Researchers examine carbon capture and storage to combat global warming

...n, coordinating lead author of the IPCC chapter on underground geological storage. With fossil fuels already comprising 85 percent of the world's energy consumption, and their use rapidly increasing due to the growth of developing countries, such as China and India, the need to find solutions to curb carbon e...

In nature, proteins sweep up nanoparticles

... into piles that are too large to be swept away by underground currents. Precisely how and why the bacteria undertake this bit of housecleaning remains a mystery, but it suggests that proteins could play a key role in bioremediation strategies designed to trap harmful metals such as arsenic, lead, uranium, and p...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

...alled triazine, often causes contamination both of underground water and overground water. For this reason food safety agencies have established control measures to prevent these pesticides entering the food chain. Similarly, antibiotics used to treat bacterial infections in domestic animals, such as the case of...

Mine runoff continues to provide clues to microbial diversification

...al community thriving in battery acid-like streams underground at Richmond Mine near Redding, Calif., combines recently developed ways to sequence microbial genes with methods to identify the range of proteins from specific microbial members.

Ventura and his colleagues discovered that the rocks contained a type of lipid, or oily compound, found only in archaeal cell membranes. This finding indicates that an archaean community may have inhabited the region mor...

Tulane researcher reports on origin of deadly fever outbreak

Fire ants: Their true story told by the scientist who loves them

...ure colony can encompass approximately 300 feet of underground foraging tunnels ?about 20,000 ant body-lengths. On a human scale, that's the staggering equivalent of 20 miles or more. On the FSU faculty since 1970, Tschinkel's wide-ranging research has also encompassed the ecology of arboreal ants (a main food ...

Deep-rooted plants have much greater impact on climate than experts thought

...sfer rainwater from the surface to reservoirs deep underground and redistribute water upwards after the rains to keep the top layers moist, thereby accentuating both carbon uptake and localized atmospheric cooling during dry periods. The researchers estimate this effect increases photosynthesis and the evaporat...

Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning

...ng a particular class of insects to expose the key underground carbon traffic system - by eating it. The University of Warwick team worked with researchers from Aberdeen, Lancaster and Sheffield, to try and establish if plant associated fungi - arbulscar mycorrhizal (AM) fungi - found on the roots of 80% of all...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality
