At Penn, collaboration is as ingrained in the culture as innovation. And, it turns out, some teams end up having quite the crew. One specific group—working to detect early stage ovarian cancer—maintains experts spanning obstetrics and gynecology, chemistry, physics, and veterinary care. It also includes human’s best furry friends: dogs. As […]

Regular physical activity may help older women increase their mobility, but muscle strength and endurance are likely to succumb to the effects of frailty if they haven’t also been doing resistance training. That is according to the findings of a cross-sectional study led by the University at Buffalo and published […]

Using a homemade, high-tech microscope, scientists at the University of Virginia School of Medicine have revealed how a cancer-causing virus anchors itself to our DNA. That discovery could pave the way for doctors to cure previously incurable diseases by flushing out viruses, including HPV and Epstein-Barr, that now permanently embed […]

A remote command could one day send immune cells on a rampage against a malignant tumor. The ability to mobilize, from outside the body, targeted cancer immunotherapy inside the body has taken a step closer to becoming reality. Bioengineers at the Georgia Institute of Technology have installed a heat-sensitive switch […]

Research led at the Yale School of Public Health have found that the majority of published papers analyzing the cost-effectiveness of a widely used test for breast cancer used a study design that can increase bias. Oncotype DX, a gene-expression profiling test, is used in clinical care to guide chemotherapy […]

But platelets also release so-called growth factors that help repair soft tissues – blood vessels, skin, muscle, tendons – and recruit other cells to speed the healing process. Those capabilities have made platelet-rich plasma an emerging treatment option for certain joint injuries and post-operative therapies. Now researchers from the University […]

Exposure to a toxin primarily found in sheep could be linked to the development of multiple sclerosis (MS) in humans, new research suggests. Carried out by the University of Exeter and MS Sciences Ltd., the study has found that people with MS are more likely than other people to have […]

While older drivers as a group have a relatively high rate of car crashes, few validated tools exist to evaluate an individual’s crash risk and to help older adults make the life-altering decision to give up their car keys. Aiming to better understand how adults’ crash risk changes over time, […]

A rear-ender in which the driver’s head slams against the steering wheel or a helmet-to-helmet tussle with an opponent on the football field may increase one’s risk for Parkinson’s disease if concussion results, say researchers from UCSF and the San Francisco Veterans Affairs Medical Center. In their study, which publishes […]

A new scientific study shows that exposure of preschool children to bright electric light in the evening suppresses melatonin production almost completely, an important addition to the growing body of research in this area. Melatonin suppression is a marker of disruption of our circadian rhythms. Ten kids, ages 3 to 5, were […]

Scientists have identified the molecular mechanism that leads to the death of neurons in amyotrophic lateral sclerosis (also known as ALS or motor neurone disease) and a common form of frontotemporal dementia. Writing in Cell, the researchers from the University of Cambridge and University of Toronto also identify potential therapeutic targets for these currently incurable […]

Back in 2013, researchers achieved human brain organoids for the first time, which they had eventually managed to induce to form structures like those seen in the brains of foetuses. The problem with the brainy organoids is their short life-span. “In our hands, the organoids stop growing around five weeks,” […]
