Communications

It might soon be possible to make selfies look like a professional photographer took them, thanks to graphics researchers at MIT.

Cells communicate by sending and receiving chemical signals and researchers are learning how to decipher, create and even hijack these conversations.

You could generate the electricity needed to charge your smartphone just by walking around, with a new device called a triboelectric generator, researchers say.

Wearable generators can supply portable, clean energy for powering our mobile devices.

The U.S. Defense Advanced Research Projects Agency, or DARPA, is developing a military drone capable of avoiding hostile threats on the ground, such as ambushes and improvised explosive devices.
