14-09-29 The excessive atmospheric carbon dioxide that is driving global climate change could be harnessed into a renewable energy technology that would be a win for both the environment and the economy. That is the lure of artificial photosynthesis in which...

14-09-25 Abundant supplies of natural gas will do little to reduce harmful U.S. emissions causing climate change, according to researchers at UC Irvine, Stanford University, and the nonprofit organization Near Zero. They found that inexpensive gas boosts ele...

14-09-16 Astronomers searching the atmospheres of alien worlds for gases that might be produced by life can't rely on the detection of just one type, such as oxygen, ozone, or methane, because in some cases these gases can be produced non-biologically, accor...

14-09-16 Cloud computing involves displacing data storage and processing from the user's computer on to remote servers. It can provide users with more storage space and computing power that they can then access from anywhere in the world rather than having t...

14-08-28 Recycled tires could see new life in lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by wind and solar, say researchers at the Department of Energy's Oak Ridge National Laboratory. By modifying the mic...

14-08-27 A new analysis suggests the planet can produce much more land-plant biomass -- the total material in leaves, stems, roots, fruits, grains and other terrestrial plant parts -- than previously thought. The study, reported in Environmental Science and...

14-08-27 Existing power plants around the world will pump out more than 300 billion tons of carbon dioxide over their expected lifetimes, significantly adding to atmospheric levels of the climate-warming gas, according to UC Irvine and Princeton University s...

14-08-25 The vast reservoir of carbon stored in Arctic permafrost is gradually being converted to carbon dioxide (CO2) after entering the freshwater system in a process thought to be controlled largely by microbial activity. However, a new study -- funded by...

14-08-04 Sieve elements are a key component of phloem（筛部，韧皮部） , the conductive tissue through which plants transport carbohydrates and a wide range of signalling molecules. Elongated cylindrical cells are capped at one end by a sieve plate and arrang...

14-07-22 Both shale gas and conventional natural gas have a larger greenhouse gas footprint than do coal or oil, especially for the primary uses of residential and commercial heating. Dr. Robert Howarth, a professor of ecology and environmental biology, came...
