For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

A study published in the Proceedings of the National Academy of Sciences by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not ...

Mitochondria are known as the body’s “energy factories,” and their function is essential for life. Inside mitochondria, a set of complexes called the oxidative phosphorylation (OxPhos) system ...

HOW does cancer do it? How does one little cell transform itself into an invader that rages out of control? Surprisingly abruptly, according to new results that are pointing the way to ...

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

In a study published in the journal Science, researchers in Queensland and the United States discovered that the human X ...

Modern HIV medicine is based on a common genetic mutation. Now, researchers have traced where and when the mutation arose -- and how it protected our ancestors from ancient diseases. Modern HIV ...

A major evolutionary innovation has unfurled right in front of researchers’ eyes. It’s the first time evolution has been caught in the act of making such a rare and complex new trait. And because the ...
