Researchers say the screen can work both indoors and outdoors, and can be adjusted to become more or less transparent depending on user needs.

Solar energy breakthrough sees scientists stabilize perovskite crystals for use in future solar panels, promising more efficient and sustainable green technology.

Prototype quantum photonic-dimer laser uses entanglement to bind photons and deliver a powerful beam of concentrated light that can shine through adverse weather like thick fog.

Researchers have engineered a silk fabric that can suppress noise by either generating sound waves that interfere with the noise or by blocking vibrations that are key to the transmission of sound.

Lightweight fighter aircraft with no pilots could support conventional military missions while being easier to launch and recover.

A new type of hybrid sodium-ion battery that offers both high capacity and rapid-charging capabilities could power mobile devices, electric vehicles and space tech.

Northrop Grumman Corporation has built its Manta Ray uncrewed underwater vehicle, which will operate long-duration missions and carry payloads into the ocean depths in partnership with DARPA.

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?
