In a study published today (March 30, 2009) in the Proceedings of the National Academy of Sciences, a team of researchers from the University of Wisconsin-Madison reports that the restoration in cats of myelin - a fatty insulator of nerve fibers that degrades in a host of human central nervous system disorders, the most common of which is multiple sclerosis - can lead to functional recovery

Relationship between low ultraviolet B irradiance and higher breast cancer risk in 107 countries. Mohr SB, Garland CF, Gorham ED, Grant WB, Garland FC. Breast J. 2008 May-Jun;14(3):255-60. Epub 2008 Apr 17. PMID: 18422861 DOI: 10.1111/j.1524-4741.2008.00571.x There was a protective effect of UVB irradiance on risk of breast cancer that was independent of fertility rate, proportion of the population overweight, alcohol intake, animal energy intake, and other covariates.

"In 1927 a controversy arose in the athletic world. The German Swimmers' Association had decided to use a sunlamp on their athletes to boost performance. Some felt this ultraviolet irradiation constituted "athletic unfairness." In other words, doping."

ncident invasive breast cancer, geographic location of residence, and reported average time spent outside. Millen AE, Pettinger M, Freudenheim JL, Langer RD, Rosenberg CA, Mossavar-Rahmani Y, Duffy CM, Lane DS, McTiernan A, Kuller LH, Lopez AM, Wactawski-Wende J. Cancer Epidemiol Biomarkers Prev. 2009 Feb;18(2):495-507. Epub 2009 Feb 3. PMID: 19190147 doi: 10.1158/1055-9965.EPI-08-0652 In conclusion, region of residence and geographic solar irradiance are not consistently related to risk of breast cancer and may not be sufficient proxy measures for sunlight/vitamin D exposure. The observed association between time spent outside and breast cancer risk support the hypothesis that vitamin D may protect against breast cancer.
