Medical Xpress / Low-dose THC keeps breast cancer cells in tumor models from reverting to an aggressive state
Recent discoveries have revealed that breast cancer cells are more flexible than previously thought. Some can change from a differentiated state, when a mature cell has taken on a specific function, back to a more stem-like ...
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 / Eight-letter DNA alphabet is accurately transcribed by a natural enzyme
All known life on Earth uses the same genetic alphabet, consisting of four letters. Now, researchers at the University of California San Diego have demonstrated that one of biology's most essential enzymes can accurately ...
Phys.org / Geomagnetic superstorm shook GPS accuracy across the US—its timing may have averted agricultural losses
On Nov. 11, 2025, Earth experienced a severe geomagnetic storm triggered by solar flares and coronal mass ejections from an active sunspot region. While this kind of storm brings beautiful auroras admired in many areas around ...
Tech Xplore / A new kind of AI that does its thinking cheaply without words
There may soon be a new kind of artificial intelligence in town, one that uses a novel approach to thinking that could save massive amounts of computing power and money.
Phys.org / A supermassive black hole erupted in X-rays, and its radio jets followed 300 days later
By combining roughly two decades of observations from NASA's Swift X-ray Telescope with radio monitoring, astronomers have caught a supermassive black hole at the heart of the Perseus Cluster suddenly flaring in X-rays, and ...
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 / 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 / Bovine stem cells offer new approach to future cultivated steak research
Cultivated meat aims to produce meat from animal cells in the laboratory without needing to raise a living animal for meat production. It has been proposed as a potentially more sustainable alternative to conventional meat ...
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 / 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 / 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 ...
