Phys.org / What happens inside a wildfire? A Ph.D. student is finding out
What happens during a wildfire? The short answer is: much more than we know. As wildfires burn through trees, grasses and other vegetation, heat from the flames sets off thousands of chemical reactions at once. Molecules ...
Phys.org / Ball milling enhances the antiviral activity of inexpensive inorganic materials
Since the COVID-19 pandemic, developing surfaces that can inactivate viruses upon contact has become an important goal in public health care. Ideally, such surfaces would work on their own without requiring chemical disinfectants, ...
Phys.org / Assembly of giant wild sunflower family genomes unlocks potential for new perennial crops
The Land Institute and HudsonAlpha Institute for Biotechnology, in collaboration with key partners, have assembled the first chromosome-scale, haplotype-phased genomes for Silphium integrifolium (rosinweed, silflower) and ...
Dialog / Blood-clotting protein may be SARS-CoV-2's hidden accomplice, helping it hide from antibodies and reach blood vessels
Fibrinogen, the abundant plasma protein best known for forming blood clots, may play a second and far less benign role during SARS-CoV-2 infection: acting as a molecular bridge that simultaneously hides the virus from neutralizing ...
Phys.org / New study reveals how space rocks become meteorites
What happens to a space rock as it falls through Earth's atmosphere and becomes a meteorite? By studying 75 meteorite falls captured on video and in photographs, researchers identified seven distinct phases in the journey ...
Phys.org / One step closer to the ideal glass—simulations reveal hidden order at absolute zero
In the physical sense, glass is not limited to familiar window glass; it forms whenever a liquid is cooled so quickly that it cannot crystallize. As a result, glass has an amorphous structure—that is, its "building blocks" ...
Phys.org / Mule helps scientists build the clearest horse and donkey genomes yet
A mule has helped researchers build the most complete reference genomes to date for horses and donkeys, giving scientists access to complex regions of DNA that earlier versions could not fully capture.
Phys.org / A 2-degree twist creates a nanoscale grid that traps light energy at room temperature
You may have once tried taking a close-up picture of a computer screen and noticed a wavy, rippling effect. This optical effect occurs whenever two fine, repeating grids overlap and slightly misalign, such as when the pixel ...
Phys.org / Mystery statue unearthed at Sardis archaeological dig
Researchers with the long-running Harvard–Cornell Archaeological Exploration of Sardis have unearthed a larger-than-life statue estimated to be nearly 2,500 years old.
Phys.org / Mechanical memory helps explain how cells adapt their movement to changing environments
Cells in our bodies squeeze through dense tissue channels, thread past neighboring cells and navigate every nook and cranny within the extracellular matrix—the mesh-like network that surrounds and supports cells. How well ...
Phys.org / Corners in focus: Metasurface enables motion tracking without digital image processing
A research team at City University of Hong Kong (CityUHK) has developed a new optical corner-detection imaging method that uses azimuthal Hilbert transform metasurfaces and is designed to work as a universal framework. The ...
Phys.org / How to CT scan a 400-pound crocodile
At 61, Bill had begun showing changes in his health—decreased appetite, weight loss and abdominal bloating. But his bloodwork was normal, leaving the cause of his symptoms unknown. The next step was clear: Bill should get ...
