Tech Xplore / OpenAI unveils AI chip Jalapeno
OpenAI on Wednesday unveiled its first custom-designed computer chip, called Jalapeno, built to run ChatGPT and other artificial intelligence products faster and more cheaply.
Medical Xpress / Multiple sclerosis impacts daily life far beyond its physical symptoms, new study finds
Multiple sclerosis (MS) can have a substantial impact on many aspects of life beyond physical health, with 51% of people reporting that the disease affects their social life and 48% reporting that it affects their work, according ...
Phys.org / Sponges may cut methylmercury contamination in marine food webs by more than 50%
Marine sponges may play an important, previously underestimated role in reducing methylmercury contamination in marine food webs. In a new modeling study, researchers at Helmholtz-Zentrum Hereon showed that sponges can significantly ...
Phys.org / A magnetic field that kills superconductivity can also bring it back
Magnetic fields are generally known to destroy superconductivity in a material. However, in exceptional cases, they can lead to what is known as "re-entrant superconductivity"—where superconductivity disappears as expected, ...
Tech Xplore / Top developers are pivoting from chatbots to physical AI
Computer scientist Louis Castricato was in his eighth year studying large language models—the artificial intelligence technology behind chatbots like ChatGPT and Claude—when he started to feel like he was hitting a dead end.
Phys.org / Corrected Pantheon+ analysis of supernovae challenges accelerating universe claim
Research led by the Tata Institute of Fundamental Research, Mumbai, along with Professor Subir Sarkar from the University of Oxford, questions the widely accepted argument that the expansion rate of the universe is accelerating ...
Medical Xpress / AI system detects sudden cardiac death risk, identifying thousands more patients annually
Each year in the U.S., more than 300,000 people die from sudden cardiac arrest, a condition in which the heart's electrical system malfunctions without warning. The medical emergency can kill both high-risk older adults and ...
Phys.org / Shorter front-leg strides can be an early warning sign of dementia in senior dogs
Scientists have shown that the stride length of the front legs (but not the hind legs) of senior and geriatric dogs decreases as their cognitive performance worsens. In contrast, chronological age itself was a poor predictor ...
Phys.org / Pathway to high-fidelity quantum computing identified
Researchers from the University of Sydney, working with IBM, have identified and quantified important factors limiting the performance of quantum computers and demonstrated ways to overcome their impact.
Phys.org / Check politics at the door? Not at many workplaces, researcher says
When people think of workplace segregation, they usually think of race or gender. Yet Americans are also sorted at work by something employers rarely measure: how they vote.
Tech Xplore / Should we fear an AI bubble bust?
Recent swings in tech stocks are reviving fears of an AI bubble—and some experts warn that if it pops, the fallout could be bigger than anything Wall Street has ever seen.
Phys.org / Scientists develop predictive roadmap to boost performance in next-gen spintronics
Chiral 2D metal halide perovskites (MHPs) are among the most promising materials for future technologies that exploit the spin of electrons in spin-based optoelectronics, or spintronics, but getting them to perform consistently ...
