Scientists demonstrated a 3D silicon chip architecture that stacks circuits on top of one another, opening a potential path to higher computing performance and greater chip density as conventional scaling becomes increasingly challenging.
Nuclear Power Takes a New Route to Space
The BOHR satellite, launched in July, demonstrated a commercially developed nuclear-powered spacecraft technology using tritium-based betavoltaic power. Unlike conventional solar-powered satellites, the system generates electricity from radioactive decay, potentially enabling…
