Phys.org / Sun simulations reveal how cool prominences survive in million-degree corona
At more than one million degrees, the sun's atmosphere—the corona—is incredibly hot; but not everywhere. Time and again, huge structures of significantly cooler solar plasma—about 10,000 degrees—appear within the corona. ...
Phys.org / Cosmetics from waste? Microbial discovery unlocks greener route to high-value chemical products
Researchers at University of Toronto's Department of Chemical Engineering & Applied Chemistry have made a key discovery about how certain bacterial strains produce a set of economically valuable chemicals—opening the door ...

A joint study by the EHU-University of the Basque Country and the BC3 research center reveals that EVs are concentrated in households with high incomes, higher levels of education and located in urban areas, which highlights ...
Phys.org / Waste biomass helps unlock hydrogen and formate in lower-energy electrolysis
A research team has developed a high-efficiency electrochemical system that simultaneously produces hydrogen and value-added chemicals using glycerol, a low-cost, abundant byproduct of biodiesel production. The findings are ...
Phys.org / Can jarrah forests be recovered after bauxite mining?
In February, mining company Alcoa was hit with a $55 million penalty for illegally clearing about 2,000 hectares of WA's Northern Jarrah Forest. About $40 million was earmarked for so-called "permanent ecological offsets," ...
Medical Xpress / How different countries decide who gets a heart transplant
As demand for heart transplants continues to far exceed the number of available donor hearts, experts at the 46th Annual Meeting and Scientific Sessions of the International Society for Heart and Lung Transplantation (ISHLT) ...
Medical Xpress / More children are surviving long enough for heart transplants—but not enough hearts exist, say experts
Advances in pediatric heart care are helping more children survive long enough to receive a transplant—but a critical shortage of donor hearts means too many are still dying while they wait, experts warned at the International ...
Tech Xplore / Do AI language models 'understand' the real world? On a basic level they do, suggests study
Most of what AI chatbots know about the world comes from devouring massive amounts of text from the internet—with all its facts, falsehoods, knowledge and nonsense. Given that input, is it possible that AI language models ...
