Last year a new genetic engineering technology called CRISPR - Clustered Regularly Interspaced Short Palindromic Repeats - showed up on my radar at a local conference. Long story short, CRISPR is a highly precise technique for editing DNA in situ which follows from the discovery of short sequences of DNA which allow for precise location of individual genes. It's a fascinating technology; there are even tutorials (archived copy, just in case) online for developing your own guide RNA to implement CRISPR/Cas9. What you might not have known is that CRISPR/Cas9 is being actively studied as a theraputic technique in humans …

In the year 2007 an HIV-positive American citizen named Timothy Ray Brown, who resides in Berlin, Germany underwent a stem cell transplant after being diagnosed with a particularly nasty form of cancer called acude myeloid leukemia. AML is a sufficiently specific syndrome that there are a couple of good treatment protocols for it, among them a stem cell transplant to replace the malfunctioning cells in the patient's bone marrow which manufacture defective blood cells. Now, here's where it gets interesting: the donor of the stem cells had a very specific genetic mutation which results in cells of the individual's immune …

Have insurance companies sunk to new lows?

  aids hiv insurance medication profit rape risk treatment wtf

As you may or may not be aware, insurance companies have some pretty manichean arbitrary criteria to decide whether or not a particular procedure, treatment, or medication are covered, or to what extent. To give you an idea of how they operate, I discovered the hard way a few months ago that my insurance company (no names or they'll probably turn around and drop Lyssa and I like a bad habit, knowing those fuckers) informed me that a particular treatment "should not" cost $190us, but "should," in fact, only cost $71us. They then informed me that they would pay only …
