Bohdan Pomahac, the associate director of Brigham and Women’s burn unit and the head of the hospital’s face transplant program, told the Globe that he has performed dozens of facial surgeries using skin grafted from elsewhere on the patient’s body, leaving the patient still looking disfigured...
Scadden said that this process of somatic nuclear transfer—essentially taking a nucleus from a skin cell, transferring it into an egg, and then prompting the egg to divide—would allow scientists “to have in a petri dish a model of these complex diseases for which we have very little therapy...
...doesn't. (No wonder he won't say how many of the 45 million uninsured his health-care tax cut would cover.) Note that this question lets Republicans embrace universal coverage without supporting a Canadian- or British-style single-payer system. Michael Moore aside, there are different ways to skin the cat here. Liberals should insist on Republicans who explicitly share their goal; how we get there can be negotiated...
...team, which included leading researchers from England, Japan and Canada, conducted a whole-genome analysis of the DNA from Hwang's stem cell line. By analyzing tens of thousands of gene snippets on the cells' genomes, and comparing these signatures to those of the egg donor and of the skin cell donor, they were able to determine that the DNA fingerprint of the stem cells was consistent with that of the egg. "The genetic signature of a parthenote is very very obvious," says Daley. Because the genetic material in parthenotes comes only from the egg, they are missing key genes...
Much more invasively, investigators are looking into deep-brain stimulation (DBS), in which electrodes are implanted in the brain and connected by wires embedded in the skin to a pacemaker-like device in the chest. Low doses of current can then be applied as needed to calm the turmoil in the regions of the brain that cause OCD. The procedure sounds extreme--and it is--but it's already been used in about 35,000 people worldwide to treat Parkinson's disease, and FDA approval to use DBS for OCD as well is pending. "Many of our OCD patients...
