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 / Hidden electric space waves are quietly cleaning Earth's 'killer' electrons
High above our heads, a silent battle is unfolding within Earth's magnetic shield. For decades, scientists have tracked "killer electrons"—ultrafast particles capable of piercing satellite armor and endangering astronauts ...
Phys.org / New JWST images of abnormally well-developed galaxy cluster open up the 'cosmic noon' frontier
A stunningly concentrated and hefty galaxy cluster, from a time in the universe's history when such massive structures aren't expected to have fully formed yet, is challenging cosmic evolution theories. Across a series of ...
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 ...
Science X / Could less caffeine be the smarter performance enhancer? Scientists find a surprising sweet spot
Think of an athlete eyeing the finish line—could a single shot of caffeine be the difference between a podium finish and a personal best? For decades, runners and cyclists have treated the stimulant as a near-magical performance ...
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.
Medical Xpress / Keeping HIV at bay: New approach explores broadly neutralizing antibodies to treat infants
In the ongoing effort to find new therapeutics for infants born infected with the human immunodeficiency virus, an international team of investigators has discovered that babies can tolerate treatment with anti-HIV antibodies.
Phys.org / Newly described Australian ballista spider builds a spring-loaded snare to catch a single ant species
An international team of researchers has discovered a remarkable new spider species in the rainforest of North Queensland that spins an ingenious and powerful spring-actuated snare to catch a single species of ant—one ant ...
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 / 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 / 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 / How languages recycle parts of words to avoid confusion
Many languages recycle words, giving them different meanings. For example, in English, "run" can mean to move quickly but also to manage something, like "run a company." In Spanish, "lengua" is both the word for tongue and ...
