From this week's C&EN, all sorts of good stuff:
- Lauren Wolf's really interesting feature on caffeine levels in drinks and toxicity. (Did you know that Cracker Jack was going to come out with a caffeinated version?)
- More on the current helium shortage from Marc Reisch, including a quench on a 600-MHz at University of Nebraska-Lincoln?
- We're exporting a lot of chemicals, according to Glenn Hess. Effects of a cheap dollar?
- There's been a lot of STEM immigration skepticism in the letters at C&EN.
