"As Nuclear Reactor Fleet Ages, Engineers Ask,' Is 80 the New 40?'" by Paul Voosen

(Article courtesy: The New York Times and Greenwire)
Could nuclear power plants last as long as the Hoover Dam?

Increasingly dependable and emitting few greenhouse gases, the U.S. fleet of nuclear power plants will likely run for another 50 or even 70 years before it is retired -- long past the 40-year life span planned decades ago -- according to industry executives, regulators and scientists.

With nuclear providing always-on electricity that will become more cost-effective if a price is placed on heat-trapping carbon dioxide emissions, utilities have found it is now viable to replace turbines or lids that have been worn down by radiation exposure or wear. Many engineers are convinced that nearly any plant parts, most of which were not designed to be replaced, can be swapped out.

"Carbon Markets Struggling to Emerge From Communism's Rubble," by Paul Voosen

A surplus of U.N. carbon emission credits piling up across Central and Eastern Europe is threatening to destabilize nascent carbon markets across the world and dampen efforts to curb global warming, market experts and politicians say.

Already this year, sales of emission credits from countries like the Czech Republic, Latvia and most notably Ukraine have caused the price of a ton of carbon in Europe's cap-and-trade system to plunge by more than a euro, a significant drop, said Kevin James, the vice president of carbon finance at Climate Change Capital.

To date, some 147 million tons of the credits -- known in U.N. legalese as assigned amount units and in policy circles as "hot air" -- have been sold worldwide under the Kyoto Protocol, according to a recent analysis by Point Carbon. Ukraine alone is estimated to be in negotiations to sell an additional 450 million tons to Japanese firms, said Andreas Türk, a Kyoto consultant at Joanneum Research in Austria.

"Quiet Biotech Revolution Transforming Crops," by Paul Voosen

Fourth in a five-part series about genetically modified crops.

For the past two decades, promises of crop improvement have been the domain of genetically modified plants: mostly, crops supplemented with bacterial genes to resist pests or weedkillers like Roundup. More than 85 percent of U.S. corn, soy or cotton grown contains such genes.

But there is more than one way to transform a plant.

Using advanced biotechnology, long hidden in the background and only now starting to pay dividends, scientists are changing crops without tapping foreign genes -- and often without the regulatory oversight that is given to GM crops.

"Courts Force U.S. Reckoning With Dominance of GM Crops," by Paul Voose

Article: courtesy New York Times & Greenwire

"These days, there is no rarer commodity in farming than trust.

Take Oregon's Willamette Valley, which for generations has been the germ of the U.S. sugar beet industry, producing nearly all the country's seeds. Such breeding is complicated when neighbors grow genetically similar crops and stiff Pacific winds, baffled by the Coast Range mountains, shove pollen every which way.

But Willamette's growers have cooperated, establishing a system in which seed producers flag their plots on a collective map, giving fair warning of what is grown where. Voluntary distances between crops were established and, if abutting farms had a conflict in what they grew, well, they could usually figure it out."

"Biodiversity a Bitter Pill in 'Tropical' Mediterranean Sea," by Paul Voosen

Article: Courtesy New York Times & Greenwire

"Two weeks ago, a group of marine biologists from Israel's National Institute of Oceanography set sail from the country's central coast. Under a full moon, with the lights of hectic Tel Aviv a band on the horizon, they cast their nets into waters that have sustained civilization for millenia in the Levantine Basin, the eastern branch of the Mediterranean Sea.

They had a rich catch that night on the research vessel Shikmona, according to Bella Galil, a senior scientist at the institute. Spilling from the nets were pucker-faced dragonet fish, sprawling octopuses and brown crabs, snapping their claws. On the examination table, it seemed a display of the sea's bounty.

Unfortunately, it was another sea's bounty."

"Could Auto Battery Advances Lead to Better Robots?" by Paul Voosen

Article courtesy Greenwire and The New York Times:

"Every robot has its limit.

For the famous Roomba vacuum, it's two to three hours. For the several thousand robots deployed in Iraq, about the same. For the warehouse robots sorting our sneaker orders, eight hours. And the Energizer Bunny? Forget about it -- a few minutes, tops.

Perhaps more than any other factor, the life span of batteries has limited the infiltration of robotics into daily life. As computer processing and sensors have become cheaper and more powerful by the year, batteries, woefully inefficient and slow to recharge, have slogged behind, leaving engineers to dream of a day when they'll have the juice to give life to their boldest creations."
