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 ...
Medical Xpress / Leukemia study restores silenced gene in mice. Could it point to new treatments for humans?
A key cancer-fighting gene in leukemia is switched off—not broken—and scientists from The Jackson Laboratory (JAX) have found a way to switch it back on. In a study published in Science Translational Medicine, the team reveals ...
Medical Xpress / Using augmented reality to motivate prosthesis training
Artificial limbs look and function more like real limbs than ever before—but that's only helpful if they are used as intended. One of the main reasons amputees give for not using their body-powered prosthesis is a lack of ...
Medical Xpress / Proof of visual perception's fundamental mechanisms: 1981 Nobel Prize-winning model confirmed correct
A scientific dispute spanning six decades about fundamental mechanisms of visual perception in mammals has now been settled. Researchers at TUM have succeeded in observing the visual information flow from neuron to neuron. ...
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 / Reprogramming 'gatekeeper' immune cell may boost cancer immunotherapy
St. Jude Children's Research Hospital scientists have discovered how tumors disable immune "gatekeeper" cells that alert the rest of the immune system to the presence of cancer—and how restoring their energy production can ...
Medical Xpress / Uncontrolled scarring: Study reveals the cell sensor that turns healing into harm
Fibrosis is the body's way of patching up damage—a bit like fixing a pothole. When skin is cut or a muscle is injured, fibroblast cells rush in to make fibronectin and collagen, which are two major extracellular matrix proteins ...
Medical Xpress / How disinfectants influence microbes across hospital rooms
Just because a topical antiseptic is swabbed on the skin doesn't mean it stays on the skin. In a new study, Northwestern University scientists studied how a powerful antiseptic, called chlorhexidine, affects bacteria in hospital ...
Medical Xpress / How pancreatic tumors thwart an iron-driven demise
Tumors driven by cancer-driving KRAS mutations are often susceptible to ferroptosis, a type of cell death that can be harnessed for cancer therapy. Given that more than 95% of pancreatic ductal adenocarcinomas (PDACs) harbor ...
Medical Xpress / Sugary drink taxes are not effective in fast-food settings, drive-through analysis suggests
Taxes on sugary drinks had no effect on beverage calorie purchases from fast-food chain restaurants in the U.S., according to a new study by Brian Elbel and Pasquale Rummo from NYU Grossman School of Medicine and colleagues ...
Medical Xpress / Innovative targeted therapy halts prostate cancer spread to the bone
New findings from VCU Massey Comprehensive Cancer Center and the VCU Institute of Molecular Medicine (VIMM), published in Pharmacological Research, show that an innovative drug effectively prevents prostate tumors from spreading ...
Medical Xpress / AI-powered portable eye scanner expands access to low-cost community screening
Imagine being able to assess how healthy the front of our eyes are not only in hospitals, but also in remote eye-screening camps, elderly-care facilities, pharmacies, or even train stations. That is the future a research ...
