Phys.org / Aboriginal artists painted giant ancestral beings as colonization arrived, study finds
Slithering across the ceiling of an Australian rock shelter is a giant snake with a crocodile-like head, razor-sharp teeth and a long tongue. It's more than 6 meters (20 feet) long, making it one of the largest Rainbow Serpent ...
Phys.org / Will new telescope Roman help reveal long-kept secrets of the universe? Q&A with an expert
On Sunday, Aug. 30, the Nancy Grace Roman Space Telescope is expected to launch from NASA's Kennedy Space Center in Florida. The observatory will join the Hubble Space Telescope, launched in 1990, and the James Webb Space ...
Medical Xpress / Gut bacteria linked to key brain chemicals in first-of-its-kind human study
The neuroactive potential of bacteria living in the human gut is associated with levels of key chemicals in the brain, according to a new study published in Molecular Psychiatry. The research team from the University of Surrey ...
Phys.org / Switching gravity on and off leaves particles behind, mathematical model finds
Hawking radiation causes black holes to eventually evaporate. This is because particle pairs are spontaneously created near the event horizon (the position of the last ray of light that can escape the black hole's gravitational ...
Phys.org / Resin-mounted wallaby teeth reveal rare 1,200-year-old ornaments in Queensland
While sorting through animal bones in a rock shelter in Queensland, Australia, archaeologists came across a tooth where something was "not quite right." Stuck to the tip of its root was a blackish-brown ball of glue-like ...
Phys.org / Major polluters are worsening the Western US water crisis: A new way to measure who's responsible
Climate change was once something scientists warned us about, and now it's a reality we are living in. In California's Central Valley, about one-third of climate-related groundwater loss between 2003 and 2024 can be attributed ...
Phys.org / Deep underground, SuperCDMS begins hunting light dark matter with 24 cryogenic crystals
In the hunt for one of nature's most elusive substances—dark matter, which makes up 85% of all matter in the universe—scientists are going to extremes. Deep underground and chilled to near absolute zero, the Super Cryogenic ...
Phys.org / An anomalous return of the Odden ice tongue suggests unusual Arctic conditions
Data from many sources, including NASA, have shown a significant decrease in Arctic sea ice since 1979. However, the processes driving the melting and freezing of sea ice are complex, and fluctuations occur throughout the ...
Phys.org / LEDs let archaeologists see the past in a new light
An archaeological excavation is a little like eating a layered cake: Once you have removed a layer, you cannot put it back. The problem becomes even trickier if two layers look almost exactly the same. Researchers from Aarhus ...
Phys.org / Physicists finally put Feynman's path integral to the test
For nearly 80 years, physicists have relied on a thought experiment created by Richard Feynman to predict how quantum particles behave. For the first time, researchers in China have tested this trick directly in the lab.
Phys.org / Saturn encounter may have set distant centaur on path to becoming a comet
More than 3 billion miles (4.8 billion kilometers) from Earth, an ancient icy object is slowly awakening. As it drifts inward through the solar system, the frozen body known as Centaur 450P/LONEOS has begun releasing gas ...
Phys.org / MeerKAT directly detects faint hydrogen signal from the distant universe
Astronomers from the University of Manchester and the University of the Western Cape have directly detected an extremely faint radio signal from hydrogen gas billions of light-years away, opening a powerful new way to map ...
