P.U.F.F.#5, Stool Stories

Disgusting diseases, dismal odors, and dank messes are how most of us view human waste. However those clever scientists sure know how to make ‘stone soup’ from fertilizer!

So, let me set up the problem. In America only about 3 in 100 actually donate blood. And every 2 seconds, someone needs blood. And the wrong kind of blood given to you can kill you. So you need all these different types of blood in stock, all over the country.

This is obviously next to impossible, and there are always shortages of one type or the other. There is a universal blood type (O-), that can be given to anybody, but only 7% of US population has this type. So scientists would love to be able to ‘create’ more type O- blood.

And, through clever enzymatic reaction of bacteria DNA harvested from human stool the scientists have done just that! They are able to convert type A blood to type O-. They basically use an enzyme from this bacterial DNA (cultured in E. coli medium) to strip off the ‘type A’ from the surface of the whole blood cells, leaving them type O blood.

Really fascinating work, but still 2–5 years away from widespread use. Worth the read. Don’t miss the abstract at the end, which though a bit sciencey, is fabulously worded.
