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 / 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 / '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 / 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 ...
Phys.org / 'Uncanny valley' effect observed in macaques through 3D animated monkey avatars
A new tool that allows researchers to create realistic full-body animations of monkeys has provided the first evidence that nonhuman primates experience the "uncanny valley" phenomenon for body avatars, according to a study ...
Phys.org / Europe's last pagan state was already diverse: Medieval Vilnius drew migrants from Christian lands
Lithuania was famously the final pagan state in Europe. While the rest of the continent converted to Christianity, Lithuania remained officially pagan until Catholicism was adopted in AD 1387. Despite this, the extent to ...
Phys.org / Engineers find a precise way to grow artificial blood vessels
Tissue engineers are finding ways to grow living organs and tissues from cells, with the aim of replacing diseased and damaged counterparts in the body. Scientists have successfully grown artificial muscles, livers, kidneys, ...
