Dialog / Ocean acidification emerging as a planetary signal linking today's carbon emissions to Earth's deep-time memory
When most people hear the phrase "ocean acidification," they think of coral reefs, shellfish or declining fisheries. Those concerns are real. But while working on our recent research, I found myself asking a different question: ...
Phys.org / World-first neutron lens brings sharp focus to structures inside materials and objects
Researchers at Paul Scherrer Institute (PSI) have developed the world's first achromatic lens for neutron imaging. The lens overcomes a longstanding obstacle in the field: focusing neutrons of different wavelengths well enough ...
Phys.org / Astronomers uncover the earliest known signs of galaxy-building in action
Astronomers at Durham University have made a major advance in understanding how galaxies formed and evolved in the early universe. Using powerful new observations, the team discovered the most distant example ever found of ...
Phys.org / Low-altitude flights reveal Amazon methane emissions far above climate model estimates
Methane (CH4) is a potent greenhouse gas whose concentration in the atmosphere has risen sharply in recent decades. Wetlands are the largest natural source of methane to the atmosphere, but large uncertainties remain about ...
Phys.org / Haven or trap? Study finds sinkholes protect endangered tree at evolutionary cost
Are giant sinkholes in China's karst mountains havens or traps for the rare plants that inhabit them? A new study finds they are both—offering refuge from heat and drought while gradually eroding the evolutionary potential ...
Phys.org / Ancient Roman farm women made wine, oil and profits. Historians dismissed them as 'housekeepers'
Female farm managers are hidden in plain sight in ancient Roman texts, mentioned in laws, literature and grave inscriptions across five centuries. Modern historians have generally assumed they were housekeepers, in charge ...
Phys.org / New technique for building ultra-thin material stacks promises quantum breakthrough
Scientists have unveiled a new fabrication technique for the ultra-clean manufacturing of 2D heterostructures—materials just a few atoms thick—that could be used in quantum technology and electronics. Experts from Southampton ...
Phys.org / Mystery of why some toads survive deadly fungus revealed
The mystery of why some amphibian populations recover following outbreaks of a deadly fungus has been solved in a new study led by University College London (UCL), ZSL and Imperial College London.
Phys.org / 'Amazing moths': Study pinpoints insect habitat that draws grizzlies to glacier peaks
When grizzly bears clamber onto the talus slopes high in Glacier National Park, they're searching for an abundant, fatty meal: army cutworm moths. The inch-long (2.5-centimeter-long) moths hatch on the Great Plains and fly ...
Phys.org / Study reveals Hawaiian hotspot is getting hotter
Contrary to conventional geological thinking, the Hawaiian mantle plume has gotten hotter by about 250°C (480°F) over the past 47 million years. This discovery, led by Earth scientists at the University of Hawai'i at Mānoa, ...
Phys.org / How supermassive black holes feed themselves
Astronomers are closer to solving the mystery of how supermassive black holes feed themselves thanks to new images from the James Webb Space Telescope, or JWST. The images provide the clearest view ever seen of gaseous filaments ...
Phys.org / Researchers define new frontier in quantum materials
Researchers at City College of New York physicist Vinod M. Menon's Laboratory for Nano and Micro Photonics (LaNMP) have outlined an emerging frontier in quantum materials: atomically thin systems in which light, magnetism ...
