Because of the very low nitrate levels found in arctic tundra soil, scientists had assumed that plants in this biome do not use nitrate. But a new study co-authored by four Marine Biological Laboratory (MBL) Ecosystems Center scientists challenges this notion. The study has important implications for predicting which arctic plant species will dominate as the climate warms, as well as how much carbon tundra ecosystems can store.
Tropical Cyclone Marcus continues to parallel Western Australia and remain far from the coast, while weakening. NASA's Aqua satellite analyzed the storm in infrared light and saw a comma-shaped Marcus.
A cloud of gas 300,000 light-years long is arching around the Milky Way, shunted away from two dwarf galaxies orbiting our own. For decades, astronomers have wanted to know which of the two galaxies, the Large and Small Magellanic Clouds, is the source of the gas that has been expelled as the two galaxies gravitationally pull at one another. The answer will help astronomers understand how galaxies form and change over time.
Because there's currently no cure for dementia, it's important to know about risk factors that may lead to developing it. For example, researchers have learned that older adults with slower walking speeds seem to have a greater risk than those with faster walking speeds. Recently, researchers from the UK. teamed up to learn more about changes in walking speed, changes in the ability to think and make decisions, and dementia.
NUST MISIS scientists jointly with their colleagues from the Ecole de Technologie Superiore (Montreal, Canada) have experienced a new combination of alloy processing that produces solid and durable implants that are fully compatible with the human body. The research article is published in the Journal of Alloys and Compounds.
At the 47th Annual Meeting of the American Association for Dental Research (AADR), held in conjunction with the 42nd Annual Meeting of the Canadian Association for Dental Research (CADR), Brandon Michael Syme, University of Iowa College of Dentistry, Iowa City, presented a poster titled 'Opioid Prescribing Patterns of Oral and Maxillofacial Surgeons: A Nationwide Survey.' The AADR/CADR Annual Meeting is in Fort Lauderdale, Fla., USA from March 21-24, 2018.
At the 47th Annual Meeting of the American Association for Dental Research (AADR), held in conjunction with the 42nd Annual Meeting of the Canadian Association for Dental Research (CADR), Chad Lowell Wagner, University of Minnesota School of Dentistry, Minneapolis, presented a poster titled 'Effect of an Opioid Prescribing Protocol on Provider Prescribing Behavior.' The AADR/CADR Annual Meeting is in Fort Lauderdale, Fla., USA from March 21-24, 2018.
Researchers have recently focused on the role that dementia and other cognitive problems may play in falling, in hopes of discovering ways to manage and prevent falls. They published their study in the Journal of the American Geriatrics Society.
According to researchers, knee osteoarthritis affects some 55 percent of people over age 40 in Japan. A research team from the country recently published a study in the Journal of the American Geriatrics Society examining the effects of knee pain on depression since, until now, few studies have focused on how knee pain and impaired knee function relate to depression.
Results of a recent NRG Oncology study, NRGOncology/RTOG 0126, show that high-dose radiotherapy did not improve survival for men with intermediate-risk prostate cancer but did improve biochemical control and rates of distant metastases, when compared to standard radiotherapy. Men who received higher-dose radiotherapy underwent fewer salvage therapies to control tumors that had grown larger or had spread to another body site; however, they also experienced more side effects than did men on the standard radiotherapy treatment arm.
The number of missed hospital outpatient appointments increases following the clock change on March 25 2018.Patients are 5% more likely to miss an appointment in the week after the clocks go forward compared with the previous week. NHS figures show that there were 8 million missed appointments in 2016/17. Each hospital outpatient appointment costs £120 so missed appointments represent a significant financial issue for the NHS and have a negative impact on patient care.
At the OSA Biophotonics Congress: Biomedical Optics meeting, held 3-6 April in Hollywood, Florida, USA, researchers from Milan, Italy, will report an advance in instrument development that increases the sensitivity of OM by as much as 1000-fold.
NASA satellite imagery showed that Tropical Cyclone Nora developed an eye as it strengthened into a hurricane north of Australia. NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of the storm, formerly named Tropical Cyclone 16P.
Early adulthood is particularly critical for putting on weight. According to a recent study conducted at the University of Helsinki, common factors among young women and men who succeeded in managing their weight in the long term included eating regularly rather than dieting.
n a new study, published in the Journal of the American Geriatrics Society, researchers looked at a way to help older adults taper off and stop using sedatives. This was based on an earlier study that suggested giving older adults an educational brochure outlining the problems that sedatives pose and instructions for safely taking themselves off the medication.
Scientists have identified a new species of reptile from prehistoric Connecticut and, boy, does it have a mouth on it. Named Colobops noviportensis, the creature lived 200 million years ago and had exceptionally large jaw muscles -- setting it apart from other reptiles at the time. Even compared to the wide diversity of reptile species today, Colobops noviportensis had quite the bite.
Obesity and severe obesity continued to grow among adults in the United States between 2007-2008 and 2015-2016 but there were no significant overall changes among youth.
Swansea University Egyptology lecturer Dr Ken Griffin has found a depiction of one of the most famous pharaoh's in history Hatshepsut (one of only a handful of female pharaohs) on an object in the Egypt Centre stores, which had been chosen for an object handling session.
Research led by the University of Luxembourg investigated the manufacturing process of solar cells. The researchers proved that assumptions on chemical processes that were commonplace among researchers and producers for the past 20 years are, in fact, inaccurate. The physicists published their findings in the renowned scientific journal Nature Communications.
A preclinical study in rats has shown that there might be value in using a non-psychoactive and non-addictive ingredient of the Cannabis sativa plant to reduce the risk of relapse among recovering drug and alcohol addicts. The study's findings inform the ongoing debate about the possible medical benefits of non-psychoactive cannabinoids. So says Friedbert Weiss, leader of an investigative team at the Scripps Research Institute in La Jolla, California, in Neuropsychopharmacology published by Springer Nature.
