Phys.org / Twelve-year tracking suggests killer whales do not always drive shark disappearances
While killer whales (Orcinus orca) can trigger the immediate departure of white sharks (Carcharodon carcharias), extended absences from their aggregation sites are also part of the sharks' natural behavior, new research reveals.
Phys.org / Impact-formed glass provides evidence of cosmic collision in Brazil about 6 million years ago
For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth's surface. These structures, named geraisites ...
Tech Xplore / Personalization features can make LLMs more agreeable, potentially creating a virtual echo chamber
Many of the latest large language models (LLMs) are designed to remember details from past conversations or store user profiles, enabling these models to personalize responses. But researchers from MIT and Penn State University ...
Phys.org / Double white dwarf system detected in a nearby stellar cluster
Using the Very Large Telescope (VLT), astronomers have discovered a compact binary system consisting of two white dwarfs in the center of a nearby globular cluster designated NGC 6397. The finding was presented in a paper ...
Phys.org / How choices made by crowds in a train station are guided by strangers
In crowds, most people are strangers to you, and everyone else for that matter. However, until now, the effect of stranger-to-stranger interactions on the choices people make in crowds has not been properly examined. Ziqi ...
Tech Xplore / Robotaxis are coming to London. The city's famed black cab drivers are skeptical
The Ford Mustang Mach-E cruises down a London road choked with traffic, using its onboard AI system to avoid jaywalkers and cyclists, and navigate roadwork as it drives to its destination.
Phys.org / Archived tree cores reveal why boreal forests are getting starved for nitrogen
Despite decades of industrial deposition, nitrogen availability in the boreal forest is steadily declining. In a new study published in Nature, researchers from the Swedish University of Agricultural Sciences using decades ...
Medical Xpress / Study finds link between mental health diagnoses and early death in adults with cancer
In a study of adults with cancer, those who developed a mental health condition within the first year after their cancer diagnosis had a higher likelihood of dying over the next few years. The findings are published in Cancer.
Medical Xpress / Your gut microbes can be anti-aging—scientists are uncovering how to keep your microbiome youthful
People have long given up on the search for the Fountain of Youth, a mythical spring that could reverse aging. But for some scientists, the hunt has not ended—it's just moved to a different place. These modern-day Ponce ...
Phys.org / A key out-of-Africa site just got older: Dating methods push 'Ubeidiya site back at least 1.9 million years
A new study provides a clearer timeline for one of the most significant prehistoric sites worldwide for the study of human evolution. By integrating three advanced dating techniques, researchers have determined that the site ...
