Medical Xpress / Fear-learning circuit shows how stress disrupts brain's ability to suppress trauma
Fear is often thought of as a negative emotion but is actually a natural protective response to perceived threats or danger. It helps us survive. When we experience a situation that causes fear, it becomes stored in our brain ...
Tech Xplore / AI changes its behavior around authority... and that could be risky
Artificial intelligence doesn't just learn how humans talk. It may also be learning who gets listened to. A new study from researchers at the University of North Carolina at Chapel Hill found that large language models, the ...
Medical Xpress / Moms' responsiveness to their babies may predict later childhood psychiatric disorders
When mothers were slower to vocally respond to their 1-year-old children's vocalizations, the children were more likely to have been diagnosed with a psychiatric disorder by age 7, according to a study published in PLOS One ...
Medical Xpress / CAR T cell therapy targets key mutation driving rare blood cancers
A new form of CAR T-cell therapy has been designed to find and destroy the cancer-driving stem cells responsible for a group of blood cancers known as myeloproliferative neoplasms (MPNs), while leaving healthy blood cells ...
Phys.org / How giant earthquakes can form at fault planes where theory says they should not
A research group led by Satoshi Ide from the University of Tokyo has demonstrated that classic earthquake generation theory does not hold in areas where the angle at which a tectonic plate dips under another is sufficiently ...
Medical Xpress / Novel biomarker beats leading diagnostic blood test at predicting Alzheimer's progression
Small loops of genetic material may be strong indicators of imminent Alzheimer's disease (AD) symptoms. In a new study published in Nature Medicine, researchers showed that elevated levels of certain circular RNAs (circRNAs) ...
Phys.org / Earliest Americans specialized in megafauna hunting from Alaska to South America, analysis of 50 sites reveals
New research led by a University of Alaska Fairbanks archaeologist reveals that the earliest Native Americans had highly specialized diets, primarily hunting the largest animals on the landscape, and they targeted these megafauna ...
Phys.org / XMM-Newton and Chandra help revise distance to Milky Way's outer spiral arms
The European Space Agency's XMM-Newton and NASA's Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer spiral arms of our galaxy, the Milky Way. By measuring the distance ...
Tech Xplore / Horror-movie cue inspires wearable that turns robot movements into warning music
In horror movies, music is a dead giveaway. Tension builds with each note, and you brace for the inevitable jump scare. The same sense of anticipation has taken a leading role in an unlikely venue: a Georgia Tech robotics ...
Medical Xpress / A portable ultrasound system could make reliable breast imaging more accessible
For people at high risk of developing breast cancer, yearly mammograms may not be enough to detect tumors early. To make earlier diagnosis easier, an MIT team has developed portable detectors based on ultrasound, which could ...
Phys.org / Crystal-design principle reveals how competing molecular forces control structure, color and phase transitions
Organic molecular crystals can respond to external stimuli such as heat, light, and mechanical force, making them attractive candidates for next-generation functional materials. However, predicting how multiple intermolecular ...
Medical Xpress / Wearable device reveals how sleep changes from freshman to senior year for college students
Sleep is a fundamental aspect of human health that plays a crucial role in cognitive function, academic performance and social interactions. A study published in PLOS One by Yao Zhao at Temple University, U.S., and colleagues ...
