High-quality diet may have led to bigger human brain: CSIR-CCMB-led international study reveals genetic link between diet and brain size

The research team had analysed over 8,000 genes from 50 whole genomes across primate species to understand how brain size co-evolved with diet and to identify the specific genes that may have helped make it happen. | Photo Credit: Graphics: SUBYENDHU GANGULY Our ancestors’ shift to higher-quality diets, especially with use of fire and consumption … Read more

Endocrine disruptors in plastic waste: a new public health threat

Plastics have revolutionised modern living with their convenience and affordability, but this same ubiquity is spawning an invisible, long-term health crisis. Beyond choking oceans and clogging landfills, plastics are now infiltrating our bodies through microplastic particles and a cocktail of endocrine-disrupting chemicals (EDCs). The evidence is clear and deeply concerning: these substances are interfering with … Read more

Why don’t birds get electrocuted on wires?

If we tried the same thing, the result would be… well, shocking. So what makes birds different? Let’s understand how electricity works. Electricity flows through metal wires, just like water flows through pipes. It moves from a place with high voltage (electric pressure) to a place with low voltage. For electricity to flow, it needs … Read more
