AI Helps Amputees Walk With a Robotic Knee

A movie montage for modern artificial intelligence might show a computer playing millions of games of chess or Go against itself to learn how to win. Now, researchers are exploring how the reinforcement learning technique that helped DeepMind’s...

Shimi Will Now Sing to You in an Adorable Robot Voice

Human-robot interaction is easy to do badly, and very difficult to do well. One approach that has worked well for robots from R2-D2 to Kuri is to avoid the problem of language—rather than use real words to communicate with...

Bracing Medical AI Systems for Attacks

Last June, a team at Harvard Medical School and MIT showed that it’s pretty darn easy to fool an artificial intelligence system analyzing medical images. Researchers modified a few pixels in eye images, skin photos and chest X-rays to trick deep learning systems into...

New Optimization Chip Tackles Machine Learning, 5G Routing

Engineers at Georgia Tech say they’ve come up with a programmable prototype chip that efficiently solves a huge class of optimization problems, including those needed for neural network training, 5G network routing, and MRI image reconstruction. The chip’s architecture embodies...

Former NASA Engineers Building Real-Life Underwater Transformer

A transformer designed to do grunt work for the oil industry and military is coming, and it's… admittedly kind of fun to look at. Houston Mechatronics, a small company founded and led by a...

Sun-Soaking Device Turns Water Into Superheated Steam

MIT engineers have built a device that soaks up enough heat from the sun to boil water and produce “superheated” steam hotter than 100 degrees Celsius, without any expensive optics. On a sunny day,...

Ingestible Capsule Can Be Controlled Wirelessly

Researchers at MIT, Draper, and Brigham and Women’s Hospital have designed an ingestible capsule that can be controlled using Bluetooth wireless technology. The capsule, which can be customized to deliver drugs, sense environmental conditions, or both, can...

Hybrid Qubits Solve Key Hurdle To Quantum Computing

Spin-based quantum computers have the potential to tackle difficult mathematical problems that cannot be solved using ordinary computers, but many problems remain in making these machines scalable. Now, an international group of researchers led by the RIKEN...

Researchers Link Realism To Blockchain’s Promise

Depending on who you ask, blockchain technology is poised to revolutionize the world — from creating a universal currency to building a free and truly private internet. Or, the new technology, built with a combination of encryption...

Wireless ‘Pacemaker For The Brain’ Could Offer New Treatment For Neurological Disorders

A new neurostimulator developed by engineers at the University of California, Berkeley, can listen to and stimulate electric current in the brain at the same time, potentially delivering fine-tuned treatments to patients with diseases like epilepsy and...
