Mice that had experienced strokes were more likely to recover the ability to use a front paw if their whiskers were clipped following a stroke. Trimming the whiskers deprives an area of the mouse’s brain from receiving sensory signals from the animals’ whiskers. And it leaves that area of the brain more plastic – or receptive to rewiring to take on new tasks.
Researchers have identified cells that indicate anxiety in the brains of mice.
Scientists at the Department of Energy’s SLAC National Accelerator Laboratory are using X-ray light to observe and understand how the process of making metal parts using three-dimensional (3-D) printing can leave flaws in the finished product – and discover how those flaws can be prevented.
American University President Sylvia M. Burwell today launched AU’s Plan for Inclusive Excellence, a far-reaching effort to build a truly inclusive community at the University.
Bursting oxygen-filled microbubbles in breast cancer makes tumors three times more sensitive to radiation therapy in preliminary tests with animal models of the disease
Engineers hope that soon athletes will have "digital twins" of their heads, baseline representations of skull, vasculature and brain that can help to predict where injuries might occur and diagnose them when they do.
People with Alzheimer’s disease have disturbances in their internal body clocks that affect the sleep/wake cycle and may increase risk of developing the disorder. Researchers at Washington University School of Medicine in St. Louis have found that such circadian rhythm disruptions also occur much earlier in people whose memories are intact but whose brain scans show early, preclinical evidence of Alzheimer’s.
West Virginia University researchers are taking an innovative approach to develop a more sustainable and economical pest control solution.
“See every obstacle as an opportunity in life.” That’s just some of the advice packed into a new campaign by Fight Colorectal Cancer featuring Texas Rangers third-base coach Tony Beasley.
Tiny particles fuel powerful storms and influence weather much more than has been appreciated, according to a study in the Jan. 26 issue of the journal Science. The tiny pollutants – long considered too small to have much impact on droplet formation – are, in effect, diminutive downpour-makers.
A large international research team, led by Israel Hershkovitz from Tel Aviv University and including Rolf Quam from Binghamton University, State University of New York, has discovered the earliest modern human fossil ever found outside of Africa. The finding suggests that modern humans left the continent at least 50,000 years earlier than previously thought.
Teresa Woodruff explains the fight for female inclusion in scientific research.CHICAGO - Women’s health research got a federal and local boost with the declaration of a national Women’s Health Research Day to coincide with the 2nd Annual Symposium on Sex Inclusion in Biomedical Research on Jan. 25.This event celebrates the second anniversary of the implementation of the landmark policy set forth by the National Institutes of Health (NIH) requiring investigators to consider sex as a biological variable.
On the hunt for genes involved in regenerating critical nerve fibers called axons, biologists at the University of California San Diego came away with a surprise: The discovery of a new genetic pathway that carries hope for victims of traumatic injuries—from stroke to spinal cord damage.
A newly discovered family of viruses appears to play a major role in killing marine bacteria and maintaining the ocean’s ecology. Preliminary evidence suggests that related bacterial viruses also occur in the human gut. The study, by researchers at Albert Einstein College of Medicine and Massachusetts Institute of Technology (MIT), was published online today in the journal Nature.
Through the haze of a sonogram screen, an expectant mother catches a glimpse of the growing baby within her. The outline of a nose, chin and head, instantly recognizable as a tiny human, brings to life what parents, until then, could only imagine. Biologists, too, aim to bring their scientific discoveries to life by creating three-dimensional models—at the atomic level—of the inner workings of cells
People with the rare genetic disease primary ciliary dyskinesia suffer repeated lung infections because they lack functional cilia, hairlike structures that sweep mucus through the airways. Most people have errors in the molecular motor that powers the cilia. But some have errors in non-motor proteins. Now, Washington University School of Medicine in St. Louis researchers report that mutated non-motor proteins cause disease by assembling the motor incorrectly. The findings suggest new routes to drug discovery.
A University of Arkansas invention has the potential to change the way we produce and consume energy. A technology commercialization company has licensed the patent for this technology and is working with physics professor Paul Thibado on to develop a prototype.
At the peak of its 50th anniversary, UNLV’s Harrah College of Hospitality is ringing in the New Year – and the new semester – with the opening of its state-of-the-art academic building, Hospitality Hall.
Scientists have revealed the atomic-level structure of a molecular complex responsible for modifying proteins, possibly paving the way for the development of new medications for cancer and a host of other diseases.
If you call 911 due to a hypoglycemic episode there is a roughly 3 in 4 chance the emergency medical responder will be unable to give you glucagon
