Kaleidocycles are flexible polyhedral structures composed of rigid tetrahedra connected along their edges to form rotating rings. Each tetrahedron is a solid 3D polygon with four triangular faces (like a triangular pyramid), ...
Researchers have developed an autonomous system for seeking out and mapping hotspots of biodiversity on coral reefs with unprecedented precision, offering a powerful new tool for studying and protecting some of the ocean's ...
Nasa is developing ways to use nuclear power to send spacecraft to their destinations. Nuclear propulsion could greatly reduce the journey time to Mars, perhaps cutting a voyage of more than six months to three or four months.
NASA's Perseverance Mars rover recently took a self-portrait against a sweeping backdrop of ancient Martian terrain at a location the science team calls Lac de Charmes. Assembled from 61 individual images, the selfie shows ...
Until now, it has been technically nearly impossible to rotate highly sensitive samples in all directions under a microscope without making contact. Researchers at the Karlsruhe Institute of Technology (KIT) have developed ...
Living organisms sustain themselves through intricate metabolic processes that continuously convert energy and materials into useful functions. Inspired by these biological systems, researchers are now engineering synthetic ...
A daring mission to lift NASA's sinking Neil Gehrels Swift Observatory is now one step closer to launch this June. On May 4, Katalyst Space Technologies completed environmental tests of its LINK robotic servicing spacecraft ...
Researchers have developed a sensor about the size of a grain of rice that can measure forces and twisting motions in all directions using light instead of traditional electronics. The new sensor could help robotic tools ...
The rotor blades that will carry NASA's next-generation helicopters to new Martian heights broke the sound barrier during March tests at NASA's Jet Propulsion Laboratory in Southern California. Data from the tests, which ...
The biological productivity of the Southern Ocean in the summertime is substantially greater than many previous estimates have suggested, according to new airborne research by the U.S. National Science Foundation National ...
