Thousands of previously “invisible” microproteins—tiny chains of fewer than 100 amino acids—can profoundly change human ...

Researchers at Baylor College of Medicine have developed an artificial intelligence (AI) model that reveals how protein ...

In recent years, there has been growing concern over the H5N1 influenza virus. It was first identified in birds three decades ...

Key Takeaways Unique mutations in the H5N1 strain enhance replication in human cells and cause severe disease in mice. The virus has spread from birds to mammals, including dairy cows, and ...

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 ...

The human brain (about the size of 10 tennis balls) is three times bigger than a chimp’s. There are multiple theories for why we evolved large and complex brains.

A new study has raised alarm bells about the potential for the H5N1 bird flu virus to evolve into a strain sparking a human pandemic. A single mutation in the virus currently ravaging dairy farms ...

They made targeted mutations to see how the shifts altered its ability to attach to human cells. “The surprising finding,” Paulson says, was that one specific mutation seemed to be enough.
