Even if you don’t join up at http://www.chemistry.org/ you get access to current and past issues of the newsletter, chemistry headlines, and a Shockwave interactive Periodic Table. All by itself, the animated Periodic Table popup is good for hours (and hours) of fun.
Right on the front page is another interesting freature – the molecule of the week. The chemistry headlines page also has extras – image of the week, this day in chemical history, chem 101, from the vault, and What’s That Stuff? – that are all accessible to non-members. This is a great place to hang-out and learn something new everyday.
