Scientists studying a mysterious neurological affliction in pregnant cats that have been fed irradiated food have discovered a surprising ability of the central nervous system to repair itself and restore function when placed back on a normal diet.
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

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."

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.
