This camera can generate clips of breathtakingly quick processes — and could help scientists create ultrafast magnetic memory and pioneering ultrasonic medical treatments.

Engineers have successfully flown a drone at near-supersonic speeds thanks to a new type of engine that burns like a rocket and could one day lead to hypersonic Mach 9 commercial flights.

Why did the bridge collapse, and what can we do to make other bridges more safe against such collapse?

The scientist who configured a small drone to target people with facial recognition and chase them at full speed warns we have no defenses against such weapons.

The T-Flight is a maglev train that hit a record-breaking speed of 387 mph on a short test track — but engineers want to double that rate so the train can carry passengers at speeds faster than if they were traveling by plane.

BetaVolt's BV100 is smaller than a coin and contains a radioactive isotope of nickel that decays into copper and supplies power to a device for up to 50 years. But it probably won't power your smartphone anytime soon, an expert suggests.

Cameras recorded footage in red, blue, green and UV channels simultaneously, with openly available software processing the raw footage and converting it into different kinds of "animal vision," showing us how bees, birds, mice and dogs might see the world.

The DragonFire laser can shoot down drones and costs less than $13 a shot, the UK government claims.

Today's infrared lasers are only powerful enough to disable aerial targets, but scientists now have the keys to building high-powered laser weaponry that can 'melt' distant targets.
