Sharks’ hunting paths may not be driven by math
Penguins, tuna, sharks and other marine hunters have been shown to use math to find food. But simulations suggest the behavior is a result of rough water, not complex calculation.

Mama deer respond to the cries of human babies
Deer mothers approached a speaker playing distress calls of young mammals when the frequency fell into the same range as fawns.

Training the overweight brain to abstain
A new study shows that brain changes are associated with a weight-loss behavioral intervention, but it may be a while before we can train our brains to prefer peppers over pork chops.
- Agriculture
Drug-resistant staph can cling to farm workers for days
Agricultural exposure to staph bacteria could threaten the health of laborers and people who live near farms, a study of pig farm workers suggests.
