Phys.org / Mathematical model shows how birds create a synchronized dawn chorus
Every morning, groups of birds start singing and chirping around the same time, typically when the sun starts rising. While zoologists have been studying this collective bird behavior, called the dawn chorus, for decades, ...
Phys.org / Arctic fossil abandoned in 1948 proves to be record-size Triassic hunter
Nearly 80 years ago, a British expedition discovered the battered remains of a giant fossil on the peak of an Arctic island. Unable to take it with them, they snapped some pictures, took some bones and left the fossil to ...
Phys.org / A new category of heat waves is melting western US snowpack faster
Heat waves are not all created equal. While some bring dry heat that rapidly dries out crops, others carry a lot of moisture that can prevent sweat from evaporating off the skin. In new research published in the journal Science ...
Phys.org / Long-sought Zhang-Rice singlet visualized directly in cuprate superconductor
Superconductors are materials that conduct electricity with zero electrical resistance below specific temperatures. Most of these materials become superconducting at very low temperatures, but some also exhibit superconductivity ...
Phys.org / Engineered microbe speeds CO₂ capture and recovers critical metals
A genetically engineered bacterium can rapidly break down one of Earth's most abundant minerals, opening a promising new pathway for simultaneously removing carbon dioxide from the atmosphere and recovering critical elements ...
Dialog / Bound gravitational waves inspired by photonic systems
When one mentions "waves," we immediately think of a perturbation that propagates. This applies to waves on the shore, sound waves in the air or electromagnetic waves that we use to transmit information via optical fibers. ...
Phys.org / Genome study reveals centromeres as one of the fastest-changing regions in human DNA
A centromere is a specific region on a chromosome that ensures that, when a cell divides, the chromosome separates accurately so each new cell receives the correct amount of genetic material. Despite their essential role, ...
Phys.org / Recyclable glue bonds underwater in seconds and holds for years
Most glues need a dry surface to stick properly. Bonding materials underwater is challenging because water forms a thin film on any surface, so instead of an adhesive touching a material directly, it touches a layer of water, ...
Medical Xpress / Two devices in one: Metasurface could bring medical imaging to smaller sensors
Researchers have developed a technology for building more compact point-of-care medical imaging devices by creating a material that acts as two devices in one.
Phys.org / Firefighters battle second day of blaze on Greek island
Firefighters battled for a second day Sunday to contain a forest fire on the Greek Aegean island of Skyros, as the local mayor voiced hope it could soon be brought under control.
Medical Xpress / A new target in the gut for reducing Alzheimer's risk
A compound produced by bacteria in many people's digestive tracts increases the risk of developing Alzheimer's disease and speeds cognitive decline in dementia patients, making it a potential target for a treatment that could ...
Science X / Tropical cooling points to a world 5.4°C colder at the Ice Age peak
During the Last Glacial Maximum, tropical regions with lush vegetation would have looked completely different. The last Ice Age reached its peak about 20,000–21,000 years ago, and massive ice sheets covered parts of North ...
