Lifestyle A wild blackbird being released. Credit: Christian Ziegler / Max Planck Institute of Animal Behavior Millions of birds migrate every year to escape winter, but spending time in a warmer climate does not save them energy, according to research by the Max Planck Institute of Animal Behavior (MPI-AB). Using miniaturized loggers implanted in wild blackbirds, scientists recorded detailed measurements of heart rate...

Technology tamfitronics A research team from South Korea’s Ulsan National Institute of Science & Technology (UNIST) has designed a wire-free transparent solar cell and module with all electrical contacts placed on the rear side. A 16 cm² module achieved a power conversion efficiency of 14.7% and successfully charged a smartphone using natural sunlight. September 16, 2024 Patrick JowettImage: UNISTResearchers from the School of Energy and Chemical Engineering at Ulsan National Institute of Science and Technology (UNIST) in South Korea have fabricated a new transparent solar cell and module.The team’s design features an all-back-contact (ABC) configuration, which places all electrical contacts on the rear side, creating a glass-like transparent crystalline silicon (c-Si) cell. They also developed Seamless Modularization technology to eliminate gaps between devices without using metal wires, resulting in a metal wire-free solar module.The ABC...

NASA Space Technology More than 100 scientists will participate in a field campaign involving a research vessel and two aircraft this month to verify the accuracy of data collected by NASA’s new PACE satellite: the Plankton, Aerosol, Cloud, ocean Ecosystem mission.The process of data validation includes researchers comparing PACE data with data collected by similar, Earth-based instruments to ensure the measurements match up.Since the mission’s Feb. 8, 2024 launch, scientists around the world have successfully completed several data validation campaigns; the September deployment — PACE-PAX — is its largest.From sea to sky to orbit, a range of vantage points allow NASA Earth scientists to collect different types of data to better understand our changing planet. Collecting them together, at the same place and the same time, is an important step used to verify the accuracy of...

NASA Space Technology NASA far side of the Moon - Space scientists are creating Matrix-like simulations to guide ... astronauts set to descend on the ancient sphere 700 days from now (Photo by NASA via Getty Images)Getty ImagesThe first American astronauts set to touch down on the Moon in the new millennium will not blast off for another 700 days, but now they can begin exploring potential landing sites by jacking into Matrix-style simulations of its cratered South Pole sector.Simultaneous revolutions in space-based imagers and laser scanners, and in virtual reality modelling toolkits, are giving rise to VR doubles of real-life lunar scenes that appear to be identical twins.“We are building very high resolution, photorealistic digital twins of potential Artemis III landing sites,” and then developing these into cutting-edge virtual replicas of...
