A genomic atlas of Nematostella vectensis reveals how primitive animals created multiple cell types millions of years ago, ...

A new study from Bar-Ilan University shows that one of sleep's core functions originated hundreds of millions of years ago in ...

The genetic code acts as life’s instruction manual, telling cells how to build proteins from DNA and RNA. Though it's a marvel of molecular precision, the path it took to evolve remains unclear. Fresh ...

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

'Random DNA' is naturally active in the one-celled fungi yeast, while such DNA is turned off as its natural state in mammalian cells, despite their having a common ancestor a billion years ago and the ...

Little is known about why the woolly rhinoceros went extinct around 14,000 years ago. Scientists have found clues in an unusual source: the frozen remains of an ice age wolf.

A new theory that explains why the language of our genes is more complex than it needs to be also suggests that the primordial soup where life began on earth was hot and not cold, as many scientists ...

When Charles Darwin first proposed how evolution works in 1859, it seemed plausible. Tiny changes stack up over time, eventually leading a species to become something entirely different. Aside from ...
