Hey, everybody.  I’m posting an awesome video lecture by a researcher named Bonnie Bassler.  Bassler is a molecular biologist at Princeton University.  In 2001, she discovered that bacteria use a form of group communication that researchers now call quorum sensing.  It’s like birds in a flock somehow knowing which way to turn all at once.  It’s a small observation that carries huge implications for medicine.  Bassler is a great speaker, and you should enjoy it no matter what your science background.

There are two versions, depending on how much time you have.  The longer is more complete, and talks more about the implications, but it’s 74 minutes.  If you want a quick and dirty version, try the shorter one first.  Enjoy!
