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.
Our visual system is constantly bombarded with complex optical information. The input information is often insufficient or ambiguous, leading to potentially conflicting interpretations about the structure of the physical world. The human brain has amazing computational powers to resolve these ambiguities and generate a coherent perception almost instantly. As a way to understand how our brain works, scientists have been fascinated about how the human brain achieves this goal.
DNA tests have confirmed that one of the three southern rockhopper penguin chicks born at Osaka Aquarium Kaiyukan between June 4 and 6 was conceived through artificial insemination. This is the result of a project led by Kaiyukan with the collaboration of Associate Professor KUSUNOKI Hiroshi (Kobe University Graduate School of Agricultural Science). It is the world's first successful case of a southern rockhopper penguin being conceived through artificial insemination.
Southern rockhopper penguins are a species of birds approximately 50cm in height which inhabit southern islands near Antarctica such as the Falkland Islands. They are on the red list of the International Union for Conservation of Nature as a threatened species.
The media often imply that the goal of the hunt for extrasolar planets is to find a rocky planet about the size of Earth orbiting a star like the sun at a distance that would allow liquid water to persist on its surface. In other words, the goal is to find Earth 2.0.
But there are reasons to be interested in the other worlds even if they couldn't possibly harbor life. The hot, rocky planets, for example, offer rare and precious clues to the character and evolution of the early Earth.
The Kepler satellite has detected more than 100 hot, rocky planets orbiting close to their stars. If these planets formed from interstellar clouds with Earth-like abundances of volatile elements, like hydrogen, water and carbon dioxide, these planets might have steam atmospheres.
Plasmodium vivax (P. vivax) parasites, which cause a debilitating form of malaria, are yielding their secrets to an international team of researchers funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. In the largest such effort to date, the team determined complete genomes of nearly 200 P. vivax strains that recently infected people in eight countries. Comparative analysis showed the parasites clustered into four genetically distinct populations that provide insights into the movement of P. vivax over time and suggest how it is still adapting to regional variations in both the mosquitoes that transmit it and the humans it infects.
A first-of-its-kind survey has confirmed what some water polo players - especially goalies - have long suspected: Concussions seem to be prevalent in the sport. At least in surveys.
More than a third of water polo participants reported sustaining a concussion either during games or in practice, according to a poll conducted by University of California, Irvine.
Common statistical methods used to analyse brain activity through images taken with MRI scanners cannot be trusted, as shown by Anders Eklund and Hans Knutsson of Linköping University, and Thomas Nichols of the University of Warwick, in the highly-ranked journal PNAS.
LiU Reader Eklund who works at the Department of Computer and Information Science and the Department of Biomedical Engineering, respectively, tested the analysis methods by using them on known, reliable data. The methods showed false activity in the brain in 60 percent of the cases. A reasonable figure is five percent.
As soon as social considerations also play a part in economic decisions, our brain seems to switch to a different processing mode. At least this is indicated by the results of a current study that was conducted at the University of Bonn. In it the participants were able to purchase pieces of music but could themselves set the price to be paid. During the process, the researchers recorded the brain activity of the participants. The work will soon appear in the prestigious journal Frontiers in Psychology but can already be called up online.
89% of school children consuming sports drinks with 68% drinking them regularly (1-7 times per week)
Sports drinks purchased by children in local shops at value prices
A high proportion of 12-14 year olds are regularly consuming sports drinks socially, increasing their risk of obesity and tooth erosion, concludes a Cardiff University School of Dentistry survey.
Published today in the British Dental Journal, the survey looked at 160 children in four schools across South Wales and concluded that children are attracted to sports drinks because of their sweet taste, low price, and availability, with most parents and children not aware that sports drinks are not intended for consumption by children.
It is quite surprising that, while food is so central to our lives, neuroscience has devoted limited energy to understanding how it is represented in our brain. Aware of this shortcoming, Raffaella Rumiati, professor at SISSA where she leads the INSuLa laboratory, and Francesco Foroni, SISSA research scientist, reviewed the research published to date on the topic. One of the novelties of their review is that it also considered papers dealing with brain-damaged patients. Very few studies have in fact investigated this aspect, so Rumiati and Foroni looked for those using food items as stimuli and then filtered the results through the lens of the most widely accepted theories of semantic categorization.
BOSTON (Embargoed until 11 AM EDT, June 27, 2016)--Blood levels of seafood and plant-based omega-3 fatty acids are moderately associated with a lower risk of dying from heart attacks, according to a new epidemiological study, published today in JAMA Internal Medicine, led by Liana C. Del Gobbo, Ph.D., a postdoctoral research fellow in the division of cardiovascular medicine at Stanford University School of Medicine and senior author Dariush Mozaffarian, M.D., Dr.P.H., dean of the Friedman School of Nutrition Science and Policy at Tufts University in Boston.
COLUMBUS, Ohio--It's one of life's little annoyances: that last bit of shampoo that won't quite pour out of the bottle. Or the last bit of hand soap, or dish soap, or laundry detergent.
Now researchers at The Ohio State University have found a way to create the perfect texture inside plastic bottles to let soap products flow freely. They describe the patent-pending technology in a paper to appear in the journal Philosophical Transactions of the Royal Society on June 27.
ANN ARBOR, Mich. -- Even if you have what you might think of as good health insurance, your next hospital stay could cost you more than $1,000 out of your own pocket.
And that amount has gone up sharply in recent years - a rise of more than 37 percent just for straightforward hospital stays for common conditions.
Those striking statistics come from the first published analysis of actual out-of-pocket spending by people with private health insurance, most of it provided by employers. It's appearing today in the JAMA Internal Medicine, and being presented at the AcademyHealth Annual Research Meeting in Boston.
