Beneficial mutations happen quite frequently, but the world changes too fast for them to stick.

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

Today, biologists taking a closer look at the animals located inside the Chernobyl Exclusion Zone (CEZ), which is about the size of Yosemite National Park, and investigating how decades of radiation ...

Biology has clever ways to mask the effects of potentially harmful gene mutations. Scientists are investigating how this ...

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 bird swoops toward a bright orange-and-black moth resting on a leaf in the Amazon. It pulls up at the last second. The pattern screams “toxic,” and the bird has learned the lesson before, probably ...

Mutation dynamics in bacterial populations underpin the generation of genetic diversity that drives adaptation, speciation and the emergence of antimicrobial resistance. Spontaneous base substitutions ...

The secret to the naked mole-rats' extraordinarily long life may lie in subtle changes to just four amino acids, researchers report. According to a new study, evolutionary mutations in cGAS – an ...

Australian researchers have discovered that a single mutation in the DNA sequence for a methylation enzyme dysregulates key tumor-suppressing pathways, opening up new avenues for blood cancer ...

EVOFLUx uses DNA methylation fluctuations as molecular barcodes to trace tumor evolution, offering insights into growth, treatment resistance, and prognosis. The method requires only bulk methylation ...
