Chronic stress, the prolonged exposure to psychological and/or physical strain, is known to be a risk factor for depression, anxiety and some other psychiatric disorders. Past studies suggest that chronic stress disrupts the integrity of myelin, a fatty insulating layer that surrounds nerve fibers and helps electrical signals travel efficiently between brain cells.
India will prepare contingency plans to help farmers weather potential low rainfall linked to the El Niño weather system, agriculture officials said Tuesday.
More than three-quarters of psychologists report their patients are discussing artificial intelligence in therapy, using the technology to seek additional support with their mental health, find a diagnosis, or for friendship and intimate relationships, according to a survey by the American Psychological Association.
The Life House Impact Project, led by Dr. Georgia Bowers, Professor Andrew King and Dr. Richard Green, worked with older LGBTQ+ people to document their real concerns about housing and social care—and then brought those experiences into training for the people responsible for that care. The report shows that the proportion of staff who said they regularly or always met their LGBTQ+ service users' needs rose from 55% to 85% in the weeks following the training.
Scientists have found that hidden health signals coating your cells could change medicine forever. The new study by Edith Cowan University (ECU) School of Medical and Health Sciences has shown sugar molecules in your body may reveal disease long before it's detected. The research, published in Nature Chemical Biology, shines a spotlight on glycans—tiny, complex sugar chains that coat your cells and proteins.
Scientists have discovered a new protective communication circuit between specialized immune cells in the intestines, a circuit that may be therapeutically targeted to improve inflammatory bowel disease outcomes, according to a recent study published in the Proceedings of the National Academy of Sciences.
When female bottlenose dolphins want to avoid males known for pushy mating behaviors, they listen out for their unique signature whistles. That's the suggestion of a study published in Proceedings of the National Academy of Sciences that tracked a population of Indo-Pacific bottlenose dolphins in Shark Bay, Western Australia.
Researchers using two of humanity’s most powerful observatories — NASA’s James Webb and Hubble Space Telescopes — have definitively shown that Terzan 5 is not a globular star cluster as it was once classified, offering new insight into how galaxies like our own form and evolve over time. A globular star cluster typically has only […] The post NASA Webb, Hubble Reveal History of Relic of Milky Way’s Formation appeared first on NASA Science.
Among the body's most crucial protective features are the brain barrier systems, including the blood-brain and blood-cerebrospinal fluid (CSF) barriers. These barriers are made of highly specialized cells that allow essential nutrients to enter yet repel dangerous toxins and pathogens that may be circulating in the bloodstream. Scientists have long known what these barriers do, but less about how they are built during development.
What do hurricanes, military equipment, aromatherapy oil and a pet raccoon have in common? According to a new review led by Menzies School of Health Research (Menzies), all have been linked with cases of melioidosis, a potentially fatal disease caused by the bacterium Burkholderia pseudomallei, as part of tracking the global spread of the disease.
Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) have found that when a supermassive black hole tears apart an unlucky star, the fireworks are not over when the first flash fades. Years after the initial outburst, many of these black holes "burp" out streams of material that slam into surrounding gas and glow in radio waves, giving the NSF VLA a front-row seat to how black holes grow and blast energy back into their galaxies.
Scientists await a big splash in the Pacific Ocean as one of the most research-packed Dragon spacecraft to date returns, completing the 34th SpaceX commercial resupply mission to the International Space Station for NASA. Biological and materials samples, along with tested hardware, are heading back to research teams on Earth for further analysis, advancing NASA's work to prepare humans for exploration beyond low Earth orbit and to deliver benefits back home.
Astronauts aboard the International Space Station have switched on NASA’s newly upgraded Cold Atom Lab, a one-of-a-kind facility designed to improve how scientists explore the fundamental workings of matter and develop new quantum technologies. By leveraging the unique environment of microgravity in space, the lab can accomplish cutting-edge science impossible to do anywhere else. Quantum […]
In this edition of STAT Health Tech: How a biotech startup turned a failed clinical trial into an AI model, and more.
At 12:25 p.m. EDT, the unpiloted SpaceX Dragon spacecraft undocked from the forward‑facing port of the International Space Station’s Harmony module after a command from SpaceX ground controllers. Flight controllers delayed the undocking slightly to power‑cycle a navigation sensor and restore full redundancy before departure. The post Dragon Undocks to Return Science Experiments to Earth appeared first on NASA Science.
A chain of remote islands and underwater volcanoes between Alaska and Kamchatka has revealed a much older chapter in Earth's tectonic history than previously known. Along the Aleutian Arc, the Pacific Plate dives beneath the North American Plate, creating one of the most active and important plate boundaries on Earth. An international research team has now shown that this subduction zone began at least 56 million years ago, significantly earlier than previous models had assumed. The findings, published in Nature Communications, shed new light on a major reorganization of plate motions and may also help better understand ancient global climate change.
Half of young men in Switzerland are concerned that "real men" are increasingly being marginalized in society. A large-scale study by the Jacobs Center for Productive Youth Development at the University of Zurich (UZH), in collaboration with männer.ch, shows how prevalent restrictive and dominance-based concepts of masculinity are. These ideas go hand in hand with misogyny, a propensity for violence and opposition to gender equality. Prevention efforts should start in schools.
New research from large population studies provides invaluable evidence on genome screening of newborn babies to reduce risks from overdiagnosis. The authors conclude that further studies are needed before such screening is rolled out.
Most of the earthquakes we hear about are due to tectonic plates colliding or sliding past each other near plate boundaries. Yet researchers have detected some enigmatic earthquakes happening inside the more stable interiors of plates. Intermediate-depth earthquakes (IDEs), which occur around 70–300 kilometers (43–186 miles) below the surface, are especially puzzling because rocks at those depths are hot enough to flow more fluidly.
In a new study published in Science Immunology, researchers at King's College London looked at a type of tissue important for the immune response called gut-associated lymphoid tissue (GALT), which is located within the lining of the gut. Unlike other tissue structures in the gut lining that act as a barrier between the trillions of bacteria in the gut and the rest of the body, GALT actively transports gut microbes into the body. By doing this, GALT activates immune responses that help maintain a stable relationship with beneficial gut bacteria.
