Elite Soccer Players Have High Rates of Osteoarthritis
by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field
Take Home Message: Elite soccer athletes may be at an increased risk for knee and ankle osteoarthritis compared with the general population. This group should be identified as high risk and preventative measures should be taken.
While participation in elite-level sports is often viewed as a good thing, there is an established increased risk of short-term injuries (e.g., sprains, strains). This increased injury risk may leave athletes at an increased risk for long-term disability (e.g., oste........ Read more »

Four color problem, odd Goldbach conjecture, and the curse of computing
by Artem Kaznatcheev in Evolutionary Games Group
For over twenty-three hundred years, at least since the publication of Euclid’s Elements, the conjecture and proof of new theorems has been the sine qua non of mathematics. The method of proof is at “the heart of mathematics, the royal road to creating analytical tools and catalyzing growth” (Rav, 1999; pg 6). Proofs are not […]... Read more »

RDoC and the cross-roads of psychiatry
by Paul Whiteley in Questioning Answers
The Irish poet Brendan Behan is, I think, credited with the phrase: "There's no bad publicity except an obituary". One wonders how appropriate this phrase might be to the 'diagnostic Bible' (except that it isn't) which is DSM-V which is poised to make its entrance into the World in the coming days.The real Homer @ Wikipedia Indeed, the story of DSM-V even before it hits the diagnostic shelves of all good psychiatric bookshops, has the makings of an epic piece of poetry or literature, o........

Those repair crews work fast!
by Gal Haimovich in Green Fluorescent Blog
Super-resolution microscopy can potentially allow imaging of single protein molecules. A new paper now tracks single Pol and Lig proteins in E. coli, as they repair DNA damage.

Alligator stem cell study paves the way for tooth regeneration in humans
by beredim in Stem Cells Freak
Unlike most vertebrates which can replace lost teeth through their entire lives, humans come with only two sets, baby teeth and adult teeth, then they simply lose the ability for tooth renewal.. However, a new study on alligators by researchers at the Keck School of Medicine, University of Southern California (USC) may someday allow doctors to stimulate tooth regeneration in humans as well.Read More...

Coffee: Bugs and Debugging
by Aurametrix team in Irritable Bowel Blog
Coffee can bug or de-bug you - in many different ways.It can actually energize your gut bugs. Nestlé researchers showed that for sixteen healthy adult volunteers consuming a daily dose of 3 cups of coffee during 3 weeks. This led to an increase of the metabolic activity and/or numbers of Bifidobacterium species, important probiotics in the food industry. Bifidobacteria has been long suggested to be therapeutic for the relief of intestinal disorders, including Irritable Bowel Syndrome ........ Read more »

Main Point:
Researchers have found that the size of the frontal lobes of the brain is not the only crucial factor of human intelligence.
Published in:
Proceedings of the National Academy of Sciences (PNAS)
Study Further:
Frontal lobes, as the name suggest, are present at the front of each cerebral hemisphere - either of the two symmetrical halves of the front part of the brain.
Researchers have reported in the new study that size of the brain’s frontal lobe is not the onl........ Read more »

Sneaking viruses into the brain: cancer treatment
by Rebecca Nesbit in The Society of Biology blog
This week, 13th-19th May, a campaign is being launched to highlight the hidden aspects of brain injury and help with the correct diagnosis of these potentially terminal conditions. The campaign is part of Action for Brain Injury (ABI) week, organised by Headway.
Brain injury is an umbrella-term for a number of conditions, including brain trauma, stroke and brain tumours. These conditions can often go unnoticed externally, yet are extremely damaging internally. It is therefore vital that GPs c........ Read more »

Cheating Your Way to Extinction
by gunnardw in The Beast, the Bard and the Bot
For a long time, it has been thought that evolutionary and ecological research were quite separated from each other. After all, evolution takes place on long timescales while ecological events usually happen much faster. At least, that was the common perception. Lately, however, it has become clear that, in some cases, the relevant timescales in […]... Read more »

Ostracism Hurts: The Psychological Costs of Ignoring or Excluding Others
by Dan DeFoe in Psycholawlogy
People who ostracize – ignore or exclude – others incur psychological costs. Researchers who recently explored whether people suffer psychological costs when they comply with social directives to ignore or exclude cause others reached that conclusion. The pressure to ignore or exclude someone has become an “all too common” experience, and the authors noted [...]The post Ostracism Hurts: The Psychological Costs of Ignoring or Excluding Others appeared first on Psychol........

Engaging lecturers can breed overconfidence
by Christian Jarrett in BPS Research Digest
Can fluent presenters makelearning feel too easy?
Eloquent and engaging scientific communicators in the mould of physicist Brian Cox make learning seem fun and easy. So much so that a new study says they risk breeding overconfidence. When a presenter is seen to handle complicated information effortlessly, students sense wrongly that they too have acquired a firm grasp of the material.
