# Bats have two copies of antibody genes, study finds 2026-08-13T11:24:07+00:00 | Health & Science | Indian Opinion Desk Corroboration: 1 independent outlet Scientists have discovered that bats possess two copies of antibody genes, a unique feature among mammals. The study, published in Science Advances and covered by The Hindu, examined vesper bats and found a duplicated heavy-chain gene system that boosts antibody diversity. This may explain how bats carry viruses like coronaviruses without falling sick. The finding challenges previous understanding of mammalian immunity and offers new avenues to prevent disease spillovers. India has 135 bat species, but they receive little research or policy attention despite their ecological importance. ## Coverage - thehindu.com Tags: antibody genes, bats, immune system, Science Advances, vesper bats, zoonotic diseases Canonical: https://indianopinion.org/bats-have-two-copies-of-antibody-genes-study-finds/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
