Researchers at the USC Viterbi School of Engineering are using generative adversarial networks (GANs) — technology best known for creating deepfake videos and photorealistic human faces — to improve brain-computer interfaces for people with disabilities.

In a paper published in Nature Biomedical Engineering, the team successfully taught an AI to generate synthetic brain activity data. The data, specifically neural signals called spike trains, can be fed into machine-learning algorithms to improve the usability of brain-computer interfaces (BCI).

BCI systems work by analyzing a person’s brain signals and translating that neur...

Even after 30 months in space, The Planetary Society’s LightSail 2 mission continues to successfully “sail on sunbeams,” demonstrating solar sail technology in Earth orbit. The mission is providing hard data for future missions that hope to employ solar sails to explore the cosmos.

LightSail 2, a small cubesat, launched in June 2019 on a SpaceX Falcon Heavy, as ...

Discovery could lead to improvements in medical devices and electronics. An international team of researchers from the University of Minnesota Twin Cities and Kiel University in Germany have discovered a path that could lead to shape-shifting ceramic materials...

When Earth formed 4.5 billion years ago, any phosphorus that was present likely sank into the molten core because of the element’s distinct chemical properties. However, phosphorus is essential for life; it is found in DNA, RNA, and other important biological molecules. So it is probable that the phosphorus that made life possible was delivered to Earth’s surface from extraterrestrial origins, and previous studies have suggested meteorites as potential sources.

Now, P...
