Bonnie Bassler: The secret, social lives of bacteria
http://www.ted.com Bonnie Bassler discovered that bacteria “talk” to each other, using a chemical language that lets them coordinate defense and mount attacks. The find has stunning implications for medicine, industry — and our understanding of ourselves.

wow fabulous …
wow fabulous speaker and great discoverys thankyou for this interesting video …i guess though like anything this could be used against as a biological weapon ,,or if the world powers decided to depopulate as intercellular comunication could be blocked in humans etc etc …lets hope its used for good

Make the bacteria attack early by injecting a higher does of that signal chem so they get curb stomped by your immune system.
Now!
Wheres my Nobel.

The only reason a …
The only reason a bacteria can make us sick is by making toxins… without the toxins our immune systems will kill them.
We could in time make microbial hunter killer that attack the bacteria strains that causes us illness based on the specific transmitters they produce.

There isn’t much of …
There isn’t much of a competing answer other then quantum interactions to explain how microbes can process up to 100,000,000 bit’s per second with a nanobrain composed of proteins and a bundle of around 10,000 microtubules.
clearly microbes are the most intelligent organisms on earth, at least on a per gram weight basis.
Also we are moving closer to making neuralnets out of bacteria.

there horizontal evolution lets them evolve way faster then us… for us evolution is survival of the fittest and for them it’s a mass produced horizontal evolution via plasmids.

Nah, I wasn’t right …
Nah, I wasn’t right at all. They used Cholera bacteria for their virulence test which actually turns off it’s toxic behavior at high density, this way they tricked the bacteria into thinking there was more of them than there was, and they turned themselves off. Still an amazingly cool concept.

…continued, sorry …
…continued, sorry. She did mention that her synthetic molecules somehow ‘jam’ the sensors on the cell, and I suspect would produce false positives. When enough of the synthetic molecules are jamed in the bacteria, it would activate it’s virulent behavior before reaching that threshold number of bacteria to be harmful, provoke your immune system and be destroyed without much of a fuss.
Anyway, I’m off to find out…

We didn’t get to …
We didn’t get to learn enough about how bacteria actually count these molecules to what exactly her treatment in mice does.
I imagine the bacteria have many sensors along their cell membrane and basically get a, Yes (there is a molecule in this sensor) or No (there is no molecule in this sensor) response from each sensor. Once it receives a threshold level of simultaneous Yes’s, it activates a behavior. As opposed to somehow having a memory of how frequently is counts one of these molecules.

Not really. She specified two types of blocking mechanisms - specific, and general. My question was directed toward the general blocker.

You missed something.
She said blockage for “specific” bacteria or viruses.
