...biology experiments conducted by the Viking landers. The gas exchange test, based on the fact that terrestrial organisms give off gases as waste products, involved dropping a pinch of Martian soil into a warm, moist test chamber. The aim was to determine whether the sample would give off carbon dioxide, as animals would, or oxygen, as plants do. Scientists were surprised when the sample began releasing oxygen far more rapidly than plants would be expected to do. But they noted that the reaction might have a purely chemical, rather than a biological explanation; compounds called peroxides could have released...
...citizens at Eagle Point, Ore., [Dec. 20] presents a cogent case against local control of school systems. The right to a decent education is simply too important to be subject to the caprices of community conservatism and ignorance. Do these parents want to turn their young people into carbon copies of themselves? Gene Wright Madison...
...stage that follows is short-lived. Its fires banked, the star is deprived of the outward radiation pressure. It contracts violently, driving the core temperature up again, until it reaches 200 million degrees. That is hot enough to ignite the helium, which fuses into a still heavier element: carbon. Its radiation energy restored, the star zooms back toward red-giant status 100 times faster than it took to get there the first time...
...Technology and the Lincoln Laboratory used a radio telescope to discover the hydroxyl radical (two-thirds of the water molecule) in space. Since then, more than three dozen molecules have been found floating in the galactic clouds, including those of methane, formaldehyde, ammonia, hydrogen cyanide, ethyl alcohol and carbon monoxide...
...momentous discovery within his grasp. For obviously what the student had unwittingly stumbled upon was a fair copy of a previously unknown fragment of Paradise Lost. I of course did not jump to this conclusion, but subjected the fragment to all possible tests, including metrical analysis and carbon 14 dating, before deciding that these lines are indeed by Milton. Possibly they represent an abortive attempt at a Book XIII, or even the beginning of a sequel to Paradise Lost. However, the regularity of the iambic pentameter suggests that these lines were written early in Milton's career, and hence represent...
