Illustration: Eniola Odetunde/Axios Scientists are racing to learn more about the damage the novel coronavirus can do to the heart, lungs and brain. Why it matters: It’s becoming increasingly clear that some patients struggle with its health consequences — and costs — far longer than a few weeks. The big picture: The virus can have a […]
A drug used to treat chronic myeloid leukemia appears to be more effective at stopping a type of medulloblastoma in mouse models than existing treatments for the deadly pediatric brain tumor, reports a multi-institutional team led by researchers at Skaggs School of Pharmacy and Pharmaceutical Sciences at University of California San Diego. In the study, […]
When you experience severe pain, like breaking or shattering a bone, the pain isn’t just felt at the sight of the injury. There is an entire network of receptors in your body running from the site of the injury, through your nervous system, along the spine and into the brain that reacts to tell you […]
The structure of synaptic connections between neurons shapes their activity and function. Measuring a comprehensive snapshot of this so-called connectome has so far only been accomplished within tiny volumes, smaller than the head of a pin. For larger volumes, the long-range connectivity, formed by bundles of extremely thin but long fibers, has only been studied […]
For decades, biomedical researchers have used mouse behavior to study pain, but some researchers have questioned the accuracy of the interpretations of how mice experience pain. Now, Rutgers University-Camden neuroscientist Nathan Fried and colleagues from the University of Pennsylvania have developed a method that can more accurately gauge pain in mice, which could lead researchers […]
Researchers from RMIT University drew inspiration from an emerging tool in biotechnology — optogenetics — to develop a device that replicates the way the brain stores and loses information. Optogenetics allows scientists to delve into the body’s electrical system with incredible precision, using light to manipulate neurons so that they can be turned on or […]
When blood vessels in the brain rupture, or hemorrhage, and cause a stroke, large areas of the brain can be permanently damaged. Depending on the cause, some brain hemorrhages may hide underlying lesions that can be treated with surgery, embolization, radiation, or other treatments. Using MRI scans of patients diagnosed with intracerebral hemorrhage, clinical researchers […]
Scientists from The University of Queensland’s Diamantina Institute have revealed the difference between a stem cell and other blood vessel cells using gene-sequencing technology. Leading skin cancer and stem cell researcher Professor Kiarash Khosrotehrani said the findings provided evidence of how stem cells express genes that allow them to be identified within a blood vessel. […]
TBI is the leading cause of death and disability in people under 45 in developed countries. The primary injury, caused by the initial force from a fall or car accident for example, is followed by a secondary injury which develops in the minutes, hours and days afterwards. This secondary injury is largely responsible for the […]
A new study funded by the Department of Veterans Affairs (VA) and the Navy finds that veterans and service members with a history of combat-related mild traumatic brain injury — compared with those in a control group — have much higher levels of abnormally fast brain waves in a region that plays a key role […]
