...Wyler Children's Hospital, a part of the University of Chicago, an unnamed 2-1b. boy, born in the sixth month of pregnancy, is sustained with the help of something called a radiant warmer bed, plus a phototherapy unit, an infant ventilator, three volumetric infusion pumps, a transcutaneous oxygen monitor and a cardiac-respiratory monitor...

Ophthalmologists offer several possible explanations for the extended-wear problems. The lenses can be worn for weeks because they contain many more tiny pores than traditional soft lenses, allowing an increased supply of oxygen and water to reach and nourish the cornea. But the myriad pores encourage the buildup of deposits on the lenses, creating a perfect breeding ground for bacteria. The resulting infection spreads to the cornea and can cause partial or complete blindness in just 24 hours. Even if the problem is caught and treated early, Kenyon says, a scar often remains, interfering with vision...

Trouble may also occur because the lenses are worn at night. With eyes shut and lenses in place, says Doughman, the oxygen supply to the cornea may be reduced enough so that, in some cases, the corneal cells are damaged, thus making the eye vulnerable to attack by bacteria...

...instant later the tip of the booster pivoted into the external fuel tank. The ensuing explosion rocked but did not obliterate the shuttle. "The orbiter itself seemed to float, very briefly, above the fireball of exploding hydrogen and oxygen," said one member of the shuttle inquiry panel. He was reminded of the way a bubble survives a cascade over Niagara Falls, "so fragile, yet with all that wild energy around it." Says a National Transportation Safety Board investigator: "The crew compartment was pressurized and sealed tight and welded into a kind of cocoon or bubble that may have suffered relatively...

Although the Soviets did not reveal what caused the explosion, it was apparently the highly volatile liquid fuel of the SS-N-6's. The fuel is "some kind of propellant combined with liquid oxygen," says Lieut. General Richard Burpee, director for operations of the Joint Staff. "Those will ignite on contact with each other, so you have to keep them separate. Handling those two fuels in the same missile is not without its hazards." Because of the danger, liquid-fueled missiles are carried only on older Soviet subs like the Yankee I class, which went into service between...
