Using advanced brain imaging, researchers have matched certain behavioral symptoms of schizophrenia to features of the brain’s anatomy. The findings, at Washington University School of Medicine in St. Louis, could be a step toward improving diagnosis and treatment of schizophrenia.... Read more »

Researchers have imaged in unprecedented detail the three-dimensional structure of supercoiled DNA, revealing that its shape is much more dynamic than the well-known double helix.
Various DNA shapes, including figure-8s, were imaged using a powerful microscopy technique by researchers at the Baylor College of Medicine in the US, and then examined using supercomputer simulations run at the University of Leeds.... Read more »

A new study from the Gladstone Institutes shows that a single drop of blood in the brain is sufficient to activate an autoimmune response akin to multiple sclerosis (MS). This is the first demonstration that introduction of blood in the healthy brain is sufficient to cause peripheral immune cells to enter the brain, which then go on to cause brain damage....

In 2009, Google made available Google Books (also known as the Ngram corpus), a database that now includes over 8 million books from libraries around the world. The books comprise a collection of words (over 500 billion English words) and phrases and this dataset is freely available for research use. The Books corpus allows researchers to examine changes in the frequency of word use in books over time, dating back to 1800.
This has led a lot of striking findings. So for instance, it has b... Read more »

Chronic pain results from disease or trauma to the nervous system. Damaged nerve fibres with heightened responses to normal stimuli send incorrect messages to pain centres in the brain. This phenomenon, called “peripheral and central sensitization” is one of the key mechanisms involved in the condition which touches people with diabetes, cancer, and those suffering from multiple sclerosis, among others....

Predatory Open Access publishers on the rise

The increase in so-called “predatory” Open Access publishers is posing a threat to the integrity of Open Access publishing. Predatory Open Access publishers charge authors high publishing fees without providing proper editorial and peer review services. They are abusing the opportunity created by the Gold Open Access publishing model which requires authors to pay article processing charges.... Read more »

It is now well-established that social class is positively related to mental health. However, researchers remain unclear about the specific processes that underlie the relation between social class and depression. In some recent research, we investigated the potential roles of parenting style and friendship in explaining the relationship between social class and mental health.... Read more »

Parents who are more anxious and emotional can impact the amount of violent video games their children play, according to new consumer research from Iowa State University. Russell Laczniak, a professor of marketing and the John and Connie Stafford Professor in Business, says given the harmful effects of violent video games, he and his colleagues wanted to better understand how parents influence children’s behavior....

A new study finds that rising placebo responses may play a part in the increasingly high failure rate for clinical trials of drugs designed to control chronic pain caused by nerve damage. Surprisingly, however, the analysis of clinical trials conducted since 1990 found that the increase in placebo responses occurred only in trials conducted wholly in the U.S.; trials conducted in Europe or Asia showed no changes in placebo responses over that period....

The human brain does not come with an operating manual. However, a group of scientists have developed a way to convert structural brain imaging techniques into “wiring diagrams” of connections between brain regions. Three researchers from UCSB’s Department of Psychological & Brain Sciences — Michael Miller, Scott Grafton and Matt Cieslak — used the structure of neural networks to reveal the fundamental rules that govern which parts of the brain are most able to exert cognitive control over thoughts and actions....

Everyone knows that exercise improves health, and ongoing research continues to uncover increasingly detailed information on its benefits for metabolism, circulation, and improved functioning of organs such as the heart, brain, and liver. With this knowledge in hand, scientists may be better equipped to develop “exercise pills” that could mimic at least some of the beneficial effects of physical exercise on the body. But a review of current development efforts ponders whether such pills will achieve their potential therapeutic impact, at least in the near future.... Read more »

Well bad news for those of us who have a sweet tooth, a diet high in processed fructose sabotages rat brains’ ability to heal after head trauma, UCLA neuroscientists report.

In pop culture, conspiracy believers — like FBI agent Fox Mulder on The X Files or professor Robert Langdon in The Da Vinci Code — tend to reject the notion of coincidence or chance; even the most random-seeming events are thought to result from some sort of intention or design. And researchers have suggested that such a bias against randomness may explain real-world conspiracy beliefs. But new research from psychological scientists shows no evidence for a link between conspiracist thinking and perceptions of order, design, or intent.... Read more »

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have uncovered a significant–and potentially treatable–relationship between a chemical that helps transmit signals in the brain and genetic mutations present in a subset of individuals with autism spectrum disorder.
