NASA to test radiation-tolerant computing solution in space
The Radiation Tolerant Computer (RadPC) payload undergoes final inspection at Montana State University in Bozeman, which is leading the payload project. RadPC is one of the next 10 NASA payloads scheduled for delivery for NASA’s Commercial Lunar Payload Services (CLPS) initiative in 2025. The RadPC prototype has previously been tested on the International Space Station and Earth-orbiting satellites, and the…

Discovery of bistable nanocrystals promises faster, more energy-efficient optical computing
Optically bistable nanocrystals can store information that is written and read entirely through light, making them useful for building small and scalable optical memory units. These nanocrystals are controlled by a laser. One provides continuous power and the other triggers the light emission after a short pulse. This feature mimics the operation of electronic transistors and paves the way for…

Energy-efficient computing using magnetic vortexes
Voltage is used to move skyrmions on a triangular thin film. From the skyrmion’s movement, the type of hand gesture the system has detected can be interpreted. Credit: Grischa Beneke / JGU Researchers at Johannes Gutenberg University Mainz (JGU) have now succeeded in enhancing the Brownian motion reservoir computing framework by recording hand gestures, transferring them to a system and…
