15、sealed a salty Antarctic lake for more than 2,800 years, scientists have found frozen bacteria and algae that returned to life after thawing. The research may help in the search for life on Mars, which is thought to have subsurface lakes of ice.2 A research team led by Peter Doran of the University

16、Of Illinois at Chicago drilled through more than 39 feet of ice to collect samples of bacteria and algae. When Dorans team brought them back and warmed them up a bit, they sprang back to life.3 Doran said the microbes have been age-dated at 2,800 years old, but even older microbes may live deeper in

17、 the ice sheet sealing the lake, and in the briny water below the ice. That deeper ice and the water itself will be cautiously sampled in a later expedition that will test techniques that may one day be used on Mars.4 Called Lake Vida, the 4.5-square-kilometer body is one of a series of lakes locate

18、d in the McMurdo Dry Valleys of Antarctica, some 2,200 kilometers due south of New Zealand. This lake has been known since the 1950s, but people ignored it because they thought it was just a big block of ice. While at the site for other research in the 1990s, Doran and his colleagues sent radar sign

19、als into the clear ice covering the lake and were surprised to find that 62 feet below there was a pool of liquid water that was about seven times more salty than seawater.5 That prompted the researchers to return in 1996 with equipment to drill a hole down to within a few feet of the water layer. A

20、t the bottom of this hole, researchers harvested specimens of . algae and bacteria.6 The researchers will return in 2004 equipped with instruments that are sterilized. They will then drill through the full 62 feet of ice and sample some of the briny water from the lake for analysis. The water specim

The flow of electrons through the wire constitutes an electrical current that can generate power.So far, the new fuel cells dont produce much power, but the fact that they work at all is

31、exciting, says Paul Kenis, a chemical engineer at the University of Illinois at Urbana-Champaign. “Just getting it to work,“ Kenis says, “is a major accomplishment.“Sugar-eating fuel cells could be an efficient way to make electricity. Sugar is easy to find. And the new fuel cells that mn on it are

40、ades after it ceased to be the worlds tallest structure, is la Tour Eiffel still so popular?The reasons are as complex as the iron work that graces a structure some 90 stories high. But part of the answer is, no doubt, its agelessness. Regularly maintained, it should never rust away. Graffiti is reg

Yes, television and radio signals are beamed from the top, and Gustave Eiffel, a frenetic builder who died o
