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 / 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 / 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 / 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 / Trios of quantum particles form checkerboard layouts when particle density hits sweet spot
Trions form when three particles, like quarks or electrons, come together. This formation occurs in quantum particles in nuclear physics, semiconductors and magnets, and understanding its behavior can be challenging. Rice ...
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 ...
Dialog / Miniature satellite tags reveal diving behavior of juvenile sea turtles
Until recently, researchers were unable to conduct satellite-tracking studies on juvenile turtles because of their small body sizes and immediate dispersal into the ocean, leaving this period of their lives enigmatic and ...
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 / Megacluster of bacterial genes reveals four antibiotics that jointly starve rivals of biotin
Researchers at McMaster University have discovered what they describe as a "megacluster" of genes in Streptomyces bacteria that produces four antibiotics that work together to stop rival bacteria.
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 / This single well-known and widespread butterfly is actually three species in disguise
The tropical rainforests of Central and South America are among the most biodiverse places on Earth. Costa Rica alone is home to half a million species, five times more than exist in the entire country of Canada, despite ...
Phys.org / Growing up gets less scary with time, research finds
As young adults, many millennials feared growing up more than past generations. But they've come around to it as they age, research published in the journal Developmental Psychology has found.
