NASA’s Space Reactor-1 Freedom keeps moving toward a late-2028 launch as the first spacecraft ever built to run fission power beyond Earth’s orbit. Announced back in March during the agency’s Ignition event, the mission pairs a compact reactor with hardware already under construction for the canceled lunar Gateway station. That reuse lets engineers hit the […]

Most refrigerators depend on an electric compressor to move heat around, but Greenhill Forge built a working cooler that gets its energy from a wood fire and a solution of common road salt instead. Water serves as the refrigerant. When water boils it soaks up heat from whatever is around it, and the same principle […]

Hotel rooms, home offices, libraries, and school desks share one familiar problem: too many devices and too few outlets. A laptop, phone, tablet, and earbuds quickly turn a single wall socket into a puzzle of adapters and cables. UGREEN’s Nexode 100W GaN charger, priced at $39.98 (was $55), solves that with one compact unit. Three […]

Photo credit: 2026 EPFL LMTS CC BY SA 4.0Engineers in Lausanne have built a motor easy to mistake for a length of heavy sewing thread. FiberMotor, from the Soft Transducers Laboratory at EPFL, measures only 1 to 3 millimeters across and turns electricity straight into a push or a pull. Herbert Shea, who leads the […]

Four brick-shaped lithium iron phosphate cells, each rated 3.2 volts and 15 amp-hours, sit in a row and form the whole energy store of a homemade power station small enough to close a hand around. Wired end to end, they make a 12.8-volt pack that climbs to 14.6 volts when full and holds about 192 […]

Most walls do one job and then sit there. A group at Binghamton University has printed a covering that also drinks moisture from the room and turns the slow movement of that water into a small, steady current. Professor Seokheun “Sean” Choi spearheaded the experiment, with PhD students Guangya “Roger” Yuan and Yang “Lexi” Gao […]

Living muscle cells, the same kind that pull on bone inside a body, now pull a paper-thin robot through water. Researchers at MIT built a gum-stick-sized aquabot whose two fins beat when light hits them, and they steered it through a simple maze in a petri dish by flashing that light from outside the dish. […]
