Telescope Array detects second-highest-energy cosmic ray everIn 1991, the University of Utah Fly's Eye experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray's energy shocked astrophysicists. Nothing in our galaxy had the power to produce it, and the particle had more energy than was theoretically possible for cosmic rays traveling to Earth from other galaxies. Simply put, the particle should not exist. | |
Study examines how massive 2022 eruption changed stratosphere chemistry and dynamicsWhen the Hunga Tonga-Hunga Ha'apai volcano erupted on January 15, 2022 in the South Pacific, it produced a shock wave felt around the world and triggered tsunamis in Tonga, Fiji, New Zealand, Japan, Chile, Peru and the United States. | |
Physicists find evidence of exotic charge transport in quantum materialTrue to form, a "strange metal" quantum material proved strangely quiet in recent quantum noise experiments at Rice University. Published this week in Science, the measurements of quantum charge fluctuations known as "shot noise" provide the first direct evidence that electricity seems to flow through strange metals in an unusual liquidlike form that cannot be readily explained in terms of quantized packets of charge known as quasiparticles. | |
New constraints on the presence of ultralight dark matter in the Milky WayDark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional experimental methods. | |
Archaeologists uncover Europe's hidden Bronze Age megastructuresArchaeologists from University College Dublin, working with colleagues from Serbia and Slovenia, have uncovered a previously unknown network of massive sites in the heart of Europe that could explain the emergence of the continent's Bronze Age megaforts—the largest prehistoric constructions seen prior to the Iron Age. | |
Physiological and archaeological evidence rewrites assumptions about a gendered division of labor in prehistoric timesPrehistoric men hunted; prehistoric women gathered. At least this is the standard narrative written by and about men to the exclusion of women. | |
Global view of Io's volcanic activity suggests that tidal heating is concentrated within its upper mantleA team of volcanologists and planetary scientists from NASA's Jet Propulsion Laboratory, California Institute of Technology, the University of Arizona, and Arizona State University has found via study of a newly created global view of Io's volcanic activity that its tidal heating is likely concentrated within its upper mantle. In their study, reported in the journal Nature Astronomy, the group analyzed data from sensors measuring heat emission from the closest of Jupiter's innermost moons. | |
Research challenges widespread belief that honeybees naturally insulate their colonies against coldA Leeds researcher is keen to help beekeepers shape their practices following his study which appears to disprove the widespread belief that honeybees naturally insulate their colonies against the cold. His findings suggest that the creatures are potentially being subjected to thermally-induced stress. | |
The bilingual brain may be better at ignoring irrelevant informationPeople who speak two languages may be better at shifting their attention from one thing to another compared to those who speak one, according to a study published this month in the journal Bilingualism: Language and Cognition. | |
World's richest 1% emit as much carbon as bottom two-thirds: reportThe richest one percent of the global population are responsible for the same amount of carbon emissions as the world's poorest two-thirds, or five billion people, according to an analysis published Sunday by the nonprofit Oxfam International. | |
Residential solar power saves less energy than expectedImagine a household that consumes 1,000 kilowatt hours of energy per month. Then they install solar panels on their roof that generate 500 kilowatt hours of electricity per month on average. How much should their consumption of electricity drawn from the power grid decline after they install solar? Five hundred kilowatt hours is the expectation, but in reality, it's less than that for most people. Now, they're consuming more than 1,000 kilowatt hours per month. | |
AI finds formula for how to predict monster waves by using 700 years' worth of dataLong considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs. Using 700 years' worth of wave data from more than a billion waves, scientists at the University of Copenhagen and University of Victoria have used artificial intelligence to find a formula for how to predict the occurrence of these maritime monsters. The new knowledge can make shipping safer. | |
Bacteria store 'memories' and pass them on for generations, study findsScientists have discovered that bacteria can create something like memories about when to form strategies that can cause dangerous infections in people, such as resistance to antibiotics and bacterial swarms when millions of bacteria come together on a single surface. The discovery—which has potential applications for preventing and combatting bacterial infections and addressing antibiotic-resistant bacteria—relates to a common chemical element bacterial cells can use to form and pass along these memories to their progeny over later generations. | |
'Triple star' discovery could revolutionize understanding of stellar evolutionA ground-breaking new discovery by University of Leeds scientists could transform the way astronomers understand some of the biggest and most common stars in the universe. The paper, "Gaia uncovers difference in B and Be star binarity at small scales: evidence for mass transfer causing the Be phenomenon," is published in the journal Monthly Notices of the Royal Astronomical Society. | |
Research reveals rare metal could offer revolutionary switch for future quantum devicesQuantum scientists have discovered a rare phenomenon that could hold the key to creating a 'perfect switch' in quantum devices which flips between being an insulator and a superconductor. | |
AI system self-organizes to develop features of brains of complex organismsCambridge scientists have shown that placing physical constraints on an artificially-intelligent system—in much the same way that the human brain has to develop and operate within physical and biological constraints—allows it to develop features of the brains of complex organisms in order to solve tasks. | |
New carbon material sets energy-storage record, likely to advance supercapacitorsGuided by machine learning, chemists at the Department of Energy's Oak Ridge National Laboratory designed a record-setting carbonaceous supercapacitor material that stores four times more energy than the best commercial material. A supercapacitor made with the new material could store more energy—improving regenerative brakes, power electronics and auxiliary power supplies. | |
Fossil unearthed in Mongolia's Gobi Desert suggests some dinosaurs slept in same position as modern birdsA team of paleontologists and biologists from Hokkaido University, Hokkaido University Museum, North Carolina State University and the Mongolian Academy of Sciences, has uncovered a previously unknown species of dinosaur that appears to have slept in the same position as modern birds. | |
Scientists finally succeed in growing dolomite in the lab by dissolving structural defects during growthFor 200 years, scientists have failed to grow a common mineral in the laboratory under the conditions believed to have formed it naturally. Now, a team of researchers from the University of Michigan and Hokkaido University in Sapporo, Japan have finally succeeded, thanks to a new theory developed from atomic simulations. | |
Higher levels of financial optimism associated with lower levels of cognitive abilityA behavioral economist at the University of Bath in the U.K. has found evidence linking higher levels of unwarranted financial optimism with lower levels of cognitive ability. In his study, published in the journal Personality and Social Psychology Bulletin, Chris Dawson surveyed thousands of people in the U.K. about their economic outlook and compared their responses with their true financial outlook.
