Representative image. | Photo Credit: Murali Kumar K./The Hindu Conflicts lurk inside every flower with multiple seeds. The embryos jostle for food, the maternal and paternal genomes bargain over control, and pollen grains compete to be fertilised. Scientists have therefore wondered whether natural selection encourages one-parent broods that keep such quarrels to a minimum and,…

Noise-cancelling headphones have become increasingly popular, particularly among younger generations, for their ability to block out ambient noise and enhance the listening experience. Long-haul flights, public transportation, and open-plan offices all use over-ear headphones; concertgoers, bartenders all appear wearing coloured earplugs. Everyone seems to wear headphones as a required item for public spaces, whether they…

A new study has found that the X chromosome passed down to the child from the mother might be responsible for accelerated brain ageing, potentially increasing the risk of conditions like Alzheimer’s disease. Only females have two X chromosomes (XX) while males have one X and one Y (XY). Given the natural order, the X…
