CORVALLIS, Ore. – A proven approach to slow the aging process is dietary restriction, but new research in the Linus Pauling Institute at Oregon State University helps explain the action of a drug that appears to mimic that process – rapamycin. Rapamycin, an antibiotic and immunosuppressant approved for use about 15 years ago, has drawn extensive interest for its apparent ability – at least in laboratory animal tests – to emulate the ability of dietary restriction in helping animals to live both longer and healthier. However, this medication has some drawbacks, including ...

Many have assumed that warmer winters as a result of climate change would increase the growth of trees and shrubs because the growing season would be longer. But shrubs achieve less yearly growth when cold winter temperatures are interrupted by temperatures warm enough to trigger growth. "When winter temperatures fluctuate between being cold and warm enough for growth, plants deplete their resources trying to photosynthesize and end the winter with fewer reserves than they initially had. In the summer they have to play catch up," said Melanie Harsch, a University of Washington ...

Boston, MA – Primary care providers who engaged in an online game to solve clinical cases about hypertension management improved blood pressure control of their patients in a shorter amount of time compared to non-gamers, according to a new study by researchers at Brigham and Women's Hospital (BWH) and the Veterans Affairs Boston Healthcare System. The study was published May 20, 2014 in Circulation: Cardiovascular Quality and Outcomes. "This study is the first to show that an online educational game among medical professionals can improve the health measures of their ...

WHAT: Clinicians treating patients suffering from Middle East respiratory syndrome (MERS) currently have no drugs specifically targeted to the MERS coronavirus (MERS-CoV), a virus first detected in humans in 2012 that has since caused 614 laboratory-confirmed infections, including 181 that were fatal, according to the World Health Organization. The case count escalated sharply in the spring of this year, and the first cases in the United States were announced in early May. To address the urgent need for therapies, researchers supported by the National Institutes of Health ...

ANN ARBOR—The Detroit Lions' new model of philanthropy and community engagement may prove to be a touchdown for the city of Detroit. A new case study of corporate social responsibility in sport by University of Michigan researchers uses the Lions as an exemplar of a professional sports team reinventing its charitable giving and community relations approach in hopes of making a bigger impact on the community. In 2012, the Lions created the "Living in the City" campaign—a new model of corporate philanthropy that emphasizes deeper relationships with a small core group ...

LOUISVILLE, Ky. – An aging population poses challenges for governments around the globe as nations grapple with how to satisfy the physical, social and economic needs of older adults. About 126 million adults 65 years and older live in China - the country with the largest population of senior citizens, while 40 million adults 65 years and older live in the United States. In an article published today in Journal of Transcultural Nursing, University of Louisville School of Nursing assistant professor Valerie Lander McCarthy, PhD, RN; Ji Hong, MSN, a visiting scholar from ...

Can plants and animals evolve to keep pace with climate change? A study published May 19 in the journal Proceedings of the National Academy of Sciences shows that for at least one widely-studied plant, the European climate is changing fast enough that strains from Southern Europe already grow better in the north than established local varieties. Small and fast-growing, Arabidopsis thaliana is widely used as the "lab mouse" of plant biology. The plant grows in Europe from Spain to Scandinavia and because Arabidopsis is so well-studied, there is a reference collection of ...

(Santa Barbara, Calif.) — As the largest purchaser of wholesale produce in Santa Barbara County, UC Santa Barbara's residential dining services provided the perfect avenue for a pilot project incorporating local pesticide-free or certified organic produce into an institutional setting. The idea was conceived almost 10 years ago, when a group of students approached environmental studies professor David Cleveland about becoming a faculty adviser for student-led sustainable living classes. The group wanted to explore how to bring more local organic food in the dining halls. ...

BERKELEY — California's winter tule fog -- hated by drivers, but needed by fruit and nut trees -- has declined dramatically over the past three decades, raising a red flag for the state's multibillion dollar agricultural industry, according to researchers at the University of California, Berkeley. Crops such as almonds, pistachios, cherries, apricots and peaches go through a necessary winter dormant period brought on and maintained by colder temperatures. Tule fog, a thick ground fog that descends upon the state's Central Valley between late fall and early spring, helps ...

A quantum particle can search for an item in an unsorted "database" by jumping from one item to another in superposition, and it does so faster than a classical computer ever could. This assertion assumes, however, that the particle can directly hop from any item to any other. Any restriction on which items the particle can directly hop to could slow down the search. "Intuition says that a symmetric database allows the particle to hop freely enough to retain the quantum speedup, but our research has shown this intuition to be false," says Tom Wong, a physicist at ...

Nearly half of all adults in the United States suffer from the gum disease periodontitis, and 8.5 percent have a severe form that can raise the risk of heart disease, diabetes, arthritis and pregnancy complications. University of Pennsylvania researchers have been searching for ways to prevent, half and reverse periodontitis. In a report published in the Journal of Immunology, they describe a promising new target: a component of the immune system called complement. Treating monkeys with a complement inhibitor successfully prevented the inflammation and bone loss that ...

Most Americans eat a diet that consists of little to no protein for breakfast, a bit of protein at lunch and an overabundance of protein at dinner. As long as they get their recommended dietary allowance of about 60 grams, it's all good, right? Not according to new research from a team of scientists led by muscle metabolism expert Doug Paddon-Jones of the University of Texas Medical Branch at Galveston. This research shows that the typical cereal or carbohydrate-dominated breakfast, a sandwich or salad at lunch and overly large serving of meat/protein for dinner may not ...

CHAMPAIGN, Ill. — Researchers have developed a new cognitive test that can better determine whether memory impairments are due to very mild Alzheimer's disease or the normal aging process. Their study appears in the journal Neuropsychologia. The Alzheimer's Association estimates that the number of Americans living with Alzheimer's disease will increase from 5 million in 2014 to as many as 16 million by 2050. Memory impairments and other early symptoms of Alzheimer's are often difficult to differentiate from the effects of normal aging, making it hard for doctors to ...

COLUMBIA, Mo. – Nearly 2 million children in the United States have experienced a parent's military deployment. Previous research has shown that these children may be at increased risk for emotional, behavioral and relationship difficulties, yet little is known about how best to address military children's specialized needs. Now, an MU researcher says school-based interventions could benefit children whose parents have deployed. David Albright, an assistant professor at the MU School of Social Work, says military children are an overlooked population in need ...

Resistance to antibiotics has been steadily rising, posing a threat to public health. Now, a method from Mohammad Seyedsayamdost, an assistant professor of chemistry at Princeton University, may open the door to the discovery of a host of potential drug candidates. The vast majority of anti-infectives on the market today are bacterial natural products, made by biosynthetic gene clusters. Genome sequencing of bacteria has revealed that these active gene clusters are outnumbered approximately ten times by so-called silent gene clusters. "Turning these clusters on would ...

This news release is available in German. Music can be soothing or stirring, it can make us dance or make us sad. Blood pressure, heartbeat, respiration and even body temperature – music affects the body in a variety of ways. It triggers especially powerful physical reactions in pregnant women. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig have discovered that pregnant women compared to their non-pregnant counterparts rate music as more intensely pleasant and unpleasant, associated with greater changes in blood pressure. Music ...

South and North side of the fire is contained. The terrain for this fire is steep with scattered boulders making firefighting more difficult. The entire fire is currently 44% contained and full containment is expected by Friday, May 23, according to Inciweb.org. The National Weather Service has forecast maximum temperatures ...

Boosting a key immune process called autophagy with interferon gamma (IFN-γ) could help clear a lethal bacterial infection in cystic fibrosis, a new study suggests. The work, led by a team in The Research Institute at Nationwide Children's Hospital and published in PLoS One in May, offers new information about immune function in patients with the disease. Cystic fibrosis, CF for short, is caused by a malfunction in the CFTR gene, which is responsible for transporting chloride and water across cell membranes. In people with the disease, cells that line the passageways ...

A recent study into the biomechanics of the necks of ants – a common insect that can amazingly lift objects many times heavier than its own body – might unlock one of nature's little mysteries and, quite possibly, open the door to advancements in robotic engineering. A small group of engineers at The Ohio State University combined laboratory testing and computational modeling conducted at the Ohio Supercomputer Center to determine the relationship between the mechanical function, structural design and material properties of the Allegheny mound ant (Formica exsectoides). ...

WASHINGTON D.C., May 20, 2014 -- The long life of lithium ion batteries makes them the rechargeable of choice for everything from implantable medical devices to wearable consumer electronics. But lithium ion batteries rely on liquid chemistries involving lithium salts dissolved in organic solvents, creating flame risks that would be avoided if the cells were completely solid-state. Now a team of researchers at Tohoku University in Japan has created a new type of lithium ion conductor for future batteries that could be the basis for a whole new generation of solid-state ...

Website privacy policies are almost obligatory for many online services, but for anyone who reads these often unwieldy documents, trust in the provider is more commonly reduced than gained, according to US researchers. Almost every commercial website, social network, search engine and banking site has a privacy policy. Indeed, these and countless other sites that scrape personal information via forms, logins and tracking cookies are obliged by law in some parts of the world to post a document online giving details of how they protect any personal data you give the site ...

New Rochelle, NY, May 20, 2014—Studies have identified mobile phones and related devices as sources of metal sensitization and potential causes of allergic contact dermatitis (ACD). Despite efforts to control allergen release in phones, many phones on the market release levels of metals, such as nickel and chromium, which are sufficient to induce ACD, according to an article in Pediatric Allergy, Immunology, and Pulmonology, a peer-reviewed journal published by Mary Ann Liebert, Inc., publishers. The article is available free on the Pediatric Allergy, Immunology, and Pulmonology ...

COLUMBUS, Ohio— Scientists delivered a mostly negative forecast for how climate change will affect Ohioans during the next year or so, and well beyond. Researchers report that the projected increase in precipitation and the associated runoff will likely lead to a larger-than-average bloom of harmful blue-green algae in Lake Erie this summer. In addition, the development of an El Niño over the Pacific later this year may result in a very dry 2015 in Ohio. But Ohio may fare better than its neighbors in one respect: While drought and high temperatures are expected to shrink ...

Researchers at the National Institutes of Health have uncovered a molecule in an animal model that acts as a key player in establishing the organization of the auditory system. The molecule, a protein known as Bmp7, is produced during embryonic development and acts to help sensory cells find their ultimate position on the tonotopic map, which is the fundamental principle of organization in the auditory system. The tonotopic map groups sensory cells by the sound frequencies that stimulate them. The study is the first to identify one of the molecular mechanisms that determines ...

This news release is available in French. One company's trash can be another's treasure. Take Marmite. Made from a by-product of commercial beer production, the yeast-based spread has topped toast throughout the Commonwealth for decades. By recuperating the waste product from one company, another was able to thrive. Environmental concerns are at the forefront of government policy, so the time is right for companies worldwide to adopt this type of resource exchange, known as industrial symbiosis (IS). A new study by Concordia University researcher Raymond Paquin ...
