Scientists have found a way to 'tattoo' tardigrades
If you haven't heard of a tardigrade before, prepare to be wowed. These clumsy, eight-legged creatures, nicknamed water bears, are about half a millimeter long and can survive practically anything: freezing temperatures, near starvation, high pressure, radiation exposure, outer space and more. Researchers took advantage of the tardigrade's nearly indestructible nature and gave the critters […]
New electronic 'skin' could enable lightweight night-vision glasses
Engineers developed a technique to grow and peel ultrathin 'skins' of electronic material that could be used in applications such as night-vision eyewear and autonomous driving in foggy conditions.
A cool fix for hot chips: Advanced thermal management technology for electronic devices
Researchers have demonstrated a significant performance increase in cooling technology for high-power electronic devices. They designed novel capillary geometries that push the boundaries of thermal transfer efficiency. This study could play a crucial role in the development of next-generation technology.
Farm robot autonomously navigates, harvests among raised beds
A researcher has developed an autonomous driving algorithm for agricultural robots used for greenhouse cultivation and other farm work.
Study finds dramatic boost in air quality from electrifying railways
Switching from diesel to electric trains dramatically improved the air quality aboard the San Francisco Bay Area's Caltrain commuter rail line, reducing riders' exposure to the carcinogen black carbon by an average of 89%, finds a new study. The electrification of the system also significantly reduced the ambient black carbon concentrations within and around the […]
Cooler faster better: Engineers uncover a new way to stop electronics from overheating
Engineers discovered a way to move heat ultrafast using crystal waves, offering a breakthrough in cooling advanced electronics.
