In 1966, when the "Star Trek" television show debuted, it was revolutionary - not just in the ways that are commonly stated, like that it took a stand against racism and petty geopolitics, we had Sidney Poitier and The Man From U.N.C.L.E. by then, but rather what it did for science.

In the post-World War II era, science had gone from being a well-respected endeavor to being 'mad'. This was after Harry Harlow's monkey isolation experiments,  after LSD on unwitting subjects, after the atomic bomb and after the forced sterilization of 60,000 people under the label of science.

A dress that seems to be different colors to different people has all the Internet intrigued - and that's a good thing. It's a good way to understand science and psychology.

There are two hypotheses as to why people see dramatically different things; one is that our brains are constantly being bombarded by information and so we end up making a lot of assumptions and interpretations based on parameters. If you are looking up close at something and infer a blue background, you see the dress differently than people who assume it has an artificial light background, like yellow.

Though adopting a whole-food diet has become popular in some circles, is it really going to help you? Perhaps, perhaps not. 

One reason to err on the side of caution and not chase diet fads is that fads tend to be expensive and their benefit is unknown. A gluten-free diet, for example, will be 242 percent higher cost and the extra sugar, extra fat, hydroxypropyl methyl cellulose and xanthan gum in gluten-free foods are not a health positive.

What about the whole food diet?
