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 / 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 / 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 / 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 / Australia's under-16 social media ban shows little early effect on teen use: Research
Australia's social media ban for under-16s has had little impact on teenagers' scrolling habits, researchers said Thursday in one of the first evaluations of the world-leading measures.
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 / Self-propelled actin filaments may explain how cells change shape spontaneously
Cells can spontaneously change shape even without external signals, but the underlying mechanisms behind this form of self-organization have remained unclear. Now, researchers from Japan have discovered self-propelled treadmilling ...
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.
