Cool Jobs: Researchers on the run
Researchers are taking running to extremes, from Olympic lizards to treadmills in space. The goal is to learn how athletes of all kinds can stay healthier.

Bubbles may have sheltered Earth’s early life
For Earth’s earliest inhabitants, a bubble on the beach would have been the next best thing to a safety blanket.

Allergies linked to obesity and heart risks
Children and teens with asthma, allergies or other autoimmune conditions tend to be overweight and show symptoms of heart-disease risks, a new study finds.

Gene editing swats at mosquitoes
A new genetic technique can render insects that spread malaria unable to reproduce.

New gene resists our last-ditch drug
Antibiotic resistance continues to grow. Now, scientists have found a tiny loop of DNA that resists a drug doctors use as a last line of defense.

Expert panel approves human gene editing
Scientists have recently been reporting big advances in the ability to tweak the genes of living organisms, including people. But some question the ethics of doing that. A panel of experts now says such research can go ahead — with one major exception.

Banana threat: Attack of the clones
Researchers find that disease-causing fungi — all clones of one another — will continue to infect banana plants unless new steps are taken to stop their spread.
- Humans
News Brief: Ancient teeth point to Neandertal relatives
New analyses of some teeth found in Siberia indicate that Neandertal cousins known as Denisovans lived there for at least 60,000 years. That would have had them around the same place as modern humans — and at nearly the same time.

Predatory dinos were truly big-mouths
Large meat-eating dinosaurs could open their mouths wide to grab big prey. Vegetarians would have had a more limited gape, a new study suggests.

Profile: A human touch for animals
Temple Grandin uses her own autism to understand how animals think. The animal scientist is famous for fostering the humane treatment of livestock.

Wildlife forensics turns to eDNA
Environmental DNA, or eDNA, tells biologists what species have been around — even when they’re out of sight or have temporarily moved on.

When every face is a stranger’s face
Some people can’t recognize faces — any faces, even their mother’s. Scientists are working to understand this ‘face blindness’ and help those who suffer from it.
