There are some amazing and inspiring science types on Twitter, many of whom have pulled together quite a crowd of followers. With the current craze for twitter lists, I migrated as many as I could from the original scientwists list to the new system, but there’s a limit of 500 per list, so I also categorized them into bio, chem, phys etc.

Interestingly, Listorious now orders list members according to Twitter follower count. It’s not a great metric for ones twitteriness, but it can be useful. So, here’s a list of the Top 32 by followers from the scientwists list, all worth following regardless of by how much store you set twittercount:
