Gotcha! New test stalks diseases early
Chemists screen blood for disease markers by adapting a common DNA test. The test can find disease earlier, when it also may be easier to treat.

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.

Microbes mine treasure from waste
Like miniature factories, bioreactors house microbes recruited to chew through wastes to clean dirty water, make chemicals or generate electricity.

Goo-oozing deicer protects surfaces
New, slime-oozing coating might someday help reduce ice and snow buildups on road signs and aircraft wings. The inspiration? The goo produced by slugs.

Plastic that mimics insect wings kills bacteria
A new ‘antibiotic’ plastic uses nanotechnology to mimic the hairs on insect wings. Then ouch! Bacterial cells that land on it end up stabbing themselves to death.
