Engineering is a diverse branch of science and technology devoted to designing, building, problem-solving and finding practical uses for scientific discoveries. Live Science guides you through the different types of engineering— mechanical engineering, electrical engineering, chemical engineering, aerospace engineering and many more — with explainers on everything from who invented the telephone to how Bluetooth works.
Our expert writers and editors also scour the internet to break down the biggest engineering stories of the day, like biodegradable bullets or the world’s longest bridges. So, if you've got a mind for the mechanical, check out our latest engineering news, features and articles.
Latest about Engineering
'Holy grail' of solar technology set to consign 'unsustainable silicon' to history
Solar energy breakthrough sees scientists stabilize perovskite crystals for use in future solar panels, promising more efficient and sustainable green technology.
DARPA's military-grade 'quantum laser' will use entangled photons to outshine conventional laser beams
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.
Razor-thin silk 'dampens noise by 75%' — could be game-changer for sound-proofing homes and offices
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
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
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
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
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
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.
