Phys.org / Raccoons solve puzzles for the fun of it, new study finds
They raid compost bins, outsmart latches and sometimes look gleeful doing it. A new study in Animal Behaviour suggests raccoons may not just be opportunistic—they may be genuinely curious.
Phys.org / How changes on the Y chromosome may make species reproductively incompatible
When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males first, with hybrid males frequently failing to produce functional sperm even when hybrid females ...
Phys.org / Lost page of the Archimedes Palimpsest identified in Blois, central France
A page long believed to have been lost from the Archimedes Palimpsest, one of the most important surviving manuscripts of antiquity, has been identified at the Musée des Beaux-Arts in Blois, central France, by a CNRS researcher. ...
Phys.org / Gene edit makes probiotic safer for immunocompromised patients
An international team of researchers has modified a probiotic yeast to make it safer for use by immunocompromised people, older adults and infants. Testing in an animal model found that the modified yeast is less likely to ...
Phys.org / 'Peculiar' crocodile ancestor started life on four legs before learning to walk on two
A "peculiar" ancient relative of the crocodile which experts believe began life on four legs before, in adulthood, it learned how to walk on just two has been revealed in a new study. Named Sonselasuchus cedrus, this archaic ...
Phys.org / A brighter future may not suit everyone: Polar cod face difficulties due to warming
Under the Arctic sea ice, fish and plankton live in complete darkness, even in midsummer. Ice floes stop the sun's rays, especially if they are covered by snow. As the ocean heats up, the sea ice thaws, and new regions are ...
Phys.org / An interstellar comet packed with alcohol? What ALMA found in 3I/ATLAS
Comet 3I/ATLAS continues to make astonishing headlines, thanks to new findings from astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA). This new research reveals that 3I/ATLAS is packed with an unusually ...
Phys.org / Ancient hydrothermal carbon fuels microbes and crabs off Taiwan, study reveals
How is carbon metabolized and processed in different ecosystems? In a study published in the journal Communications Earth & Environment, researchers led by Joely Maak, the study's first author and researcher in the Cluster ...
Phys.org / Narrow-ridged finless porpoises are more social than assumed, study finds
A well-established fact of infancy in mammals is that the mother is the primary adult with whom an infant will interact. This holds true across species, from the tiniest shrew to the most massive blue whale. However, infants ...
Phys.org / Physical activity is linked to the health of the planet, according to a trio of recent studies
Global levels of physical activity have not improved over the past two decades, despite widespread policy development and adoption, and large disparities persist across gender and socioeconomic groups. The findings from three ...
Phys.org / ESA analyzing fireball over Europe on 8 March 2026
At approximately 18:55 CET (17:55 UTC) on Sunday, March 8, 2026, a very bright fireball moving from the southwest to the northeast was observed by many people in Belgium, France, Germany, Luxembourg, and the Netherlands.
Phys.org / Strontium optical clock accurate to within 1 second over 30 billion years
Researchers from the University of Science and Technology of China have achieved a major breakthrough in optical clock technology, developing a strontium optical lattice clock with stability and uncertainty both surpassing ...
