Project to test and improve deep-learning algorithms for enhanced security. New adversarial techniques developed by engineers at Southwest Research Institute can make objects “invisible” to image detection systems that use deep-learning algorithms...

Scientists have made inroads in integrating electronic sensors with personalized 3D-printed prosthetics. With the growth of 3D printing, it’s entirely possible to 3D print your own prosthetic from models found in open-source databases. But those models lack personalized electronic user interfaces like those found in costly, state-of-the-art prosthetics.

Now, a Virginia Tech professor and his interdisciplinary team of undergraduate student researchers have made inroads in integrating electronic sensors with personalized 3D-printed prosthetics – a development that could one day lead to more affordable electric-powered prost...

Imagine being able to hear people whispering in the next room, while the raucous party in your own room is inaudible to the whisperers. Yale researchers have found a way to do just that – make sound flow in one direction – within a fundamental technology found in everything from cell phones to gravitational wave detectors.

What’s more, the researchers have used the same idea to control the flow of heat in one direction...

An international team of researchers has put a theory speculated by the late Stephen Hawking to its most rigorous test to date, and their results have ruled out the possibility that primordial black holes smaller than a tenth of a millimeter make up most of dark matter. Details of their study have been published in this week’s Nature Astronomy.

Scientists know that 85% of the matter in the Universe is made up of dark matter. Its gravitational force prevents stars in our Milky Way from flying apart...
