Phys.org / Drier soils may turn late summer into prolonged extreme heat
The summers of recent years have been hot, but not unusual from a meteorological perspective. According to researchers at Leipzig University, though, the next extreme summer would far exceed anything we have experienced so ...
Phys.org / Tomato roots reveal hidden steps in 400-million-year-old fungal partnership
Scientists at VIB and Ghent University have produced the first high-resolution, cell-by-cell map of how tomato roots respond to colonization by arbuscular mycorrhizal fungi. These ancient fungal partners help plants absorb ...
Phys.org / Cells remodel actin normally without coronins, challenging textbook view
Coronins are found throughout the animal kingdom, from single-celled amoebae to humans, and are involved in many vital processes, including immunity, development and cell survival. For decades, textbooks and hundreds of scientific ...
Phys.org / Long-range magnetic interactions govern how a ferrimagnet approaches its phase transition
Close to a phase transition, very different materials can follow the same mathematical rules. The concept of universality, which groups seemingly distinct systems based on their common properties, was developed to describe ...
Phys.org / Distinct neurons drive mice's social sounds and squeaks
Mice use almost completely distinct sets of neurons for their two different types of vocalizations—the squeaks they produce when in distress or fighting and the whistle-like ultrasonic vocalizations they use when communicating ...
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 ...
