Society’s expectations about gender roles alter the human brain at the cellular level, according to a paper published by a group of neuroscience researchers at Georgia State University. “We are just starting to understand and study the ways in which gender identity, rather than sex, may cause the brain to differ in males and females,” […]
Emory researchers have found that adding good bacteria into the intestines can guide the development of the enteric nervous system, also called “the gut brain,” while increasing intestinal motility, or movement of the digestive tract, in a mouse model. The results are good news for medical conditions such as irritable bowel syndrome, Parkinson’s disease, autism […]
Perpetually hungry, worms are strategic when it comes to searching for food. The microscopic roundworm Caenorhabditis elegans, or C. elegans, is known to spend up to 20 minutes seeking out snacks in its immediate surroundings before endeavoring to look elsewhere. Now, Rockefeller scientists have identified circuits in the C. elegans brain that underlie this behavior. […]
Deadly ‘zombie’ deer disease could spread to humans A deadly ‘zombie’ deer disease could possibly spread to humans, experts are warning. Republican Rep. Ralph Abraham isn't going to wait for the deadly, so-called “zombie” deer disease to spread to his home state of Louisiana before taking action. Abraham, who represents the state’s 5th congressional district, […]
Young children are particularly vulnerable to the effects of tobacco smoke and other environmental toxins, but their exposure is often difficult and expensive to measure. The results of those measurements, however, can be crucial for research on the success of preventative measures. Jenny Quintana and her research team at San Diego State University’s School of […]
Scientist have long known that bacteria in the intestines, also known as the microbiome, perform a variety of useful functions for their hosts, such as breaking down dietary fiber in the digestive process and making vitamins K and B7. Yet a new study unveils another useful role the microbiome plays. A team of researchers from […]
Avid animal lovers Kristen and Mike M. both work in animal-related fields and were already proud pet parents to two cats. The couple loved the idea of adding a dog friend to their family and talked about it extensively. Specifically, they were considering rescuing a pit bull with an energetic personality to take on outdoor […]
Virginia Tech Carilion Research Institute scientists have shown that mutations in specific genes that destroy motor neurons and thereby cause the devastating effects of amyotrophic lateral sclerosis— also known as ALS or Lou Gehrig’s disease—also attack sensory neurons. The discovery in today’s Scientific Reports indicates that studying sensory neurons could provide new mechanistic insights to […]
NIBIB-funded researchers have transformed T cells into drug factories engineered to find cells carrying specific diseases in the body—and then produce therapeutic proteins localized to the diseased cells. Senior author Parijat Bhatnagar, Ph.D., director of cell-based medicine at the SRI International Center for Chemical Biology, Menlo Park, California, and his colleagues engineered the T-cell “biofactories” […]
More than 100 patients afflicted by mysterious illnesses have been diagnosed through a network of detective-doctors who investigate unidentified diseases, reports a study conducted by scientists at the Stanford University School of Medicine and multiple collaborating institutes. The long-awaited diagnoses are the fruits of the Undiagnosed Disease Network, a program created by the National Institutes […]
