Phys.org / Copper's oxygen-rich early oxidation layer could inform catalyst design and nuclear waste storage
Copper roofs lose their reddish color over time because a pale green layer of copper oxide forms on their surface, protecting the roof from further corrosion for many years. But what exactly happens during the first steps ...
Phys.org / Scientists discover the key ingredients that make birdsong pretty
What makes birdsong beautiful? Answering this question could help us understand how soundscapes make the natural world relaxing for humans, opening the door to improving parks, upgrading the design of stressful places like ...
Phys.org / Wrinkled or smooth? Cell growth mechanics determine shape of plant organs
When inner and outer cell layers of sepals—the leaf-like plant organs that cover and protect the flower bud before it opens—all grow upward, the organs stay smooth and uniformly stiff, which is optimal for the plant, according ...
Phys.org / Young sunlike system reveals comets may carry water toward forming planets
Astronomers at Lund University in Sweden have found evidence of exocomets—comets in other solar systems—orbiting a young star similar to our sun. The observations point to a possible mechanism for how water might be transported ...
Phys.org / How stressed cells put the brakes on protein 'shipping'
Cells synthesize proteins in the endoplasmic reticulum (ER), and these proteins are transported to the Golgi apparatus for distribution to their ultimate destinations inside and outside the cell. The structures that transport ...
Phys.org / Surf's up: How the seafloor shapes breaking waves
A new study led by surfing scientists at the Scripps Institution of Oceanography at UC San Diego revealed the physical relationships underlying a pattern familiar to generations of surfers.
Phys.org / NASA rocket takes first multi-point look inside radio-disrupting clouds
High above Earth, thin veils of metallic haze drift through the edge of space. Known as sporadic E layers, these high-altitude "clouds" form from the vaporized dust of burned-up meteors, earning their name from the unpredictable ...
Phys.org / First DDT, now the flu: Peregrine falcons in San Francisco Bay Area hit hard by H5N1 variant
Highly pathogenic avian influenza (HPAI) featured prominently in the news during 2020 as it took the lives of millions of birds across the globe. While the worst seems to be behind us, population-level effects are just now ...
Medical Xpress / GLP-1 treatment late in life extends lifespan in animal model
A study published in Nature has shown that the GLP-1 drug semaglutide extended the lifespan of older, healthy mice by tempering the detrimental effects of aging. Researchers at the University of California, Berkeley, directly ...
Phys.org / Pigment found in beets linked to plants' adaptation to harsh environments
The pigments that give beets their red color may have helped a major group of flowering plants repeatedly adapt to dry environments, setting the stage for the evolution of traits that allowed plants to adapt to some of the ...
Medical Xpress / Routine clinical data help AI predict rapid Parkinson's decline three to five years in advance
For patients diagnosed with Parkinson's disease, one of the greatest uncertainties is what comes next. Some people experience relatively mild symptoms for years. Others face a much steeper course marked by worsening movement ...
Phys.org / First measurement of low-energy solar neutrinos scattering off electrons
Every second, tens of billions of neutrinos produced by nuclear fusion in the sun pass through every square centimeter of Earth—and through our bodies—almost without interacting. Although they are among the most abundant ...
