...temperature of certain metals and ceramics far enough (-459°F is a good number to shoot for), and they carry electromagnetic charges far more efficiently and for a far longer time than they otherwise would. When the metals are magnetized, they become so powerful that their ability to repel one another can actually allow them to lift heavy objects off the ground. That's the elegant principle behind some kinds of magnetically levitated (maglev) trains. (See the 50 best inventions...
Everything in the universe - metals, gases, dogs, doughnuts - is made of materials with positive and negative charges. Opposite charges attract each other; identical charges repel each other. What prevents us from sticking to anything with an opposite charge is that all these forces have to be properly aligned before you can see them at work. "The materials are in motion, but sometimes the dance of the charges allows them to fall in step," says NIH physicist Adrian Parsegian, one of the authors of the paper. "When that happens, you get attractive forces...
...AIDS. (Researchers have long known that about 1% of Europeans carry a genetic mutation that makes their cells resistant to HIV infection.) Bone marrow produces the cells that HIV attacks. So, the thinking went, inserting marrow that produces HIV-resistant cells might endow the patient with a means to repel the infection. Twenty months after the transplant, Huetter says, the man shows no signs of carrying the virus. (See stories of people surviving with...
...made more complex and obscure by a puckish dark-humored whimsicality. Collectively, these elements are fitting for a New Pornographers’ video. A.C. Newman’s power poppy voice can either draw you in and make you want to have your own weird little party or else repel you by being just a tad too chipper for an ordinary day. Either way, the video at least borders on entertaining. Fortunately for the play-acting band members, this party has a happy ending. “And here’s the mutiny I promised you / And here?...
...unions were driven out of Los Angeles. Compromise would be surrender. Rather than negotiate, he prepared for new battles. He now called himself "General." He christened his sprawling home "The Bivouac." He mounted a cannon on the hood of his limousine and made sure his chauffeur was prepared to repel, at his command, any enemy attacks. He modeled the paper's new printing plant on a fanciful vision of an impregnable fortress, complete with battlements, sentry boxes, and firing holes offering protected lines of fire at any mob that dared to storm his citadel...
