...bombarded with electromagnetic radiation -- in this case microwaves -- it shifts into a new energy state. Each type of atom responds most readily to a particular frequency. For the cesium-133 atoms in most atomic clocks, the frequency is 9,192,631,770 vibrations per second. When a microwave beam inside the clock is set to that frequency, the maximum number of atoms will undergo the energy switch, signaling the clock's internal computer that the device is correctly tuned. The vibrating microwaves keep time; the atoms just keep them on track...
...trial also proved to be a tricky test for the people who decide what mix of news CNN will beam to its global audience. As the network's impact has grown, those decisions have become more crucial. To the extent that the images CNN chooses to show -- Boris Yeltsin defying coup plotters or a reporter sifting through bomb damage in Baghdad -- are important in shaping people's attitudes and governments' policies, a handful of news executives in Atlanta are among the world's most influential journalists...
OPTICAL TWEEZERS. With a single beam of infrared laser light, scientists can seize and manipulate everything from DNA molecules to bacteria and yeast without harming them. Among other things, optical tweezers can keep a tiny organism swimming in place while scientists study its paddling flagella under a microscope. Optical tweezers can also reach right through cell membranes to grab specialized structures known as organelles and twirl them around. Currently, researchers are using the technology to measure the mechanical force exerted by a single molecule of myosin, one of the muscle proteins responsible for motion. Scientists are also examining the swimming...
...miracle is a wonder, a beam of supernatural power injected into history. Up There descends Down Here for an instant. The world connects to a mystery -- a happening that cannot be explained in the terms of ordinary life...
...against smog may soon get a new high-tech weapon. A device being tested in Provo, Utah, uses an infrared beam, computer software and a video camera to add up the carbon monoxide and hydrocarbons billowing from the tail pipes of passing cars -- and to automatically record their license numbers...
