Caterpillar treats and tricks ants by oozing spiked juice
Caterpillars ooze droplets that lure ants away from colony duties to instead lick and defend their drug source, new lab tests suggest.

Fukushima contamination affects butterfly larvae
Butterfly larvae fed leaves with radioactive cesium from the Fukushima nuclear disaster had a higher rate of death and development abnormalities than larvae that got leaves from a location farther from the accident.

The brain’s blueprint for aging is set early in life
The brain's decline may mirror its beginning, offering clues to aging.

A protein battle underlies the beauty of orchids
The petal-and-lip shape that draws pollinators to orchids results from a competition between two protein complexes, a new study finds.

Winter road salting reshapes next summer’s butterflies
Winter road salt treatments boost sodium in roadside plants and alter development for monarch butterflies.
- Genetics
GMOs haven’t delivered on their promises — or risks
Genetically modified foods have been studied extensively and are abundant on supermarket shelves, but they haven’t managed to end world hunger yet.
