Tracing the evolutionary history of chemical warfare between plants and insects

A new study published in Nature Ecology & Evolution connects plant and insect physiology, chemical ecology, molecular function, and evolutionary analysis to offer a new perspective on plant–insect coevolution. The study was ...

Flowers have a 'biological clock' that times blooming and scent to match insects

Morning-blooming morning glories and flowers that release fragrance at night seem as if they know the time. A KAIST research team has uncovered, at the molecular level, the workings of a "biological clock" aligned with insect ...

Massive insect body size 300 million years ago may not have been due to high atmospheric oxygen

Three-hundred-million years ago, Earth was very different. The continents had coalesced into Pangea, which was dominated in its equatorial regions by vast coal-swamp forests. With high atmospheric oxygen levels, wildfires ...
