Device fine-tunes treatment by stimulating and and recording electric current in the brain at the same time. 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 Parkinson’s.

The device, named the WAND, works like a “pacemaker for the brain,” monitoring the brain’s ele...

NASA spacecraft reaches most distant target in history...

If you’re planning to try to lose weight in 2019, you’re sure to find a fierce debate online and among friends and family about how best to do it. It seems like everyone has an opinion, and new fads emerge every year. Two major studies last year provided more fuel for a particularly polarizing topic—the role carbs play in making us fat. The studies gave scientists some clues, but, like other nutrition studies, they can’t say which diet—if any—is best for everyone...

Scientists at Tokyo Institute of Technology proposed new quasi-1D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. They performed simulations to demonstrate the spin properties of these materials and explained the mechanisms behind their behavior.

Conventional electronics is based on the movement of electrons and mainly concerns their electric charge; unfortunately, we are close to reaching the physical limits for improving electronic devices...
