Tech Xplore / Should people marry AI agents?
The widespread use of conversational platforms such as ChatGPT and Gemini is raising important new ethical, anthropological and legal questions regarding the potential risks, misuses and shortcomings of artificial intelligence ...
Medical Xpress / Brain activity reveals how people juggle changing goals in real time
Nature never sits still, and neither does anything living within it, since paths keep shifting as things move through the world. Decisions work the same way, changing shape as we go rather than settling once and for all. ...
Phys.org / Early hardship may shape how oxytocin influences altruism
While humans are inherently social beings, they can interact and connect with others in very different ways. For instance, while some people tend to be more altruistic, others are less prone to helping their friends, acquaintances ...
Phys.org / Mars could have carried liquid water more recently than we thought
For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really the case, any liquid water would have long since either been locked ...
Phys.org / Twisted magnetic field around newborn star confirms decades-old jet theory
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) is a partner, have captured the first direct, high-resolution ...
Medical Xpress / Professor becomes his own test subject in longevity study; biological age found to be 15 years younger
Most individuals encounter their health primarily through an annual health screening, which provides a limited snapshot of their health status. A new study by the Yong Loo Lin School of Medicine, National University of Singapore ...
Phys.org / Quantum Latin squares cannot solve Euler's 36 officers problem without entanglement
Latin squares are arrangements of symbols in a grid in which every symbol appears exactly once in each row and column. These symbol arrangements, which were first studied more than three centuries ago, are now widely used ...
Phys.org / Mysterious Cygnus Bubble may trace back to microquasar, astronomers suggest
Astronomers have proposed a new explanation for the mysterious Cygnus Bubble, a vast cloud of ultra-high-energy gamma rays stretching thousands of light-years across the sky. While the bubble has generally been linked to ...
Medical Xpress / Adults 75 and older who stopped statins had similar three-year survival, trial finds
Stopping statins in adults 75 and older with no history of heart disease or stroke does not increase the risk of death over three years compared with continuing statins, although "bad" cholesterol rose around 50% in those ...
Medical Xpress / New obesity definitions reveal ill health more accurately than body mass index
Traditionally, obesity has been classified primarily using BMI, a measure of weight relative to height that provides limited information about whether excess fat is actually affecting a person's health. BMI levels have historically ...
Tech Xplore / AI agents struggle to perform original scientific research
Among the many predictions about the future of artificial intelligence is that models will one day be able to conduct scientific research on their own, leaving humans out of the equation. Already, they can write code, run ...
Phys.org / After commercial whaling nearly erased them, blue and fin whales are slowly reclaiming the southeast Atlantic
More than 40 years after the end of commercial whaling, new research reveals a recent increase in sightings of the world's two largest whale species in the southeastern Atlantic. The findings, published in the African Journal ...
