; the hydrocarbon chain is saturated with hydrogen atoms.
      • Properties: Typically solid at room temperature.
      • Sources: Animal fats, coconut oil, palm oil, dairy products.
      • Examples: Palmitic acid, stearic acid.
    2. Monounsaturated Fatty Acids (MUFA)
      • Structure: Contain one double bond in the hydrocarbon chain.
      • Properties: Generally liquid at room temperature but solidify when chilled.
      • Sources: Olive oil, canola oil, peanut oil, avocados, nuts.
      • Examples: Oleic acid.
    3. Polyunsaturated Fatty Acids (PUFA)
      • Structure: Contain two or more double bonds in the hydrocarbon chain.
      • Properties: Liquid at room temperature and in the refrigerator.
      • Sources: Fish, flax seeds, walnuts, sunflower oil, corn oil.
      • Examples:
    1. Omega-3 Fatty Acids: Alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA).
    2. Omega-6 Fatty Acids: Linoleic acid, arachidonic acid.
    1. Trans Fatty Acids
      • Formation: Produced by the industrial process of hydrogenation of unsaturated fats, or naturally in the guts of some animals.
      • Properties: Similar to saturated fats, solid at room temperature.
      • Health Impact: Associated with negative cardiovascular effects.
      • Sources: Margarine, partially hydrogenated oils, and some baked goods.

    What are Omega-3 Fatty Acids?

    • Omega-3 fatty acids (omega-3s) are polyunsaturated fats that perform important functions in the human body.
    • There are three main types of omega-3 fatty acids:
      • EPA (eicosapentaenoic acid). EPA is a “marine omega-3” because it’s found in fish.
      • DHA (docosahexaenoic acid). DHA is also a marine omega-3 found in fish.
      • ALA (alpha-linolenic acid). ALA is the form of omega-3 found in plants.
      • When we get ALA from food, the human body can turn some of the ALA into EPA and subsequently to DHA. However, this process provides just a small amount of EPA and DHA. So, dietary sources of EPA and DHA (like fish) are essential.

    Functions of Omega-s fatty acids:

      • They help to provide structure and supporting interactions between cells.
      • Omega-3s are concentrated in high levels in cells in human eyes and brain.
      • They provide the human body with energy (calories) and support the health of many body systems.  These include the human cardiovascular system and endocrine system.

    Significance of Omega-3 fatty acids:

    • Omega-3 fatty acids have many potential benefits for human cardiovascular health.
    • One key benefit is that they help lower human triglyceride levels.
      • Too many triglycerides in human blood (hypertriglyceridemia) raise human risk of atherosclerosis, and through this, can increase human risk of heart disease and stroke. So, it’s important to keep triglyceride levels under control.
    • Omega-3s may help us by raising human HDL (good) cholesterol and lowering human blood pressure.
      • Some studies show omega-3s may lower human risk for Cardiovascular disease (CVD), and hence lowering the sudden death caused by an abnormal heart rhythm (arrhythmia), and blood clots.
    • Beyond heart health, omega-3s may help lower the human risk of developing some forms of cancer, including breast cancer, Alzheimer’s disease, and dementia, age-related macular degeneration (AMD), research continues to investigate these and other possible benefits.

    PYQ:

    [2011] A company marketing food products advertises that its items do not contain trans-fats. What does this campaign signify to the customers?

    1. The food products are not made out of hydrogenated oils.
