Researchers have identified specific genes containing rare mutations that significantly increase the likelihood of developing attention deficit hyperactivity disorder. These findings, published in the ...

Thousands of previously “invisible” microproteins—tiny chains of fewer than 100 amino acids—can profoundly change human biology when mutated. A fundamental discovery is overturning decades of ...

In our earliest science lessons, we learned that anything denser than water sinks. The denser something is, the more easily it sinks. This is seen in people who are more muscular, because muscle is ...

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 ...
