From WebWire: "On April 12, two technologies developed at NASA for America's space program will be inducted into the Space Foundation's Space Technology Hall of Fame. NASA's Johnson Space Center, Houston, receives the honor for its development of the Microbial Check Valve used in water purification. NASA's Kennedy Space Center, Cape Canaveral, Fla., is recognized for the development of Emulsified Zero-Valent Iron technology used to clean contaminated ground water...
"The Microbial Check Valve is an integral component for maintaining safe drinking water in water purification systems now deployed in rural areas and developing countries around the world. Engineers at Johnson developed the system to provide microbial control for drinking water systems for the space shuttle and the International Space Station. Johnson will join the Water Security Corporation, Sparks, Nev., and Umpqua Research, Myrtle Creek, Ore., as inductees for developing the technology...
"Emulsified Zero-Valent Iron technology is a cost-effective, environmentally-friendly technology used to clean ground water contaminated by dense chemical compounds. Engineers at the Kennedy Space Center developed the technology to clean up pollution caused by chlorinated solvents used to clean Apollo rocket parts. This technology is now used at both government and private industry cleanup sites."

Arctic sea ice may be at a "tipping point" according to a study cited by the Montreal Gazette. From the article, "The meltdown in the Arctic might have reached a tipping point that could trigger a cascade of climate changes and profoundly affect the weather in Earth's temperate regions, a new study warns. 'When the ice thins to a vulnerable state, the bottom will drop out and we may quickly move into a new, seasonally ice-free state of the Arctic,' said Mark Serreze, a senior researcher at the National Snow and Ice Data Centre at the University of Colorado at Boulder and lead author of the study published today in the journal Science.
'I think there is some evidence that we may have reached that tipping point, and the impacts will not be confined to the Arctic region.' The Science paper, Perspectives on the Arctic's Shrinking Sea Ice Cover, pulls together recent research and observations and leaves little question the Arctic ice is shrinking. It says the trend in Arctic sea ice extent, which is defined as the total area where ice covers at least 15 per cent of the ocean surface, has been 'negative' every month since satellite record keeping began in 1979."
