...astronauts who have just returned to earth. The bed rest was also followed by placing the women in a centrifuge and whirling them at three Gs for as long as they could endure it; that simulated reentry. They also rode bicycle trainers as long as possible to determine their oxygen intake. The results of the tests have shown NASA that women can make space flights. Encouraged by this success, the doctors plan to broaden their program to include prospective passengers 40 to 60 years...
...hapless diner is suddenly unable to breathe, talk or cough. A panicky struggle may ensue, as he tears at the lower throat or upper chest. He quickly becomes blue in the face and collapses to the floor or into his plate. Without proper help, death-from lack of oxygen-occurs in four or five minutes...
Those who fear fainting spells might like the necklace that contains a small oxygen mask. Another necklace, this one trimmed with peacock feathers, monitors the wearer's body temperature. An ornate gold and silver bracelet carries an electronic gadget that measures pulse rate. Perhaps the farthest-fetched item is an enclosed vehicle, with "legs" in back and wheels in front. It carries one rider and is powered by a small motor. Called the Madison Park Stroller, it is supposed to be a piece of art as well as a conveyance...
...Stanek babies were large for sextuplets. They ranged in weight from just under 3 Ibs. to 3 Ibs. 10 oz. Doctors placed them in incubators, and gave four of them extra oxygen to breathe. Even so, their underdeveloped lungs quickly encountered the same respiratory problems that account for half of all deaths among premature babies. The weakest of the six, a girl the Staneks had named Julia, died of hyaline membrane disease, a disorder of the inner lining of the lungs, 44 hours after birth...
...highest expectations did not prepare University of Chicago Scientists Robert Clayton, Lawrence Grossman and Toshiko K. Mayeda for what they discovered while studying fragments of the Allende meteorite, found near Pueblito de Allende in Mexico in 1969. Tiny grains of dust imbedded in the chips contained an isotope of oxygen (oxygen 16) in virtually pure form. Ordinary oxygen in the earth's atmosphere−and presumably that on the sun and other members of the solar system−also consists mostly of O16. But it also contains small amounts of other isotopes−oxygen 17 and 18, which were...
