Researchers have created the first complete map showing how hundreds of mutations in a key cancer gene affect tumor growth. By testing every possible mutation in a critical hotspot, they found that ...

When a wound does not heal properly, it leaves a scar. Similarly, mutations—which are permanent changes to genetic code—are ...

Consider a living cell, which can have thousands of genes. Now think of these genes as dials that can be tweaked to change how the cell grows in a given environment. Tweaking a gene can either ...

It's a fundamental principle of science: Correlation does not equal causation. Every cancer cell has genetic mutations, but not all of those mutations necessarily drive the cancer. A Harvard Medical ...

Human eggs appear to be protected against a certain type of age-related mutation. In a small study, researchers found no signs that mutations accumulate in the mitochondrial DNA of human egg cells as ...
