The idea of traveling through interstellar space using spacecraft propelled by ultrathin sails may sound like the stuff of sci-fi novels. But in fact, a program started in 2016 by Stephen Hawking and Yuri Milner, known as the Breakthrough Starshot Initiative, has been exploring the idea. The concept is to use lasers to propel miniature space probes attached to “lightsails” to reach ultrafast speeds and eventually our nearest star system, Alpha Centauri.

Caltech is leading the worldwide community working toward achieving this audacious goal.

Artificially engineered biological processes, such as perception systems, remain an elusive target for organic electronics experts due to the reliance of human senses on an adaptive network of sensory neurons, which communicate by firing in response to environmental stimuli.

A new collaboration between Northwestern University and Georgia Tech has unlocked new potential for the field by creating a novel high-performance organic electrochemical neuron (OECN) that responds within the frequency range of human neurons...

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the abundance of gamma rays in the universe.

Our home planet is bombarded with particles from outer space all the time. And while we are mostly familiar with the rocky meteorites originating from within our solar system that create fascinating shooting stars in the night sky, it’s the smallest particles that help scientists to understand the nature of the universe. Subatomic particles such as electrons or protons arriving from interstellar space and beyond are one of the fastest particles known in the universe and known as cosmic rays.

The origins and the acceleration mechanisms of the mo...

A new one-minute video game is able to accurately and efficiently identify children with autism from those who have ADHD or are neurotypical.

Developed by researchers at Kennedy Krieger Institute and Nottingham Trent University, the tool, called the Computerized Assessment of Motor Imitation (CAMI), uses motion-tracking technology to detect differences in motor imitation skills. The research is published in The British Journal of Psychiatry.

In the study, 183 children, ages 7–13, were asked to copy the dance-like movements of a video avatar for one minute, while their imitation performance was measured using ...
