More men than women develop Parkinson’s disease and new work presented at the Federation of European Neuroscience Societies says that it is do to sex differences in how brain cells change. Parkinson’s disease affects about 9 million people and becomes increasingly prevalent with age.
HOUSTON - (June 27, 2016) - Infertility affects about 15 percent of couples around the world. A couple's fertility depends on both the female's and male's ability to reproduce, which relies on thousands of genes working properly. In the male mouse, more than 1,000 genes are predominantly expressed in the testis, but their particular functions in reproduction are still a mystery. In a report published today in the Proceedings of the National Academy of Sciences, researchers from Baylor College of Medicine, Osaka University, University of Oulu and the Wellcome Trust Sanger Institute have discovered that 54 of the mouse testis-enriched genes, that also are expressed in humans, are not necessary for male fertility.
(NEW YORK June 27, 2016) The 2009 swine H1N1 flu pandemic -- responsible for more than 17,000 deaths worldwide -- originated in pigs from a very small region in central Mexico, a research team headed by investigators at the Icahn School of Medicine at Mount Sinai is reporting.
The scientists say their findings, published in the journal eLife, represent the first time that the origin of an influenza pandemic virus has been determined in such detail.
PULLMAN, Wash. - Washington State University researchers have developed a new software tool that will improve scientists' ability to identify and understand bacterial strains and accelerate vaccine development.
RepeatAnalyzer is able to track, manage, analyze and catalogue the short, repeating sequences of bacterial DNA.
The researchers used the software to characterize Anaplasma marginale, a tick-borne bacteria that affects cattle, and published their work in the journal BMC Genomics. The research team includes computer science student Helen Catanese; Kelly Brayton, Department of Veterinary Microbiology and Pathology; and Assefaw Gebremedhin, School of Electrical Engineering and Computer Science.
Since June 23, 2016 over two dozen people have been reported killed and hundreds of homes have been destroyed by flooding in West Virginia. Using satellite data, NASA calculated the heavy rainfall that occurred over the state.
The governor of West Virginia declared a federal disaster after the worst flooding in a century. The prevalence of rough terrain in West Virginia has amplified the effects of flooding rainfall. The National Weather Service predicted that thunderstorms were going to fall in the area again today. More flash flooding with streams again coming out of their banks has been predicted.
COLUMBUS, OH - In the northern hemisphere, peak ultraviolet radiation exposure is predicted to occur between 2010 and 2020. Decreases in ozone lead to increased exposure to wavelengths in the ultraviolet range, and ultraviolet radiation in turn affects plants' ability to effectively use photosynthesis for growth and development. Scientists say large land areas could be affected by UV-B exposure on turfgrasses that are typically cut high, such as those grasses used for residential lawns, so identifying grasses that can grow in evaluated UV-B conditions is crucial.
If asked to list problems that bad gut bacteria can cause, most would likely name digestive issues: constipation, excessive gas, or diarrhea.
Researchers are now saying bad gut bacteria - or an insufficient amount of good bacteria - may have a direct link to multiple sclerosis as well.
"Every human carries trillions of bacteria in their gut (gut microbiome) and recent advances in research indicate that these tiny passengers play an important role in our overall health maintenance," says Ashutosh Mangalam, PhD, assistant professor of pathology at the University of Iowa Carver College of Medicine.
INDIANAPOLIS - Many testicular cancer survivors experience hearing loss after cisplatin-based chemotherapy, according to researchers at Indiana University.
The researchers, led by Lois B. Travis, M.D., Sc.D., the Lawrence D. Einhorn Professor of Cancer Research at the IU School of Medicine and a researcher at the Indiana University Melvin and Bren Simon Cancer Center, studied for the first time the cumulative effects of cisplatin-based chemotherapy on hearing levels in testicular cancer survivors through comprehensive audiometry measurements. They found that increasing doses of cisplatin were associated with increased hearing loss at most of the tested frequencies, involving 4, 6, 8, 10, and 12 kHz.
Researchers at Hospital for Special Surgery (HSS) have uncovered a potential genetic trigger of systemic autoimmune disease. The study, the culmination of more than 10 years of research and published online in the journal Arthritis & Rheumatology in June, discovered virus-like elements within the human genome linked to the development of two autoimmune diseases: lupus and Sjogren's syndrome.
An autoimmune disorder occurs when the body's immune system malfunctions. Instead of protecting the body, it attacks and destroys healthy organs. More than 80 types of autoimmune disorders, including rheumatoid arthritis, lupus and Sjogren's syndrome, affect up to 22 million people in the United States, according to the National Institutes of Health.
A team of New York-based researchers has compared the effects of two disease-causing mutations, potentially explaining why patients with the rare genetic disorder keratitis-ichthyosis-deafness (KID) syndrome can experience different sets of symptoms. The study, "Syndromic deafness mutations at Asn 14 differentially alter open stability of Cx26 hemichannels," will be published online June 27, 2016 in The Journal of General Physiology.
Bumble bees have discriminating palettes when it comes to their pollen meals, according to researchers at Penn State. The researchers found that bumble bees can detect the nutritional quality of pollen, and that this ability helps them selectively forage among plant species to optimize their diets.
"Populations of many bee species are in decline across the world, and poor nutrition is thought to be a major factor causing these declines," said Christina Grozinger, director of the Center for Pollinator Research, Penn State. "Our studies can help identify plant species and stocks that provide high-quality nutrition for bumble bees and potentially other bee species, which will help in the development of pollinator-friendly gardens and planting strips."
The era of quantum computers is one step closer as a result of research published in the current issue of the journal Science. The research team has devised and demonstrated a new way to pack a lot more quantum computing power into a much smaller space and with much greater control than ever before. The research advance, using a 3-dimensional array of atoms in quantum states called quantum bits -- or qubits -- was made by David S. Weiss, professor of physics at Penn State University, and three students on his lab team.
An international research collaboration led by UCL scientists has developed ways to improve the quality and accuracy of information harvested from epigenome sequencing datasets in two new research papers published jointly in Nature Biotechnology and Nature Communications today. According to the studies, epigenome sequencing technologies can allow for more comprehensive analysis of cancers - a key component in the development of targeted approaches to combat cancer.
