A sunlight-harvesting technology created by researchers in Los Alamos and Italy could turn any window into a solar energy source. The technology is based on tiny nanoparticles known as quantum dots, which can absorb sunlight as it filters through a window. The light is then emitted from the dots at the infrared wavelength and is guided to the edge of the window, where solar cells transform it into useable energy. Victor Klimov, lead researcher on the project at the Center for Advanced Solar Photophysics (CASP) of Los Alamos, said “Using this design, a nearly transparent window becomes an electrical generator, one that can power your room’s air conditioner on a hot day or a heater on a cold one.” Read the rest of Quantum dot solar windows could turn any window into a power source

Wild sheep shed their wool each year, but Merino sheep have been bred specifically to keep on growing until they’re shorn – so we can use their wool. The now-famous Chris, a sheep in Australia who somehow wandered off from his flock into the wild and evaded shearing for up to six years, according to expert estimates, was on death’s doorstep when a hiker discovered him outside Canberra. His wool had grown so big, he was susceptible to parasites and infection and at risk of falling over. If that had happened, he wouldn’t have been able to get back up, making him fair game for wild animals. Fearing the worst, the hiker immediately alerted authorities, and Tammy Ven Dange from the Royal Society for the Prevention of Cruelty to Animals posted an urgent SOS tweet. “Help! @rspcaact needs help from a sheerer immediately to hopefully save this sheep we just rescued!” she wrote. Ian Elkins, a renowned celebrity shearer, volunteered his services. Read the rest of Chris the overgrown sheep spared certain death by celebrity Aussie shearer Ian Elkins
