Hydrogen recombination found to be most plausible explanation for high levels of energy in stellar superflares
Although their primary purpose is to look for exoplanets, observatories like the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) have supplied a vast amount of data on stellar flares, detected with high-precision photometr.....»»
The first search for soft unclustered energy patterns in proton–proton collisions at 13TeV
A key objective of many physics studies is to experimentally observe exotic phenomena beyond the Standard Model (SM) that are predicted by theoretical models. These include hidden valley models, which predict the existence of a dark sector in which p.....»»
Deformable mirror technology takes laser welding and 3D printing to new heights
Yongcui Mi has developed a new technology that enables real-time shaping and control of laser beams for laser welding and directed energy deposition using laser and wire. The innovation is based on the same mirror technology used in advanced telescop.....»»
High velocity clouds comprise less of the Milky Way"s mass than thought, astronomers find
Sometimes in astronomy, a simple question has a difficult answer. One such question is this: what is the mass of our galaxy?.....»»
New technique for spotting Dyson rings unveiled
Dyson spheres and rings have always held a special fascination for me. The concept is simple: build a great big structure either as a sphere or ring to harness the energy from a star. Dyson rings are far more simple and feasible to construct and in a.....»»
Cosmic rays" vast energy traced to magnetic turbulence
Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments—like the roiling environments near black holes and neutron stars—have far more energy than the energetic particles that emerge from our sun. In fact, the particles.....»»
Predicting atomic structures proves useful in energy and sustainability
Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a new approach that combines generative artificial intelligence (AI) and first-principles simulations to predict three-dimensional atomic structures of highly complex materia.....»»
AI"s power demands driving toxic air pollution, study finds
Computer processing demands for artificial intelligence, or AI, are spurring increasing levels of deadly air pollution from power plants and backup diesel generators that continuously supply electricity to the fast-growing number of computer processi.....»»
EV charging infrastructure isn’t just for road trippers
Energy management will be key for electrified vehicle fleets. Although there's been a whole lot of pessimism recently, electric vehicle sales continue to grow, even if it is less.....»»

Surprising rumor says new HomePod will get high-quality OLED screen
South Korean press unexpectedly claims that Apple's anticipated new HomePod with a display will use high-quality OLED screens, all of which are to be manufactured in China.An artist's rendition of a HomePod with a displayThe much-rumored HomePod with.....»»
In vivo electrochemistry could provide early detection of high-altitude hypoxic brain injury
People who climb too fast or too high risk acute altitude sickness, which can lead to life-threatening hypoxic brain injury. By using in vivo electrochemistry, researchers have demonstrated that characteristic changes occur in the oxygen content of v.....»»
In at least one leading company, foreign-born talents are paid less
In the national debate over legal immigration, the H-1B visa program has acquired a special significance. Immigration skeptics contend that the program—reserved for high-skilled foreign nationals working in tech and other lucrative industries—mig.....»»
Less is more: Why an economical iridium catalyst works so well
Iridium-based catalysts are needed to produce hydrogen using water electrolysis. Now, a team at HZB has shown that the newly developed P2X catalyst, which requires only a quarter of the iridium, is as efficient and stable over time as the best commer.....»»
High heat is preferentially killing the young, not the old, research finds
Many recent studies assume that elderly people are at particular risk of dying from extreme heat as the planet warms. A new study of mortality in Mexico turns this assumption on its head: it shows that 75% of heat-related deaths are occurring among p.....»»
Lower-cost sodium-ion batteries are finally having their moment
World's largest battery maker touts second-generation sodium-ion battery. Sodium-ion batteries for electric vehicles and energy storage are moving toward the mainstream. Wider use.....»»
NASA flights map critical minerals from skies above western US
On a crystal-clear afternoon above a desert ghost town, a NASA aircraft scoured the ground for minerals. The plane, a high-altitude ER-2 research aircraft, had taken off early that morning from NASA's Armstrong Flight Research Center in Edwards, Cali.....»»
Copenhagen takes on its biggest climate threat—water
In low-lying Copenhagen where rising sea levels, groundwater and rainfall pose a risk to infrastructure, the Danish capital is trying to adapt and protect urban areas from climate change......»»
Solving waste plastic processing with heat circulation: Researchers develop large-scale pyrolysis process
Dr. Byungwook Hwang's research team from the CCS Research Department at the Korea Institute of Energy Research (KIER) has successfully developed a process that applies the circulating fluidized bed technology, commonly used in coal-fired power plant.....»»
3D models help researchers understand the climate impact of eddies
Mesoscale eddies are ocean vortices less than 100 kilometers in diameter that are responsible for the localized "weather" of the oceans. Because of the large amount of mass and energy movement associated with these currents, mesoscale eddies play an.....»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
