Low-fiber diets make gut microbes poop out
A low-fiber diet makes for low bacterial diversity in mice. A new study shows those mice can then pass a denuded microbiome on to their offspring.
- Neuroscience
Measuring brain waves may help predict a patient’s response to anesthesia
Brain signatures hint at whether a person will resist or succumb to anesthesia.
- Archaeology
Humans visited Arctic earlier than thought
Human weapon injuries on mammoth bones show humans were in the Arctic up to 15,000 years earlier than researchers thought.

Insights into sexes’ differing responses to stress
Chronic stress takes its toll on everyone. One of our reporters follows a line of research suggesting that stress hits women harder (or at least differently) than men.
- Life
Signs of food allergies may be present at birth
Overactive immune cells may prime babies for food allergies.
