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 ...

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

In real life, mutants can arise when their DNA changes to give them an advantage over the rest of the population. A team from ...

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 ...

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 ...

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 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 ...

Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random chance, but because some are naturally favored. Advanced sequencing revealed ...
