Phys.org / Existing drug could treat invasive canine oral tumors
A benign but invasive canine oral cancer is often mistaken for a similar malignant one, leading to misdiagnoses in close to a third of cases. But a new diagnostic tool can now distinguish between the two, according to a new ...
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 / Why Korean 'aegyo' speech sounds cute: Adults raise vocal resonances to sound younger and smaller
In Korean, the term "aegyo" denotes a playful cuteness put on by adults to win someone's affection, typically in romantic contexts. This is usually accomplished with bashful expressions or a childlike manner of speaking sometimes ...
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 / 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 / Curved surfaces reshape active materials, localizing vibrations near defects
Many materials, both living and engineered, are powered from within. Scientists have thoroughly investigated how such 'active' materials operate, but so far, mostly in circumstances where the curvature of the environment ...
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 / A single asteroid impact may explain the appearance of Mars' moon Deimos
Deimos, the smaller and outermost of Mars' two moons, is roughly oval in shape and has a deep depression at its south pole. Unlike its heavily scarred sister moon, Phobos, Deimos is covered by a loose layer of dust and rubble—a ...
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 / Each degree of warming could add a month of intolerable heat for 1 billion people
The threat that rising temperatures fueled by climate change pose to the health of older people has been dramatically underestimated, according to a U.S. modeling study published Tuesday.
Phys.org / Ancient Egyptian tomb shows how burial trends changed over hundreds of years
The Theban Necropolis, opposite Luxor, consists of more than 400 tombs. In a new Frontiers in Environmental Archaeology study, researchers in Spain examined part of one of these tombs—chamber three in tomb TT 209—to reconstruct ...
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 ...
