Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
BOSTON (Embargoed until 11 AM EDT, June 27, 2016)--Blood levels of seafood and plant-based omega-3 fatty acids are moderately associated with a lower risk of dying from heart attacks, according to a new epidemiological study, published today in JAMA Internal Medicine, led by Liana C. Del Gobbo, Ph.D., a postdoctoral research fellow in the division of cardiovascular medicine at Stanford University School of Medicine and senior author Dariush Mozaffarian, M.D., Dr.P.H., dean of the Friedman School of Nutrition Science and Policy at Tufts University in Boston.
COLUMBUS, Ohio--It's one of life's little annoyances: that last bit of shampoo that won't quite pour out of the bottle. Or the last bit of hand soap, or dish soap, or laundry detergent.
Now researchers at The Ohio State University have found a way to create the perfect texture inside plastic bottles to let soap products flow freely. They describe the patent-pending technology in a paper to appear in the journal Philosophical Transactions of the Royal Society on June 27.
ANN ARBOR, Mich. -- Even if you have what you might think of as good health insurance, your next hospital stay could cost you more than $1,000 out of your own pocket.
And that amount has gone up sharply in recent years - a rise of more than 37 percent just for straightforward hospital stays for common conditions.
Those striking statistics come from the first published analysis of actual out-of-pocket spending by people with private health insurance, most of it provided by employers. It's appearing today in the JAMA Internal Medicine, and being presented at the AcademyHealth Annual Research Meeting in Boston.
A new study from Western University is helping to explain why the long-term use of common anticholinergic drugs used to treat conditions like allergies and overactive bladder lead to an increased risk of developing dementia later in life. The findings show that long-term suppression of the neurotransmitter acetylcholine - a target for anticholinergic drugs - results in dementia-like changes in the brain.
She no longer recognizes a Van Gogh, but can tell you how to prepare a watercolor palette.
She can't recall a single famous composer, but knows the purpose of a viola's bridge.
She hasn't flown a plane since 2007, when viral encephalitis destroyed her hippocampus, the part of the brain used to form new memories and retrieve old ones. And she couldn't describe a single trip she's ever taken. But in detail, she'll list the steps needed to keep a plane from stalling and where to find the rudder controls.
Rabies virus (RABV) transmitted by dogs is responsible for an estimated 60,000 human deaths per year, especially in Asia and Africa. If humans bitten by a rabid animal are treated quickly, the disease can usually be prevented. Such post-exposure prophylaxis is expensive and should be reserved for bites from animals with confirmed infection, but testing dogs for rabies in resource-poor settings is challenging. A study published in PLOS NTDs reports that six commercially available rapid rabies tests--which could make testing dogs much easier--fail to reproducibly yield accurate results.
The passage of time can play cruel tricks on noble intentions. The person selected as the new United Nations (UN) Secretary-General later this year should keep this in mind as he or she evaluates how effectively the UN is responding to the challenges of the 21st century.
Those who go to a masked ball consciously slip into a different role, in order to avoid being recognized so quickly. Insects were already doing something very similar in the Cretaceous: They cloaked themselves in pieces of plants, grains of sand, or the remains of their prey, in order, for example, to be invisible to predators. An international research team, with participation from the University of Bonn, has now investigated such "invisibility cloaks" encased in amber. The custom-tailored "costumes" also permit conclusions about the habitat at the time. The results have now been published in the journal "Science Advances".
New work suggests Earth's ancient magnetic field was significantly different than the present day field, originating from several poles rather than the familiar two.
Earth generates a strong magnetic field extending from the core out into space that shields the atmosphere and deflects harmful high-energy particles from the Sun and the cosmos. Without it, our planet would be bombarded by cosmic radiation, and life on Earth's surface might not exist. The motion of liquid iron in Earth's outer core drives a phenomenon called the geodynamo, which creates Earth's magnetic field. This motion is driven by the loss of heat from the core and the solidification of the inner core.
Bremerhaven/Germany, 24 June 2016. The Siberian permafrost regions include those areas of the Earth, which heat up very quickly in the course of climate change. Nevertheless, biologists are currently observing only a minimal response in forest composition. In the places where, when considering the air temperature, pine and spruce forests should be growing, Siberian larch trees are still thriving. The cause of this paradox has been tracked using million-year-old bee pollen by scientists at the Alfred Wegener Institute, the University of Cologne, and international partner institutions. The results suggest that the intensity of the ice ages determined how quick the vegetation adapted to warmer climate periods.
A University of Exeter scientist has helped develop an innovative mathematical model for exploring why some individuals evolve to be genetically programmed to be nice, while others stay nasty.
Dr Sasha Dall, Senior Lecturer in Mathematical Ecology, and a team of international colleagues have designed a new mathematical framework for examining social behaviour in a range of different species that will help advance our understanding of the evolution of sociality.
One of the first clues pathologists look for in tissue from a newly diagnosed breast cancer patient is the estrogen receptor, a nuclear protein that converts hormonal messages in the bloodstream into instructions for the cell about how to behave. They also look for the presence of progesterone receptors, primarily to confirm that the estrogen receptor is active.
In the June 24 issue of Science Advances, however, researchers radically upgrade the significance of the progesterone receptor. They show that when exposed to estrogens and progestins, these receptor proteins interact with different sets of binding sites in the cell's chromosomes, with the progesterone receptor dramatically altering how estrogen receptors interact with the cell's DNA.
