Indistinguishability Obfuscation

Indistinguishability Obfuscation (iO) is a crytographic protocol which was thought to be impossible until Aayush Jain and his advisor Amit Sahai from UCLA, together with Huijia Lin from the University of Washington, published a paper acheived IO using standard security assumptions. The purpose of iO, as I understand it, is to allow two pieces of the same data to be encrypted with all but one element being different, e.g. a key, and it would be impossible to determine the difference by comparing the two encrypted results.

Iron As Renewable Fuel

Working with researchers from TU Eindhoven, the Swinkels Family Brewers in The Netherlands are the first to employ at scale the burning of Iron as a renewable fuel. Finely ground iron powder burns cleanly at high temperatures and produces iron oxide (rust) as its only emission. Best of all, this rust can be reenrgised back in to iron powder using electricity, for use as a combustable source of energy again!

Feathered Drone

A team at École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have created a winged and feathered drone that can change the position of its wings to control speed and maneuverability during flight. In other drone news, a team at Imperial College London have created a drone that can shoot darts with sensors on them.
