    Gold’s Cosmic Origins from Magnetar Flares

    Why in the News?

    A new study by Columbia University, suggests that the universe may have an alternate mechanism for producing gold — not just in neutron star collisions, as previously believed, but also in magnetar flares.

    Gold's Cosmic Origins from Magnetar Flares

    What are Magnetars?

    • Magnetars are a rare type of neutron star with immensely strong magnetic fields, among the most powerful in the universe.
    • They are formed when a massive star collapses during a supernova, leaving a highly dense stellar core.
    • Due to magnetic instability, magnetars sometimes release intense flares of X-rays and gamma rays.
    • These flares can be millions of times stronger than typical solar flares.
    • A magnetar’s magnetic field is estimated to be about a thousand times stronger than that of ordinary neutron stars.

    r-Process in a Magnetar Flare:

    • The r-process (rapid neutron-capture process) forms heavy elements like gold, platinum, and uranium by rapidly attaching neutrons to atomic nuclei.
    • It was earlier believed to occur mainly in neutron star mergers.
    • In a 2024 study, scientists analysed a 2004 magnetar flare followed by delayed gamma-ray emissions, recorded by NASA’s Compton Gamma Ray Observatory.
    • The radiation patterns matched those of radioactive decay from r-process elements, suggesting neutron-rich nuclei were produced.
    • Around 1.9 septillion kilograms of matter was ejected at near-light speeds, marking the first direct evidence of r-process nucleosynthesis in a magnetar flare.

    Implications for Gold Formation:

    • The study shows that magnetar flares may also produce gold and other heavy elements, not just neutron star collisions.
    • This implies such elements could have formed earlier in the universe than previously believed.
    • The findings broaden our understanding of the origins of chemical elements in space.
    • It confirms that multiple astrophysical events contribute to the formation of heavy elements.
    • It also offers a new perspective on cosmic gamma-ray bursts and ancient stellar compositions.
    [UPSC 2012] Consider the following is/are cited by the scientists as evidence/evidences for the continued expansion of the universe?

    Scientists create first ‘Pangenome’ of Asian Rice

    Why in the News?

    Chinese researchers has developed a first-of-its-kind rice pangenome by integrating genetic data from 144 wild and cultivated rice varieties from Asia (similar to the Human Genome Project).

    About the Rice Pangenome:

    • A pangenome includes both the core genes shared by all members of a species and the unique genes found in specific varieties, offering a complete view of genetic diversity.
    • The rice pangenome was built using data from 144 wild and cultivated rice varieties across Asia, making it the first comprehensive genomic resource for rice.
    • Researchers led the project from the Chinese Academy of Sciences to explore rice evolution and domestication.
    • Researchers used PacBio HiFi sequencing and advanced computational tools to detect variations, uncovering 3.87 billion base pairs of genetic material previously missing from the standard rice genome.

    Key Findings:

    • The study identified 69,531 genes, including 28,907 core genes common to all varieties and 13,728 genes unique to wild rice.
    • About 20% of all genes were exclusive to wild rice, offering potential for trait improvement in cultivated varieties.
    • The study confirmed that all Asian cultivated rice (Oryza sativa L.) originated from Or-IIIa, a subgroup of Oryza rufipogon.
    • Japonica rice was first domesticated in China, while indica rice arose later via hybridization as japonica spread across Asia.
    • Wild-specific genes were linked to environmental adaptation, phenotypic flexibility, and regenerative traits, offering insights for future crop resilience.
    • Bridging the genetic gap between wild and cultivated rice could lead to climate-resilient and high-yield varieties.

    India’s Contribution:

    • Rice is India’s staple food and the main monsoon crop, grown from June to September.
    • In 2024–25, India produced a record 220 million tonnes of rice over 51,000 hectares, with an average yield of 4.2 tonnes per hectare.
    • The Indian Council of Agricultural Research (ICAR) has developed two genome-edited rice varietiesSamba Mahsuri and MTU 1010 — known for higher yields and drought resistance; these are currently under testing.
