Technology. (Science News of the year: the weekly newsmagazine of science).Pocket power For cell phones and other portable electronics, researchers field-tested prototypes of tiny, refillable fuel cells expected to last much longer than today's batteries (162: 155 *). Biomed structures Chemists synthesized new gelatinous gelatinous /ge·lat·i·nous/ (je-lat´i-nus) like jelly or softened gelatin. ge·lat·i·nous adj. 1. Of, relating to, or containing gelatin. 2. Resembling gelatin; viscous. and rubbery polymers that may serve as superior dressings for wounds (162: 20) and as scaffolds for artificial organs artificial organs, n.pl the devices used to support life because of the failure or limited capacity of the human organ. The most effective is the artificial kidney, which consists of a set of tubes that pass the blood through a dialysate solution where and tissues (161: 323,408; 162: 93). Attractively cool A compact cooler incorporating a permanent magnet showed that it could give rise to household refrigerators and air conditioners that depend on magnetism instead of volatile liquids (161: 4 *). Microplumblng Researchers packed thousands of microscopic pipes and chambers onto fluid-manipulating microchips of unprecedented power (162: 198). Hot cross beams Novel microstructures of crisscrossed criss·cross v. criss·crossed, criss·cross·ing, criss·cross·es v.tr. 1. To mark with crossing lines. 2. tungsten rods filtered various wavelengths of radiated ra·di·ate v. ra·di·at·ed, ra·di·at·ing, ra·di·ates v.intr. 1. To send out rays or waves. 2. To issue or emerge in rays or waves: Heat radiated from the stove. heat--a talent that someday might boost the efficiency of lightbulbs (161: 334). Billowy bil·low n. 1. A large wave or swell of water. 2. A great swell, surge, or undulating mass, as of smoke or sound. v. bil·lowed, bil·low·ing, bil·lows v.intr. 1. billboards? An electronic display capped by a transparent polymer membrane applied as a liquid and then solidified may be a step toward paint-on displays for walls and fabrics (161: 349). * An asterisk indicates that the text of the item is available free on SCIENCE NEWS ONLINE (http://www.sciencenews.org). |
