More than 1 billion people worldwide are now estimated to have obesity
A new analysis suggests that the prevalence of obesity has doubled in women, tripled in men and quadrupled in children and adolescents from 1990 to 2022.
- Genetics
A genetic parasite may explain why humans and other apes lack tails
Around 25 million years ago, a stretch of DNA inserted itself into an ancestral ape’s genome, an event that might have taken our tails away.
