Devil worm genes hold clues for how some animals survive extreme heat
Devil worms have many extra copies of genes tied to heat stress and cell death, which may help the critters survive deep underground, a study finds.

Why screening DNA for ‘designer babies’ probably won’t work
While simulations suggest it’s possible to predict a child’s height from looking at an embryo’s DNA, real-world examples say otherwise.

Flipping a molecular switch can turn warrior ants into foragers
Toggling one protein soon after hatching makes Florida carpenter ants turn from fighting to hunting for food.
- Humans
Humans’ maternal ancestors may have arisen 200,000 years ago in southern Africa
New DNA findings on humankind’s maternal roots don’t offer a complete picture of how and when Homo sapiens emerged.

A precision drug for prostate cancer may slow the disease’s spread
The drug olaparib could be used to treat men with certain genetic mutations and severe types of prostate cancer, a clinical trial finds.

Ancient European households combined the rich and poor
Homes combined “haves” and “have-nots” in a male-run system, suggests a study that challenges traditional views of ancient social stratification.

How tardigrades protect their DNA to defy death
Tardigrades encase their DNA in a cloud of protective protein to shield from damage by radiation or drying out.

Stanley Qi gives CRISPR a makeover to redefine genetic engineering
By adapting CRISPR/Cas9, Stanley Qi has given genetic engineers a plethora of new tools.

Dog behaviors like aggression and fearfulness are linked to breed genetics
A study looking at how 101 dog breeds behave finds a strong association between genetics and 14 personality traits.

Personalized diets may be the future of nutrition. But the science isn’t all there yet
How a person responds to food depends on more than the food itself. But what exactly is still a confusing mix of genes, microbes and other factors.

Losing genes may have helped whales’ ancestors adapt to life under the sea
Jettisoning genes tied to saliva and the lungs, among others, could have smoothed ancient cetaceans’ land-to-water transition 50 million years ago.

Disabling one protein might one day lead to a cure for the common cold
Scientists have identified a protein in humans that some viruses, including those that cause colds, need to spread.
