After analyzing a database of geological records dated within the last 100,000 years, a team of scientists from the University of Bristol has discovered the average time between so-called volcanic super-eruptions is actually much less than previously thought.
Most older Americans take multiple medicines every day. But a new poll suggests they don't get -- or seek -- enough help to make sure those medicines actually mix safely. That lack of communication could be putting older adults at risk of health problems from interactions between their drugs, and between their prescription drugs and other substances such as over-the-counter medicines, supplements, food and alcohol.
Astronomers using the MUSE instrument on ESO's Very Large Telescope in Chile have conducted the deepest spectroscopic survey ever. They focused on the Hubble Ultra Deep Field, measuring distances and properties of 1600 very faint galaxies including 72 galaxies that have never been detected before. This groundbreaking dataset has already resulted in 10 science papers that are being published in a special issue of Astronomy & Astrophysics. This wealth of new information is giving astronomers insight into star formation in the early Universe.
The majority of patients were pain free after receiving a new image-guided pulsed radiofrequency treatment for low back pain and sciatica, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
Former National Football League (NFL) players are more likely to have enlarged aortas, a condition that may put them at higher risk of aneurysms, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA).
Osteoarthritis patients who received a steroid injection in the hip had a significantly greater incidence of bone death and collapse compared with control groups, according to new research presented today at the annual meeting of the Radiological Society of North America (RSNA).
There is no evidence that accumulation in the brain of the element gadolinium speeds cognitive decline, according to a new study presented today at the annual meeting of the Radiological Society of North America (RSNA).
Researchers from the Biogerontology Research Foundation, Insilico Medicine , Life Extension and other institutions announce the publication of a landmark study in the journal Aging on the identification of natural mimetics of metformin and rapamycin.
The next generation of electronic hardware security may be at hand as researchers at NYU Tandon School of Engineering introduce a new class of unclonable cybersecurity security primitives made of a low-cost nanomaterial with the highest possible level of structural randomness. Randomness is highly desirable for constructing the security primitives that encrypt and thereby secure computer hardware and data physically, rather than by programming.
A new method of examining the skin can reduce the number of animal experiments while providing new opportunities to develop pharmaceuticals and cosmetics. Chemical imaging allows all layers of the skin to be seen and the presence of virtually any substance in any part of the skin to be measured with a very high degree of precision.
More than 70 percent of senior drivers experience muscle and bone conditions that impact their driving. Inexpensive features like steering wheel covers help lessen the impact of these conditions, yet 90 percent of senior drivers do not make simple adjustments to their vehicle that can reduce crash risk. Crash prevention is critical since drivers 65+ are more than twice as likely as younger drivers to be killed when involved in a crash due to fragility.
State laws that restrict gun ownership among domestic abusers and others with violent histories appear to significantly reduce intimate partner homicides, indicates a groundbreaking national study led by a Michigan State University researcher.
A cross-section of opioid prescribers that typically do not prescribe large volumes of opioids, including primary care physicians, surgeons and non-physician health care providers, frequently prescribe opioids to high-risk patients, according to a new study by researchers at the Johns Hopkins Bloomberg School of Public Health.
Puerto Rican coqui frogs were accidentally introduced to Hawaii in the 1980s, and today there are as many as 91,000 frogs per hectare in some locations. What does that mean for native wildlife? Concerns that ravenous coquis could reduce the food available for the islands' native insect-eating birds, many of which are already declining, spurred researchers to examine the relationship between frog and bird populations -- but their results weren't what they expected.
Compared with the non-Hispanic white population, the urban American-Indian and Alaskan Native community was more likely to have lower survival rates following invasive prostate and breast cancer.
From a young age, we teach science to students all wrong.
Like history textbooks, science textbooks are filled almost exclusively with facts. Facts are fine -- and they are necessary to learn new facts -- but having a head full of facts does not make somebody a scientist. Arguably, in the age of Wikipedia, memorizing information is not an efficient use of time; instead, we can outsource our memory to the cloud and use our precious neurons for other things.
