Chemists harvest light to create 'green' tool for pharmaceuticals
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.

Carbonized coffee grounds remove foul smells
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.

More environmental rules needed for shale gas, says geophysicist
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.

New material to remove radioactive gas from spent nuclear fuel
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.

Major environmental study finds traces of many drugs in Swedish waters
High levels of the anti-inflammatory substance diclofenac are released from wastewater plants, according to a new study.

Satellite imagery detects thermal 'uplift' signal of underground nuclear tests
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.

Reuse of municipal wastewater has potential to augment future drinking water supplies
With recent advances in technology and design, treating municipal wastewater and reusing it for drinking water, irrigation, industry, and other applications could significantly increase the nation's total available water resources, particularly in coastal areas facing water shortages.

New technology removes air pollutants, may reduce energy use in animal agricultural facilities
Researchers have developed a new technology that can reduce air pollutant emissions from some chicken and swine barns, and also reduce their energy use by recovering and possibly generating heat.

Debris scatters in the Pacific Ocean, possibly heading to US
Debris from the tsunami that devastated Japan in March could reach the United States as early as this winter, according to new predictions. However, they warn there is still a large amount of uncertainty over exactly what is still floating, where it's located, where it will go, and when it will arrive. Responders now have a challenging, if not impossible situation on their hands: How do you deal with debris that could now impact US shores, but is difficult to find?

Go to work on a Christmas card: UK's wrapping paper and festive cards could provide energy to send a bus to the moon more than 20 times
If all the UK's discarded wrapping paper and Christmas cards were collected and fermented, they could make enough biofuel to run a double-decker bus to the moon and back more than 20 times, according to the researchers behind a new scientific study.

Sea cucumbers: Dissolving coral reefs?
Coral reefs are extremely diverse ecosystems that support enormous biodiversity. But they are at risk. Carbon dioxide emissions are acidifying the ocean, threatening reefs and other marine organisms. New research analyzed the role of sea cucumbers in portions of the Great Barrier Reef and determined that their dietary process of dissolving calcium carbonate (CaCO3) from the surrounding reef accounts for about half of at the total nighttime dissolution for the reef.

New method of cleaning toxins from oilsands
Researchers have isolated biofilms that are indigenous to the oilsands environment and are highly tolerant to the stress associated with toxins and metals found in tailings water. Those consortia of biofilms are able to, slowly, detoxify the water.

What if if Virginia lifts ban on uranium mining? Report identifies health and environmental issues
A number of health and environmental issues and related risks need to be addressed when considering whether to lift the almost 30-year moratorium on uranium mining in Virginia, a new report says.
-
Novel device removes heavy metals from water
Engineers have developed a system that cleanly and efficiently removes trace heavy metals from water. In experiments, the researchers showed the system reduced cadmium, copper, and nickel concentrations, returning contaminated water to near or below federally acceptable standards. The technique is scalable and has viable commercial applications, especially in the environmental remediation and metal recovery fields.

Increasing atmospheric concentrations of new flame retardants found
Compounds used in new flame-retardant products are showing up in the environment at increasing concentrations, according to a recent study.

Sewage treatment plants may contribute to antibiotic resistance problem
Water discharged into lakes and rivers from municipal sewage treatment plants may contain significant concentrations of the genes that make bacteria antibiotic-resistant. That's the conclusion of a new study on a sewage treatment plant on Lake Superior in the Duluth, Minn., harbor.

Abnormal levels of caffeine in water indicate human contamination
Researchers have discovered that traces of caffeine are a useful indicator of the contamination of our water by sewers.

U.S. Marines test new energy-efficient weapon in the war on trash
U.S. Marines are testing a high-tech trash disposal system that can reduce a standard 50-gallon bag of waste to a half-pint jar of harmless ash. Called the Micro Auto Gasification System, the unit is currently undergoing evaluation by US Marine Corps Forces, Pacific as a possible solution to help Marines win their daily battle against the increasing trash at remote forward operating bases.

Making chemicals from biogas instead of burning it
Combustible gases generated by organic matter in landfill sites or from biomass are commonly burned to generate electricity. However, Finnish researchers suggest that such biogas might be more usefully used as an alternative feedstock for the chemical industry. They explain that using biogas in this way would reduce our dependency on oil and gas-derived products and is commercially and technically viable.

Even the cleanest wastewater contributes to more 'super bacteria', study finds
A new study reveals that the release of treated municipal wastewater -- even wastewater treated by the highest-quality treatment technology -- can have a significant effect on the quantities of antibiotic-resistant bacteria, often referred to as "superbacteria," in surface waters.
