    Grey Seal Milk Complexity  

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Why in the News?

    A study published in Nature (Nov 2025) found that grey seal milk contains 332 different oligosaccharides—33% more than human breast milk, previously considered the most complex.

    Key Findings

    Highest Oligosaccharide Diversity

    • Grey seal milk contains 332 oligosaccharides
       (Human milk: ~100).
    • This is the largest number ever recorded in any mammal’s milk.

    Functions of Oligosaccharides

    • Boost immunity (protect against bacteria & viruses).
    • Support gut microbiome formation.
    • Aid digestive tract development.
    • Provide energy and growth support for pups.

    Why Grey Seal Milk is So Complex?

    • Grey seals:
      • Live in harsh, high-risk environments.
      • Mothers fast for ~18 days while feeding pups.
      • Pups grow extremely rapidly during this period.
    • Complex sugars help pups survive extreme conditions and develop strong immunity quickly.

    Study Details

    • Conducted by the University of Gothenburg (Sweden).
    • Samples collected from Atlantic grey seals on a small Scottish island.
    • Analytical method used: Deep mass spectrometry.
      • A very advanced method of mass spectrometry that can detect hundreds to thousands of molecules in a sample with very high accuracy.
    Consider the following: 

    1. Bats 

    2. Bears 

    3. Rodents 

    The phenomenon of hibernation can be observed in which of the above kinds of animals? 

    (a) 1 and 2 only 

    (b) 2 only 

    (c) 1, 2 and 3 only 

    (d) Hibernation cannot be observed in any of the above

    This PYQ is chosen because it directly addresses the peculiar biological feature (hibernation) that allows mammals to survive challenging environmental conditions, which conceptually mirrors the adaptive features of the grey seal

    Aloe vera Compounds as Potential Alzheimer’s Inhibitors  

    Prelims Only | Science Tech | Mains Paper 3: S&T – Applications In Everyday Life

    Why in the news?

    A new study (Current Pharmaceutical Analysis, 2025) suggests that common plant molecules from Aloe vera—especially Beta sitosterol—may inhibit key enzymes associated with Alzheimer’s disease (AD). Findings are based entirely on in silico (computer simulation) techniques.

    What is Computer Simulation (In Silico Research)?

    • Computer simulation, often called in silico research, refers to the use of computational tools and algorithms to model biological, chemical, or physical processes.
    • It allows scientists to predict molecular interactions, drug behavior, and biological outcomes without physical experiments.

    Alzheimer’s Disease (AD) 

    • Most common form of dementia.
    • Characterised by:
      • Memory loss
      • Cognitive decline
      • Accumulation of beta-amyloid plaques and tau tangles
      • Loss of acetylcholine, a neurotransmitter linked to learning and memory.
    • Enzymes involved in acetylcholine breakdown:
      • Acetylcholinesterase (AChE)
      • Butyrylcholinesterase (BChE)
    • Current drugs (e.g., donepezil, rivastigmine) work by inhibiting these enzymes but do not stop disease progression.

    Why Aloe vera?

    • Used for 3000+ years in traditional medicine.
    • Contains bioactive compounds such as Beta sitosterol, Succinic acid, polysaccharides, and phenolics.

    Major Findings

    • Beta sitosterol showed strong binding affinity to both enzymes:
      • AChE: −8.6 kcal/mol
      • BChE: −8.7 kcal/mol
    • The binding strength is higher than that of other screened compounds like Succinic acid.
    • ADMET results suggest:
      • Good absorption
      • Low toxicity
      • Favourable pharmacokinetic profile
    Which one of the following is the context in which the term “qubit” is mentioned? (2022)

    (a) Cloud Services 

    (b) Quantum Computing 

    (c) Visible Light Communication Technologies 

    (d) Wireless Communication Technologies

    This PYQ is chosen because it tests a fundamental concept related to the cutting edge of computational power and modelling, which is the operational domain of computer simulation.

    Vitamin B12 Deficiency & Skin Manifestations 

    Prelims Only | Science Tech | Mains Paper 3: S&T – Applications In Everyday Life

    Why in the news?

    According to a study published in Canad­ian Family Physician, Vitamin B12 deficiency often shows early dermatological symptoms—such as pigmentation, dryness, and inflammation—before neurological or hematological complications appear.

    What is Vitamin B12?

    • Water-soluble vitamins are essential for: Red blood cell formation, Nerve function, DNA synthesis and Cell growth and repair

    Why Skin Shows Early Signs?

    • B12 deficiency → reduced RBC production → low oxygen delivery to skin → visible skin changes.
    • Weak immunity and impaired nerve function further worsen dermatological issues.
    High-Risk Groups

    More prone to Vitamin B12 deficiency:

    • Vegetarians/vegans
    • Adults > 50 years
    • Individuals with:
      • Gastritis, Crohn’s disease, celiac disease
    • Those taking:
      • Antacids (PPIs/H2 blockers)
      • Metformin
    • People with poor nutrient absorption

    Mekedatu Balancing Reservoir Project

    Prelims Only | Polity | Mains Paper 2: Parliament & State Legislatures

    Why in the news?

    • Karnataka has decided to submit a revised Detailed Project Report (DPR) for the Mekedatu balancing reservoir across the Cauvery River.
    • The Supreme Court termed Tamil Nadu’s challenge as “premature”, enabling the CWMA and CWC to examine the project.

    Location & River

    • Mekedatu is located in Ramanagara district, ~100 km from Bengaluru.
    • The project is proposed on the inter-State Cauvery river.
    • Karnataka = upper riparian; Tamil Nadu = lower riparian.

    Why Does Karnataka Want It?

    • Bengaluru water demand:
      • Present: 2,600 MLD
      • Supply: 2,100 MLD → shortage of 500 MLD
    • Population to reach 20 million in 6 years → demand may rise to 4,000 MLD.
    • Shivakumar argues Mekedatu will ensure regulated release to Tamil Nadu, even in poor rainfall years.

    Why Is Tamil Nadu Opposed?

    • Trust deficit due to the history of Cauvery disputes.
    • Concern: Karnataka may store more water and release it selectively.
    • TN argues the project violates the 2018 SC judgment and Cauvery Tribunal’s final award.

    Centre’s Position

    • 2019: Karnataka submitted DPR → CWC → CWMA.
    • MoEFCC (2019): Sought an “amicable solution” due to inter-State dispute.
    • 2024 (Feb): CWMA referred DPR back to CWC after deliberations.
    • Now: DPR to be examined afresh; CWMA/CWC can facilitate dialogue.

    Constitutional & Legal Angle

    • Inter-State Rivers: Union List Entry 56 – regulation and development of inter-State rivers.
    • River Boards Act, 1956 (not effectively implemented).
    • Cauvery Water Disputes Tribunal (CWDT): Award notified in February 2013.
    • Supreme Court Judgment (2018):
      • Reallocated shares;
