Landing on a moving target is a challenge for all flying animals. For bumblebees, a flower swaying in the wind creates an erratic landing pad. Reaching it means matching its sideways motion while continuing to face it. When ...
Human and chimpanzee genomes are more than 98% identical, and the genes themselves barely differ. The changes that make us human are thought to hide instead in the DNA that controls when and where genes switch on.
