Data from the first 5,000 UK Biobank participants taking part in the world's largest health imaging study has been released for health researchers worldwide to use in their own research. Researchers unearthed some rather complicated patterns of correlation. For example, one pattern links brain imaging to intelligence, level of education, and a set of lifestyle factors that at first appear unrelated -- including amount of time spent outdoors and how much cheese people eat. It is plausible that, taken together, these factors create a profile of socio-economic-status and its relation to the brain.
