New spray technology helps pesticides stick to plant leaves to reduce polluting runoff

Reducing the amount of agricultural sprays used by farmers—including fertilizers, pesticides, and herbicides—could cut down the amount of polluting runoff that ends up in the environment while at the same time reducing ...

Light-induced symmetry changes in tiny crystals allow researchers to create materials with tailored properties

Imagine building a Lego tower with perfectly aligned blocks. Each block represents an atom in a tiny crystal, known as a quantum dot. Just like bumping the tower can shift the blocks and change its structure, external forces ...

Moiré than meets the eye: Phasons enable interlayer excitons to move at low temperatures for quantum stability

A moiré pattern appears when you stack and rotate two copies of an image with regularly repeating shapes, turning simple patterns of squares or triangles into a groovy wave pattern that moves across the combined image in ...

Chimpanzee genes have changed over time to suit local conditions: New study

Chimpanzees are humans' closest living relatives, sharing more than 98% of our DNA. They are endangered, with fewer than 250,000 left and an annual decline of between 1.5% and 6%. This is due to habitat destruction, hunting ...
