Famed Chemist Urey (Nobel Prize, 1934) proved three years ago that certain fossil sea shells can be used as fossil thermometers to measure "paleotemperatures." His method takes advantage of the fact that normal oxygen contains two stable isotopes, oxygen 18 and oxygen 16, in the proportion of 1 to 500. When a sea mollusk takes up calcium carbonate (CaCO3) to build its shell, the proportions of the oxygen isotopes in it vary with the temperature of the sea water. The warmer the water the less oxygen 18 is built into the shell...
...measuring the percentage of oxygen 18 in fossils, Urey showed that the seas around Britain, now cold, could have been as warm in Cretaceous times as tropical seas are today. This indicates that the whole earth was warm at that time, and therefore fine for furless, cold-blooded dinosaurs. Urey's next job will be to measure the temperature of the Eocene period that followed the Cretaceous...
...Antonio last week, two businessmen installed a slot machine which advertised a hangover remedy for 25?. The remedy: a 30-second sniff of pure oxygen (which some people believe will mitigate hangovers), taken through a cone which the user holds to his nose...
...plateaus. A Norwegian Air Force Catalina flying boat patrolling near Spitzbergen gave him a radio call as he whisked past, reported back that Captain Blair was right on course. Hour after hour, the Mustang bored through the blue-grey sunlit haze over the icecap. Blair sat hunched behind his oxygen mask occasionally shooting the sun with a sextant...
...faint radio signals from a radio range came in over his set. Blair homed in on them, crossed Alaska's northern coastline just one minute off his schedule. He refueled near Fairbanks, roared east at 25,000 feet across Canada, munching a roast beef sandwich between gulps of oxygen. Nine hours later, he set his Mustang down on the runway at New York's Idlewild airport. He was the first man ever to fly solo across the hazardous North Pole route in a single-engined plane...
