    Quantum Diamond Microscope

    IIT Bombay develops India’s first Quantum Diamond Microscope under the National Quantum Mission.

    About Quantum Diamond Microscope

    • Technology: Uses nitrogen-vacancy (NV) centres in diamond to image magnetic fields at nanoscale resolution at room temperature.
    • Applications: Enables advanced research in neuroscience, materials science and non-destructive semiconductor testing.
    • Significance: Secures India’s first patent in quantum sensing and strengthens national capabilities in frontier instrumentation.

    Fourier Transform Infrared Spectroscopy

    Recent reports highlight the use of FTIR spectroscopy as a rapid and effective tool for detecting material evidence in post-blast forensic investigations.

    About Fourier Transform Infrared Spectroscopy

    • It is a technique used to analyze materials by measuring how they absorb infrared light
    • It uses a special device called an interferometer to record data, which is then processed by a computer to make a graph (called a spectrum).
    • Significance: non-destructive (preserve sample); require minimal material, provides both qualitative & quantitative data etc.
    • Applications: Commonly used across fields such as pharmaceuticals, materials science, environmental analysis, and forensics.

    Gynandromorphism

    Scientists in Thailand discovered a rare spider that is half-female and half-male (gynandromorphism) named Damarchus inazuma.

    About Gynandromorphism

    • It is an abnormal reproductive condition in which both female and male characteristics are displayed in the same individual.
    • It is most frequently recognized in organisms that have strong sexual dimorphism such as certain butterflies, spiders and birds.
    • Cause: It is typically an event in mitosis during early development
      • One of the dividing cells does not split its sex chromosomes, producing mixed male/female cell lines.

    DNA Identification

    DNA Identification/profiling used to identify suspects or victims at Red fort blast site.

    DNA Identification

    • It is a technique used to identify individuals by analyzing unique patterns in their DNA. 

    Key Methods 

    • Short Tandem Repeat (STR): Examines short repeating DNA sequences in the nucleus. 
    • Mitochondrial DNA (mtDNA): Used if nuclear DNA is degraded. mtDNA is abundant and maternally inherited, allowing matches with maternal relatives.
    • Y Chromosome: Focuses on STRs on the Y chromosome, inherited father to son. Identifies male victims by matching paternal male relatives.
    • Single Nucleotide Polymorphisms (SNPs): Used for highly degraded DNA. 
      • SNPs are single-base differences unique to individuals, matched with personal items like toothbrushes.

    Ricin and Ammonium Nitrate

    Recently terror attacks were averted related to Ricin poison and Ammonium Nitrate.

    About Ricin

    • It is a protein found naturally in castor beans and can be made from waste residue of castor beans.
    • Lethal poison: Even 1 mg mixed in food can kill an adult. There is no antidote or specific treatment for ricin poisoning.
    • It works by getting inside the cells of a person's body and preventing the cells from making the proteins they need.

    Ammonium Nitrate

    • Pure ammonium nitrate (NH4NO3) is a white, water-soluble, crystalline substance with a melting point of 170°C.
    • It is not explosive by itself. However, it is one of the ingredients used for the manufacture of explosives.

    Protection of Plant Varieties and Farmers’ Rights (PPV&FRA) Act, 2001

    ‘Plant Genome Saviour Awards Ceremony’ was held to celebrate 25 years of the Protection of Plant Varieties and Farmers’ Rights (PPV&FRA) Act, 2001.

    About PPV&FRA Act, 2001

    • Objectives: To establish an effective protection system for plant varieties, farmers' and breeders' rights; encourage new variety development and seed industry growth.
    • It recognizes following rights:
      • Farmers’ rights: Registration and protection of new, farmers', and extant varieties; rewards for conservation. 
      • Researchers’ rights: Use of any registered variety for experiments. 
      • Breeders’ rights: Exclusive rights to produce, sell, import or export etc.
    • Protection of Plant Varieties and Farmers' Rights Authority (PPV&FRA): Established in 2005 as a statutory body under Ministry of Agriculture and Farmers Welfare.
      • Functions: Registration of new plant varieties, national gene bank etc.

    Aurora

    Auroras were witnessed in Northern America, Australia etc. due to a cannibal solar storm.

    • A cannibal solar storm happens when a faster solar storm catches up with an earlier storm, resulting in a stronger storm, affecting GPS and power systems.

    About Aurora

    • An aurora is a natural light display in the night sky, usually only appearing in lower Polar Regions.
    • They occur when high-energy charged particles from the Sun collide with atoms in the upper atmosphere.
      • E.g. Oxygen (green and red light), Nitrogen (blue and purple).
    • Near the North Pole, it is called an aurora borealis or northern lights and near the South Pole, it is called aurora australis or the southern lights.

    Pratyush Sinha Committee

    A SEBI-appointed High-Level Committee (HLC), under the chairmanship of Pratyush Sinha recommended stronger rules to prevent conflicts of interest among top officials within SEBI.

    Key Recommendations of the Committee

    • Mandatory Disclosure: Of assets and liabilities by the Chairperson, whole-time members and senior officers.
    • Insider Classification: Top SEBI leadership to be categorised as “insiders” under insider-trading regulations.
    • Investment Restrictions: Senior officials and dependent family members allowed investing only through pooled, professionally-managed funds.
    • Ethics Oversight: Creation of an Office of Ethics & Compliance, digital disclosure registry, and formal recusal reporting.
    • Dedicated whistleblower channel for conflict of interest reporting.
