Phys.org / How fishing may be changing one fish species at the molecular level
The pearly razorfish (Xyrichtys novacula) is a small marine animal that lives in sandy coastal waters and feeds on creatures like shrimp. Known locally in Spain's Balearic Islands as raors, it is a popular dish in many homes ...
Phys.org / Why and how birdsong differs across the world—and the eight motifs that tie them together
Birdsong carries meaning across open space, helping birds attract mates, defend territory and communicate with rivals. While there has been much research into the use of birdsong across species, researchers have lacked a ...
Phys.org / Why evolution never produced mammal teeth that slice and crush equally well
Evolution is all about trade-offs. Traits that may be beneficial in one situation may backfire in another. Over millions of years, species can become specialized for one way of living rather than being equally good at everything. ...
Phys.org / Astronomers catch massive galaxy assembling piece by piece 1.2 billion years after Big Bang
Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe's largest galaxies formed. The paper outlining the ...
Phys.org / Prize honors discovery of altermagnetism as a third fundamental class of magnetism
One of Europe's highest distinctions in condensed matter physics has been awarded for a discovery that is reshaping our understanding of magnetism: The 2026 Europhysics Prize of the European Physical Society (EPS) Condensed ...
Phys.org / Scientists turn modern biobanks into a new window on human evolution
For more than a century, scientists have sought to reconstruct human evolution using diverse lines of evidence, including fossils, genetic variation across populations and ancient DNA. Building on these approaches, researchers ...
Medical Xpress / Rates of opioid toxicity deaths highest among construction and trades workers, study finds
Between 2018 and 2024, those who worked in construction and trades made up approximately one-third of deaths from opioid toxicity in Ontario where occupation was known, according to a report released this week by the Ontario ...
Phys.org / Long-lived ytterbium states could sharpen quantum computing and atomic clocks
Researchers from the University of Amsterdam and the University of New South Wales have answered a question that has been around for decades: whether ions of the metal ytterbium can enter certain long-lived, nearly stable ...
Phys.org / Plumage reflectance framework offers new insight into how birds evolved heat-controlling feathers
Birds can inhabit various environments with different climates and temperatures, ranging from cold polar regions to scorching hot deserts. To survive and thrive in these very different environments, they need to effectively ...
Medical Xpress / Experimental plague vaccine strategy protects mice with missing key immune defenses
The plague has killed more people than World War II. The bacterium Yersinia pestis (Yp), which causes plague, has triggered three major pandemics throughout history, leaving behind a casualty toll of more than 200 million ...
Phys.org / Unraveling the climate behind the collapse of Bronze Age civilizations
The most severe droughts in the ancient Eastern Mediterranean arose when multiple natural climate cycles coincided, according to a new study from Stockholm University published in Science Advances. The findings shed new light ...
Phys.org / How did inbred brown tree snakes take over the island of Guam?
If you look up invasive species in a textbook, there's a good chance you'll find a picture of a brown tree snake. Native to Australia and the South Pacific, the brown tree snake arrived on Guam sometime after World War II, ...
