Phys.org / Irrigation gaps in weather models could skew air quality forecasts, study finds
Outdoor air pollution is estimated to contribute to more than 100,000 premature deaths in the United States each year, according to the National Weather Service. Accurate air quality forecasts—designed to protect public ...
Phys.org / Simulation makes it possible to study movements of cell's largest protein complexes without supercomputers
Large protein machines in the body carry out many of the cell's most essential tasks, from energy production to the regulation of signal transmission. Although they can now be imaged in great detail using cryo-electron microscopy, ...
Phys.org / Influenza's molecular theft caught in action—how the virus steals the cap of host RNA in order to replicate
The cold season is in full swing, throats are scratchy and noses are running. We feel ill and hope it is not the flu. The influenza virus continues to pose a threat to our health. It triggers seasonal epidemics and, from ...
Phys.org / Satellite study of 2.2 million thunderstorms shows how to predict their formation
People may be frustrated by the lack of detail when weather forecasters say, "There will be thunderstorms popping up, but we don't know where." Now a key finding in a study by the UK Centre for Ecology & Hydrology (UKCEH), ...
Phys.org / New 4D-STEM method isolates atomic structures from clustered nanocrystals
Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new way to determine atomic structures from nanocrystals previously considered unusable, a breakthrough that could ...
Phys.org / Drinking water at risk long after wildfires, study warns
Canada's drinking water can remain at risk long after wildfires burn out, according to a UBC-led global review that found water-quality impacts often emerge months or years later—not just immediately after a fire. Researchers ...
Phys.org / Study reveals reported crop yield gains from breeding may be overstated
A new study suggests that decades of reported gains in crop yields from plant breeding may be significantly overstated, challenging a common method used worldwide to measure genetic progress. The international research team ...
Phys.org / The forest is our pantry: Alaska national forests support abundant wild foods
Rural communities bordering the Tongass National Forest harvest more than 4.5 million pounds of wild food per year, including 100 different species that our public lands help support. Just how much food is this? An average ...
Phys.org / Nitrous oxide, a product of fertilizer use, may harm some soil bacteria
Plant growth is supported by millions of tiny soil microbes competing and cooperating with each other as they perform important roles at the plant root, including improving access to nutrients and protecting against pathogens. ...
Phys.org / Just three molecules can launch gene-silencing condensates in stem cells
A new study has uncovered how an exceptionally scarce protein can orchestrate the assembly of large-scale gene-silencing structures inside cells, and what happens when that process breaks down. The findings, published today ...
Phys.org / Drill core reveals asynchronous land–ocean responses to ancient ocean anoxia
Earth experienced a period of intense, large-scale volcanism during the early Aptian. Around that time, it also experienced widespread ocean deoxygenation during the Oceanic Anoxic Event 1a (OAE1a) as well as the onset of ...
Phys.org / Vocal analysis and AI uncover two new Amazon antbirds in five-species complex
Scientists have discovered that a widely recognized Amazonian antbird is not one, but five distinct species—including two completely new to science. This revelation of hidden biodiversity was achieved by integrating artificial ...
