...Boston marathon tends to draw out a vein of exhibitionism in runners. Why elso would someone sweat out the course in a full tuxedo as one runner did Monday? "It's like the race is a parade and the runners are floats, only better," one runner said. Another hint for you prospectives: wear something catchy so the crowd will yell for you it can carry you through the race. Try, for example, a totem pole mask and a flowing blond wig, like one Japanese runner did this year...
Harvard paleontologist Elso S. Barghoorn liberated a prehistoric algae from the rock prison it had been locked in for the past 3.5 billion years. The freed algae had no immediate words for the press, although Barghoon claims it is the oldest form of life anyone has ever seen...
Then how and when did free oxygen begin appearing in the atmosphere? A clue to the answer has been found in the incredibly old sedimentary rocks of South Africa's eastern Transvaal by Harvard's Elso Barghoorn and Andrew Knoll, now with the Oberlin College department of geology. To the naked eye, the 3.5 billion-year-old rocks Barghoorn and Knoll collected during a visit last year revealed no traces of early life. But the scientists soon uncovered the stones' secrets. Returning to Harvard with samples of the rock, the pair used a diamond cutter...
...Elso S. Barghoorn, Fisher Professor of Natural History and a member of the exobiology panel of the American Academy of Science's Space Sciences Board that was established in 1958 to advise NASA, said yesterday, it is "certainly an inorganic reaction" which is causing the release of oxygen...
When did life begin on earth? Harvard Paleobotanist Elso S. Barghoorn and his onetime student, J. William Schopf, discovered a possible answer to that intriguing question several years ago, when they found microscopic fossils in ancient South African rocks. These tiny traces of life indicated that single-celled creatures existed as long as 3.1 billion years ago. Now a team headed by Schopf himself has found evidence that could push the dawn of life back at least another 200 million years...
