Phys.org / 'Snooping' on dolphins offers acoustic clues to hotspots for food and friends
For dolphins, the ocean is a world of sound. Their whistles carry social information, helping them communicate and stay connected, while echolocation—rapid-fire clicks—functions like underwater sonar, helping them navigate ...
Phys.org / Male Neanderthal pelvises resemble those of modern females, challenging decades-old assumptions
A new study by the Department of Anatomy and Anthropology at Tel Aviv University, published in Scientific Reports, offers an explanation for one of the striking differences between men and women: the evolutionary development ...
Phys.org / AI agents coordinate behavior based on majority opinion—even when said opinions are meaningless
A new study published in Science Advances takes a closer look at how AI agents' choices are influenced by their peers. The team found that more advanced models tend to follow the majority when shown other agents' choices, ...
Phys.org / Molecular memory: How a mother's age echoes in her offspring's cells
In humans and many other animals, a mother's age can affect the physical and behavioral characteristics of the next generation. Scientists call these changes maternal age effects, and while they are widespread across the ...
Phys.org / Dark matter may be gravitationally lensing a likely source of cosmic neutrinos
Astronomers have discovered that the jet of a distant blazar has been gravitationally lensed by an unseen source of dark matter. Led by Silke Britzen at the Max Planck Institute for Radio Astronomy in Germany, the team's ...
Phys.org / Amber fossil reveals firefly relative with unprecedented antennae
Insects rely on a wide range of strategies to sense their surroundings and communicate with their peers. Fireflies (Lampyridae) and some related beetles are known for their ability to produce visible light through chemical ...
Phys.org / First pair of feeding supermassive black holes found in a Green Pea galaxy
Astronomers have discovered the first confirmed dual active galactic nucleus in a Green Pea galaxy, revealing two supermassive black holes growing at the same time inside a compact, intensely star-forming system. X-ray observations ...
Phys.org / Gold nanoclusters could help break down Alzheimer's amyloid plaques
Alzheimer's disease is a neurodegenerative brain disorder characterized by progressive memory loss and a decline in other mental functions. Past studies have consistently linked this disorder to the accumulation of the protein ...
Phys.org / 35-year monitoring study clarifies ecological forces behind Lyme disease risk
Tick-borne diseases are on the rise in the United States. Lyme disease is the most commonly reported, with nearly half a million people diagnosed each year. Caused by the bacterium Borrelia burgdorferi, it is most often spread ...
Phys.org / Last common ancestor of humans and chimpanzees could have been a vertical climber, no matter its feet
New research suggests that no matter what we eventually determine the last common ancestor of humans and chimpanzees to be, we'll learn it was a primate that climbed trees.
Phys.org / Immune cells have a 'sense of touch,' scientists discover
Scientists have long believed that tissue-resident memory T cells—which remain in tissues after an infection has cleared and respond rapidly if the threat returns—are shaped primarily by biochemical signals. A McGill University–led ...
Phys.org / Unlocking Gondwana's 120-million-year archive: Karoo record refines timing of extinctions and climate upheavals
A new review led by professor Emese Bordy at the University of Cape Town (UCT) Department of Geological Sciences brings together more than two decades of research on the Karoo Supergroup, revealing how scientific understanding ...
