Professor Bassler- Bonnie - You are a gifted teacher. You are the model of what a teacher should be. You obviously enjoy your work, and you enjoy telling me about it in a way that I instantly grasp it and remember it. Vibrio fischeri - See? I remember even the name of the bacteria. How often do laymen come away from an impromptu visit to a biology lecture with the just-learned name of a bacteria imprinted in their minds? I have long believed that we will eventually find all kinds of communication “circuits” in cells, bacteria, and even within the smaller parts of these. There must be feedback systems that aid in evolution itself, beyond the final test of sub-species survival. I think you may have revealed one of the most important systems. We have learned that octopi rewrite their RNA molecules and encode (apparently) something like genetic memory. Perhaps that has a role in evolution, too. But I encourage you to keep expanding your searches for more kinds of intra-cellular and inter-cellular (extra-cellular) forms of communication. I think science has been looking at process as random when in fact it’s very connected, very chatty, and very intelligent in ways we never dreamed of examining. This is incredible! Thank you so much for the video and your clear, concise way of communicating. There is something poetically just, here. Someone studying communication of any sort would be advised to understand communication on our macro-level, so that knowledge gets clearly and accurately conveyed to the recipient. You do Everyone else, take note!

An excellent presentation. Better than anything on television! Dr. Bassler reminds me of a friend of mind who has a Phd in soil sciences: his enthusiasm is boundless and he makes dirt so very interesting. Question about inter-communication: do bacteria communicate with other bacteria to slow down or speed up their reproductive cycle? I can imagine scenarios where this could happen. But does it? Finally, we once again see that nature invented it first: networking, social media, and majority rule.

Such a great lecture. I hope millions of people see this. When Pasteur invented the method of cooking milk to prevent bacteria, he started the world on a road that classified bacteria as all bad, and this lecture i hope will start to turn that back around. We see more and more probiotic products sold, and i think over time people will realize that this quorum stuff is "the" important thing, because many bacteria are opportunistic, and sense which way things are going, and so keeping balance and not having them all pounce on us is very important for health. At some point the human body becomes a computer programming problem to study. I am sure that once you have 10 signals you are basically dealing with cellular algorithms. In a cell with only 2 types of sensors that is a pretty simple organism, but what happens when where are 10 inputs. That means 2^10 behaviors, which is 1024. It will be fascinating to see how many sensors they find. And i am still waiting for them to find the "chi" that the chinese talk about so much, the invisible energy that organisms possess, and can be projected from one person to another. That isn't chemical but some kind of radio, so there is another electromagnetic aspect of the cells that hasn't been discovered yet.

How this may well produce a beneficial therapy is many of the bacteria in your gut are not "good" or "bad", but rather they behave beneficially in under favorable gut conditions and detrimentally under unfavorable gut conditions. And often, Bacteria will be doing both beneficial and detrimental things at the same time, just to different extents. Many existing therapies tend to nullify all or all of a group of bacteria during treatment. This is why after treating some gut / systemic infections, patient need a transplant of good gut bacteria. There is a saying in biology...You can never do just one thing. Biology tends to be very highly interconnected; do one little thing, and it will likely cause multiple other things. A therapy that results from this experimentation may be able to halt precisely the detrimental actions of a particular group of bacteria without interfering with the beneficial actions.

This is one explanation for cancer and vindicates the theories from the early 1900s that stated that cancer is ultimately the condition of cells that should be communicating ceasing do so. As a result, they lose track of the fact they belong to a collective, and behave individualistically, growing a new colony and essentially a new organ. Luckily, if our immune systems are well fed and our inflammation reduced or eliminated so that signals can get through all layers of tissue, most of the time, our brain in coordination with our good cells prevent any wayward rebels from making it far, using the collection of phytochemicals they have collected from our diet, as well as the tricks they have learned from previous infections. If this system breaks down, we can develop allergies by attacking stuff that we shouldn't due to false associations in the immune system, and then inflammation, and then cancer. That was considered a fringe theory for almost an entire century, but now science mainstream is shifting towards it recently.

maybe English isn't her native language, but she misuses "shadow", she means "silhouette". The squid uses counter-illumination, to hide it's silhouette when predators look up towards it's body, so the squid lights the bottom of itself to match the moonlight, and starlight behind it. en.wikipedia.org/wiki/Counter-illumination FTA: "Marine animals of the mesopelagic (mid-water) zone tend to appear dark against the bright water surface when seen from below. They can camouflage themselves, often from predators but also from their prey, by producing light with bioluminescent photophores on their downward-facing surfaces, reducing the contrast of their silhouettes against the background. " link.springer.com/article/10.1007/s00227-003-1285-3 FTA: "Prior hypotheses have assumed that sepiolid squids in general utilize the bioluminescence produced by their V. fischeri symbionts for counterillumination, a behavior that helps squid camouflage themselves by matching down-welling moonlight via silhouette reduction."

Leaving aside the debunked "10 to 1" claim... that intra-species chemical is curious as they're way too similar to be coincidental... looks like it could be a driving force for speciation.... once a bacteria splits with a mutation on the gene producing the chemical, it becomes "cut off" from the rest of the group, causing it to begin a new group which will behave differently, and thus, react to future evolutionary pressures differently, driving a widening in the original genomes from the point of the original split with the mutation. Although I guess there would have to be some overlap if that were the case, where the receptor gene is duplicated allowing for a mutation on that gene first, so when the chemical producing gene is mutated, it already has a receptor for it... then gradually, it would lose the gene for the pre-mutation receptor... or something!

Great subject, but I see some major mistakes. The theme, of the mistakes, is something like an interest in making progress, having understanding, causing us to underestimate complexity, like "aha! the earth is flat!". Start with this question and a reason for that question: 1) why are you so certain that a "cell" is a meaningful term, and what exactly is a cell that our body is not a "cell" and 2) (reason for question) look at your language when you say "the bacteria recieves and enzyme and "knows" to turn on and turn off genes ))))....... in other words, great work, yes bacteria communicate, but look deeper into the _scope_ of _what you do not know_ then you well see a bit better what a "bacteria" really is, which is much, much more than what you call a "cell"

To me, it feels wrong to be seeking applications of this new knowledge to benefit our species, too early. This is a requirement imposed by for-profit capitalism. It is amazing that bacteria have developed quorum sensing so they can exist alone or in groups. How would they even "know" groups exist? How could they formulate tasks that benefit other life forms or how they could help create symbiotic relationships? And the more questions we ask, the more new questions are generated.

Question: From an evolutionary perspective, wouldn't it be more advantageous for a bacteria to develop the ability to "read" the environment for the universal communications molecule, but not create autoinducer 2 themselves? This way they could remain a silent "spy", able to read the environment for other bacteria, able to compare the ratio of autoinducer 2 to autoinducer 1, but without tipping off other species of their presence? Any bacteria that could mask their presence to other species would presumably have an advantage.
