Medical Xpress / Prefrontal cortex reaches back into the brain to shape how other regions function, study reveals
Vision shapes behavior, and a new study by MIT neuroscientists finds behavior and internal states shape vision. The research, published in Neuron, finds in mice that, via specific circuits, the brain's executive control center, ...
Medical Xpress / Cracking gastric cancer's metabolic code: Blocking cholesterol pathways slows tumor growth by 65% in mice
A research team from the LKS Faculty of Medicine at the University of Hong Kong (HKUMed) has made a breakthrough in gastric cancer research, revealing how the "second brain"—nerves in the digestive system, also known as ...
Medical Xpress / A hospital-acquired bacterium can travel from lungs to gut, raising sepsis risk
A hospital-acquired bacterium that causes serious infections can move from the lungs to the gut inside the same patient, raising the risk of life-threatening sepsis, new research reveals.
Medical Xpress / Scientists identify five structural eras of the human brain over a lifetime
Neuroscientists at the University of Cambridge have identified five "major epochs" of brain structure over the course of a human life, as our brains rewire to support different ways of thinking while we grow, mature, and ...
Medical Xpress / HER2-targeted therapy shows promising results in rare bile duct cancers
Zanidatamab, a bispecific HER2-targeted antibody, delivered clinically meaningful and durable responses for patients with HER2-positive biliary tract cancer (BTC), according to final results from the HERIZON-BTC-01 clinical ...
