Earth’s ongoing fever threatens to push entire forests toward this heat limit — and possible death.
The innovative process concentrates microplastics within a flowing liquid. A two-step process then removes the potentially toxic bits.
Solar rays in this high-altitude desert at times rival the light intensity on Venus.
Mud at the bottom of this lake holds a record showing how humanity has been changing our planet. But the Anthropocene isn’t an official new epoch yet.
A prototype fabric could help keep cars, buildings and other spaces cooler during heat waves while also reducing greenhouse-gas emissions.

Using saltwater would allow coastal cities to save their freshwater for drinking and to reduce their carbon footprints. Some could save money, too.
Microplastics in the soil hinder plant growth. But two finalists at Regeneron ISEF found that fungi and farm waste can reduce the harm.
The rainbow palette and cooling powers of new plant-based films comes from their microscopic surface patterns of tiny crystals.
Schools that replaced or upgraded old diesel school buses increased student attendance rates, new research shows.
