I can't even be mad about getting Cotton Eye Joe stuck in my head because that was magical!

Is it sad that I am having sympathy for bacteria?

How the heck did this pass an Internal Review Board? Subjecting those poor specimens to Cotton Eyed Joe. :(

Magnetite from bacteria, in addition to being fucking awesome, has also lead to a wide array of very useful tools in molecular biology. Unlike the nanoparticles of magnetite that can be synthesized chemically (instructions available online*), they have a consistent size and shape as well as a membrane coating that can be made to stick to things with very specific interactions.
Application of magnetic techniques in the field of drug discovery and biomedicine
Magnetic separation technology, using magnetic particles, is quick and easy method for sensitive and reliable capture of specific proteins, genetic material and other biomolecules. The technique offers an advantage in terms of subjecting the analyte to very little mechanical stress compared to other methods. Secondly, these methods are non-laborious, cheap and often highly scalable. Moreover, techniques employing magnetism are more amenable to automation and miniaturization. Now that the human genome is sequenced and about 30,000 genes are annotated, the next step is to identify the function of these individual genes, carrying out genotyping studies for allelic variation and SNP analysis, ultimately leading to identification of novel drug targets. In this post-genomic era, technologies based on magnetic separation are becoming an integral part of todays biology laboratory. This article briefly reviews the selected applications of magnetic separation techniques in the field of biotechnology, biomedicine and drug discovery.
*If any of you guys do end up buying this, please don't fuck with it and be super careful around kids. I've been making ferrofluid for a while and nanoparticles of magnetite haven't really been meaningfully tested for long term safety. Consider using gloves and make sure it doesn't interact with food or anything that could get inside of you.

New York's hottest new club is called CROBE, it has everything, bacteria, line dancing, controllers, magnets...

Wait a minute... one of the tags is MassDeath? What is this? Heavy Metal? I thought I came in for country....

I noticed a few stray bacteria that either didn't move at all or simply continued on in the direction they were originally headed even when the scientists were moving the controller -- are those a different kind of bacteria that are not sensitive to the magnet? Or is there a certain percentage of magnetotactic bacteria that will always go their own way no matter what?

I want to be the Busby Berkeley of magetotactic bacteria.

The ones not line dancing were the bacteria that have evolved a sense of taste.

Bacteria, much like post-docs, are not considered human subjects.

Is this what we are paying you for? Go back to work and cure cancer!

Nah. Either Wallflowers, small children, or the elderly come to watch the young'uns having a good old time. Some of them old timers could really shake a tail a day or so ago.

Dancing is always better when you put your bacteria into it.

Blaseldb, magnetic separation technology is my life. SPRI for all! Could I train little flagellated magnetotactic bacteria to perform more precise separation for me? Carry my polyA RNA around in their little hands?
