Medical Xpress / How new information triggers the brain to navigate changing environments
In a paper published in the journal Nature Communications, biomedical engineers have shown how two brain regions quickly adapt to shift focus from one planned destination to another.
Medical Xpress / Scientists reveal neural mechanism that could lead to better pain relief
Researchers have pinpointed the precise pathway in the brain that suppresses pain in times of threatening situations.
Medical Xpress / Researchers find that genetic ancestry influences how gene mutations impact cancer prognosis
Investigators have unveiled for the first time that changes in certain genes affect an aggressive cancer, T-cell acute lymphoblastic leukemia (T-ALL), differently depending on genetic ancestry.
Medical Xpress / Researchers develop first test of cure for Chagas disease
Researchers at the University of Georgia's Center for Tropical and Emerging Global Diseases have developed the first test to determine whether treatment for Chagas disease was effective. The study is published in the journal ...
Medical Xpress / Some cancer cells just won't commit: Why that might be good news for neuroblastoma patients
Neuroblastoma is a cancer that affects the sympathetic nervous system of children. It is unusual among cancers because it shows a range of outcomes: from aggressive, potentially fatal progression to a unique phenomenon where ...
Medical Xpress / Sugary drinks in older age show no effect on dementia, large study finds
Zhejiang University School of Medicine in China, along with American researchers, has found no link between late-life intake of sugar or artificially-sweetened beverages and all-cause dementia in older U.S. adults.
Medical Xpress / New study locates neuron clusters that help the brain repay sleep debt
Sleeping deeply into the afternoon after an all-nighter or a late night out is one way the body repays its sleep debt. The sleep-wake cycle is regulated by a homeostatic process in which the body continuously adjusts its ...
Medical Xpress / Sex-specific pathway driving melanoma metastasis discovered, with implications across female cancer treatments
Institut Curie researchers have identified a sex-specific molecular pathway connecting E-cadherin loss, estrogen receptor-α (ERα), and GRPR, contributing significantly to increased melanoma metastasis in women.
Medical Xpress / A universal sleep pattern could help strengthen and separate memories
Although we know sleep is essential to our physical and mental well-being, it remains an incredibly enigmatic behavior, scientifically speaking. Researchers at the University of Michigan, however, may have developed a new ...
Medical Xpress / Zoning out could be beneficial—and may actually help us learn faster
Aimlessly wandering around a city or exploring the new mall may seem unproductive, but new research from HHMI's Janelia Research Campus suggests it could play an important role in how our brains learn.
Medical Xpress / Stick-on sleep monitor promises smarter, more accurate detection of sleep disorders
A team of Northwestern investigators have developed a wearable and wireless sleep monitoring device that provides an in-depth analysis of different sleep stages and may improve the detection of sleep disorders, detailed in ...
Medical Xpress / Genetic cause for rare childhood brain developmental disorder found
University of Otago–Ōtākou Whakaihu Waka has led international research uncovering a new genetic cause for a rare developmental disorder that profoundly impacts brain growth and function in children.
