Many questions remain. For one thing, researchers are worried that gamma secretase may perform vital functions in the brain and that blocking it could cause serious side effects. Also, no one knows whether strategies aimed at lowering levels of beta amyloid will have any impact on the course of Alzheimer's disease--though if the beta-amyloid hypothesis is right, they should. Selkoe and other Amyloid People now see the disease process as a biochemical cascade; the event that triggers the cascade, they believe, is the accumulation of beta amyloid...
Cousin also has a love of music, shown through his work this summer for MINHUET, a public service program through which Harvard students perform at area hospitals and nursing homes...
There is hardly a religious group in America that is not beset by the issue that rent the Methodist meeting in May: the place of gay people in its pews. In March the organization of Reform Jewish rabbis agreed that its members could perform gay-holy-union ceremonies if they chose. The group was then castigated for it by other Jewish branches. Last month the Vatican, which had earlier ordered an American nun and priest to end a ministry to gays and their families because it did not stress the "intrinsically disordered" nature of homosexuality, further prohibited...
...stakes have risen, so has the pressure to perform--and the frustration among parents, students and educators. In the past year, protest-the-test groups have sprouted in at least 36 states. In Colorado, more than a thousand parents, teachers and students surrounded the state capitol in March and demanded that Governor Bill Owens take the test. (He too declined.) Parents in Louisiana, Indiana and California have gone a step further, filing lawsuits alleging that the tests violate their children's civil rights. In Illinois, 200 students claimed they flunked the test on purpose. Teachers are taking to the streets...
...that a quantum supercomputer is going to leap out of some laboratory and paralyze the CIA anytime soon. These computers seem to be exquisitely sensitive. The tiniest disturbance--even a passing cosmic ray--can change the orientation of their computational atoms, spoiling the calculation. At present, quantum computers can perform only trivial calculations on perhaps five atoms. To do any useful work, they would need to calculate on millions of atoms...
