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 ...

Human aging is not what natural selection failed to prevent. It is what happens when selection simply has nothing left to act ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

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 ...

What causes autoimmune disease? A new study finds that somatic mutations in immune checkpoint genes like PDL1 trigger the ...

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 ...

Scientists from the Broad Institute of MIT and Harvard in Cambridge, Massachusetts, have identified novel mutations in bacteria that promote the evolution of high-level antibiotic resistance. The ...

A new platform for studying mtDNA mutations implicated in human disease could help accelerate treatments for mitochondrial ...

Rachel Robson, assistant professor of biology at Morningside College, and Susan Burns, associate dean for academic affairs, collaborated on an article that was published in the May issue of the ...
