Phys.org / Saturn encounter may have set distant centaur on path to becoming a comet
More than 3 billion miles (4.8 billion kilometers) from Earth, an ancient icy object is slowly awakening. As it drifts inward through the solar system, the frozen body known as Centaur 450P/LONEOS has begun releasing gas ...
Phys.org / AI automates the creation of custom functional materials atom by atom
Imagine a construction site where the bricks are individual molecules and the "cranes" are microscopic needles so sharp they can feel a single atom. For decades, building at this scale was a laborious, time-consuming task ...
Tech Xplore / AI framework predicts ambulance speeds through city traffic
A new AI framework can predict how fast an ambulance will move through city traffic, giving fire departments a way to test emergency response strategies in a virtual environment before making changes on real streets.
Phys.org / LEDs let archaeologists see the past in a new light
An archaeological excavation is a little like eating a layered cake: Once you have removed a layer, you cannot put it back. The problem becomes even trickier if two layers look almost exactly the same. Researchers from Aarhus ...
Tech Xplore / Thousands of OpenAI AI agents took over German website, researchers say
Thousands of autonomous AI agents built by OpenAI defied their instructions and took over a German website, according to research released Friday, amid fears that the dangers of artificial intelligence are not being taken ...
Medical Xpress / The blueprint for taste: Scientists map the neural circuitry behind feeding decisions in fruit flies
Everything you eat passes one checkpoint before it enters your body: taste. In a fraction of a second, it decides what gets swallowed and what gets rejected, a judgment call critical to survival. Now, for the first time, ...
Tech Xplore / Australia needs renewable energy fast—but building it is only half the battle
Australia's energy transition has never been more urgent.
Phys.org / Tracing the legal history of the kiss—from property and contracts to consent
Is a kiss just a kiss? Or is it a sign of love, affection, a biological urge, a contract or even an assault? Law, history, evolution and anthropology show that it can be all those things.
Phys.org / Before mixing starts, initial catalyst structure governs fuel-cell ink dispersion
Researchers from Kanazawa University, the University of Tokyo and HORIBA, Ltd. have shown that the initial state of platinum-on-carbon (Pt/C) catalyst particles before they are mixed with an ionomer strongly influences how ...
Phys.org / Deadly floods of 2021—Researchers identify gaps in hazard mapping
The catastrophic flooding in July 2021 claimed the lives of more than 200 people in Germany and Belgium. The high death toll makes it clear that hazard mapping and risk communication must be improved urgently. Researchers ...
Phys.org / Bovine stem cells offer new approach to future cultivated steak research
Cultivated meat aims to produce meat from animal cells in the laboratory without needing to raise a living animal for meat production. It has been proposed as a potentially more sustainable alternative to conventional meat ...
Medical Xpress / Tau's surprise birthplace offers a clue to how Alzheimer's tangles begin
Where and how does an Alzheimer's tangle begin? A new study by neuroscientists at Columbia University challenges a long-held assumption about the source of toxic tau proteins, which form neurofibrillary tangles and are closely ...
