...days later, again in the Sterling's main reading room with several books destroyed in the flood resting in front of him, Yale President Richard C. Levin announced a $48 million plan to renovate Sterling, $35 million of which was to go for protecting the collection from heat, humidity, ultraviolet light and air pollution...
...worried," says David Hoppe, a University of Minnesota herpetologist. "We don't know how far this is going to go." Because frogs spend much of their life in water, pesticides or toxic metals were prime suspects. But now possible causes include acid rain, global warming and increased ultraviolet light. Hoppe observes that different deformities seem to be concentrated in frogs from different regions. It may be, he says, that more than one cause is at work...
...same synergies that empower microbes also weaken our defenses against them. Heat, increased ultraviolet radiation resulting from ozone depletion, and pollutants like chlorinated hydrocarbons all suppress the disease-battling immune systems--both for humans and for other animals. Epstein, who is one of the principal authors of the upcoming WHO study, notes that in recent years variants of the class of viruses that includes measles have killed seals in the North Sea, lions in the Serengeti and horses in Australia--three very different animals widely scattered around the globe...
Charities covered P.J.'s medical expenses, but local residents chipped in to build a special playroom that blocks out ultraviolet rays and filled it with every toy imaginable. While the room was being built, a young carpenter came to help lay the concrete floor. "He kept sanding and sanding and asking us what kind of finish we wanted," Deloris recalls. "The two carpenters with him told him that it was fine like it was because all we were going to do was put carpeting down." After the carpenters had gone, Deloris looked outside, and the man was still there, sanding...
...bring them down to earth, to imagine them rising on the horizon or just beyond the wings of an airliner. These are no ordinary clouds, however. They stand not 30,000 ft. but almost 6 trillion miles high. They are illuminated not with ordinary earthly light but with searing ultraviolet radiation spewing from nuclear fires at the center of a handful of newly formed stars. And they're 7,000 light-years from Earth--more than 400 million times as far away...
