Phys.org / Why Europe's rising plant diversity may signal habitat disruption, not ecological recovery
The number of plant species in many ecosystems in Europe has grown rather than shrunk over the last 100 years. However, this is not necessarily cause for celebration, as this local increase is primarily due to generalists ...
Phys.org / Disorder creates direction-dependent optics in compound semiconductors
An international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, ...
Phys.org / Ultra-faint galaxy discovered near Andromeda may be 12.5 billion years old
A new ultra-faint dwarf galaxy has been discovered in the vicinity of Andromeda (M31), the Milky Way's large neighboring galaxy. The new study, published in Astronomy & Astrophysics suggests that the galaxy, named And XXXVI, ...
Phys.org / Off-center stellar death points to wandering supermassive black hole stripped of its own galaxy
Astronomers have uncovered new details about the black hole that ripped apart a star in a tidal disruption event named AT2024tvd. Findings suggest it is a wandering supermassive black hole—the kind that is not located at ...
Medical Xpress / AI companionship may reshape how teens learn conflict, boundaries and empathy
As teenagers increasingly turn to artificial intelligence chatbots for advice about friendships, family conflicts and romantic ties, researchers are raising concerns that the technology could disrupt how young people learn ...
Phys.org / Cochlea network model reveals how inner ear may sort sound from noise
Over 70 million people in the U.S. are impacted by hearing loss, and age-related hearing loss is the second most common health problem in older adults, according to the Advanced Research Projects Agency for Health. However, ...
Phys.org / Great Barrier Reef drilling reveals repeated collapse, regrowth and migration since last ice age
An international expedition including University of Sydney researchers has pieced together the clearest picture yet of how the Great Barrier Reef responded to dramatic environmental change over the past 30,000 years. Multiple ...
Phys.org / Cultural values may decide when comforting others feels like real support
When someone you love is upset, your first instinct may be to comfort them. To reassure them. To make them feel better. But what if that instinct isn't universal?
Phys.org / A goat's tooth may have solved a 100‑year debate about ancient Greek farming
The agricultural economy was the backbone of wealth in ancient Greece. Food brought people together, whether in smaller groups at a wine-drinking symposium or the entire community in a sacrificial feast of epic proportions. ...
Phys.org / Analyzing avalanches on asteroid Vesta offers new method for understanding regolith processes
A study conducted at the Institut de Physique du Globe de Paris uses images from NASA's Dawn mission and a Bayesian inversion of the Hapke photometric model to analyze avalanches and ejecta deposits on the asteroid Vesta. ...
Phys.org / Table sugar could hold a cheaper, quicker key to making vital drugs
Pioneering research has developed a new way of creating carbohydrate-based medicines that could ultimately replace costly drugs for common health conditions, using two cheap basic ingredients—table sugar and vinegar.
Phys.org / Urban growth may slow by 2100, leaving big cities smaller than expected
The world is urbanizing fast. In 1975, about 11% of the global population lived in cities with more than 1 million inhabitants. "Today, we estimate that share to be about 24%," says Andrea Musso, junior fellow at the Complexity ...
