"These findings clearly state that there is a relationship between summer suicide rates and biochemical (e.g., plasma L-TRP and melatonin levels, [3H]paroxetine binding to blood platelets), metabolic (serum total cholesterol, calcium and magnesium concentrations), and immune (number of peripheral blood lymphocytes and serum sIL-2R) variables.[18] Another study focused on the association between depression, suicide, and the amount of polyunsaturated fatty acids (PUFA). They state that "depression is accompanied by a depletion of n-3 poly-unsaturated fatty acids".[22] Their methodology involved taking periodic blood samples-every month for one year-of healthy volunteers, allowing them to analyze the "PUFA composition in serum phospholipids and [relating] those data to the annual variation in the mean weekly number of suicides". They used an analysis of variance (ANOVA) to document their results, finding that PUFA like arachidonic acid, eicosapentaenoic acid, and docosahexaenoic acid all occurred at significantly lower rates in winter than in summer months. The association between depression, suicide, and PUFA rates is indicative of there being a biological factor in seasonal effects on suicide rates"

"It seems like his brain isn't working quite properly and according to new findings, it may not be. Researchers have begun to explore the cognitive impairment that men experience before and after interacting with women. A 2009 study demonstrated that after a short interaction with an attractive woman, men experienced a decline in mental performance. A more recent study suggests that this cognitive impairment takes hold even w hen men simply anticipate interacting with a woman who they know very little about. Sanne Nauts ... Daisy Grewal is a researcher at the Stanford School of Medicine, where she investigates how stereotypes affect the careers of women and minority scientists."

Powerful and extensible JS data grid and explorer built on Backbone. Recline combines a data grid, Google Refine-style data transforms and visualizations all in lightweight javascript and html. Designed for standalone use or as a library to integrate into your own app. Recline builds on the powerful but lightweight Backbone framework making it extremely easy to extend and adapt and its modular design means you only have to take what you need.

"The molecule PKR (the double-stranded RNA-activated protein kinase) was originally described as a sensor of viral infections, but its function in the brain was totally unknown," said Dr. Mauro Costa-Mattioli, assistant professor of neuroscience at BCM and senior author of the paper. Since the activity of PKR is altered in a variety of cognitive disorders, Costa-Mattioli and colleagues decided to take a closer look at its role in the mammalian brain. Super memory The authors discovered that mice lacking PKR in the brain have a kind of "super" memory. "

William Gunn The Top 10 papers in Biological Sciences by Mendeley readership. With the Mendeley for Life Scientists webinar coming up on Thursday, I thought I would take a look at the readership stats for Biological Sciences. Biological Sciences has long been our biggest discipline, and having done my doctoral work in the Life Sciences, I knew this would be interesting. Overall, researchers in bioinformatics contributed most strongly to the most read papers, along with the older disciplines of micro- and molecular biology. Regardless of discipline, however, it's clear that the days of toiling away in isolation to thoroughly study one gene are over. Today, it's all about huge consortia and massive data. Here's what I found

"We are a superficial species. And this brings me to a fascinating new paper by an all star team of psychologists, including Kurt Gray, Joshua Knobe, Mark Sheskin, Paul Bloom and Lisa Feldman Barrett.. we automatically assume that the capacity to think and the capacity to feel are in opposition. It's a zero sum game. What does all this have to do with nakedness? The psychologists demonstrated it's quite easy to shift our perceptions of other people from having a mind full of agency to having a mind interested in experience: all they have to do is take off their clothes."

"In our recent paper, we take a different approach. We consider how measurements work in the macroworld, finding that some quantum features are simply unobservable. Most remarkably, this approach shows that something called quantum nonlocality disappears for objects big enough to contain roughly the Avogadro number of atoms-the number of atoms you'd expect in a few grams of matter."

"Academics have to publish in high-Impact Factor journals to receive promotions, tenure, or grant funding, and universities allocate their million-dollar library budgets to those same high-Impact Factor journals. This is despite the Impact Factor's many known flaws - the most limiting of which is that the citations it is based on take 3-5 years to accumulate"

"Slow science was pretty much the only science conceivable for hundreds of years; today, we argue, it deserves revival and needs protection. Society should give scientists the time they need, but more importantly, scientists must take their time."

Tabula will be platform and content agnostic, working with as many brands and versions of tablet computers as possible. Of course, compatibility takes coding hours, so we'll start with one or two platforms and build from there. But let's just say we fully recognize the value of high-end and lower-cost hardware when it comes to solutions to help schools thrive.

"Formal education must adapt to these changes, taking advantage of new strengths in visual-spatial intelligence and compensating for new weaknesses in higher-order cognitive processes: abstract vocabulary, mindfulness, reflection, inductive problem solving, critical thinking, and imagination. These develop through the use of an older technology, reading, which, along with audio media such as radio, also stimulates imagination. Informal education therefore requires a balanced media diet using each technology's specific strengths in order to develop a complete profile of cognitive skills. "

"And again, in this expanded group, she found the same association between the variation of the DRD4 gene and a willingness to take risks on the slopes. The variant's overall effect was slight, explaining only about 3 percent of the difference in behavior between risk takers and the risk averse, but was statistically significant and remained intact"

"We build and investigate software systems for parallel and distributed environments. We have conducted research in operating systems, networking, mobile computing, language design, compiler design, and architecture, taking a pragmatic approach: we build high-performance, reliable, and working systems."

In our Universe, a black hole is bounded by a spherical surface called an event horizon. Whereas in ordinary three-dimensional space it takes a two-dimensional object (a surface) to create a boundary inside a black hole, in the bulk universe the event horizon of a 4D black hole would be a 3D object - a shape called a hypersphere. When Afshordi's team modelled the death of a 4D star, they found that the ejected material would form a 3D brane surrounding that 3D event horizon, and slowly expand. The authors postulate that the 3D Universe we live in might be just such a brane - and that we detect the brane's growth as cosmic expansion. "Astronomers measured that expansion and extrapolated back that the Universe must have begun with a Big Bang - but that is just a mirage," says Afshordi.

"For me, the picture that emerges is one in which chronic inflammation caused by poor oral health sets the stage for more serious illness. (See my earlier post for more info about the connection between inflammation and cancer.) I think further research will probably turn up some surprising connections between oral bacteria and cancer, but we don't have to wait for additional research to begin taking oral hygiene seriously as a potential way to head off cancer and CVD."
