This may seem pretty random, but I point you toward this post for a couple of reasons. 

First, it is, to me, a superior example of explaining esoteric math in a fashion that nonscientists can understand. It is very hard — I never really know how incomplete my knowledge is until I have to explain it to readers making no claim on that knowledge. IMO, George Dallas shows how well he knows his subject.

It is passe, if not cliche-ish, to say that MRI images of the brain show similar activity for some people shown food images compared with cocaine addicts shown coke images.

But a study at Dartmouth College — published April 18 in The Journal of Neuroscience — goes a step further, using images from the brain’s rewards center to predict who is likely to gain weight six months hence.

Not only that, but researchers used the same technique to predict sexual desire.

I can't say I understand how it works, or its implications, but I am intrigued by this story about European scientists working on metabolic typing, which the story says could lead to personalized nutrition.
