PHILADELPHIA -- For years cardiologists have threaded hair-like surgical instruments through arteries in the wrist, as an access point to perform procedures on the heart. For procedures in the brain, however, neurosurgeons more commonly thread instruments through arteries at the groin - a transfemoral approach.
Needing to ride in a wheelchair can put the brakes on myriad opportunities - some less obvious than one might think. New research from Michigan State University sheds light on the bias people have toward people with disabilities, known as "ableism," and how it shifts over time.
Contrary to popular belief, the findings suggest that biases toward people with disabilities increase with age and over time, but that people are less likely to show how they really feel publicly.
Great holiday, fantastic party, adorable children, incredible food: everyone shows their life in the best light on social networks. Those who take a look around on such sites can find that their self-esteem takes a hit as it seems as though everyone is better than them. Users who use social networks passively, i.e. do not post themselves, and tend to compare themselves with others are in danger of developing depressive symptoms. This is what a team of psychologists at Ruhr-Universität Bochum (RUB) led by Dr. Phillip Ozimek discovered.
In a world where energy consumption is on the rise, our only hope is the development of new energy-generation technologies. Although currently used renewable energy sources such as wind and solar energy have their merits, there is a gigantic, permanent, and untapped energy source quite literally under our noses: geothermal energy.
Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these "micro-bristle-bots" might work together to sense environmental changes, move materials - or perhaps one day repair injuries inside the human body.
New research from a randomised clinical trial published today in The Lancet and funded by the National Institute for Health Research (NIHR) shows that partial knee replacements (PKR) are as good as total knee replacements (TKR), whilst being more cost effective.
Software that purportedly reads emotions in faces is being deployed or tested for a variety of purposes, including surveillance, hiring, clinical diagnosis, and market research. But a new scientific report finds that facial movements are an inexact gauge of a person's feelings, behaviors or intentions.
Why are languages so different from each other? After comparing more than two thousand languages, scientists noticed that languages with more speakers are usually simpler than smaller languages. For instance, most English nouns can be turned into plurals by simply adding -s, whereas the German system is notoriously irregular. Linguists have proposed that languages adapt to fit different social structures.
NEWPORT, Ore. - Scientists can predict where and when blue whales are most likely to be foraging for food in the California Current Ecosystem, providing new insight that could aid in the management of the endangered population in light of climate change and blue whale mortality due to ship strikes, a new study shows.
What The Study Did: This multicenter study used in vivo β-amyloid cerebrospinal fluid, a biomarker of Alzheimer disease, and positron emission tomography findings to track progression of Alzheimer disease over six years among study participants.
Authors: Niklas Mattsson, M.D., Ph.D., and Oskar Hansson, M.D., Ph.D., of Lund University in Malmo, Sweden, are the corresponding authors.

The Cerrado is the largest savanna region in South America, but compared to the Amazon Forest to the North, it does not attract much attention. It is home to an incredible diversity of large mammal species including jaguar, the endangered maned wolf, the giant anteater, giant armadillo, and marsh deer, as well as more than 10,000 species of plants, almost half of which are found nowhere else on Earth. Despite its importance as a global biodiversity hotspot, it is one of the most threatened and over-exploited regions in Brazil.
Leukemia stem cells protect themselves against the immune defense by suppressing a target molecule for killer cells. This protective mechanism can be tricked with drugs. In the journal "Nature", scientists from Basel, Tübingen and Heidelberg describe the new therapeutic approaches that can possibly be derived from these results.
(MEMPHIS, Tenn.--July 17, 2019) What can a family of rare inherited disorders teach scientists about more common health problems like fibrosis? Plenty, based on research led by St. Jude Children's Research Hospital scientists that appears today in the journal Science Advances.
Swapping short car trips for walking or biking could achieve as much health gain as ongoing tobacco tax increases, according to a study from the University of Otago, New Zealand.
Lead author Dr Anja Mizdrak, of Otago's Burden of Disease Epidemiology, Equity, and Cost-Effectiveness Programme (Department of Public Health), says transport has a major impact on population health.
Scientists have visualised the electronic structure in a microelectronic device for the first time, opening up opportunities for finely-tuned high performance electronic devices.
Physicists from the University of Warwick and the University of Washington have developed a technique to measure the energy and momentum of electrons in operating microelectronic devices made of atomically thin, so-called two-dimensional, materials.
