I am allegedly some sort of scientist. So it’s only responsible that I blog about science once in a while. I promise to weed out boring stories, as well as stories so sensational everyone would have heard about them, and try and bring you stories where a non-scientist might not realize how freaking cool that finding is.
NPR does a good job of this, and I confess that the inspiration for today’s post was from today’s All Things Considered. However, no one aged 65 or younger listens to NPR except me, so I feel good about being a liaison here.

Today’s Post on Science (PoSci – let’s pronounce it “Poe-see”) is about bacteria. That talk!
There is a species of bacteria called Vibrio harveyi that scientists discovered act in a peculiar way. When a single bacterium of this species (I’ll call him Harvey) is alone, he pretty much just sits there. The only thing he does (besides the normal day-to-day maintenance he does to live) is send out chemicals (like a “chirp” in Boost Mobile terms) to see if any other Harveys are out there, and if so, please holla back. If other Harveys come near, they pick up each others’ signals until they get a big enough gang (a “quorum” in scientific terms), and then…they begin to glow. The glowing is actually a by-product of all the genes (100 or so) that get turned on and off, the net result of which is that the many Harveys being to to act as one huge organism.
This shit is cooler than Hypercolor t-shirts!
Pretty cool in itself, right?
Cool thing #2 – Bonnie Bassler, who together with Michael Silverman discovered this phenomenon, then went on to discover that not just Harveys, but all bacteria can talk within their species in this manner. They communicate, group together, and carry out all sorts of activities besides glowing, such as…making you sick! Neato! Bonnie describes it best:
“Melissa Miller, a graduate student in the lab, went on to show that cholera has a circuit like Vibrio harveyi‘s and what it does, it doesn’t make light, it makes toxins, and so that’s what it does as a group,” Bassler explains. “So they can’t make you sick as one, but if they wait and they launch their attack together, it’s fantastic.” Source: “A Biologist’s Listening Guide to Bacteria” by Richard Harris, All Things Considered, NPR News, September 12, 2006.
Fantastic indeed. Cool thing #3 – Bassler THEN went on to discover that not only do members of bacteria species talk to one another, ALL species of bacteria can talk to ALL species of bacteria! Think about how remarkable this is! It’s as if humans could talk to dogs (“fucking STOP jumping on me, OK buddy????”) or birds (they would probably get sick of being asked, “How does it feel to fly?”) or snails (“I’m going to eat you now, after I dump you in some garlic.”), and they could TALK BACK! (“I just FUCKING LOVE YOU SO FUCKING MUCH!,” “I dunno, it’s aight, I guess,” and “Noooooooooo!” respectively).
OK, actually a more appropriate analogy would be that it would be more like if we could communicate with other ape species such as chimps or bonobos. Still pretty cool, don’t you think? [Dane Cook fans nod enthusiastically here]
This is how it works.
The coolest thing about Bonnie Bassler, however, is this: Bonnie is an aerobics instructor. Why is this the coolest? Because *I* am an aerobics instructor, too! I am a bonafide “group exercise leader” certified through the American Council on Exercise. I think scientist + aerobics instructor is a great combination. Just like little bacteria Harveys, I’m hoping that nerdy scientist aerobics instructors can band together to rule the world.
Bonnie, you’re my hero
I bring the same nerdy intensity to aerobics as I do to my research. I practice my step aerobics routines in the stairwell between my 4th floor office and my 3rd floor lab. I have cataloged all my kickboxing sequences (such as jab-jab-cross, lunge, hook, lunge, uppercut) in a gigantic kickboxing database. I just today had a two-hour conversation with a triathlete about the biomechanics of the pedal stroke (I teach spinning, too), and whether it was possible to hit 100% efficiency or if that was biomechanically impossible.
The moral of this story is this: bringing a little science into our world is a great thing. It makes for better aerobics classes. It makes for pretty glowy things. And, one day, it might help us talk to our pets.
