Back in the days when I used to maintain this blog (so, quite a few years ago), I occasionally wrote about helium. Many people are surprised to learn that helium, the stuff of party balloons and superconducting magnets for particle accelerators (and many dozens of other uses), is a slowly dwindling non-renewable resource.

The November 2013 issue of the APS News (published by the American Physical Society) has a bit more information about the recently passed Helium Stewardship Act.

Both of these topics appeared in the news in the past week, though I wouldn’t have known if not for thoughtful readers bringing the articles to my attention.
