...year-old evangelist sits on a pink couch in an Orlando condo with a view of a lovely little lake, oxygen feeding constantly through a tube in his nose. He is not in good shape: incurable pulmonary fibrosis has left him only 40% use of his lungs, and his doctors told him a year ago that he had just months to live. But with the inexorable will that has made him an empire builder, he pumps his latest project, a swashbuckling novel featuring a miracle-working naif who brings God's word from Ethiopia to California. Bill Bright...
...These schools compete for students like L.J. Decker, 17, from Katy, Texas, who scored 1560 on the SAT and was part of a team of home schoolers who won the Toshiba ExploraVision contest for their idea of a futuristic scuba device that would use artificial hemoglobin to convert the oxygen in water into...
...basis for a complex marine food chain was in place 1.5 billion years ago, yet for some reason never got past the square marked GO. Why not? The hypothesis Knoll favors invokes the competition between two classes of compounds for control of the biochemical environment, one based on oxygen and the other on sulfide. During most of the Proterozoic, it turns out, only the shallows were infused with oxygen. The deep oceans, by contrast, were inordinately rich in sulfides, which indirectly interfere with the ability of algae to make use of growth-promoting nitrogen...
Just before the Cambrian, however, something big happened. The deep oceans were made oxygen rich and sulfide poor, Knoll believes, when an unusual spate of undersea landslides (triggered by the breakup of a primordial supercontinent) buried megatons of oxygen-consuming debris. Virtually simultaneously, microscopic algae spread far and wide. For the first time since the planet's formation 4 billion years earlier, the oceans were capable of supporting a population of small-, medium- and large-bodied animals...
...least that's the hope of investors who have lobbed the first of potentially billions of dollars at a simple chemical principle that an obscure British scientist named William Grove discovered in 1839: when hydrogen and oxygen molecules combine to form water, heat and electricity are produced. Tapping that energy, by binding individual cells into what is known as a "stack," could mean efficient, continuous and clean electricity for everything from long-lasting cell-phone batteries to industrial power generators. And although fuel cells have generated buzz at least since astronauts took a prototype into space on Gemini...
