Back in 2010, the ideas behind a squid's sticky tendrils and Spiderman's super-strong webbing were combined to create a prototype for the first remote device able to stop vehicles in their tracks: the Safe, Quick, Undercarriage Immobilization Device (SQUID). At the push of a button, spiked arms shot out and entangled in a car's axles—bringing a racing vehicle to a screeching halt.*

Reducing fear and stress following a traumatic event could be as simple as providing a protein synthesis blocker to the brain, report a team of researchers from McLean Hospital, Harvard Medical School, McGill University, and Massachusetts General Hospital in a paper published in the March 4 issue of Proceedings of the National Academy of Sciences.
A marathon runner approaches the finishing line, but suddenly the sweaty athlete collapses to the ground. Everyone probably assumes that this is because he has expended all energy in his muscles. What few people know is that it might also be a braking mechanism in the brain which swings into effect and makes us too tired to continue. What may be occurring is what is referred to as 'central fatigue'.
A team of scientists and clinicians at UC San Francisco has discovered how to detect abnormal brain rhythms associated with Parkinson's by implanting electrodes within the brains of people with the disease.
The work may lead to developing the next generation of brain stimulation devices to alleviate symptoms for people with the disease.
PHILADELPHIA — The mammalian placenta is more than just a filter through which nutrition and oxygen are passed from a mother to her unborn child. According to a new study by a research group from the University of Pennsylvania School of Veterinary Medicine, if a mother is exposed to stress during pregnancy, her placenta translates that experience to her fetus by altering levels of a protein that affects the developing brains of male and female offspring differently.
The brain adds new cells during puberty to help navigate the complex social world of adulthood, two Michigan State University neuroscientists report in the current issue of the Proceedings of the National Academy of Sciences.
Scientists used to think the brain cells you're born with are all you get. After studies revealed the birth of new brain cells in adults, conventional wisdom held that such growth was limited to two brain regions associated with memory and smell.
Does advertising influence society, or is it merely a reflection of society's pre-existing norms? Where male attitudes are concerned, a new study implicates magazine advertisements specifically aimed at men as helping to reinforce a certain set of views on masculinity termed "hyper-masculinity." The article by Megan Vokey, a Ph.D. candidate from the University of Manitoba, and colleagues is published in Springer's journal Sex Roles.
(Baltimore, MD) – New findings published in Pediatrics (Epub ahead of print) by the Kennedy Krieger Institute's Center for Autism and Related Disorders reveal that 70 percent of children with autism spectrum disorders (ASD) who have a history of severe language delay, achieved phrase or fluent speech by age eight. This suggests that more children presenting with ASD and severe language delay at age four can be expected to make notable language gains than was previously thought.
BOSTON, Mass, March 4, 2013—The first large, population-based study to follow children with attention-deficit hyperactivity disorder (ADHD) into adulthood shows that ADHD often doesn't "go away," and that children with ADHD are more likely to have other psychiatric disorders as adults. Although numbers were small, they also appear more likely to commit suicide and are often incarcerated as adults.
The interplay between an infection during pregnancy and stress in puberty plays a key role in the development of schizophrenia, as behaviourists from ETH Zurich demonstrate in a mouse model. However, there is no need to panic.
Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich identify a novel signal transduction pathway, which activates the parkin gene and prevents stress-induced neuronal cell death.
Images have been transformed into pixels and projected onto a headset to help the visually impaired in everyday tasks such as navigation, route-planning and object finding.
Developed using a video camera and mathematical algorithm, the researchers from the University of Southern California hope the pixels can provide more information and enhance the vision of patients already fitted with retinal implants.
West Orange, NJ. February 28, 2013. The March 2013 issue of Archives of Physical Medicine & Rehabilitation, the medical journal of the American Congress of Rehabilitation Medicine, features an article by Kessler researchers Pasquale Frisina, PhD, Ann Kutlik, BA, and A.M. Barrett, MD.
GAINESVILLE, Fla. — Researchers at the University of Florida and The Johns Hopkins University have developed a line of genetically altered mice that model the earliest stages of Alzheimer's disease. This model may help scientists identify new therapies to provide relief to patients who are beginning to experience symptoms.
The researchers report their findings in the current issue of The Journal of Neuroscience.
DARIEN, IL – A new study found that adult sleepwalking is a potentially serious condition that may induce violent behaviors and affect health-related quality of life.
