Medical Xpress / A single enzyme keeps neuroblastoma alive—how to shut it off
The tumor begins before birth. Somewhere in the developing fetus, neural crest cells that should have matured into adrenal tissue or sympathetic ganglia take a wrong turn, and a child is born harboring a malignancy that may ...
Medical Xpress / New study finds a missing link in how the brain regulates appetite
When the stomach is full, how does the brain know to stop eating? Scientists long assumed the answer lies mainly with neurons, the brain's primary signaling cells. But a new study published in the Proceedings of the National ...
Phys.org / Glucose transport may hinge on a fleeting transition-like state
Stockholm University and SciLifeLab researchers have uncovered how glucose transporters move nutrients into cells, bridging a long-standing gap between structure and function in membrane biology. "Our study shows that these ...
Tech Xplore / Latest Anthropic AI model finds cracks in software defenses
Anthropic on Tuesday said its yet-to-be-released artificial intelligence model called Claude Mythos has proven keenly adept at exposing software weaknesses.
Medical Xpress / Extra chromosomes may seed childhood leukemia years before disease, study suggests
B-cell acute lymphoblastic leukemia is the most common form of childhood cancer. In this type of cancer, which affects blood cells, one of the most common abnormalities is the presence of cells with an excess of chromosomes ...
Phys.org / Phengite identified as key carrier of halogens into Earth's deep mantle
Surface volatiles—chemical substances that easily become gases or fluids at relatively low temperatures and pressures—are transported into Earth through subduction zones, with some being transported into the deep mantle and ...
Tech Xplore / Explainability is a must for older adults to trust AI, study shows
Voice-activated, conversational artificial intelligence (AI) agents must provide clear explanations for their suggestions, or older adults aren't likely to trust them. That's one of the main findings from a study by AI Caring ...
Phys.org / Sinking land drives coastal flood risk on densely populated Java Island
A new study published in Science Advances reveals that sinking land—not just rising oceans alone—will be the main cause of future coastal flooding along Indonesia's densely populated Java Island, putting millions at risk ...
Phys.org / How NASA's Artemis II mission rediscovered the majesty and mystery of the moon
On April 10, Artemis II—humanity's first mission to the moon in more than half a century—will draw to a close when the Orion capsule carrying four crew members detaches from its service module.
Phys.org / 3D-printed 'spanlastics' could change how cancer drugs reach tumors
University of Mississippi research offers hope that cancer drug therapies packaged in 3D-printed carriers could deliver medication directly to tumors while reducing many of the side effects that cancer patients endure. In ...
Phys.org / 3D microscopy reveals how a tick-borne virus reshapes human cells to replicate
Researchers at Umeå University show how tick-borne viruses remodel human cells into virus factories, using an advanced microscopy method. The findings provide new insight into how the virus replicates and matures, knowledge ...
Phys.org / A layered approach sharpens brain signals in optical imaging
Near-infrared spectroscopy, or fNIRS, offers a way to monitor brain activity without surgery or radiation by tracking changes in blood flow and oxygenation. Light sources placed on the scalp send near-infrared light into ...
