Have you ever had a Gus Burger? If not, you don't know what you're missing. On the surface, it would appear to be a death sentence on a plate. But nutritional science is a mess, and the Gus Burger is a good example of some of the problems. American Council advisor Dr. David Seres tells us why.

NYU physicist Alan Sokal thought very little of the research performed by his colleagues in the social sciences. To prove his point, he wrote a paper that used plenty of trendy buzz words but made absolutely no sense.

A teenager's recent death from caffeine consumption inspired this article, mainly because people may not realize that caffeine, in large amounts, can be toxic. Another inspiration was to highlight some very cool, but little known, research that tests just how toxic caffeine is. Read this – and you'll never look at a spider web the same way again.
