Phys.org / Antibiotics trigger bacterial teamwork, boosting survival through shared proteins
When bacteria are under antibiotic attack, it is not "every man for himself." Researchers at Baylor College of Medicine and colleagues from collaborating institutions have discovered that bacterial populations work as a team ...
Phys.org / AI reads 3D tooth microwear to reconstruct diets of early human ancestors
The study of dental microwear allows the analysis of the microscopic marks that foods leave on the surface of tooth enamel during mastication. In paleoanthropology, this methodology helps reconstruct the diet of fossil primates ...
Phys.org / Artificial 'leaf' powers wireless biomedical device
Plants convert light into energy efficiently through photosynthesis—an ability that scientists and engineers still struggle to match with electronic devices. Recently, researchers have looked beyond traditional semiconductor ...
Phys.org / Sponges may cut methylmercury contamination in marine food webs by more than 50%
Marine sponges may play an important, previously underestimated role in reducing methylmercury contamination in marine food webs. In a new modeling study, researchers at Helmholtz-Zentrum Hereon showed that sponges can significantly ...
Phys.org / Turtles may migrate using Earth's magnetic field
New research indicates that sea turtles seem to navigate across hundreds of miles of open ocean using Earth's magnetic field. Previous experimental studies suggested that sea turtles use geomagnetism to navigate, but this ...
Phys.org / Students' climate model of deadly July 4 Texas flooding suggests sea surface temperatures actually reduced rainfall
Last fall, the 12 students in the Jackson School of Geosciences' GEO 347G "Climate System Modeling" class set out to understand something that hit close to home: What were the climatological factors that made the July 4, ...
Phys.org / New electrocatalyst helps turn polluted water into fertilizer and polymers
A new electrochemical system simultaneously converts plant-derived materials and nitrate pollutants into valuable industrial chemicals. Developed by Tohoku University researchers, the system provides a more sustainable way ...
Phys.org / A thermodynamic approach to gravity could explain cosmic acceleration without dark energy
Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general relativity. This framework describes gravity as the curvature of spacetime, the invisible four-dimensional ...
Phys.org / Thirsty desert lizards inspire a new water-harvesting system
When the desert horned lizard (Phrynosoma platyrhinos) is thirsty, it cannot just lap up water or scoop it up like a bird because it lives in environments where water is extremely scarce. Typically, it's found in damp soil ...
Phys.org / Quantum waves reveal one-sided motion marking elusive critical states
Sound waves, light waves and other types of waves, generally spread freely through space and over time. In 1958, physicist Philip W. Anderson first described a phenomenon via which irregularities or other sources of disorder ...
Phys.org / Tiny water droplets transmutate aniline into pyridine in ambient and catalyst-free conditions
Aniline can now be transformed into pyridine without adding any catalysts, oxidants or toxic reagents. In a recent study published in the Journal of the American Chemical Society, researchers achieved skeletal editing, involving ...
Phys.org / Apes and humans have been sharing a laugh for 15 million years
Great apes may have been laughing with a similar rhythm to modern humans for at least 15 million years, a University of Warwick study reveals. The finding offers unexpected clues to how human speech evolved.
