Bacteria normally found 30 kilometers above Earth have been identified as highly efficient generators of electricity. Bacillus stratosphericus -- a microbe commonly found in high concentrations in the stratosphere -- is a key component of a new 'super' biofilm that has been engineered by a team of scientists from Newcastle University.

A new report sheds light on current recycling practices and on socio-economic characteristics of the E-waste sector in West Africa. In the five countries studied, between 650,000 and 1,000,000 tons of domestic E-waste are generated each year, which need to be managed to protect human health and the environment in the region.

Those who have ventured to turn a vacant barn or garage into an aquaculture business have too often been defeated by high energy and feed costs, building-related woes and serious environmental problems. Now researchers are melding building design, fish ecology and aquaculture engineering techniques into a first-of-its-kind "building-integrated aquaculture" (BIAq) model to offer an affordable, more holistic and sustainable approach to indoor fish production located close to markets and able to succeed even in cold climates.

Researchers have created a new, “green” method for developing medicines. The researchers used energy from a light bulb to create an organic molecule that may be useful in the treatment of Alzheimer’s and other brain diseases.

Mushy tomatoes, brown bananas and overripe cherries -- to date, waste from wholesale markets has ended up on the compost heap at best. In future it will be put to better use: Researchers have developed a new facility that ferments this waste to make methane, which can be used to power vehicles.

In research to develop a novel, eco-friendly filter to remove toxic gases from the air, scientists found that a material made from used coffee grounds can sop up hydrogen sulfide gas, the chemical that makes raw sewage stinky.

In his State of the Union address, President Barack Obama praised the potential of the country's tremendous supply of natural gas buried in shale. But the "Halliburton exclusion" passed by Congress says gas companies don't have to disclose the chemicals used in fracturing fluids. That was a real mistake because it makes the public needlessly paranoid, says a geophysicist.

Research by chemists could impact worldwide efforts to produce clean, safe nuclear energy and reduce radioactive waste. They have used metal-organic frameworks to capture and remove volatile radioactive gas from spent nuclear fuel.

High levels of the anti-inflammatory substance diclofenac are released from wastewater plants, according to a new study.

A new analysis of satellite data from the late 1990s documents for the first time the "uplift" of ground above a site of underground nuclear testing, providing researchers a potential new tool for analyzing the strength of detonation. The findings provide another forensic tool for evaluation, especially for the potential explosive yield estimates.
