...genes are the first to be linked directly to MS since the 1970s, when researchers initially identified a cluster of DNA on chromosome 6 associated with immune system function. Doctors believe MS is an autoimmune disease, in which the body mistakenly attacks its own healthy cells. But they have never been able to figure out why the body turns on itself, and they hope these new genes may offer a clue. "This is by no means the final, whole answer, but we've gotten an incredible glimpse into the cause of the disease," says Dr. David Hafler, professor of neurology...
Hafler acknowledges that these findings are only the first step. Uncovering additional genes will require analyzing an even larger pool of MS patients and their families - Hafler is hoping to find at least 9,000 more patients. He calculates that with that much DNA, he'll be able to tease out 90% of the genetic culprits involved in MS. "These first genes give us a working hypothesis for what may be causing MS," says Hafler, "and a lot more work needs to be done. But we have finally begun...
...good mayor's ad hoc phrenology correct? Or was Schiller's fertile brain actually housed in another skull dug up almost a century later? Scientists from the Friedrich Schiller Code research project are now determined to find out. They will compare dna taken from the two skulls with dna from the skeleton of Schiller's second son, Ernst Friedrich Wilhelm, who was exhumed in Bonn on July 19. "Ultimately, this will show us whether one of the skulls is Schiller's - or whether neither of them is," says Freiburg anthropologist Ursula Wittwer-Backofen, one of the chief Code researchers...
...work with local authorities elsewhere to pursue terrorist suspects to all corners of the globe. To a greater extent than in the U.K., Americans involved in the case stand behind the conviction. "I am convinced of Mr. Megrahi's guilt," says Marquise. "It would have been great to have DNA, to have 10 eyewitnesses. Unfortunately, there's no such thing as a perfect case," An FBI spokesman in Washington says the Bureau will not comment on the SCCRC report as the matter is now pending in court...
...look at tumors for changes at the DNA, RNA and protein levels," says Dr. Gordon Mills, chair of systems biology at the M.D. Anderson Cancer Center in Houston. "It certainly gives us a way of looking at what is happening inside a tumor, and that's very exciting...
