Phys.org / What really controls water chemistry in nanoscale spaces
Water is the most studied molecule on Earth, yet a surprisingly basic question has gone unanswered for decades: When water is squeezed into gaps just a few molecules wide—as happens inside nanoscale pores, membranes and biological ...
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 / 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 / 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 / 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.
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 / 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 / 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 ...
