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 / 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 ...
Phys.org / Firelight may have sparked human storytelling by extending social hours
New research from the University of St Andrews has developed a novel hypothesis of how firelight was critical to the evolution of sophisticated storytelling.
Phys.org / Single amino acid swap expands nanoparticle vaccine approach to influenza viruses
Influenza viruses constantly shapeshift to evade recognition by the immune system. This shapeshifting occurs in critical proteins like hemagglutinin (HA), which controls how the virus attaches to human cells before entering ...
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 / 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 / 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 / In tune with nature: Human speech follows a rhythm that is also found in the animal kingdom
The temporal structure of speech rhythms resembles that of the communication signals of numerous animal species. This is shown by a study conducted by a research team from the Leibniz Center for General Linguistics (ZAS) ...
Phys.org / Muddying the waters makes stickleback fish more coordinated, study finds
Stickleback fish can change their social behavior to help them find food in cloudy water, according to a new University of Bristol study published in Proceedings of the Royal Society B.
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 ...
Phys.org / Canada's Labrador Shelf preserves climate records once thought erased by ice
The Labrador Shelf is a shallow marine area on the margin of the Labrador Sea in the North Atlantic off the east coast of Canada. During the last ice age, this region was covered by the Laurentide Ice Sheet, one of the largest ...
Phys.org / Ocean heat waves linked with poorer health among children in coastal communities
Marine heat waves—periods of abnormally warm ocean temperatures—may have negative health effects on children who live in coastal communities in low- and middle-income countries, according to a study led by researchers at ...
