After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
New research based on modern techniques suggests that recommendations for protein intake in healthy populations may be incorrect. In a paper just published in Applied Physiology, Nutrition, and Metabolism, an NRC Research Press journal (a division of Canadian Science Publishing), researchers put the focus on protein as an essential component of a healthy diet.
Protein helps people stay full longer, preserve muscle mass, and when combined with adequate physical activity, has the potential to serve as a key nutrient for important health outcomes and benefits.
It's not only how much protein you eat, it's the type of protein that is important.
If probiotics have success for boosting human health (that is in doubt, despite the number of papers capitalizing on the craze) it may depend partly upon the food or other material carrying the probiotics, according to a paper in Applied and Environmental Microbiology.
On the heels of a rather poorly constructed International Agency for Research on Cancer (IARC) analysis of organophosphate insecticides and pesticides a short while ago and a bizarre claim by the activist-funded group Moms Across America last year, the public is concerned about popular products like glyphosate. Mainstream journalism is no help, science is complex and when the $100 million Natural Resources Defense Council (famous for the Alar on apples manufactured scare) unleashes its public relations team on politically sympathetic journalists, claims are going to be repeated without much skepticism.
Galaxies in a cluster roughly 300 million light years from Earth could contain as much as 100 times more dark matter than visible matter, according to an Australian study. The research used computer simulations to study galaxies that have fallen into the Coma Cluster, one of the largest structures in the Universe in which thousands of galaxies are bound together by gravity.
"It found the galaxies could have fallen into the cluster as early as seven billion years ago, which, if our current theories of galaxies evolution are correct, suggests they must have lots of dark matter protecting the visible matter from being ripped apart by the cluster."
Is your favorite grocery store making you fat? According to new findings, a Grocer Retailer Scorecard may be an effective, healthy shopping tool that benefits both grocers and shoppers. "Grocers can benefit from encouraging healthy shopping practices because they can sell more perishable items like fruits and vegetables rather than tossing them in the dumpster after a few days," says lead researcher Brian Wansink, PhD, director of the Food and Brand Lab at Cornell University.
Titanium and gold are usually not magnetic and cannot be magnets – unless you combine them just so. Scientists at Rice University did so and discovered what is a first of its kind: an itinerant antiferromagnetic metal -- TiAu -- made from nonmagnetic constituent elements.
The research by the lab of Rice physicist Emilia Morosan has already been cited as a textbook example of how magnetism arises in metals. While the uses for this particular magnet have yet to be determined, the Rice discovery could enhance the scientific understanding of magnetism. This is not the kind of magnet one would stick to a refrigerator. Magnetic order only appears in TiAu when the metal is cooled to 36 kelvins, about minus 395 degrees Fahrenheit.
Challenging the idea that addiction is hardwired in the brain, a new study suggests that even a short time spent in a stimulating learning environment can rewire the brain’s reward system and buffer it against drug dependence.
Scientists tracked cocaine cravings in more than 70 adult male mice and found that those rodents whose daily drill included exploration, learning and finding hidden tasty morsels were less likely than their enrichment-deprived counterparts to seek solace in a chamber where they had been given cocaine.
A new paper says that Chinese grandparents tend to indulge, overfeed and protect grandchildren in their care from physical chores, thus increasing their risk of obesity. The underlying motive for the action of grandparents may be affection for their treasured grandchild and stems from their personal experiences, misunderstanding and poor recognition of the adverse health effects of childhood obesity.
A newly discovered family of chemical structures known as zeolites could increase the value of biogas and natural gas that contains carbon dioxide.
The zeolites -- crystalline aluminosilicates with frameworks that contain windows and cavities the size of small molecules -- can separate out carbon dioxide more effectively from fuel gases than those previously known.
Existing zeolites have widespread use in industrial processes that involve gas separation and catalytic conversion, for example to remove nitrogen and carbon dioxide from compressed air to generate oxygen in hospitals and airplanes. There is an ongoing search for new zeolites to add to those known, to augment the small number of different types used commercially.
A new study suggests that a single set of genes affects a person's perception of sweet taste, regardless of whether the sweetener is a natural sugar or a non-caloric sugar substitute.
Johanna Olson, MD, and her colleagues at Children’s Hospital Los Angeles, provide care for the largest number of transgendered youth in the U.S. and have enrolled 101 patients in a prospective observational study to determine the safety and efficacy of treatment that helps patients bring their bodies into closer alignment with their chosen gender.
Baseline characteristics of these individuals were published on July 21 in the Journal of Adolescent Health and include a significant finding: transgendered individuals have sex hormone levels consistent with the gender they were born with.
“We’ve now put to rest the residual belief that transgender experience is a result of a hormone imbalance,” says Olson. “It’s not.”
Weyl points, the 3D analogues of the structures that make graphene exceptional, were theoretically predicted in 1929. Today, an international team of Physicists from MIT and Zhejiang University, found them in photonic crystals, opening a new dimension in photonics.
