According to assman (yes, that's his name), porn has not become mainstream. The post is totally work-safe FYI.

Pubmed + RSS + iGoogle = Easy Lit Updates:

...The idea is to use the combined power of Pubmed, RSS feeds and iGoogle to create a page of RSS feed boxes that will keep you continually updated on articles containing your keywords of interest, or from specific authors or journals. It is nice and simple, but I find it an incredibly powerful and fast method of literature scanning compared to email updates or browsing each journal individually.

The figure above comes from the an article in The New York Times, The Genetic Map of Europe, which draws from a new paper, Correlation between Genetic and Geographic Structure in Europe. The authors sampled 2,500 Europeans across 300,000 points of genetic variation, then extracted out the components of that variation, and plotted the individual data points along the two largest independent dimensions. You note that various samples tend to cluster geographically with each other; i.e., Finns tend to cluster with other Finns, Italians with Italians. This makes sense since Europe hasn't been a random mating population, most people found mates from local regions. Sandman, Genetic Future and Dienekes have extensive comments so I'll leave it at that. But, below the fold I've taken a less stylized figure, which shows all the individuals sampled as points, and added some labels to give you a better geographical intuition.

The Daily Star in Bangladesh has published a profile I wrote of Reihan Salam.

25-Hydroxyvitamin D Levels and the Risk of Mortality in the General Population:

In cross-sectional multivariate analyses, increasing age, female sex, nonwhite race/ethnicity, diabetes, current smoking, and higher body mass index were all independently associated with higher odds of 25(OH)D deficiency...while greater physical activity, vitamin D supplementation, and nonwinter season were inversely associated. During a median 8.7 years of follow-up, there were 1806 deaths, including 777 from CVD. In multivariate models (adjusted for baseline demographics, season, and traditional and novel CVD risk factors), compared with the highest quartile, being in the lowest quartile...was associated with a 26% increased rate of all-cause mortality...and a population attributable risk of 3.1%. The adjusted models of CVD and cancer mortality revealed a higher risk, which was not statistically significant....

ScienceDaily, Low Vitamin D Levels Pose Large Threat To Health; Overall 26 Percent Increased Risk Of Death. Death due to ateriosclerosis probably isn't the strongest evolutionary force; most people who die of heart disease are past reproductive peak. But, it is noted in this, and other, research that Vitamin D levels seem to have a global influence on fitness, probably mediated through immune robusticity.
