Deep learning helps discover hundreds of Antarctic earthquakes coming from an unlikely location

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.

Mapping immune cell interactions in gut tissue reveals changes in ulcerative colitis

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.

Why hotel crisis plans collapse when panic sets in, according to hospitality leaders

Hospitality leaders are being forced to handle far more than operational disruption when crises hit, according to new research from the University of Surrey. Researchers found that modern crises demand emotional resilience, ethical judgment and rapid decision-making under intense public scrutiny.

Chandra tracks M87 black hole's evolving jet in finest X-ray detail yet

An international team of astronomers led by Camille Poitras, a Ph.D. student in the Faculty of Science and Engineering at Laval University, has produced the most detailed X-ray view ever obtained of the jet launched by the supermassive black hole in the galaxy M87. By combining observations from NASA's Chandra X-ray Observatory acquired between 2012 and 2025 with advanced image-processing techniques, the researchers were able to track the evolution of jet structures with unprecedented detail.

How do recovery community centers support people in recovery over time?

More than 1 in 10 adults in the United States believe they had a substance use problem at some point, according to the Substance Abuse and Mental Health Services Administration. Among these adults, more than 7 in 10 considered themselves to be in recovery. An increasingly common way people support their recovery is by visiting recovery community centers (RCCs), which have emerged across the country and in Pennsylvania.

Tackling the root cause of construction's mental health

University of Warwick researchers have shaped a new Mental Health Joint Code of Practice, launched by the Construction Leadership Council, that presents solutions to poor mental health in construction, which is one of the most significant risks facing the construction industry. The Office for National Statistics says the suicide rate for men in U.K. construction is nearly four times the national average. Yet mental health harm is not inevitable; it is the result of decision-making around how construction work is designed, planned and led.

Invisible chemical landscapes shape life

Plants, animals and microorganisms constantly communicate through chemical signals. A research team has now shown that these signals merge in the environment to form complex "chemical landscapes" that have effects far beyond those of their individual components. Published in Nature Ecology & Evolution, the findings open new perspectives on understanding biodiversity, ecosystems and the impacts of global environmental change. The study was coordinated by Bielefeld University.

Digital twin predicts Alaska permafrost changes using real-time sensors and AI

Communities around the world have adapted to live on the year-round frozen soil of frigid environments, such as in the Arctic. However, rising temperatures have introduced a new challenge: What happens when the ground under houses and roads begins to melt?

SpaceX Dragon Prepares for Undocking and Return to Earth

The unpiloted SpaceX Dragon spacecraft will undock at approximately 12:05 p.m. EDT from the forward-facing port of the station’s Harmony module and fire its thrusters to move safely away from the orbital complex. The post SpaceX Dragon Prepares for Undocking and Return to Earth appeared first on NASA Science.

Potatoes benefit when two soil bacteria team up

Researchers at Umeå University have shown that two soil bacteria can work together to influence potato development. The bacterial partnership triggered distinct responses in potato plants and was associated with earlier tuber initiation and improved yield under greenhouse conditions. The findings suggest that combinations of beneficial soil bacteria could become a valuable tool for potato growers in the future.

2,700-year-old standing stone may provide fresh evidence for King Hezekiah's religious reforms

A new study by Prof. Avraham Faust of Bar-Ilan University's Department of General History presents new evidence that may shed light on one of the most debated questions in the study of Israelite religion: Did King Hezekiah's religious reforms actually occur, and did they transform religious practices throughout the Kingdom of Judah?

Depression may rewire how kids pay attention to emotional faces

A smile. A frown. The faces a child pays closer attention to might offer insight into their mental health. Depression may shape how much children pay attention to emotional expressions—sad or happy faces—and those changes appear to depend on whether the child has a family history of depression, according to a first-of-its-kind study from Binghamton University, State University of New York.

Major sporting events could offer a public health role for nursing students

As Toronto hosts the 2026 FIFA World Cup, the city is welcoming large crowds, international visitors and volunteers into stadiums, transit hubs, fan spaces and public areas. For many people, the World Cup is about soccer, national pride and global celebration. But for host cities, it's also a public health event.

When glaciers vanish, so does the hidden life they support

We often hear about glacier melting and predictions of what climate change could do. But very little is mentioned about the effects on ecosystems or the animals that call them home. To redress some of this imbalance, an international team of researchers set out to map this hidden biodiversity. Their findings are published in the Proceedings of the National Academy of Sciences.

Public school closings in Chicago linked to more gun violence in nearby neighborhoods

In 2013, Chicago Public Schools closed 49 elementary schools—the largest mass public school closure in U.S. history at the time. A new study from researchers at the University of Chicago and the Johns Hopkins Bloomberg School of Public Health, published in Social Science & Medicine, shows that, in addition to limiting access to education, the school closures also led to increases in gun violence.

Ultra-rare gene variant appears as schizophrenia or autism in one island family

For most of a century, psychiatry has kept its disorders in separate rooms. Schizophrenia in one. Bipolar disorder in another. Autism somewhere down a different corridor entirely. The arrangement was orderly, and it organized clinics and insurance codes and the words that families carried home from the appointment. It was also, as anyone who ever sat with real patients understood, a little bit of a fiction at the edges. The diagnoses were tidy. The family histories were not.

'Geriatric' butterfly species lives nearly three times as long as their relatives

A tropical butterfly has evolved an ingenious anti-aging strategy by delaying the aging process, enabling it to live far longer than its closest relatives, according to a new University of Bristol-led study published in Nature Communications. Found throughout the tropical rainforests of South and Central America, butterflies of the Heliconius tribe are among the longest-lived species ever recorded and could provide a new model for studying the biology of longevity.
