One of the world's most important plate boundaries is older than previously thought‎

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.

Dominance-oriented views of masculinity widespread among young men, finds study‎

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.

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.

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.

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?

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?

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.
