Could this be the end for batteries? Scientists generate electric power from Wi-Fi

A flexible material that converts radio signals into usable electric current raises the prospect of a world without batteries. Scientists in the US developed the device, known as a “rectenna”, from a semiconductor just a few atoms thick. Wi-fi signals captured by an integrated antenna are transformed into a DC current suitable for electronic circuits.…

Humans help AI software to ‘detect blind spots in self-driving cars’

Blind spots in the artificial intelligence (AI) of self-driving cars could be corrected using input from humans, new research claims. A team of researchers from the Massachusetts Institute of Technology (MIT) and tech giant Microsoft has developed a model which first puts an AI system through simulation training before putting a human through the same…

Scientists design ingestible electronic pill that can be controlled wirelessly

An electronic capsule that can be ingested and controlled wirelessly to deliver drugs has been designed by scientists, in an effort to reduce surgical procedures. Researchers at the Massachusetts Institute of Technology believe that the device could be used to provide drugs to users for a variety of diseases that require medication over longer periods…

First flight of completely silent electric aircraft, inspired by Star Trek

A revolutionary electronic aircraft propulsion system inspired by Star Trek has been tested on a working model for the first time. The five metre (16ft) wingspan glider-like plane has no propellers, turbines or any other moving parts, and is completely silent. Instead, an “ionic wind” of colliding electrically charged air molecules provides the thrust needed…
