Phys.org / Fossils upend catastrophist narrative that flowering plants flourished only after dinosaur extinction
A unique cache of plant fossils from volcanic deposits in New Mexico contradicts the common narrative that flowering plants were minor players in Earth's forests until dinosaurs disappeared 66 million years ago.
Phys.org / Plankton-linked vapors could speed cloud seed formation over cold oceans
For nearly 50 years, scientists have suspected that microscopic marine plankton play a role in cloud formation over the oceans. Now, an experiment led by the University of Helsinki suggests that it may be more important than ...
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 / Fossil fish tooth chemistry uncovers Southern Hemisphere role in Earth's ice age shift
To understand where Earth might be headed, it's important to know where it has been. Throughout its existence, especially over the past couple of million years, Earth has experienced periodic cold and warm intervals, known ...
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 / Check politics at the door? Not at many workplaces, researcher says
When people think of workplace segregation, they usually think of race or gender. Yet Americans are also sorted at work by something employers rarely measure: how they vote.
Phys.org / Scientists develop predictive roadmap to boost performance in next-gen spintronics
Chiral 2D metal halide perovskites (MHPs) are among the most promising materials for future technologies that exploit the spin of electrons in spin-based optoelectronics, or spintronics, but getting them to perform consistently ...
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 / New insight into how cells move copper out of the mitochondrial matrix could guide novel treatments
Copper is essential for life. Our cells need the metal to make energy and stay healthy, but if it is in the wrong place or present in excess, copper can be deadly. Texas A&M AgriLife Research scientists have identified a ...
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 / Shorter front-leg strides can be an early warning sign of dementia in senior dogs
Scientists have shown that the stride length of the front legs (but not the hind legs) of senior and geriatric dogs decreases as their cognitive performance worsens. In contrast, chronological age itself was a poor predictor ...
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 ...
