Flexible all-carbon electronics integrated onto plants, insects, and more
Flexible supercapacitor raises bar for volumetric energy density
Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing and power wearable medical monitors, communications equipment or other small electronics.
Climate change increases risk of crop slowdown in next 20 years
The world faces a small but substantially increased risk over the next two decades of a major slowdown in the growth of global crop yields because of climate change, new research finds.
Obama mocks foes who brand climate change a 'liberal plot'
US President Barack Obama mocked Republicans who reject global warming as a "liberal plot," as he pumped up a crowd of environmental activists in Washington.
To address climate change, nothing substitutes for reducing CO2 emissions
The politically expedient way to mitigate climate change is essentially no way at all, according to a comprehensive new study by University of Chicago climatologist Raymond Pierrehumbert.
Scientists shoot carbon nanotubes out of high-speed gun (w/ video)
Minimum CO2 price of $32 needed to curb warming, study shows
A global carbon price of at least $32 (24 euros) per tonne is needed by 2015 to apply an effective brake on global warming—almost five times today's European market rate, a study said Monday.
Discovery provides insights on how plants respond to elevated CO2 levels
Biologists at UC San Diego have solved a long-standing mystery concerning the way plants reduce the numbers of their breathing pores in response to rising carbon dioxide levels in the atmosphere.
Project at IBM looks to carbon nanotube future
Dissolved iron in North Atlantic traced to sources
Iron is present in tiny concentrations in seawater. On the order of a few billionths of a gram in a liter.
Reducing emissions will be the primary way to fight climate change, study finds
Forget about positioning giant mirrors in space to reduce the amount of sunlight being trapped in the earth's atmosphere or seeding clouds to reduce the amount of light entering earth's atmosphere. Those approaches to climate ...
Earth's breathable atmosphere tied to plate tectonics?
The rise of oxygen is one of the biggest puzzle in Earth's history. Our planet's atmosphere started out oxygen-free. Then, around 3.5 billion years ago, tiny microbes called cyanobacteria (or blue-green algae) ...
Australia carbon tax repeal a 'perfect storm of stupidity'
Australia's axing of its carbon tax and a plan to replace it by offering incentives to polluters to increase their energy efficiency is "the perfect storm of stupidity", scientists and academics argue.
Buried fossil soils found to be awash in carbon
Soils that formed on the Earth's surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet's ...
