Alexandria, VA, USA - 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), featured a symposium titled "The Novel Insights of Proteoglycans in Mineralized Tissues." The AADR/CADR Annual Meeting is in Fort Lauderdale, Fla., USA from March 21-24, 2018.
Researchers have developed a stretchable, flexible patch that could make it easier to perform ultrasound imaging on odd-shaped structures, such as engine parts, turbines, reactor pipe elbows and railroad tracks--objects that are difficult to examine using conventional ultrasound equipment.
The ultrasound patch is a versatile and more convenient tool to inspect machine and building parts for defects and damage deep below the surface. A team of researchers led by engineers at the University of California San Diego published the study in the Mar. 23 issue of Science Advances.
BOZEMAN -- Researchers at Montana State University in Bozeman have published a study showing how access to high-quality fruits and vegetables - or lack thereof - strongly influences whether healthy foods make it to a person's breakfast, lunch or dinner plate.
"Fruit and vegetable desirability is lower in more rural built food environments of Montana, USA using the Produce Desirability(ProDes) Tool" was published Jan. 23 in the journal Food Security.
The brain is a complex network containing billions of neurons, where each of these neurons communicates simultaneously with thousands of other via their synapses (links). However, the neuron actually collects its many synaptic incoming signals through several extremely long ramified "arms" only, called dendritic trees.
In 1949 Donald Hebb's pioneering work suggested that learning occurs in the brain by modifying the strength of the synapses, whereas neurons function as the computational elements in the brain. This has remained the common assumption until today.
A novel lens offers scientists the sharpest X-ray images yet from the nano world. The device is made from alternating layers of tungsten carbide and silicon carbide and can focus hard X-rays into a spot of less than ten nanometers in diameter as a team lead by Saša Bajt from the German research center Deutsches Elektronen-Synchrotron DESY report in Light: Science and Applications, a journal of the Nature Publishing Group.
Researchers at Houston Methodist used computer modeling to find an existing investigational drug compound for leukemia patients to treat triple negative breast cancer once it spreads to the brain.
The Houston Methodist researchers culled through thousands of existing drugs to see if they could identify a compound that would prevent cancer cells from spreading, or metastasizing. They discovered edelfosine, which has been FDA-approved as an investigational leukemia treatment, and has also been used in clinical research for primary brain tumors.
These days, Americans shop for nearly everything online--including marijuana. That's the conclusion of a new study published today in the American Journal of Preventive Medicine led by San Diego State University Graduate School of Public Health associate research professor John W. Ayers. Millions are searching for and finding online marijuana retailers across the country, the researchers find.
Researchers at Chalmers University of Technology have shown that between 87 and 98 percent of ships comply with the tougher regulations for sulphur emissions that were introduced in northern Europe in 2015. The lowest levels of compliance were observed in the western part of the English Channel and in the middle of the Baltic Sea.
Nearly a third of all antibiotics prescribed for hospitalized children globally were intended to prevent potential infections rather than to treat disease, according to the results of a worldwide survey published in the Journal of the Pediatric Infectious Diseases Society. A large proportion of these preventive, or prophylactic, prescriptions also were for broad-spectrum antibiotics or combinations of antibiotics, or were for prolonged periods, which can hasten the development of antibiotic-resistant bacteria and drug-resistant infections.
Alexandria, VA, USA - 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), featured a symposium sponsored by the American Dental Association (ADA) titled "Transforming Oral Health Through Science and Evidence-based Practice." The AADR/CADR Annual Meeting is in Fort Lauderdale, Fla., USA from March 21-24, 2018.
The convection-allowing ensemble forecasting has significant research and application value, and the initial perturbation generation method plays an important role in the improvement of its accuracy. Recently, a research group led by Chaohui Chen from National University of Defense Technology proposed a new method to generate initial perturbation with full consideration of the strong locality of a convective weather system. The experimental results confirm that it can improve the effect of convection-allowing ensemble forecasting.
Understanding the factors that affect a bird species' nesting success can be crucial for planning effective conservation efforts. However, many studies of nesting birds last only a few years--and that means they can miss the effects of long-term variation and rare events. A new study from The Auk: Ornithological Advances demonstrates this with nearly four decades of data from Song Sparrows in British Columbia.
The race for quantum computing is on: Industry giants, such as Google, IBM, and Microsoft, and leading international research centers and universities are involved in the global effort to build a quantum computer. It is not known yet when this new technology can become a reality, but the world is getting ready. The greatest expectation about the quantum computer is that it could break the security of all classical data transfer networks.
Prolonged sitting time and low physical activity levels were linked with the development of lower urinary tract symptoms (LUTS) in a BJU International study of 69,795 middle-aged Korean men.
A team led by researchers at the Kangbuk Samsung Hospital, in South Korea, found that the incidence rate of LUTS--which relate to urine storage and/or voiding disturbances--was 39 per 1000 person-years. (A person-year is the number of years of follow-up multiplied by the number of people in the study.)
A new Journal of Internal Medicine article proposes that artificial intelligence tools, such as machine learning algorithms, have the potential for building predictive models for the diagnosis and treatment of diseases linked to imbalances in gut microbial communities, or microbiota.
