More than a third of stroke patients don't get to the hospital by ambulance, even though that's the fastest way to get there, according to new research in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal.

A study in The Journal of General Physiology presents new methods to evaluate how astrocytes contribute to brain function, paving the way for future exploration of these important brain cells at unprecedented levels of detail.
WATERLOO, Ont. (Monday, April 29, 2013) – Researchers at the University of Waterloo have found that children hear more complex language from parents when they read a storybook with only pictures compared to a picture-vocabulary book. The findings appear in the latest issue of the journal First Language.
CAMBRIDGE, MA -- Suppose you hear someone say, "The man gave the ice cream the child." Does that sentence seem plausible? Or do you assume it is missing a word? Such as: "The man gave the ice cream to the child."
A new study by MIT researchers indicates that when we process language, we often make these kinds of mental edits. Moreover, it suggests that we seem to use specific strategies for making sense of confusing information — the "noise" interfering with the signal conveyed in language, as researchers think of it.
PITTSBURGH—This past weekend teams from the National Football League used statistics like height, weight and speed to draft the best college players, and in a few weeks, armchair enthusiasts will use similar measures to select players for their own fantasy football teams. Neuroscientists at Carnegie Mellon University are taking a similar approach to compile "dream teams" of neurons using a statistics-based method that can evaluate the fitness of individual neurons.
BLOOMINGTON, Ind. -- A team of American and Italian neuroscientists has identified a cellular change in the brain that accompanies obesity. The findings could explain the body's tendency to maintain undesirable weight levels, rather than an ideal weight, and identify possible targets for pharmacological efforts to address obesity.
Body dysmorphic disorder is a disabling but often misunderstood psychiatric condition in which people perceive themselves to be disfigured and ugly, even though they look normal to others. New research at UCLA shows that these individuals have abnormalities in the underlying connections in their brains.
When a mouse smells a cat, it instinctively avoids the feline or risks becoming dinner. How? A Northwestern University study involving olfactory receptors, which underlie the sense of smell, provides evidence that a single gene is necessary for the behavior.
University of Leicester-led research has shown that university students behave very differently when using social media as part of their academic learning.
Some students happily use social networking to share information about their course with their peers, in a similar way to how they might talk to friends on Facebook.
Others are much more targeted in their use of online tools – and will only log on to get the information they need, when they need it.
Learning disabilities affect up to 10 percent of children and co-occur at higher than expected rates
Up to 10 per cent of the population is affected by specific learning disabilities (SLDs), such as dyslexia, dyscalculia and autism, translating to two or three pupils in every classroom, a new study has found.
During fetal development of the mammalian brain, the cerebral cortex undergoes a marked expansion in surface area in some species, which is accommodated by folding of the tissue in species with most expanded neuron numbers and surface area. Researchers have now identified a key regulator of this crucial process.
Sand-dwelling and rock-dwelling cichlids living in East Africa's Lake Malawi share a nearly identical genome, but have very different personalities. The territorial rock-dwellers live in communities where social interactions are important, while the sand-dwellers are itinerant and less aggressive.
As scientists probe and parse the genetic bases of what makes a human a human (or one human different from another), and vigorously push for greater use of whole genome sequencing, they find themselves increasingly threatened by the unthinkable: Too much data to make full sense of.
Children who are exposed to negative parenting – including abuse, neglect but also overprotection – are more likely to experience childhood bullying by their peers, according to a meta-analysis of 70 studies of more than 200,000 children.
The research, led by the University of Warwick and published in the journal Child Abuse & Neglect, found the effects of poor parenting were stronger for children who are both a victim and perpetrator of bulling (bully-victims) than children who were solely victims.
MAYWOOD, Il. – A protein known to be a key player in the development of Parkinson's disease is able to enter and harm cells in the same way that viruses do, according to a Loyola University Chicago Stritch School of Medicine study.
