Researchers create transistors out of nanowire forests, for ultimate scaling beyond 10nm
2013-05-01 20:00:44| Extremetech
As transistor size decreases, the limits of planar technologies have been partially alleviated by stepping into the third dimension. Researchers in France have come up with a 3D transistor design based on silicon nanowires that promises to extend lithographic techniques down to ever smaller scales.

Fires Burn More Fiercely As Northern Forests Warm
2013-04-25 15:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: When the wildfire reached Jon Cummings backyard last summer, it had already traversed 50 miles of rugged terrain in Idahos Salmon-Challis National Forest. Thick smoke dimmed daylight and embers sailed on hot currents. While firefighters were able to preserve Cummings house and property, his neighbors up the river were less fortunate. No houses burned, but when those folks came home it was a total moonscape, he said. Wildfires last summer burned more than 9 million acres across the U.S., predominantly...

Why action on forests now is essential to all our futures
2013-04-20 12:15:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: While forests once provided subsistence for local people, for generations clearing forested land has also been good for global business, providing immediate food security for the world. Put simply, forests have been worth more dead than alive. As populations grow, emerging and industrialised countries are looking to the three great world forest regions the Three Basins of the Congo, the Amazon and south-east Asia for their growing resource needs. The economic imperative to acquire and clear...
Investing in healthy forests vital for transition to green economy, UN says
2013-04-19 04:34:00| Climate Ark Climate Change & Global Warming Newsfeed
Big News Network: Investing in healthy forests is not only vital for human and environmental well-being but also crucial in the transition to a low-carbon, resource-efficient green economy, says the United Nations Environment Programme (UNEP). Over a billion people worldwide depend on forests for shelter, jobs, food, water, medicine and security. Forests also serve as carbon sinks and stabilize global climate, regulate water cycles and provide habitats for biodiversity while hosting a wide variety of genetic resources....
Pine bark beetles poised for new attacks on Canada's northern and eastern forests
2013-04-11 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: After more than a decade, the mountain pine beetle epidemic that surged through British Columbia appears finally to be in remission. Having devastated the province's lodgepole pine forests, the insect is running out of food. But forest managers now see new beetle infestations appearing at the edge of the Boreal Forest, in Alberta, and in the Yukon and Northwest Territories -- areas well outside the insect's historical range. As a warming climate lifts the temperature limitations that once kept...
