Drug Activated by Laser May Fight Cancer...
Massachusetts General Hospital (MGH) researchers are studying a new cancer-fighting drug, BDP-MA, which is activated by shining a laser on patients who have taken...
...there's a no-muss new method: using a $3 million combination of industrial-grade lasers, you can vaporize the skin right off the potatoes as they fly through a funnel at the rate of 1,800 a minute. This laser surgery for spuds, designed by researchers at Battelle Memorial Institute in Columbus, works even better on tomatoes, a key commodity for catsup-making Heinz, which owns the still experimental technology. Ore-Ida won't update its recipe for peeling potatoes until the price of lasers, already declining, drops even more. Any commercial use of laser peeling is at least...
...LASER TRAPS. Beams of laser light can also be used to ensnare groups of atoms, which can then be moved around at will. But because atoms at room temperature zoom about at supersonic speed, they first have to be slowed down. In 1985 the invention of "optical molasses" by a research team at AT&T Bell Laboratories provided an ingenious solution to the problem. As its name implies, optical molasses uses light to create enough electromagnetic "drag" to bring wildly careering atoms to a screeching halt. Because the atoms lose virtually all their kinetic energy, they approach the perfect stillness...
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...
