Two astronauts completed a 7-hour, 11-minute spacewalk to install a new solar array on the International Space Station, bringing NASA one step closer to a major power upgrade. Once the final array is installed on November 5, the station will have up to 30% more available power, supporting critical operations and its eventual controlled deorbit.
A collaborative research team led by Yasuhiro Kobori at Kobe University, together with researchers from Toho University, Saitama University, Nagoya Institute of Technology and the University of Freiburg, has identified a potential molecular mechanism that could enhance magnetic compass responses in cryptochrome, a blue-light-sensitive protein implicated in magnetoreception.
Earth is warming faster than ever recorded, with scientists detecting a major acceleration in global temperatures since around 2015. A new study reveals that the warming rate has surged to approximately 0.35°C per decade, nearly double the average pace observed from 1970 to 2015. After removing natural climate fluctuations, researchers confirmed the acceleration with more than 98% statistical confidence.
Astronomers have solved a 170-year-old planetary mystery in a nearby two-star system, discovering that a mysterious wobble was caused by stellar activity rather than a giant planet. Although Jupiter-sized worlds have been ruled out in key regions, smaller, potentially habitable planets could still be waiting to be discovered just 16 light-years from Earth.
As NASA and its partners prepare for longer human missions beyond Earth, University of Florida researchers are investigating a challenge that could affect astronauts' ability to grow fresh food in space: plant disease.
A U.N. report finds that 252 million hectares (ha) (623 million acres) across 149 countries are being restored, creating more than 1 million green jobs—the largest documented global restoration effort to date.
A newly published study advances our knowledge of how microplastics may age in the environment and whether they stick to other contaminants as they do so. Microplastics (MPs) are tiny plastic pieces that measure less than 5 millimeters (about 0.2 inches) in length. The study looked at the aging of MPs made of three common polymer chemicals—polyethylene, polyethylene terephthalate and polypropylene—to see if they changed as they aged and how that affected nearby contaminants.
Scientists have discovered that three bizarre deep-sea fish that look exactly like seahorses actually belong to a separate evolutionary group, proving that nature created the same unusual body shape more than once. Nicknamed "sea muppets," these elusive creatures are known from just seven specimens, and no one has ever seen one alive.
A handful of soil holds a crowded world of bacteria, fungi and other organisms. Scientists can collect their DNA, but much of it remains difficult to identify. Now, researchers at the Hebrew University of Jerusalem and partner institutions have developed an artificial intelligence tool that helps make sense of this genetic puzzle.
A University of Alicante (UA) study of 325 fiction series released in Spain between 2020 and 2024 has concluded that video-on-demand (VOD) platforms have not replaced traditional television. Instead, the two distribution models are developing new ways of collaborating and sharing content.
