...doesn't officially begin at Greenwich, but don't tell that to anyone in Britain. The London borough, home to the Royal Observatory and located right smack on the 0[degree] meridian, will mark the stroke of midnight, Greenwich mean time, by shooting a green laser beam into the sky and bouncing a satellite signal around the world that will set off international celebrations...
...toast. The locally renowned "low-tech magic" performers, Public Dreams Society, are coordinating with other community groups to design an interactive spectacle featuring live music and stilt dancers, whose costumes will literally burst into flames. There will be a black-tie gala, at least two fireworks displays and a laser light show. And to ensure that no one goes hungry, food will be served to the needy on the downtown east side. Throughout the day, all 23 of the city's community centers will offer free family events...
...been used for more than a decade to select the sex of cows, horses and pigs. Working with U.S. Department of Agriculture scientist Lawrence Johnson, who invented the method, they stained sperm with a fluorescent dye that latches onto DNA. Measuring the glow of the sperm cells under laser light, they could gauge how much genetic material each one carried. As it happens, X chromosomes have about 2.8% more DNA than Ys. Once the sperm had been distinguished this way, an automated sorting machine separated the Xs from the Ys, and doctors could perform artificial insemination...
...Horowitz, who declined to comment and referred all questions to Leigh when reached by telephone last week, is beginning an "optical SETI program" to "look for very short pulses of laser light...
...technique perfected by the not-for-profit Genetics & IVF Institute involves staining sperm cells with a DNA-sensitive fluorescent dye and then passing them single file through a laser beam. The cells are sorted based on the amount of light reflected by the fluorescent DNA. It's painstaking work -- sorting a single batch takes the better part of a day -- but the results speak for themselves: Of 14 pregnancies produced so far for couples who wanted a girl, 13 fetuses were female. Not entirely foolproof, but pretty close...
