Common water pollutants hurt freshwater organisms
The germ killers we use and the drugs we take don’t just disappear. They can end up in the environment. There they can harm aquatic organisms, three teens showed.

Smash hit: Making ‘diamond’ that’s harder than diamonds
Scientists had suspected extreme meteorite impacts might turn graphite into an unusual type of diamond. Now they’ve seen it happen — in under a nanosecond.

Genes: How few needed for life?
Scientists rebuilt a microbe using its old genes. But not all of them. They used as few building-blocks as they could get away with and still have the life-form survive.

How to catch a gravity wave
Physicists have just announced finding gravity waves. The phenomenon was predicted a century ago by Einstein’s theory of general relativity. Here’s what it took to detect the waves.
