...been higher 81,000 years ago than today is that the Earth was receiving stronger solar radiation at that time. That would fit into what's known as the Milankovitch theory of ice-age cycles, which posits that the Earth's orbit around the sun and the planet's axial tilt wobble periodically, increasing or decreasing the amount of solar radiation hitting the planet's surface. "The sea-level high may be considered an exception to the 100,000-year cycle, in which high summer sunlight caused the ice sheets to melt," writes R. Lawrence Edwards, a geologist...
...breakthrough that allowed for this new precision include a new technique to cool an electron until it reached its quantum-mechanical ground state, according to physics graduate student David A. Hanneke, who co-authored the paper. The researchers then carefully controlled the planar and axial motions of the electron through a combination of electric and magnetic forces to measure precisely the frequency responses of the electron...
...rather impersonal rooms. It is furnished with several comfortable armchairs, but the President slept on a standard metal hospital bed. Before dropping off, he was put through the battery of tests drearily familiar to anyone who has been prepared for major surgery: chest X ray, electrocardiogram and CAT (computerized axial tomography) scan, a kind of super X ray of a large portion of the body. The scan showed no sign of cancer outside the colon. The tests ended about 11 p.m.; Reagan then read for a while (what, no one would say) and fell asleep a bit after midnight...
DIED. SIR GODFREY HOUNSFIELD, 84, British electrical engineer who invented the C.T. scan, a diagnostic tool that revolutionized medical care; in London. In the 1960s he built the computerized axial tomography scanner, which uses X rays to give doctors a three-dimensional, cross-sectional view of the body's interior. The innovation brought him the 1979 Nobel Prize, which he shared with South African scientist Allan Cormack, who had worked independently on the idea...
