...tend to think of information as a liquid; we talk about how it flows through conduits--wires and cables--or gathers in pools in hard drives. But wi-fi turns information into an all-encompassing vapor that seeps into places it has never been before, and it has added an extra dimension to sleepy old Spokane. Elise Robertson is a 10-year veteran of the city's police force. Her squad car has a full-fledged wireless PC in it--the guts of it are in her glove compartment--with a touch-screen monitor stuck on her dashboard...
...cinema-verit? movement, and traversed the globe for United Nations and National Geographic documentaries. DIED. FRED WHIPPLE, 97, rocket scientist whose "dirty snowball" theory made it easier to track comets; in Cambridge, Massachusetts. Before Whipple explained the phenomenon in 1950, astronomers thought comets were loose collections of dust and vapor held together by gravity. Whipple argued that the core of a comet consists of ice, ammonia, methane and carbon dioxide, and that its gossamer tail consists of particles that break off from the mass as it approaches the Sun. Over seven decades of work at Harvard University and the Smithsonian...
Working in the Lyman laboratory, the researchers used a technique known as electro-magnetically induced transparency, in which they fired a red laser light pulse into a sealed glass cylinder containing rubidium vapor. They fired two control beams through the vapor, rather than the one beam used in previous experiments, so that their interaction simulated the effect of tiny atomic mirrors...
...photons within the light pulse in the vapor bounced back and forth so that the light pulse as a whole was frozen in space...
...Overshadowed for weeks by the U.S. rover Spirit, Europe's Mars Express - which has been orbiting the Red Planet since Dec. 25 - finally got its day in the sun. As well as relaying stunning close-ups of Mars, the orbiter detected ice at its south pole and identified water vapor in its atmosphere. The findings reinforce the idea that Mars may have supported life...
