First RCT of Vitamin D supplementation in MS shows no benefit of high dose.

Recently reported in Neurology (and available to the public) this was a small trial of short duration of patients with established MS.  Nevertheless, it shows no benefit, and the direction of effect was towards harm, though it was insignificant.  So, while Vitamin D deficiency appears to be causally related to onset of MS, high-doses of D, which raise blood levels to 40ng or more, don't appear to help.  An interesting "patient page" lays out the strengths and weaknesses of the study.

The best summary of the causes of the financial crisis

The Washington Post's Sunday business section had a wonderful piece by Barry Ritholtz on the causes of the meltdown:  The Big Lie.
He could have made more of the long-running idiocy of the SEC that anointed the three ratings agencies (S&P, Moodys and Fitch) as the only "nationally recognized" sources of bond ratings, thereby requiring pension funds and insurance companies to rely on those ratings for SEC compliance, and at the same time taking the pension fund managers off the hook for failure -- "What else could I do?  I had to rely on the ratings agencies.  Besides, if I had to do more work, I wouldn't have been able to go home to my beautiful family and our house in the Hamptons (or Martha's Vineyard, take your pick) on the weekends."

Here's some charts he put up on his web site as of 11-20-2011. Ritholtz Charts

The state of the global economy, by Joseph Stiglitz

Much has been made of his nobel prize in Economics, but let's face it...there are now a lot of those running around.  Nevertheless, I always find his papers and remarks understandable, which is a big thing in my view.
Here he has a sort of radical idea for saving the world economy, and he also puts the "state of" in an excellent perspective.
Here it is:  Stiglitz World Bank Talk
