Although reduced physical activity during the day is widely seen as a harbinger of mortality in older people, fragmentation of physical activity—spreading daily activity across more episodes of brief activity—may be an earlier indicator of mortality risk than total amount of daily activity, according to a new study from scientists at the Johns Hopkins Bloomberg […]
Researchers in the Academic Unit of Neurology at Trinity College Dublin have identified characteristic changes in the patterns of electrical brain wave activity in motor neurone disease (MND). This ground breaking observation will help to develop treatments for the disease that affects over 350 people in Ireland. Their findings, published in the recent issue of […]
An imbalance of functioning in attention-related brain systems may help forecast the course of teen depression, according to a study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, published by Elsevier. Proper coordination of frontoinsular brain networks help us regulate our attention between external goals and self-focused or emotional thinking. But abnormalities in the coordination […]
An international research team has developed a new method for determining cell types in a tissue sample. The scientists determined the link between the activity of genes in the same cell type and made a model capable of “recognizing” different cell types in mixed samples based on this relation. This approach works for all tissues, […]
(HealthDay)—Both low and high levels of physical activity (PA) are associated with reduced all-cause mortality, according to a study published online March 19 in the British Journal of Sports Medicine. Min Zhao, from Shandong University in Jinan, China, and colleagues examined data from the National Health Interview Surveys (1997 to 2008) linked to the National […]
It is never too late for physical Training According to a new study it is never to late to Sport or more activity and movement to begin with. Even in a sophisticated age, exercise can reduce unwanted weight and life expectancy increase. The positive effects on people, which only begin in the late age with […]
The tell-tale tremors of Parkinson’s disease emerge from abnormal activity in a brain region crucial for voluntary movement. Using a mouse model of the disease, researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) identified unusual patterns of brain activity that appear to underlie its signature symptoms. Parkinson’s disrupts the basal ganglia, […]
Requiring physical activity classes in college encourages sedentary students to become more active, while elective classes tend to draw those who are already motivated, new research from Oregon State University has found. “When there is no requirement but the courses are available as electives, the students who take the courses tend to be those who […]
Hangovers slow your brain down by lowering its electrical activity Hangovers DO slow your brain down by lowering its electrical activity, say scientists who recommend taking a day off and ‘avoiding big decisions’ after a heavy night Study finds alcohol hangovers hampers learning and reward processing in brain University of Victoria analysed 62 subjects – […]
New research highlights the extent to which epigenetic variation is influenced by both inherited and environmental factors. Epigenetic processes affect the expression or activity of genes without changing the underlying DNA sequence and are believed to be one mechanism by which the environment can interact with the genome. Now, an international group of researchers including […]
