Berkeley — New technology developed at the University of California, Berkeley, is using wireless signals to provide real-time, non-invasive diagnoses of brain swelling or bleeding.

The device analyzes data from low energy, electromagnetic waves, similar to the kind used to transmit radio and mobile signals. The technology, described in the May 14 issue of the journal PLOS ONE, could potentially become a cost-effective tool for medical diagnostics and to triage injuries in areas where access to medical care, especially medical imaging, is limited.

All mammals sleep, as do birds and some insects. However, how this basic function is regulated by the brain remains unclear. According to a new study by researchers from the RIKEN Brain Science Institute, a brain region called the lateral habenula plays a central role in the regulation of REM sleep. In an article published today in the Journal of Neuroscience, the team shows that the lateral habenula maintains and regulates REM sleep in rats through regulation of the serotonin system.

Forget apples – lifting weights and doing cardio can also keep the doctors away, according a new study by researchers at the University of British Columbia and Vancouver Coastal Health Research Institute.

Having a hysterectomy with or without ovary removal in mid-life does not increase a woman's risk of cardiovascular disease compared to women who reach natural menopause, contrary to many previously reported studies, according to research published online today in the Journal of the American College of Cardiology.

The time may be fast approaching for researchers to take better advantage of the vast amount of valuable patient information available from U.S. electronic health records. Lian Duan, an NJIT computer scientist with an expertise in data mining, has done just that with the recent publication of "Adverse Drug Effect Detection," IEEE Journal of Biomedical and Health Informatics (March, 2013).

A Brazilian investigative team, collaborating with a Simon Fraser University researcher, is citing an urgent need for targeted interventions among young crack users in cities throughout Brazil, identified as the world's biggest crack market, and further research to better address the problem.

The song, "Get Happy," famously performed by Judy Garland, has encouraged people to improve their mood for decades. Recent research at the University of Missouri discovered that an individual can indeed successfully try to be happier, especially when cheery music aids the process. This research points to ways that people can actively improve their moods and corroborates earlier MU research.

Sporting events can bring a community together, such as when the Louisville Cardinals won the NCAA championship and University of Louisville campus was filled with camaraderie. They also can fuel bitter rivalries, such as the long-standing animosity between the St. Louis Cardinals and the Chicago Cubs. A University of Missouri study has found that testosterone levels during group competition are modulated depending on the relationships among the competitors and may be related to the formation of alliances in warfare.

New research at The University of Nottingham is calling for changes to a government scheme which engages community nurses in the prevention of child abuse and neglect in the home as part of a maternal and child health care programme.

The study, published online by the Journal of Public Health, has found that despite being set up to help reduce the numbers of child abuse cases, the £10 million Family Nurse Partnership will only be able to tackle around 10% of families involved in child maltreatment.

Scientists at Washington University School of Medicine in St. Louis have helped identify many of the biomarkers for Alzheimer's disease that could potentially predict which patients will develop the disorder later in life. Now, studying spinal fluid samples and health data from 201 research participants at the Charles F. and Joanne Knight Alzheimer's Disease Research Center, the researchers have shown the markers are accurate predictors of Alzheimer's years before symptoms develop.

Data from more than 180 research papers suggests fish oils could minimise the effects that junk food can have on the brain, a review by researchers at the University of Liverpool has shown.

The team at the University's Institute of Ageing and Chronic Disease reviewed research from around the world to see whether there was sufficient data available to suggest that omega-3s had a role to play in aiding weight loss.

A novel drug candidate, J147, is able to reverse memory deficits and improve several aspects of brain function in mice with advanced symptoms of Alzheimer's disease (AD), finds research in BioMed Central's open access journal Alzheimer's Research & Therapy.

Women whose breast cancer had been treated with chemotherapy demonstrated improved executive function, such as cognitive flexibility, verbal fluency and processing speed after using exercises developed by Lumosity, the leading online cognitive training program. The study also found significant improvement in self-reported measures of everyday executive function and observed some transfer to verbal memory. Researchers at Stanford University published the results in the peer-reviewed journal, Clinical Breast Cancer. Dr.

NEW YORK, May 14, 2013 – In a first-of-its-kind effort to illuminate the biochemical impact of trauma, researchers at NYU Langone Medical Center have discovered a connection between the quantity of cannabinoid receptors in the human brain, known as CB1 receptors, and post-traumatic stress disorder, the chronic, disabling condition that can plague trauma victims with flashbacks, nightmares and emotional instability.
