Medical Xpress / Scientists uncover how the brain resolves emotional ambiguity
Scientists at the University of Oxford have demonstrated, for the first time, that a key emotional center deep in the human brain directly influences how we interpret ambiguous social cues. In a new study, published in Neuron, ...
Medical Xpress / Study reveals sharp vision comes from single cone cells in the fovea
The human eye can see with exceptional detail, allowing people to read fine print, recognize faces across the room, and take in the features in nature. Scientists have long debated how this sharp vision works at the cellular ...
Medical Xpress / Stress and addiction: New research reveals what connects them
Why do stressful moments so often push people toward habits like drinking? A new study from Texas A&M University offers one of the clearest answers yet, identifying a direct connection inside the brain that links stress to ...
Medical Xpress / Small molecule drug candidate offers hope for rare kidney stone disease with no current treatment
Scientists at the Buck Institute for Research on Aging have shown that an orally administered small molecule, N-propargylglycine (N-PPG), can completely prevent the formation of calcium oxalate kidney stones, protect against ...
Medical Xpress / A redesigned endoscope offers a new way to look for early signs of ovarian cancer
Ovarian cancer remains the deadliest gynecologic cancer, largely because it is rarely found early. Symptoms are often vague, and existing screening approaches—such as blood tests and transvaginal ultrasound—can miss the disease ...
Phys.org / Stretching metals can tune catalysis: A new method predicts energy shifts
Heterogeneous catalysis—in which catalysts and reactants are of different phases, e.g., solid and gas—is important to many industrial processes and often involves solid metal as the catalyst. Ammonia synthesis, catalytic ...
Phys.org / Quantum researchers engineer extremely precise phonon lasers
When lasers were invented in the 1960s, they opened new avenues for scientific discovery and everyday applications, from scanners at the grocery store to corrective eye surgery. Conventional lasers control photons—individual ...
Phys.org / Chaos shapes how meandering rivers change over time, research shows
Rivers are rarely the calm, orderly streams we imagine on maps. Over time, their winding paths—called meanders—shift, bend, and occasionally snap off in sudden "cutoff" events that shorten loops and reshape the landscape. ...
Phys.org / Webb eyes a pair of planet-forming disks
This month's NASA/ESA/CSA James Webb Space Telescope Picture of the Month offers us a two-for-one on brand new stars—with some potential planets thrown in as well. This visual highlights Webb's views of the protoplanetary ...
Medical Xpress / Sleep cleans the brain: Researchers develop fast, non-invasive way to measure the process
Sleep helps the brain to cleanse itself—and now this process can be measured in humans entirely noninvasively. Researchers at the University of Oulu have developed a method that allows the increased movement of brain fluids ...
Medical Xpress / Scientists discover how multiple sclerosis kills neurons
For decades, multiple sclerosis research has focused on myelin, the insulation around the brain's wiring. Scientists paid less attention to another loss that was happening in parallel: neurons in the cortex, the seat of higher ...
Medical Xpress / Zebrafish reveal new insights into the biology of autism
In recent decades, the zebrafish has become one of the most valuable model organisms in scientific research. For a variety of reasons, including their genetic similarities to humans, these tiny tropical fish have helped researchers ...
