The tech could revolutionize how spacecraft, airplanes, ships, and submarines navigate when GPS is unavailable or compromised. A US military spaceplane, the X-37B orbital test vehicle embarked on its eighth flight into space on Thursday. Much of what the X-37B does in space is secret. But it serves

The featherlight devices are smaller than a dime and need no solar panels, propellers, or engines to move. With a blast of light, the wafer-thin metal “parachutes” levitate into the air. The curious inventions are each smaller than a dime and need no solar panels, propellers, or engines to move.

Energy stored in liquid CO2 is converted back into gas to turn turbines on demand. Tech companies are throwing money at new sources of energy, from wind and solar to next-generation geothermal, nuclear, and even fusion power. But all that electricity isn’t good for much unless it can be stored then

Accurate predictions could accelerate the design of new experiments and bring practical fusion power closer. While AI chatbots grab most of the attention, deep learning is also quietly revolutionizing science and engineering. A new AI model that can help predict the outcome of fusion power

Thoughts are translated into speech in real time—with a passcode to prevent broadcasting private musings. We all talk to ourselves in our heads. It could be a pep talk heading into a wedding speech or chaotic family reunion or motivating yourself to quit procrastinating. This inner speech also
