Experiment: Can Electromagnetic....

Postby seta37 » Fri Apr 24, 2009 4:10 pm

Can Electromagnetic Fields Be Used to Attenuate or Kill Bacteria?

I'm a new guy here (obviously) and I've had a lifelong obsession with biology and genetics. I've done lots of research and I've found a couple of things which support the idea I would like to test.

1) Malaria can be treated at least partially with electromagnetic fields
http://www.washington.edu/newsroom/news ... 33000.html

2) Sperm motility and regularity can be damaged by electromagnetic fields (cell phones)
http://www.cnn.com/2008/HEALTH/conditio ... one.sperm/


Hypothesis:
Alternative electromagnetic fields, by some mechanism, can harm the viability or vitality of bacteria

Experiment:
Control Group:
Bacteria sample on petri dish, isolated from electromagnetic radiation.

Test Group 1:
Bacteria sample on petri dish, exposed to constant magnetic pulses at about 1 Hz

Test Group 2:
Bacteria sample on petri dish, exposed to constant magnetic energy at about 700 MHz (frequency of cell phones)

Abstract:
If my hypothesis proves to be correct, then I should expect to see less bacteria (or none at all) in one or both of the test dishes. Of course malaria and sperm are not bacteria, however the news articles that I linked indicate that it is possible for EM radiation to do damage to single-celled entities, providing proof of concept.

There are a couple of possible mechanisms by which EM radiation can have detrimental effects on cellular life. In the case of malaria, it is theorized that the heme stacks tend to "spin" or rotate in response to a changing magnetic field, and perhaps this motion damages the internal apparatus of the cell. In the case of the sperm/cell phone - it is possible that the radiation from the cell phone acts as sort of a "microwave". Any polar molecule will "wiggle" or try to align with magnetic fields. This is how microwaves work. Perhaps the radiation from a cell phone affects particular compounds inside of sperm which has detrimental effects on it's vitality. If this is the case, then it is entirely possible that cell phone radiation would have similar effects on bacteria.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Any suggestions? Has this already been done? I googled it but I didn't find anything immediately relevant to magnetic fields affecting bacteria.

umm cell phones are very weak, fyi.

"umm cell phones are very weak, fyi."

Yes I realize - between 1 and 2 watts when active. This doesn't alter the fact that they are capable of damaging sperm.

advice: if you wanna be taken seriously don't cite CNN, cite some actual research journals.

Information is information, regardless of where it came from as long as it can be verified. CNN didn't produce the study they just reported on it.

And anyways, it's still proof of concept. I intend to do research myself.

Any advice relating directly to the practicality and methods I have proposed?

Reporters are notoriously bad at reporting science, read the original study, don't quote CNN.

Please do a background review and maybe some back of the envelope calculations if applicable.

The researchers didn't ask the men about other potential sources of electromagnetic wave exposure, like laptop computers, or where the men usually kept the phone when they talked. Next to their ear? In a pocket while using a headset? Says Agarwal: "There are hundreds of variables that can affect our conclusions."


USA today interviewed one of the researchers of a 2008 paper. Usually Ithink most reporters do fluff pieces, but this is a rare example of a good question being asked.

I have not been able to find any studies specifically measuring the effects of EM radiation isolated against the health of bacteria. Which is why I'm doing this study. The validity or accuracy of the CNN article is hardly relevant at this point.

What do you mean "background review ... back of the envelope calculations"?

I don't have any data to review or calculate yet...

Further support for simple uses of electricity to kill bacteria. Theoretically, if you apply a little bit of power to your skin, and enough of that current gets to your blood, it will do the same thing.
