A protein known as Sp2 is key to the proper creation of neurons from stem cells, according to researchers at North Carolina State University. Understanding how this protein works could enable scientists to "program" stem cells for regeneration, which has implications for neural therapies.

People's memory for Facebook posts is strikingly stronger than their memory for human faces or sentences from books, according to a new study.
The findings shed light on how our memories favour natural, spontaneous writing over polished, edited content, and could have wider implications for the worlds of education, communications and advertising.
Some children who are accurately diagnosed in early childhood with autism lose the symptoms and the diagnosis as they grow older, a study supported by the National Institutes of Health has confirmed. The research team made the finding by carefully documenting a prior diagnosis of autism in a small group of school-age children and young adults with no current symptoms of the disorder.
Philadelphia, PA, January 15, 2013 – Originally, the label "borderline personality disorder" was applied to patients who were thought to represent a middle ground between patients with neurotic and psychotic disorders. Increasingly, though, this area of research has focused on the heightened emotional reactivity observed in patients carrying this diagnosis, as well as the high rates with which they also meet diagnostic criteria for posttraumatic stress disorder and mood disorders.
Researchers at North Carolina State University have come up with a technique to embed needle-like carbon nanofibers in an elastic membrane, creating a flexible "bed of nails" on the nanoscale that opens the door to development of new drug-delivery systems.
It is well known that violent adults often have a history of childhood psychological trauma. Some of these individuals exhibit very real, physical alterations in a part of the brain called the orbitofrontal cortex. Yet a direct link between such early trauma and neurological changes has been difficult to find, until now.
WASHINGTON, January 14, 2013─New research synthesizes studies of English reading outcomes for Spanish-dominant English language learners (ELLs) in elementary schools. The review, Effective Reading Programs for Spanish-dominant English Language Learners (ELLs) in the Elementary Grades: A Synthesis of Research, appears in the December issue of Review of Educational Research, a journal of the American Educational Research Association (AERA).
Nations that consume a lot of milk and milk products also tend to have a lot of Nobel laureates among their populations, suggest the authors of a letter, published in Practical Neurology.
Research published last year in the New England Journal of Medicine reported a strong association between a nation's chocolate consumption and Nobel laureate prowess, speculating that the flavonoid content of chocolate was behind the boost in brain power.
An effort to develop software that unravels the complexities of how proteins fold is paying dividends in new findings on how they misfold, according to researchers at Rice University.
The study published this week in the Proceedings of the National Academy of Sciences by chemist Peter Wolynes and his team at Rice's BioScience Research Collaborative should be of particular interest to those who probe the roots of degenerative diseases associated with the aggregation of amyloid fibers in the body. These include Alzheimer's and Parkinson's diseases and Type 2 diabetes.
Researchers at the Yerkes National Primate Research Center, Emory University, are the first to show chimpanzees possess a sense of fairness that has previously been attributed as uniquely human. Working with colleagues from Georgia State University, the researchers played the Ultimatum Game with the chimpanzees to determine how sensitive the animals are to the reward distribution between two individuals if both need to agree on the outcome.
A study based at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) finds that the local functional connectivity of the brain – the extent to which the activity of within a small brain region appears to be coordinated – is reduced in individuals with autism spectrum disorders (ASD). Although it has been recognized for several years that functional connectivity between separate areas of the brain was reduced in ASD, it had been assumed that local functional connectivity was actually higher in the brains of autistic individuals.
Parkinson's experts across the world have been reporting a remarkable phenomenon — many patients treated with drugs to increase the activity of dopamine in the brain as a therapy for motor symptoms such as tremors and muscle rigidity are developing new creative talents, including painting, sculpting, writing, and more.
Interneurons – nerve cells that function as 'dimmers' – play an important role in the brain. Their formation and migration to the cerebral cortex during the embryonic stage of development is crucial to normal brain functioning. Abnormal interneuron development and migration can eventually lead to a range of disorders and diseases, from epilepsy to Alzheimer's. New research by Dr. Eve Seuntjens and Dr.
Nature's ability to create iridescent flowers has been recreated by mathematicians at The University of Nottingham. The team of researchers have collaborated with experimentalists at the University of Cambridge to create a mathematical model of a plant's petals to help us learn more about iridescence in flowering plants and the role it may play in attracting pollinators.
Philadelphia, PA, January 14, 2013 – Bipolar disorder is a severe mood disorder characterized by unpredictable and dramatic mood swings between the highs of mania and lows of depression. These mood episodes occur among periods of 'normal mood', termed euthymia.
Prior research has clearly shown that brain emotion circuitry is dysregulated in individuals diagnosed with bipolar disorder. It is thought that these disturbances impair one's ability to control emotion and contribute to mood episodes.
