The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...

But some Neanderthal DNA helped modern humans survive and reproduce, and thus it has lingered in our genomes. Nowadays, ...

Humans were isolated in southern Africa for about 100,000 years, which caused them to "fall outside the range of genetic variation" seen in modern-day people, a new genetic study reveals. The finding ...

Biologists are quietly rewriting what it means to be alive, and the human body has become one of their strangest frontiers.

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

To overcome the inherent challenge of translation termination interference caused by stop codon reprogramming in mammalian cells, researchers from Peking University led by Chen Peng from College of ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Modern humans descended from ...

Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein ...

Horses have played a critical role in shaping human society, but scientists are still piecing together the story of their domestication. Reading time 3 minutes Roughly 4,500 years ago, humans forged a ...
