The study of experimental evolution in Escherichia coli has provided unprecedented insights into the mechanisms of adaptive mutations, elucidating how populations diverge and optimise their fitness ...

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 ...

The number of known proteins is infinitely small in comparison to the universe of possible proteins, which could in theory be ...

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 ...

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 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 ...

In adults, damage to myelin is a hallmark of MS. In this condition, the immune system mistakenly attacks and destroys the ...

Many people hold the view that evolution in humans has come to a halt. But while modern medicine and technologies have changed the environment in which evolution operates, many scientists are in ...

A SARS-CoV-2 subvariant called BA.3.2, carrying a significant genomic deletion and mutations linked to immune evasion, has ...
