Tech Xplore / Workplaces look for cheaper AI as 'tokenmaxxing' fades as a corporate fad
A corporate fad of "tokenmaxxing" on artificial intelligence technology is hitting its limits as workplaces throwing AI at everything are seeing the costs rise without a similar spike in productivity.
Medical Xpress / HIV progress in 'real danger' as global funding plummets
The science has never been better, but political will has reached a new low: AIDS experts warned Monday that the fight against HIV was in real danger as funding fell by a fifth last year.
Phys.org / Fossil footprints reveal body size and group dynamics of 1.4-million-year-old human relative
Ancient footprints preserved along the shores of Kenya's Lake Turkana are reshaping scientists' understanding of one of humanity's extinct relatives. A paper published in Proceedings of the National Academy of Sciences describes ...
Medical Xpress / Longevity medicine has gone peptide-crazy
If there's a word that captures both the great promise and the persistent uncertainty of longevity medicine, it's peptides.
Phys.org / Extragalactic positron-annihilation hotspots might mean Milky Way produces far more positrons than thought
Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...
Phys.org / Review finds lack of evidence as to whether planting around our homes reduces the pollution we breathe
A new review led by the University of East London (UEL) has uncovered a major blind spot in air pollution research. Despite domestic gardens covering vast areas of Britain's towns and cities, researchers found no direct evidence ...
Phys.org / Astronomers are still trying to understand how a galaxy's spiral arms form
The Whirlpool galaxy (M51) is a classic grand spiral galaxy. It was the first object identified as a spiral, way back in 1845. At the time, it and other galaxies were considered spiral nebulae, since astronomers didn't know ...
Phys.org / Physicists capture first direct evidence of a Floquet topological state
A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological ...
Phys.org / Could we send a spacecraft to a black hole?
Black holes represent some of the most extreme environments in the universe. They are the sources of the strongest gravitational fields, allowing us to test Einstein's theory of general relativity to an extent impossible ...
Medical Xpress / Scientists decipher how T cells sense enemies—such as cancer—at point of contact
Every encounter between a T cell and a potential target—especially when that target is a developing tumor—begins with a rapid series of molecular decisions. Within seconds, the immune cell must determine whether to launch ...
Phys.org / Prolonged stretching reorganizes tissue scaffolds and uncages cell nuclei
How do tissues cope with being stretched for hours or even days? A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC) has uncovered an unexpected answer: Cells radically reorganize their internal ...
Phys.org / AI finds tiny gene editor changes that reduce unintended DNA edits
Gene editing is a highly precise and powerful technology that allows scientists to insert, delete, modify or replace DNA bases in living organisms. It has a variety of uses, including correcting disease-causing mutations ...
