...blue and white flag flying from University Hall announces, the Harvard Model United Nations (U.N.) began Thursday with nearly 1000 college students from 85 colleges participating in the four-day event...
Thomas McMahon, McKay Professor of Applied Engineering and author of McKay's Bees, and his research assistant Peter Greene specialize in biomechanics, a newly invented scientific method which unites biology and engineering. Constructing synthetic models of limbs, eyes and other body parts, the pair attempt to solve medical problems by discovering, simply, what went wrong in the mechanics. They have already made headlines for their peculiar specialty: in 1977, they experimented with artificial legs to discover the ideal running ground and came up with the celebrated new track for Harvard's Indoor Tennis and Track Building. The track has both...
...McMahon and Greene set to work building a mechanical eye. The model immediately provided two insights. First, strain occurs when the two oblique muscles--the muscles in the back of the eye which control its rotation--are tensed greatly, as in reading. The tension stretches and strains the sclera. Though such stretching is normally elastic, if it is both frequent and extreme enough the sclera does not return to its normal position and myopia develops. Second, the eye is least able to reduce strain near the point where the optic nerve enters the eye--Greene draws an analogy with...
...biomechanical model shows that myopia is both acquired and inherited. Excessive stress may explain how it is acquired, while location of the oblique muscles explains how it may be inherited. If someone is born with their oblique muscles attached near the optic nerve, they are more prone to myopia than most individuals...
Kopelev served as the model for the kindly Communist character Lev Rubin in Alexander Solzhenitsyn's novel The First Circle. After Stalin's death, all charges were lifted against Kopelev. Last week, however, Kopelev packed himself a small suitcase in readiness for yet another possible trip to the Gulag...
