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.
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.
Did Alexander Graham Bell really invent the telephone, or did he steal someone else's thunder?
Reference Bluetooth was inspired by a Nordic king and harnesses the power of radio. How has this wireless connectivity reshaped our electronic ecosystems.
Reference Working out who invented the car is not as simple as you might think as the automobile we know today had a long journey to being created.
Reference The Jaws of Life are the favoured hydraulic tool for safely removing car crash victims. The equipment can cut car frames apart and lift crushing weights from passengers.
