Researchers have created the first complete map showing how hundreds of mutations in a key cancer gene affect tumor growth.

The DNA mutations that drive evolution are generally thought to be fairly random, but a new study suggests there’s some order to the chaos. Comparing the genomes of hundreds of plants grown in a lab, ...

A new study compares the accumulation of mutations across many animal species and has shed new light on decades-old questions about the role of these genetic changes in ageing and cancer. Researchers ...

Mutations are the raw ingredient of evolution, providing variation that sometimes makes an organism more successful in its environment. But most mutations are expected to be neutral and have no impact ...

Omicron was named a "variant of concern" in part because of its peculiar set of mutations. It is not yet clear whether this variant spreads faster or causes more severe infections. Here are the ...

Mutations can work together to make a virus more fearsome, but they can also cancel one another out. This phenomenon, called epistasis, is why scientists are reluctant to speculate on Omicron. By ...

Using data to identify the genetic changes that cause healthy cells to become malignant can help doctors select therapies that specifically target the tumor. Most of the roughly 40 trillion cells of ...
