One of the most shocking discoveries of the human-genome project was that very little separates humans, genetically speaking, from yeast or roundworms. In response to all the hand-wringing that ...

Biological science has made such astonishing leaps in the last few decades, such as precise gene editing, that scientists are now tackling the next logical — yet inherently controversial — step: ...

Lead exposure may have spelled evolutionary success for humans—and extinction for our ancient cousins—but other scientists ...

When we think of lead poisoning, most of us imagine modern human-made pollution, paint, old pipes, or exhaust fumes.

An international study changes the view that exposure to the toxic metal lead is largely a post-industrial phenomenon. The ...

Putting the uniquely human version of a certain gene into mice changed the way that those animals vocalized to each other, suggesting that this gene may play a role in speech and language. Mice make a ...

Researchers at Colossal Biosciences have successfully engineered mice to express key woolly mammoth-like traits, bringing the field of de-extinction one step closer to reality. By modifying seven ...
