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 ...
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 / 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 ...
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 ...
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 / 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 ...
Tech Xplore / Helmholtz resonance powers miniature boats and ultrasonic flying robots
When air is blown across the neck of a bottle, it doesn't just produce a pleasant tone: it also demonstrates a phenomenon called Helmholtz resonance. This occurs when airflow passing across an opening causes air trapped inside ...
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 / Nonrepeating photonic crystal may enable more tunable, reliable semiconductor lasers
Over the past two decades, photonic-crystal surface-emitting lasers (PCSELs) have shown promise as a type of advanced semiconductor laser useful in defense- and aerospace-related applications. Typically, these devices are ...
Medical Xpress / Curiosity has its own neural signal: Brain separates valuable information from water rewards in mice
Often, humans and other animals seek information that can help them complete tasks and attain desired rewards. In some cases, however, they seek information driven simply by curiosity and a desire to obtain knowledge for ...
Medical Xpress / New gas-switching approach could one day make deep-sea decompression safer and faster
Deep-sea divers must be careful to prevent decompression sickness, also known as "the bends," when ascending from the high-pressure depths of the ocean. Failing to do so can result in anything from muscle cramps and skin ...
