Beyond Inheritance offers a new view of mutations
In her debut book, science writer Roxanne Khamsi offers a new view of mutations that’s not limited to birth and death.

Sleep and exercise may dampen genetic drivers of heart disease
Over time, immune cells acquire mutations that promote atherosclerosis. Lifestyle changes may offset these DNA glitches, new mouse data suggest.

The Amazon molly — a sex-skipping fish — hacks evolution
The Amazon molly reproduces without sex. A genomic copy-and-paste trick called gene conversion may explain how it avoids evolutionary meltdown.

Machine learning streamlines the complexities of making better proteins
The framework predicts how proteins will function with several interacting mutations and finds combinations that work well together.

Yaks may hint at a way to treat brain diseases like MS
A genetic mutation tied to keeping the brain healthy at high altitudes may point to a way to repair nerve damage, experiments in mice show.

A lab on wheels is tracking HIV spread in war-torn Ukraine
During a test drive, the mobile lab van uncovered a drug-resistant HIV strain that sprung up after the ongoing war with Russia started.

How a bacterial toxin linked to colon cancer messes with DNA
A closeup look at colibactin’s structure reveals chemical motifs that guide its mutation-wreaking “warheads” to specific stretches of DNA.

Gum disease bacteria can promote cancer growth in mice
In mice, the oral bacteria F. nucleatum can travel to mammary tissue via the bloodstream, where it can damage healthy cells.

AI tool AlphaGenome predicts how one typo can change a genetic story
The tool helps scientists understand how single-letter mutations and distant DNA regions influence gene activity, shaping health and disease risk.

Damaged DNA can spread between human cells. What could that mean for cancer?
DNA can voyage along intercellular highways called tunneling nanotubes. It’s a phenomenon that could potentially spread tumor DNA to healthy cells.

A koala population’s rapid rebound may let it escape inbreeding’s perils
As koalas in southern Australia have grown from a few hundred to almost half a million, the marsupials show signs of regaining lost genetic variation.

Finding immune cells that stop a body from attacking itself wins medicine Nobel
Shimon Sakaguchi discovered T-reg immune cells. Mary Brunkow and Fred Ramsdell identified the cells’ role in autoimmune disease.
