Every once in a while, I'm reminded of how much of a geek I really am. Case in point:  The fantastic and always readable Carl Zimmer posted this piece on his blog about recent developments in the 25-year, 59,000 generation E. coli evolution experiment occurring in the Lenski laboratory at the University of Michigan.

Always on the lookout for things I can use in AP Bio, I took the original blog post, and slapped a few active exercises on the end for my students.  When it was done, I figured I could post a link to the activity on twitter, as I participate in a somewhat-significant community of biology teachers on said medium:

Wouldn't you know it, the man himself, figured it was worth a re-tweet.

Yay!

Such are the highlights in the life of a science teacher, recently finished with the first full week of teaching in the new year.

Have a lovely weekend, all!

Update (1.13):  I was pleasantly surprised to discover that the above-mentioned assignment had come to the attention of Dr. Lenski, as well.  So not only has this activity gotten some "Zimmer props", it's also now "Lenski-approved"!

How great is it to be able to teach in this age, where the scientists and writers you are using with your kids are literally a tweet away!
