New research uncovers how microbes shape ecosystem resilience
Most people think of microbes in simple terms: Some make you sick, while others help keep you healthy. But microbes' influence stretches far beyond human bodies. These astonishingly complex organisms regulate the health of forests, oceans and grasslands and determine how
Some glaciers can suddenly surge forward—with dangerous consequences
It's difficult to forget standing in front of a glacier that is advancing toward you, towering ice pillars constantly cracking as they inch forward. The motion is too slow to see in real time but is obvious from one day to the next.
Scientists used brain stimulation to make people more generous
A new study suggests that generosity may be more than a moral lesson—it could be shaped by how different parts of the brain work together. By gently stimulating two brain regions and syncing their activity, researchers found that people became more willing to share money with
