Many electric vehicles are powered by batteries that contain cobalt — a metal that carries high financial, environmental, and social costs. MIT researchers have now designed a battery material that could offer a more sustainable way to power electric cars. The new lithium-ion battery includes a cathode based on organic materials,

A combined team of engineers from NASA Ames Research Center and KBR has designed and built a robot system that can autonomously build structures using specially designed lattice blocks. In their paper published in the journal Science Robotics, the group describes the robots and the lattice blocks they use to

MIT researchers have developed a battery-free, self-powered sensor that can harvest energy from its environment. Because it requires no battery that must be recharged or replaced, and because it requires no special wiring, such a sensor could be embedded in a hard-to-reach place, like inside the inner workings of a ship’s

You’re familiar with Karel Čapek, right? If not, you should be—he’s the guy who (along with his brother Josef) invented the word “robot.” Čapek introduced robots to the world in 1921, when his play “R.U.R.” (subtitled “Rossum’s Universal Robots”) was first performed in Prague. It was performed in New York

OrienSpace, a China space startup, reportedly launched the world's most powerful solid-fuel rocket from a ship off the eastern coast. The rocket, Gravity-1, falls in the same category as SpaceX's Falcon 9 rocket. However, it is not a reusable launch system yet. The aerospace sector in China has made some great
