A process developed to increase efficiency and productivity in Japanese car factories has helped improve stroke treatment at Barnes-Jewish Hospital, report researchers at Washington University School of Medicine in St. Louis.
By applying the principles of Toyota's lean manufacturing process, doctors sharply reduced the average time between patient arrival and treatment, known as door-to-needle time, from 58 to 37 minutes.
It's fall football season, when fight songs and shouted play calls fill stadiums across the country. Another less rousing sound sometimes accompanies football games: the sharp crack of helmet-to-helmet collisions. Hard collisions can lead to player concussions, but the physics of how the impact of a helmet hit transfers to the brain are not well understood. A research team from the U.S. Naval Academy in Annapolis, Md., has created a simplified experimental model of the brain and skull inside a helmet during a helmet-to-helmet collision.
The whiskers of newborn rats twitch as they sleep, and that could open the door to new understandings about the intimate connections between brain and body. The discovery reinforces the notion that such involuntary movements are a vital contributor to the development of sensorimotor systems, say researchers who report their findings along with video of those whisker twitches on October 18 in Current Biology, a Cell Press publication.
AUSTIN, Texas – Individuals who have their first sexual experience later than average may have more satisfying romantic relationships in adulthood, according to a new study from The University of Texas at Austin.
The study by Paige Harden, assistant professor in the Department of Psychology and the Population Research Center, suggests that those who had a later first sexual experience were also less likely to be married and had fewer romantic partners in adulthood.
PULLMAN, Wash. - A Washington State University researcher has found that engaging elementary school students in science for as little as 10 hours a year can lead to improved test scores in math and language arts.
Samantha Gizerian, a clinical assistant professor in WSU's Department of Veterinary and Comparative Anatomy, Pharmacology and Physiology, saw improved test scores among fourth-grade students in South Los Angeles after students from the Charles R. Drew University of Medicine and Science gave 10 one-hour presentations on science.
MADISON — Decreased activity of a group of genes may explain why in young children the "fear center" of the anxious brain can't learn to distinguish real threats from the imaginary, according to a new University of Wisconsin study.
An Indiana University study that examined the effect of age and physical activity on lower leg muscle reflexes and coordination concluded that participation in physical activity was beneficial for lower leg muscle coordination across both sides of the body in both young and older study participants. Lower limb muscle communication is essential for everyday tasks, such as walking, balancing, and climbing stairs.
Dolphins sleep with only one half of their brains at a time, and according to new research published Oct. 17 in the open access journal PLOS ONE, this trait allows them to stay constantly alert for at least 15 days in a row. Brian Branstetter from the National Marine Mammal Foundation and colleagues found that dolphins can use echolocation with near-perfect accuracy continuously for up to 15 days, identifying targets and monitoring their environment.
Men and women with autism spectrum conditions (ASC) may show subtle but significant differences in the cognitive functions impacted by the condition, according to new research published Oct 17 by Meng-Chuan Lai and colleagues from the Autism Research Centre at the University of Cambridge, UK in the open access journal PLOS ONE.
Children with autism have difficulty identifying inappropriate social behavior, and even when successful, they are often unable to justify why the behavior seemed inappropriate. New brain imaging studies show that children with autism may recognize socially inappropriate behavior, but have difficulty using spoken language to explain why the behavior is considered inappropriate, according to research published Oct. 17 in the open access journal PLOS ONE by Elizabeth Carter from Carnegie Mellon University and colleagues.
Crows fed on prion-infected brains from mice can transmit these infectious agents in their feces and may play a role in the geographic spread of diseases caused by prions, such as chronic wasting disease or scrapie. The new research published Oct. 17 in the open access journal PLOS ONE by Kurt VerCauteren from the US Department of Agriculture (USDA) and other colleagues, shows that prions can pass through crows' digestive systems without being destroyed, and may be excreted intact after ingestion by the birds.
PHILADELPHIA - Changes in the ability to smell and taste can be caused by a simple cold or upper respiratory tract infection, but they may also be among the first signs of neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease. Now, new research from the Perelman School of Medicine at the University of Pennsylvania has revealed an association between an impaired sense of smell and myasthenia gravis (MG), a chronic autoimmune neuromuscular disease characterized by fluctuating fatigue and muscle weakness.
NEW BRUNSWICK, N.J. – A Rutgers study of recent New Jersey college and university graduates with disabilities has found that students attributed their academic success to a combination of possessing such strong personality traits as self-advocacy and perseverance, and their relationship with a faculty or staff mentor.
MINNEAPOLIS – Research shows that use of popular antidepressants is linked to an increased risk of some strokes caused by bleeding in the brain, but that the risk is low, according to a multi-study analysis published in the October 17, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Overturning decades of conventional wisdom, researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have found that moderately high indoor concentrations of carbon dioxide (CO2) can significantly impair people's decision-making performance. The results were unexpected and may have particular implications for schools and other spaces with high occupant density.
