Phys.org / White barn owls may use moonlight to startle prey
White barn owls are effective killing machines. They fly silently through the night air and swoop down on unsuspecting prey with their sharp talons. But they have something you would think goes against being a stealth predator: ...
Phys.org / Einstein Probe detects mysterious X-ray transient that doesn't fit any known class
Astronomers have reported the discovery of an unusual X-ray transient detected by the Einstein Probe that does not fit any known class of cosmic explosions. The paper presenting its multiwavelength analysis was published ...
Phys.org / Moose are native to Colorado, study shows
The modern Colorado moose is often considered just that: modern—brought to the state by wildlife officials in the late 1970s, preceded by very occasional reports of moose sightings in the 19th and early 20th centuries.
Phys.org / Brain growth may explain why birds lay outsized eggs compared with dinosaurs
A new study has uncovered a fundamental link between brain size and offspring size, helping to solve a long-standing evolutionary puzzle: Why do birds lay such disproportionately large eggs?
Phys.org / Oldest known asteroid impact on Earth dated to 3 billion years
Curtin University researchers have determined the most precise age yet for the oldest known impact crater on Earth, providing new insight into how meteorite strikes shaped the planet during its earliest history.
Phys.org / Hidden seismicity patterns before large earthquakes uncovered
When and where the next large earthquake will strike remains one of the most difficult questions in geoscience. Researchers from the GFZ Helmholtz Center for Geosciences led by Dr. Sadegh Karimpouli and Prof. Dr. Patricia ...
Phys.org / Physical pressure helps pathogenic P. aeruginosa survive antibiotic treatment
Pseudomonas aeruginosa is an opportunistic pathogen that can cause acute and chronic infections. Responsible for many hospital-acquired infections, it is also a major concern for people with cystic fibrosis, whose lungs are ...
Phys.org / Solid-state material turns visible light into high-energy UV at sunlight intensity, expanding solar energy potential
Two cups of warm water don't make one cup of boiling water. But in the quantum world, multiple low-energy photons can combine to produce a single, higher-energy photon.
Phys.org / Pterosaur wing tests suggest modern reconstructions miss major shape diversity
Pterosaurs, the first vertebrates to fly, would have had more diverse wing shapes than current scientific reconstructions suggest, according to new University of Bristol-led research. The study is published in the journal ...
Phys.org / Scientists create optical skyrmions using a two-century-old light phenomenon
Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, which are tiny, swirling ...
Phys.org / Pathway to high-fidelity quantum computing identified
Researchers from the University of Sydney, working with IBM, have identified and quantified important factors limiting the performance of quantum computers and demonstrated ways to overcome their impact.
Phys.org / People care more about being right than avoiding mistakes, study finds
Conventional wisdom says the best predictions are the ones that minimize mistakes, but new research suggests that is not necessarily how people see it. A study published in Management Science has found that when people make ...
