Medical Xpress / Keeping neurons on the right path: Scientists identify key driver of cortical layering during brain development
The cerebral cortex, the brain's outermost region responsible for higher cognitive functions, depends on a highly ordered, layered structure. Its proper development requires newly generated neurons to migrate to precise locations ...
Medical Xpress / Single daily pill shows promise as replacement for complex, multi-tablet HIV treatment regimens
A new, daily oral tablet that combines two current HIV treatment medications, bictegravir and lenacapavir (BIC/LEN), could effectively replace more complicated HIV treatment regimens used by people living with HIV who are ...
Medical Xpress / Neurosurgeons are really good at removing brain tumors—they're about to get even better
When removing cancerous tissue in the brain, neurosurgeons often use "awake brain mapping" to minimize the risk of causing unintended disruptions to a patient's quality of life while removing as much tumor as possible. This ...
Medical Xpress / Cell signaling step sharpens understanding of how the body responds to exercise's energy demands
Researchers have investigated the role of a certain enzyme in regulating energy in muscle and exercise performance for decades, but a new study by Virginia Tech scientists has identified more precisely than ever how this ...
Medical Xpress / Long-term brain effects of COVID-19 vs. flu: Study reveals key differences
Even a mild case of COVID-19 or the flu can impact the body long after the fever and cough fade, according to new Tulane University research that may help explain why some people struggle to feel fully recovered weeks or ...
Medical Xpress / Vitamin B7 reveals a new metabolic weak spot in some cancers
A research group at the University of Lausanne (Unil) has identified a new mechanism that exposes the vulnerability of tumor cells when they are deprived of vitamin B7. The ability of cells to adapt to fluctuations in nutrient ...
Medical Xpress / Yawns in healthy fetuses might indicate mild distress
Even in the womb, where all oxygen is provided by the parental placenta, fetuses can—and do—yawn. More yawns during observation were associated with a lower weight at birth—potentially indicating mild fetal stress in ...
Medical Xpress / In Rett syndrome, leaky brain blood vessels traced to microRNA
MIT researchers have discovered that two common genetic mutations that cause Rett syndrome each set off a molecular chain of events that compromises the structural integrity of developing brain blood vessels, making them ...
Medical Xpress / 'Off the shelf' immunotherapy could get a lift from gene-edited natural killer cells
Since scientists first discovered that human immune cells could be modified to become cancer-fighting agents, they've been trying to engineer a cell that's effective against solid tumors, which account for the vast majority ...
Medical Xpress / Gallbladder cancer could soon be detected in blood
Researchers at Tezpur University in Assam, India, working with scientists at the University of Illinois Urbana-Champaign, have identified distinct chemical signatures in blood that could help detect gallbladder cancer earlier. ...
Medical Xpress / Civilians face increasing harm from deadly explosive weapons, 17-country study finds
A University of Queensland study has found that almost 90% of people killed and injured by landmines and similar weapons are civilians. Dr. Stacey Pizzino from UQ's School of Public Health, together with her research team, ...
Medical Xpress / AI, monkey brains, and the virtue of small thinking illuminate how the brain processes sight
What does it take to make AI that can pass as human? Try massive clusters of supercomputers. To build human-like intelligence, computer scientists think big. However, for neuroscientists who want to understand how real brains ...
