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

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 ...

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 ...

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 ...

Researchers published a new study, “Ongoing chromothripsis underpins osteosarcoma genome complexity and clonal evolution,” in Cell that they say solves the mystery of what drives the genomic ...

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

Evolution isn’t a single, straightforward process – it works in several distinct ways. From species splitting apart over time ...
