A new study is the first to identify how human brains grow much larger, with three times as many neurons, compared with chimpanzee and gorilla brains. The study identified a key molecular switch that can make ape brain organoids grow more like human organoids, and vice versa.
The ancestors of modern-day people living on Southeast Asian islands likely interbred with a prehistoric species called Denisovans – raising the possibility of fresh and intriguing fossil discoveries.
Researchers find that the earliest bacteria had the tools to perform a crucial step in photosynthesis, changing how we think life evolved on Earth.
Using molecular dating tools and epidemiological simulations, researchers estimate that the SARS-CoV-2 virus likely circulated undetected for two months before the first human cases of COVID-19 were described in Wuhan, China in late-December 2019.
