The good news for NFL players who sustain an injury to their anterior cruciate ligament (ACL) is that they’ll likely play again in the NFL. The bad news is, they’ll return with diminished performance on the field, concludes a study in the December issue of The American Journal of Sports Medicine.
The fruit fly gene “doublesex” is responsible for ensuring that male flies look male and females look female. New Brown University research led by biologist Michael McKeown shows that doublesex not only helps shape bodies but also shapes behavior, acting with together with the gene “fruitless” to guide flies’ courtship routines and responses. The finding, published in Nature Genetics, shows that sexual development in flies — and, perhaps, in humans — is a more complicated proposition than previously thought.
Scientists at Duke University Medical Center have visualized in a living animal how cells use a critical biological process to dice and splice genetic material to create unique and varied proteins.
Do the sounds of our native languages affect how we hear music and other non-language sounds? A team of American and Japanese researchers has found evidence that native languages influence the way people group non-language sounds into rhythms.
Black patients are more likely than white patients to prefer life-sustaining care when confronted with an incurable illness or serious mental and physical disabilities, according to a study by University of Rochester Medical Center researchers.
South Korean researchers have designed and built an inexpensive optical lens that collects light from a large area and produces a virtually distortion-free wide-angle image. Standing in contrast to commonly known “fisheye” lenses, which produce significant amounts of visual distortion, low-distortion wide-angle lenses can potentially improve image-based applications such as security-camera systems and robot navigation. The research appears in the December 1 issue of Applied Optics, a publication of the Optical Society of America.
The first human study using gene transfer to treat erectile dysfunction (ED) shows promising results and suggests the potential for using the technology to treat overactive bladder, irritable bowel syndrome and asthma, according to the researchers.
Living in a home with multiple dogs may help reduce an infant’s risk for developing wheezing in the first year of life, according to new research from the University of Cincinnati (UC).
Concerned that their soldiers are not being assessed on real-life situations, the US army is developing a virtual-reality aptitude test for recruits. Rather than using pen and paper in an exam, the recruits are placed in a virtual world where they are tested on their ability to solve tasks whilst navigating through different environments.
A University of Manchester researcher has developed a treatment for lower back pain using the patient’s own stem cells, which could replace the use of strong painkillers or surgery that can cause debilitation, neither of which addresses the underlying cause.
