Birdbrain Breakthrough

Startling evidence that the human brain can grow new nerves began with unlikely studies of birdsong

When scouts discover a suitable plant near their nest, they leave a pheromone, or chemical, trail, to efficiently guide legions of worker ants to it. The workers soon stream back to the nest in six-inch-wide columns bearing loads up to ten times their own weight.

Small Matters

Millions of years ago, leafcutter ants learned to grow fungi. But how? And why? And what do they have to teach us?
