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 ...

A new paper in Genome Biology and Evolution, indicates that while the COVID-19 virus has developed rapidly since 2019, it has done so within limited genetic channels. These genetic limits have ...

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 ...

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

Fi Novelist Who Disappeared for Decades In “What We Are Seeking,” the cult author Cameron Reed returns to show us a strange, ...

Vaccinating birds against bird flu reduces the spread of the disease, but may have unintended consequences. This is the warning of a new paper in the journal Science Advances, which concluded that ...

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 ...

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