Add Exercise or an Antidepressant for Depression?

by William Yates, M.D. in Brain Posts

Although the psychological benefits of exercise are well recognized, the role of exercise in the treatment of psychological disorders is less clear.  Randomized control trials are limited and so clinicians are left without much data to advise patients on the proper role of exercise in a comprehensive treatment program.Madukar Trivedi and colleagues recently published a study of exercise therapy in a group of individuals with major depressive who had not reached complete remission of depress........

Building Cartilage Scaffolds the Microfluidic Way

by Hector Munoz in Microfluidic Future

CartilageOur bodies are pretty much amazing. We can get hurt, and our bodies will heal our cuts and bones (with the right support). But not everything heals so easily, like cartilage. The cartilage in our joints is called hyaline cartilage and can be damaged from trauma or diseases like osteoarthritis. The other cartilages like elastic cartilage (found in our ears and nose) and fibrocartilage (found on tendons and ligaments) are a bit of a different story. The hyaline cartilage found on the arti........ Read more »

Narcissists know they're narcissists

by Psych Your Mind in Psych Your Mind

While positive self-views are generally considered healthy, adaptive, and attractive, OVERLY positive self-views often have social costs. For example, when I asked my friend’s boyfriend if his classes this semester were challenging, he responded as follows: “I’ve done better than EVERY OTHER student in EVERY SINGLE grad class that I’ve taken. I certainly don’t except my classes this semester to be a problem.” If you’re like me, this statement made you shudder. The sense of........ Read more »

This is what a good leader does not look like

by Doug Keene in The Jury Room

Narcissists are often gregarious and social upon first meeting. They make a good initial impression. When I was learning about personality disorders in grad school we used to joke that they are wonderful on first dates, and a nightmare after that. But that good first impression wears thin over time and we find ourselves wondering [...]

Are job selection methods actually measuring 'ability to identify criteria'?

by Alex Fradera in BPS Occupational Digest

While we know that modern selection procedures such as ability tests and structured interviews are successful in predicting job performance, it's much less clear how they pull off those predictions. The occupational psychology process – and thus our belief system of how things work - is essentially a) identify what the job needs b) distil this to measurable dimensions c) assess performance on your dimensions. But a recent review article by Martin Kleinman and colleagues suggests that in some ........ Read more »

The Mystery of the Meat Sweat!

by Stuart Farrimond in Dr Stu's Science Blog

Another meal, another medical mystery… As I savoured the dying moments of the summer bank holiday, I was relishing the last few mouthfuls of a marvellous and hearty meaty meal. Then as the sun started to set, that dreaded line finally came: “Hey, I’ve got a question for your blog!” Now something of a running … Continue reading »... Read more »

New Dogfish Species Found in Taiwanese Fish Market

by Chuck in Ya Like Dags?

The Order Squaliformes, home to the dogfish sharks, is one of the most diverse groups of sharks currently swimming the oceans, second only to the Carcharhiniformes in sheer number of species. Within that order is the Family Squalidae, made up of the very familiar spiny dogfish Squalus acanthias (the star of this blog) and a bunch of species that look pretty similar to it. New species tend to pop up in this group, since most of these sharks look pretty similar and the majority of them live in t........ Read more »

Multimillennial Neanderthal occupation at La Cotte de St. Brelade

by Julien Riel-Salvatore in A Very Remote Period Indeed

The BBC has a brief news story about some of the results of new excavations conducted at the site of La Cotte St. Brélade (Jersey, Channel Islands). The site is perhaps most famous for having yielded clear evidence for the systematic slaughter of mammoths and wooly rhinos by Neanderthals, which prompted a reevaluation of their hunting abilities (Scott 1980). That analysis, however, suggested that... Read more »

Obesity, Inflammation and Depression

by William Yates, M.D. in Brain Posts

Obesity commonly occurs in the context of markers of inflammation.  Additionally, there is increasing evidence of a link between depression and systemic markers of inflammation such as the cytokine marker interleukin-6 (IL-6).  How these three conditions might tie together is an important research question.Capuron and colleagues from France recently published a manuscript that looked at a specific group with obesity--women who were severely or morbidly obese and were waiting for gastri........

Long Lost Relative of Ticks Pops Up Again

The Embodiment of Time, Tenderness, and Weight

by Sam McNerney in Why We Reason

I’ve been hearing it for years now – the brain is “embodied“. It’s a strange concept. I understand that brains aren’t disembodied, and Descartes was horribly wrong to suggest that, “there is a great difference between mind and body, inasmuch as body is by nature always divisible, and the mind is entirely indivisible.” But what [...]...

Astonishing Results in Science (the magazine)

by Allison in Dormivigilia

Last week's issue of Science focused on education and social reform. In a series of baffling, yet informative original research reports, PIs uncovered substantial racial disparities in awarded NIH grants that severely disadvantage blacks and also that there is a research lesson to be learned from teaching as a graduate student. Finally, a recent study found a positive correlation between journal impact factors and the number of article retractions....which I guess isn't terribly shocki........ Read more »

An impressive slug

by Africa Gomez in BugBlog

A showery day, I come across this enormous Arion slug crossing the garden path. It must be close to 15 cm. Identification to species level is difficult to impossible as they are distinguishable by examination of internal genitalia characters - or molecular genetic analysis, and hybrids are common. British large Arion slugs are made of several species complexes, Arion ater/rufus A. lusitanicus and A. flagellus. Both groups are very polymorphic slugs, from almost white to ........
