Feeling objects that aren’t there
A new technology uses high-frequency sound waves to create virtual objects you can feel. Its uses include better video games and safer driving.

Sewing circuits: A crafty way to get kids interested in STEM
Many classrooms teach electric circuits with batteries and wires. But with e-textiles, students can help design and light up their own art projects.

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.

Cool Jobs: The power of wind
Science and engineering careers explore all aspects of wind, from terrible tornadoes to aeronautics and clean energy.

When smartphones go to school
Students who use smartphones and other mobile technology in class may well be driven to distraction. And that can hurt grades, studies show.

Flexible electronics track sweat
A flexible, wireless health monitor that can wrap around the wrist tracks temperature and analyzes sweat to detect signs of too much water loss.

Wildlife forensics turns to eDNA
Environmental DNA, or eDNA, tells biologists what species have been around — even when they’re out of sight or have temporarily moved on.

Boom! Sounding out the enemy
Armistice Day marked the end of the Great War. But what arguably won the war was acoustics — the science of sound. It allowed Allied troops to home in on and rout the enemy.

Males and females respond to head hits differently
Men and women are playing sports equally — and getting concussions in comparable numbers. But how their brains respond may differ greatly.

These bubbles treat wounds
New research shows bubble-powered drugs can travel upstream, against the flow of blood, to seal wounds shut.
