...meantime, Eggan's group has provided an alternative method for generating customized stem cells that would take advantage of the early-stage embryos frozen in IVF centers around the country. The most reliable way of generating patient-specific stem cells remains nuclear transfer-taking the nucleus from a patient's skin cell and inserting it into an egg that has had its nucleus removed. This hybrid then begins to divide, and within a few days, generates stem cells that are genetically identical to the patient. The problem, however, as Eggan puts it, is that "there are never any extra unfertilized...
Eggan's group has found, astonishingly, that one-celled zygotes, or fertilized embryos that are on the verge of making their first cell division, can act just like the emptied-out egg in the nuclear transfer process. And because more of these zygotes are available than eggs, it may give patients another way of obtaining customized stem cells. In fact, notes Eggan, there may be even more such zygotes available if you count the abnormally fertilized embryos that IVF clinicians discard immediately. Anywhere from 3% to 10% of IVF embryos get either too many or too few chromosomes when they...
...biggest obstacle comes from Moscow, where President Vladimir Putin told reporters this week that Russia might again target countries in Europe that accept such a system. "If a part of the strategic nuclear potential of the United States appears in Europe and, in the opinion of our military specialists, will threaten us, then we will have to take appropriate steps in response," Putin said in comments released Monday by the Kremlin. "What kind of steps? We will have to have new targets in Europe...
...more than five years away. Yet if that should reassure Putin, it hasn't. He and the Russians see the deployment as both a potential future threat to their missile arsenal and as an affront to their national security akin to the American view of Khrushchev's deployment of nuclear missiles in Cuba in the early 1960s. So if the systems, which aren't even ready yet, are causing so much agitation in Russia, why is the Administration pushing as hard as it is on the issue...
...Robert Oppenheimer ’25, the father of the nuclear bomb, is invited to give the William James lectures. Entitled “A Hope of Order,” the lectures centered on the responsibility of science in the atomic age. Some students and alumni questioned the appointment of Oppenheimer because of his alleged communist ties...
