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.

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.

3D Printed Textiles

MIT media lab student Jack Forman used the under extrusion of a 3D printer to print a flexible textile material. Under-extrusion is when not enough plastic is consistently poured from the nozzle of a 3D printer, resulting in gaps in the printed material. By purposefully introducing these gaps, the printed material is solid and flexible. Check out the demo video which shows rolls of material being printed as well as applications like clothing and shuttlecocks.

Nokia Moon 4G

NASA have selected Nokia to provide a 4G/LTE network on the moon. The network will be used for data transmission of vital command and control functions, remote control of rovers, real time navigation and video streaming. I'm looking forward to all the moon tiktoks :-p
