A new statistical analysis of archival sky surveys from the early Cold War has found that mysterious, short-lived bursts of light in the night sky were more likely to appear around the time of above-ground nuclear weapons tests and to increase alongside reports of unexplained aerial phenomena (UAPs). Four exposures of the 3 x 3 arcmin region of sky centered on the triple transient identified in July...

The Jovian system has four large moons, including the largest moon in the Solar System, Ganymede, whereas the Saturnian system is dominated by one giant moon. New simulations suggest Jupiter’s powerful magnetism carved a gap in its early disk, helping capture and preserve major moons like Io and Ganymede, while Saturn’s weaker field left its system sparsely populated. Jupiter (lower left) has...

New evidence from Germany suggests Neanderthals captured European pond turtles (Emys orbicularis) around 125,000 years ago, likely valuing their shells as tools rather than their modest meat yield.

Using high-resolution CT and synchrotron scanning, paleontologists confirmed that the fossilized specimen from the Early Triassic of the South African Karoo Basin contains an unborn dicynodont Lystrosaurus, resolving a long-standing mystery about whether early mammal ancestors laid eggs. The researchers suggest the dicynodont eggs were likely soft-shelled, explaining why they have remained elusive...

Honeybees (Apis mellifera) are important ecological and agricultural pollinators. In the United States, beekeepers experience substantial annual colony losses, largely driven by parasites such as the mite Varroa destructor. In new research, scientists studied a hybrid honeybee population in Southern California, a genetic mix of Western European, Eastern European, Middle Eastern, and African lineages....

Using data from over one billion proton-colliding events collected at CERN’s Large Hadron Collider (LHC), physicists have measured the mass of the W boson with record accuracy. The value matches the Standard Model’s prediction, giving the researchers confidence that no unexpected force is hiding in the measurement. CMS candidate collision event for a W boson decaying into a muon (red line) and...

In new research, University of Galway’s Dr. Martin David Mulligan and his colleagues followed nearly 800 participants from the Framingham Heart Study for more than a decade and a half, examining whether vitamin D levels measured in their 30s were linked to changes in the brain in later life. They found that individuals with higher circulating levels of vitamin D had lower accumulations of tau —...

Scientists have extracted and analyzed DNA from 216 canid remains, including 181 from Paleolithic and Mesolithic Europe. The oldest data that they recovered are from a 14,200-year-old dog from the Kesslerloch site in Switzerland. Their results suggest that domesticated dogs (Canis lupus familiaris) predate farming and share deep ancestry with wolves (Canis lupus) from Eurasia, challenging ideas about...

By tracing magnetic signals preserved in 3.5-billion-year-old rocks in Western Australia, geoscientists have found the oldest direct evidence yet that parts of the planet’s outer shell were shifting across the globe, pushing the origins of plate motion deep into Earth’s early history.
