An international online survey of young people found that those who spend more time on social media and on dating apps tend to have slightly lower body satisfaction and appreciation. People who spent more time on social media also had a slightly higher desire to be slim, and the more time they spent on dating apps, the more they had a slightly higher desire to be muscular. The paper was published in. British Journal of Health Psychology. Social media and dating apps have become central to many young people’s daily lives, shaping not only how people communicate but also how…
More than 50 years ago, physicist Sir Roger Penrose proposed the surprising idea that under the right conditions, it might be possible to extract energy from rapidly rotating black holes. His concept is that a particle that enters a black hole’s ergosphere (the region in which space-time is dragged by the object’s rotation) could split into two. One fragment falls into the black hole, and the other fragment escapes, carrying away more energy than the original particle. Later, physicist Yakov Zeldovich expanded on this concept and predicted that waves interacting with objects rotating at sufficient speed could also gain energy…
Artificial intelligence models are meant to make choices for us, but they tend to be highly susceptible to subtle changes in the way choices are presented. Recent research published in Proceedings of the National Academy of Sciences This provides evidence that AI agents overreact to small cues in the environment and react much more strongly to these nudges than humans. This hypersensitivity suggests that relying on current language models to make autonomous decisions can lead to unpredictable and easily manipulated outcomes. People increasingly expect language models to do more than just chat. Large language model-based software programs, commonly known as…
A plan to bury carbon under remote farmland in Indiana would be a major blow to climate change, proponents say, but it’s all generously funded by U.S. taxpayers.But as far as Melissa Harrison and other residents of Climbers, Indiana are concerned, that may be the end for their town. “This is our place,” she says. Generations of her family are buried in this cemetery, and she raises her five grandchildren in one of dozens of white clapboard homes surrounded by cornfields and agricultural mills.Now, a local ethanol plant is leading a project to bury vast amounts of carbon deep in…
When a public health crisis occurs, government officials believe that educating the public accurately about the threat will naturally encourage safe practices. The general expectation is that people first need to be persuaded that a medical intervention is effective before they actually use it. A large-scale study assessing the political response to the coronavirus pandemic challenges this assumption. Researchers who tracked reactions to former President Donald Trump’s unexpected support for mask-wearing in 2020 found that his supporters readily adopted the behavior without changing their personal beliefs. These findings were published in American Sociological Review. Social scientists have been debating for…
Researchers at the University of Alabama at Huntsville (UAH), part of the University of Alabama System, have identified a promising new use for continuous low-intensity ultrasound that may one day help treat joint injuries and reduce the risk of post-traumatic osteoarthritis. Their findings suggest that the non-invasive approach may shift the body’s immune response from long-term inflammation to tissue repair, providing a potential drug-free strategy to improve healing. The study was published in the journal Nature scientific reportled by Dr. Anuradha Subramanian, professor of chemical and materials engineering. It combines biological research conducted by Dr. Shahid Khan during his doctoral…
Recent research is Journal of social and personal relationships This provides evidence that our early relationship blueprints shape our risk of developing dependence on romantic partners through two specific psychological processes. The findings suggest that the ability to remain psychologically flexible and regulate emotions acts as a bridge between a person’s attachment style and the likelihood of experiencing compulsive and unhealthy relationship dynamics. People bring deeply ingrained emotional blueprints to their adult romantic relationships. These blueprints, known in psychology as attachment styles, develop during early childhood interactions with primary caregivers. The resulting attachment style serves as an internal working model…
Sailing’s governing body is considering how Olympic-class equipment is made, used and disposed of in order to make changes that will ultimately reduce its impact on the environment.World Sailing’s Director of Sustainability, Alexandra Rickham, said this unique life cycle assessment project will give organizations the evidence they need to make smarter choices and shape the future of Olympic equipment. “Sailing naturally has a close relationship with nature and the environment. Sailing is very much seen as a clean, green sport that takes advantage of the wind,” she said. “But the reality is that our equipment is having an impact. It’s…
Researchers at Georgetown University have found new evidence that as people acquire skills, their brains physically reorganize, allowing well-practiced tasks to become automatic. The findings challenge the long-held idea that humans are incapable of truly multitasking and suggest that with enough experience, the brain can perform certain activities at the same time, rather than simply switching between them quickly. This discovery could have implications beyond everyday life. This could help scientists better understand how habits form, why some behaviors are difficult to change, and how future artificial intelligence systems can build new skills from previous learning. “This is a new…
Gold has been prized since ancient times for its long-lasting shine. Now, researchers at Tulane University have discovered an important reason why precious metals resist tarnishing. Their findings show that gold’s durability is not determined solely by its chemical properties. Instead, the arrangement of atoms on the surface plays a key role. This study physical review letterfound that certain gold surface atoms spontaneously migrate into a protective pattern that makes it very difficult for oxygen to react with the metal. This newly identified behavior helps explain why gold jewelry, coins, and other objects can maintain their shine for centuries. It…
