Brain

Biomedical scientists from the University of Central Florida and Louisiana State University have identified a way to block a "cell death signal" that they believe triggers brain damage during strokes.

Strokes, also known as cerebral ischemia, are caused by inadequate blood flow to the brain and are the third-leading cause of death in the United States.

Elliot Jacques coined the term "mid-life crisis" 40 years ago, when the average lifespan was 70 and "mid-life" came at age 35. Individuals could expect their quality of life to decline from that point forward, Jacques argued, so some extreme reactions to encroaching mortality were to be expected, such as having extra-marital affairs and buying a Corvette.

Handheld devices such as personal digital assistants (PDAs) and the iPod Touch are prevalent among doctors. However a recent study shows that these devices may be particularly useful for emergency radiologists, who in the near future, may be able to use them for teleconsultation and emergency procedures, according to a study published in the February issue of the American Journal of Roentgenology.

DURHAM, N.C. – Years before adults develop schizophrenia, there is a pattern of cognitive difficulties they experience as children, including problems with verbal reasoning, working memory, attention and processing speed.

Drawing on a long-term study of more than 1,000 New Zealanders born from 1972 to 1973, a team led by Duke researchers has found a consistent pattern of developmental difficulties that first appeared when adult study subjects with schizophrenia were 7 years old.

LOS ANGELES—January 21, 2010—The presumption that children need both a mother and a father is widespread. It has been used by proponents of Proposition 8 to argue against same-sex marriage and to uphold a ban on same-sex adoption.

On the other end of the political spectrum, Barack Obama endorsed the vital role of fathers in a 2008 speech: "Of all the rocks upon which we build our lives, we are reminded today that family is the most important. And we are called to recognize and honor how critical every father is to that foundation."

Computer games have a broad appeal that transcends gender, culture, age and socio-economic status. Now, computer scientists in the US think that creating computer games, rather than just playing them could boost students' critical and creative thinking skills as well as broaden their participation in computing. They discuss details in the current issue of the International Journal of Social and Humanistic Computing.

A new drug for multiple sclerosis promises to change the lives of the 100,000 people in the UK who have the condition, say researchers at Queen Mary, University of London.

Newark, NJ – A new brain-based computational model is helping to understand how Parkinson's disease and dopamine medications—used to treat motor symptoms caused by the disease— can affect learning and attention.

Research performed by a scientist at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center has shown that controlled breathing at a slowed rate can significantly reduce feelings of pain.

Chronic pain sufferers, specifically fibromyalgia (FM) patients, also reported less pain while breathing slowly, unless they were overwhelmed by negative feelings, sadness or depression.

Toronto – A new study has found promising evidence that the older brain's weakened ability to filter out irrelevant information may actually give aging adults a memory advantage over their younger counterparts.

'Grid cells' that act like a spatial map in the brain have been identified for the first time in humans, according to new research by UCL scientists which may help to explain how we create internal maps of new environments.

Online quizzes are not helping students learn their subject, according to a study just published in the International Journal of Information and Operations Management Education.

(CHICAGO) – Neurobehavioral researchers at Rush University Medical Center have found three key factors in a child's behavior that can lead to social rejection. The studies are a crucial step in developing scientifically sound screening tests and treatment planning for social-emotional learning difficulties. The results from the studies are published in the Journal of Clinical Child and Adolescent Psychology.

Scientists are reporting the first evidence from human research that blueberries — one of the richest sources of healthful antioxidants and other so-called phytochemicals — improve memory. They said the study establishes a basis for comprehensive human clinical trials to determine whether blueberries really deserve their growing reputation as a memory enhancer. A report on the study appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication.

A blood test for diagnosing schizophrenia — the most serious form of mental illness — could be available this year, according to an article in the current issue of Chemical & Engineering News, ACS' weekly newsmagazine. The disorder, with symptoms that can include hallucinations and delusional thoughts, affects more than two million people in the United States and millions more worldwide.
