Greetings–

I was traveling for much of this week on a reporting trip, part of which I spent suited up in the outfit you can see above. So I don’t have a Matter column this week. Instead, let me direct your attention to the second installment of my “Science Happens” video series for STAT. I pay a visit to a lab where scientists are trying to engineer bacteria to heal our microbiomes.

As always, if you have friends you think would enjoy getting this newsletter, please tell them to sign up at http://tinyletter.com/carlzimmer.

You can also follow me on TwitterFacebook , LinkedIn, and Google+. And there’s always carlzimmer.com.

Best wishes, Carl
