Butter better than margarine? New study says saturated fats not tied to heart disease.

by Yoni Freedhoff in Weighty Matters

You've got to love evidence-based nutrition.And if you're not sure why, here's a reason - last week it concluded that butter's not inherently bad for you.You see last week the American Journal of Clinical Nutrition released a meta-analysis that looked at all the prospective epidemiological studies looking at the relationship between dietary saturated fat intake and the risks of developing coronary heart disease, stroke and cardiovascular disease.What did they find? 21 studies with followups of 5........

Sherlock Holmes and Proteomics

by Abhishek Tiwari in Fisheye Perspective

By reading the title of the post you may be curious that what remote similarity proteomics can share with Sherlock Holmes? Well not much at this moment except the complexity of storyline. An excerpt from a bit old article, interested readers will find it useful to understand the complexity of proteomeModern proteome analysis is a very complex 'detective story', which might baffle even the most famous investigator, Sherlock Holmes [1]. The reason is that, in any proteome, a few proteins dominate ........ Read more »

The Linguistic Evidence for Navajo Origins

by teofilo in Gambler's House

Although it can be rather difficult to define what it means to be Navajo, it is quite clear from a variety of lines of evidence that speakers of Athapaskan languages, including Navajo and the various Apache languages, have not been in the Southwest for very long compared to most of the other language groups there, [...]...

No chance Europe will recover fish stocks

by CJA Bradshaw in ConservationBytes

Alternate title: When pigs fly and fish say ‘hi’.
I’m covering a quick little review of a paper just published online in Fish and Fisheries about the two chances Europe has of meeting its legal obligations of rebuilding its North East Atlantic fish stocks by 2015 (i.e., Buckley’s and none).
The paper entitled Rebuilding fish stocks no [...]... Read more »

Why Do We Think We Like Hourglass Figures?

by Wayne Hooke in The Psychology of Beauty

BMI – the ratio of body mass to height, typically correlates well with ratings of body attractiveness. WHR – a direct comparison of waist and hip measurements – also correlates with attractiveness. Recent research that compares the relative strengths of the two ratios generally finds that variation in BMI accounts for a greater proportion of [...]... Read more »

When in danger, when in doubt, just remember – deep breath in, deep breath out

Come to think of it, I have worked with some great physiotherapists (please don’t let them know!).  Anyway, it’s been one of those sayings that I’ve carried with me ever [...]... Read more »

Early modern human parietal art at Fumane Cave

by Julien Riel-Salvatore in A Very Remote Period Indeed

The last three issues of the 2009 volume of L'Anthropologie are dedicated to prehistoric art, and one the papers contained in that special volume concerns five vault fragments from Fumane Cave (Veneto region, Italy) that were recovered during excavation and that bear designs made in red ochre. The art itself is already well known and has been published in great detail as part of a monograph a few years ago (Broglio and Dalmieri 2005), but this study presents some new data on the likely age of t........

Mirror Neurons: Resonant Circuitry in Brain?

by Amiya in Physiology physics woven fine

Back in the time of the “black and white” motion picture days, when “talkies” weren’t even born, we still could make out the essence of what Charlie Chaplin had to “say”. We understood his unspoken words, courtesy a system of neuronal networking, called the mirror neuron system. Another example: you observe a man kissing ‘his’ girlfriend, ‘your’ neuronal network that would otherwise activate when you ‘actually’ kissed her, would fire! Mirror neurons are at work. Seems t........ Read more »

Coping with Trauma – Lessons from Resilient Individuals

by Shaheen Lakhan in Brain Blogger

Most individuals at some point of their life experience events that are stressful. While some people seem to crumble to the deleterious effects of stress, others sail through adverse situations. Chronic or acute stress is associated with a wide range of psychosocial disorders. So what are the factors and the possible neurobiological mechanisms associated with [...]... Read more »

Focusing students' attention on the relevance of science improves educational outcomes

by Katherine Porter in Galley Proofs

In the discussion about improving science education, the focus often falls on large-scale programs. However, some studies are suggesting that even short-term, small interventions in classrooms can have significant effects on student achievement. In the 4 December 2009 issue of Science (okay, I'm a little behind in my reading...), Hulleman and Harackiewicz investigate the efficacy of short writing assignments on student interest and achievement in science.It's generally well accepted (and logical........

The journal article of the future!

by Zen Faulkes in NeuroDojo

Elsevier is trying a new format for research articles here and they are, somewhat pretentiously, calling it the “article of the future.” It’s always risky to attach “future” to these sorts of things, as it tends to get people bitching that they don’t have their flying cars and personal jet packs yet.

As far as I can tell, Elsevier’s experiment seems to be confined to one of its big flagship journals, Cell, for now. An example is here, which I like becau........ Read more »

Witnessing school bullying carries its own psychological risks

by Christian Jarrett in BPS Research Digest

We hear a lot about the harmful consequences to children of seeing their parents argue or watching violence on TV, but very little about the potential harm of witnessing school bullying. But now Ian Rivers and colleagues have published findings suggesting that being a bystander to bullying can often be just as psychologically harmful as being directly involved.The researchers asked just over 2000, predominantly white, children aged 12-16 at 14 state schools in the north of England about how much........
