Comments on: Could Bacteria Communicate by Bouncing Electrons Around Their Chromosomes?

I have been studying microbiology for a long time for personal interests. A few years ago, I believed that bacteria were able to communicate with each other in the environment and inside of us. I realize this is in its early stages of learning their secrets but in time I believe that science will learn that our own microbial biota has a direct impact on evolutionary changes over time.

Afterall, their survival is dependent on the reproduction success of all species too. They do not like unwanted pathogens on their turf anymore than we like getting sick from them.

Did this by any chance appear on April first?

… one bacteria says to other bacteria, right next to him:”Revolution!”

Look up Endosymbiotic Theory! It is VALID science for those who don’t follow Star Wars symbolism.

I still believe in the Midichlorians of Star Wars. Now put that in your pipe and smoke it! The implications are enormous! And it’s not as far fetched as spooky action at a distance.

So why not set up an experiment whereby a colony of bacteria is partially attacked by some kind of slow working poison or pathogen or something and measure the change in radio activity. Do it many more times using different strength and type of bacti killers etc., etc., etc., eventually there will be a pattern or no pattern and the basic question would be answered, deliberate or not?
Just out of perversity, save a few bacti from each onslaught and breed them, see if they learn.

From the paper, it looks to me like they’re modelling electron motion around a perfectly circular and static DNA loop as if it were a circular wire. How does this still work when basic biochemical processes like transcription, DNA repair and DNA replication are considered? Bacterial chromosomes are pretty dynamic places – they’re densely coated with proteins, melted for transcription, they are continually broken and rejoined during replication and usually accommodate multiple replication forks. Undergraduate texts might show them as “perfect circles” but in real life that’s just not the case. The paper presents no experimental evidence and the Montaigner papers were pretty thin (to be charitable) as well. The math might work, but the basis here is pretty lame…

1)There is a multitude of opportunities of discovering …but do we have the instruments to measure it?
2)All this can be related to the popular believe of long distance interaction between living beans, is there an opportunity to seriously study this?
3)If we are only 10%, how are the coordination and communication of all cells?

@John Lerch, that’s a great point–mito DNA is circular. Presumably the same phenomenon might be possible with human cells, then. I wonder if anyone’s copped a listen?

I wonder why they forgot to mention that higher animals including humans also have loops, just not in our main DNA. Our mitochondria are also loops.
