The work, by researchers at the U.S. Geological Survey, the University of California, Davis and the University of Colorado Boulder, is published in Science.

“If we don’t understand the underlying tectonic processes, it’s hard to predict the seismic hazard,” said co-author Amanda Thomas, professor of earth and planetary sciences at UC Davis.

Dr. Rowan Martindale, a paleoecologist and geobiologist at the University of Texas at Austin, was hiking through Morocco’s Dadès Valley in the Central High Atlas Mountains when an unusual detail in the rocks made her stop.

She and her team, including Stéphane Bodin of Aarhus University, were moving through the rugged landscape to investigate the ecology of ancient reef systems that once lay beneath the sea.

Reaching those reefs meant crossing repeated stacks of turbidites, sediments left behind by powerful underwater debris flows. Turbidites often preserve ripple marks, but Martindale noticed something else layered on top of the ripples. The surface showed small, irregular corrugations that did not fit what she expected to see.

Invisible earthquakes are revealing a hidden tectonic puzzle beneath California’s most dangerous fault zone.

A common belief is that compulsive behaviors trap people in a “habit loop” that takes over self-control. New research, however, suggests this explanation may be incomplete. For many years, compulsive behavior has been explained as people becoming trapped in a “habit loop” that takes over self-con

While the participants viewed these images, the researchers recorded their electrocardiographic signals. They measured the heart rate variability during a resting baseline period before the images appeared. They continued to measure it while the participants viewed the images. Finally, they measured it during a recovery period after the images were removed from the screen.

The results contradicted the team’s initial predictions. The data showed a distinct decrease in vagally mediated heart rate variability when participants viewed the bonding images. This physiological shift did not occur when they viewed the control images.

The reduction in variability during the bonding condition indicates a phenomenon known as “vagal withdrawal.” The parasympathetic system reduced its activity, similar to how the body reacts to stress or a demand for attention. This reaction suggests the body was mobilizing rather than relaxing.

Is it possible to spot personality dysfunction from someone’s everyday word use? My colleagues and I have conducted research that suggests you can, and often sooner than you might expect.

Whether in a quick text message, a long email, a casual chat with a friend, or a comment online, the words people choose quietly reveal deeper patterns in how they think, feel, and relate to others.

Everyone has personality traits – habitual ways of thinking, feeling and behaving. When these patterns become rigid, intense or disruptive, they can cause ongoing problems with emotions, sense of self and relationships.

A new study introduces a multilingualism calculator that quantifies how multilingual a person truly is, offering a clearer alternative to vague labels like “bilingual.”
