| Microcyn == Super oxidized water | (2005/05/24 22:00) |
This Wired article on Microcyn dumbs down the essentials, but does describe a really interesting breakthrough in wound treatment. Basically this pH neutral oxidized water made by Oculusis is able to treat wounds more effectively than antibiotics and seems to be the only functional treatment for certain types of diabetic ulcers. |

| New method for generating stem cells | (2005/05/24 16:30) |
Wired reports on a South Korean team's method of generating custom stem cells. This technique uses embryonic stem cells to generate a custom line that is a genetic match to the patient. This reduces the chance of immune rejection. More and more, these inventions are going to be happening outside of North America and Europe due to stupid policies around research. I'm extremely glad to see that countries like China and South Korea are are generating these results, but I feel sorry for researchers trapped in the US. I hear that China's offering some really stellar packages for top geneticists who are willing to relocate. |

| DNA Hack Website | (2005/05/19 08:50) |
DNAHack.com has a pile of articles and references for the amateur bio geek. From basic DNA extraction to protocols for preparation of slides, this is looking like a really cool site. |

| Simple low tech DNA extraction | (2005/02/14 08:30) |
I was at CodeCon over the weekend and one of the presentations was on SciTools which is a rad web based platform for doing genetics work. (More on that in a few posts). Meredith L. Patterson started the presentation off by demonstrating DNA extraction using household items. Here's the procedure: - grind up the material if it's a solid - add water and some salt - add shampoo (for the sodium laurel sulphate) which breaks down the cell walls - stir and then drain out some of the liquid to a new container - add meat tenderizer or contact solution - centrifuge (with a salad mixer) - add rubbing alcohol - waitAfter that's done, you'll wind up with a layer of DNA, floating above the water. The really cool part of the talk demonstrated the discovery of RNA sequences to build a knockout sequence for a common breast cancer. More on that when I either reconstruct the sequence from notes or they post the presentations. |
