Medical Xpress / Largest study supports three courses of radiation for children with deadly brain tumor
Children with one of the deadliest forms of brain cancer may benefit from an additional course of radiation therapy after their disease returns, according to new research from the Icahn School of Medicine at Mount Sinai. ...
Tech Xplore / Why adding AI agents to a system sometimes reduces its performance
Computer scientists worldwide have been developing a wide range of artificial intelligence (AI) systems. Some of these systems rely on an individual AI agent, while others consist of multiple interacting agents that exchange ...
Phys.org / Electric fish keep from blinding themselves with these brain cells
The brain cells you see in the above image help an African fish decode electric signals to spot prey, scan its murky surroundings and communicate with its fellows. By rigorously mapping how these cells in the electrosensory ...
Phys.org / Exotic pines in the Southern Hemisphere grow faster and are more drought-resistant, study reveals
A new study published in the journal Nature reveals that conifers planted outside their native range in the Southern Hemisphere not only grow up to four times faster than those in the Northern Hemisphere but also show greater ...
Medical Xpress / Healthier fats linked to longer survival after prostate cancer diagnosis
Men diagnosed with nonmetastatic prostate cancer can generally expect to live for many years after their diagnosis. However, cardiovascular disease and other cancers remain important threats to their long-term health. For ...
Medical Xpress / Genetics of personality may shape more life outcomes than previously thought
An international consortium of researchers found that more than 1,200 different genetic variants are associated with the Big Five personality traits—and, surprisingly, these personality genetics are linked to dozens of life ...
Phys.org / Mammalian genes can combine to make previously unknown mRNAs and proteins
For decades, scientists have understood that each of the roughly 20,000 genes in the human body carries instructions for a single kind of protein. Now, researchers at Harvard Medical School have discovered that instructions ...
Medical Xpress / Genetic tests may miss reaction risk from drug prescribed to millions
A genetic marker already used to flag the risk of a life-threatening reaction to the antibiotic vancomycin also identifies patients at risk of that reaction to lamotrigine—and it is missing from the gene panels clinicians ...
Medical Xpress / GLP-1 treatment late in life extends lifespan in animal model
A study published in Nature has shown that the GLP-1 drug semaglutide extended the lifespan of older, healthy mice by tempering the detrimental effects of aging. Researchers at the University of California, Berkeley, directly ...
Phys.org / More than 120 molecular species found in giant cloud near Milky Way's center
Astronomers have discovered a second interstellar cloud near the center of the Milky Way that is extraordinarily rich in complex molecules, including several molecules associated with prebiotic chemistry. The newly studied ...
Phys.org / Peacock-like displays outpace antlers and tusks in evolutionary change, model suggests
Many animal species, ranging from peacocks and birds of paradise to some lizards, fish and beetles, display physical features or ornaments that can attract potential mates. These ornaments can include colorful plumage, elaborate ...
Medical Xpress / Musicians' brains stay one step ahead, study finds
Musicians don't just learn movement sequences faster; they predict what's coming next sooner, according to new research that also found newly formed motor memories can be disrupted by seeing different visual sequences shortly ...
