Phys.org / Decades-long dataset shows which orcas are most at home in Puget Sound
Data spanning nearly half a century shows that endangered southern resident killer whales are spending less time in inland waters, whereas their larger cousins, Bigg's killer whales, are increasingly present in Puget Sound.
Phys.org / Oysters used as living labs reveal unexpected stability in ocean virus populations
Oysters filter seawater for food. In the process, they concentrate a wide variety of microorganisms from their environment—including bacteria and viruses—into a tiny space.
Phys.org / Axolotl-inspired skin matrix may help heal wounds with less scarring
Researchers in Taiwan have developed a cell-free extracellular matrix material from axolotl skin that helped mouse burn wounds close faster and show signs of reduced fibrotic scarring. The findings suggest that one of nature's ...
Phys.org / Pop song lyrics grew more self-focused in the US and Germany over 50 years, research reveals
Over five decades, popular songs in the U.S. and Germany have become more self-focused—as indicated by the use of pronouns such as "I," "me" and "mine"—while no such trend was seen for the most popular songs in Japan and ...
Phys.org / New giant wormlion fly species identified on the southern slopes of the Himalayas
An enigmatic new species of wormlion fly, whose larvae construct clever pitfall traps to capture prey, has been revealed in a study led by researchers at Dali University in China.
Phys.org / Lavatory shaft reveals the cost of 17th‑century vanity in Germany
Four goose skulls were pulled from a former toilet shaft in Brandenburg, Germany, each of them riddled with strange holes. As it turns out, these holes were the telltale signs of fancy feathered crests, making them the first ...
Phys.org / How long can plants survive on Earth? New model suggests up to 2 billion more years
Vegetarians need not worry yet—plants will be on Earth for a long time to come. But not forever. The sun will ultimately determine the long-term existence of life on Earth. Its total energy output, called luminosity, has ...
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 / 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 / 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 / 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 / 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?
