X-ray platform images plasma instability for fusion energy and astrophysics

A high-power laser (red) strikes a solid wire, creating a hot plasma and accelerating fast electrons into the material. These fast, hot electrons are met by a return current of colder electrons flowing in the opposite direction, forming filament-like structures that have been visualized for the first time using the LCLS.

China Is Building a Brain-Computer Interface Industry

In a policy document released this month, China has signaled its ambition to become a world leader in brain-computer interfaces, the same technology that Elon Musk’s Neuralink and other US startups are developing. The document outlines China’s plan to create an internationally competitive BCI industry within five years, and proposes developing devices for both health and consumer uses.
