Razor-thin silk 'dampens noise by 75%' — could be game-changer for sound-proofing homes and offices
By Sascha Pare published
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.
DARPA considers 6 new designs for uncrewed VTOL aircraft that carry weapons payloads — with test flights set for 2026
By Rory Bathgate published
Lightweight fighter aircraft with no pilots could support conventional military missions while being easier to launch and recover.
Charging future EVs could take seconds with new sodium-ion battery tech
By Owen Hughes published
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.
DARPA's autonomous 'Manta Ray' drone can glide through ocean depths undetected
By Sascha Pare published
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.
World's fastest camera captures footage at 156 trillion frames per second
By Edd Gent published
This camera can generate clips of breathtakingly quick processes — and could help scientists create ultrafast magnetic memory and pioneering ultrasonic medical treatments.
Superfast drone fitted with new 'rotating detonation rocket engine' approaches the speed of sound
By Peter Ray Allison published
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.
Baltimore bridge collapse: an engineer explains what happened, and what needs to change
By Colin Caprani published
Why did the bridge collapse, and what can we do to make other bridges more safe against such collapse?
AI drone that could hunt and kill people built in just hours by scientist 'for a game'
By Keumars Afifi-Sabet published
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.
Record-smashing Chinese maglev hyperloop train hits 387 mph and could someday outpace a plane
By Keumars Afifi-Sabet published
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.
This tiny radioactive battery can last 50 years without recharging — and it's coming in 2025
By Victoria Atkinson published
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.
