MPN-BP transformation is driven by sequential mutations disrupting genomic stability, with TP53 mutations being strong predictors of progression. TP53 mutations confer a selective growth advantage, ...

Hidden within fish DNA are powerful genetic twists that may explain one of nature’s biggest mysteries: how new species form so quickly. In Lake Malawi, hundreds of cichlid fish species evolved at ...

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 ...

Some of your most important life partners are the mitochondria that power all your cells. You and these little cellular ...

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 ...

For decades, ever since biologists recognized the potential environmental harms from climate change, they have worried that ...

It usually takes millions of years for new species to evolve, but not for fish in one African lake.

Learn how the Amazon molly, an all-female fish that reproduces asexually, uses gene conversion to maintain healthy DNA and ...

Marek’s disease can be pervasive in chicken houses. Chickens infected by this highly contagious viral disease often develop tumors, become paralyzed and die. They can shed the virus through their skin ...
