Wastewater treatment process may keep fish off antidepressants

By - February 27, 2013 2 Pictures
While some people may wonder about the possible side-effects of antidepressants on the people who are taking them, here’s another thing to consider ... what happens when the residue from those drugs passes through the user’s urine and into the sewage system? As it turns out, it can enter local waterways and affect the fish. Now, researchers from KTH Royal Institute of Technology in Stockholm have developed technology to keep that from happening.

Carbon-capture material releases trapped CO2 when exposed to sunlight

By - February 13, 2013
Amidst concerns over the accumulation of atmospheric greenhouse gases, many research institutes have been looking into methods of carbon sequestration – the capture, storage and even possible reuse of carbon dioxide emissions. Unfortunately, some of the approaches require a considerable input of power, in order to release the captured CO2. A new material developed at Australia’s Monash University, however, requires nothing but sunlight. Read More

Graphene oxide causes radioactive material to "clump" out of water

By - January 12, 2013 2 Pictures
Removing radioactive material from contaminated water, such as that in Japan’s Fukushima nuclear power plants, could be getting a little easier. Scientists from Houston’s Rice University and Lomonosov Moscow State University have discovered that when flakes of graphene oxide are added to such water, it causes the radionuclides to condense into clumps. Those clumps can then be separated and disposed of. Read More

Olive oil may save York Minster cathedral

By - January 11, 2013 6 Pictures
York Minster is one of the largest Gothic cathedrals in Northern Europe and one of the great monuments of medieval architecture. Built in the city of York, UK between 1220 and 1472, it has suffered looting, vandalism, arson and a devastating fire after a lightning strike in 1984. Despite decades of restoration costing millions of pounds, the Minster still faces an implacable enemy, the air itself. In hopes of protecting the Minster from rotting away due to air pollution, Dr. Karen Wilson and Prof. Adam Lee of the Cardiff School of Chemistry, Cardiff University along with researchers at the University of Iowa have discovered that the key to saving the church may lie in olive oil.

Portable sensor lets users monitor air pollution on their smartphone

By - December 19, 2012 3 Pictures
Air quality is one of those things that many of us should be more concerned about, but aren’t. According to some people, this is because we’re not easily able to know how clean the air around us really is – we just assume it’s “clean enough.” Computer scientists at the University of California, San Diego have set out to change that. They’re developing a compact, portable air pollution sensor that communicates with the user’s smartphone, to provide real-time air quality readings for their immediate surroundings. Read More

New software improves measurement of greenhouse gas emissions

By - October 22, 2012
As the old adage goes, knowledge is power. Following this principle, Arizona State University researchers have developed a computer program called Hestia, that is capable of estimating the greenhouse gas emissions of specific roads and even buildings. With its high level level of detail and accuracy, the software can help cities make more precise calculations about their GHG footprint as well as more informed decisions related to carbon mitigation efforts.

Liquid laundry additive turns clothes into air purifiers

By - October 1, 2012 3 Pictures
A laundry additive created by researchers from the University of Sheffield and the London College of Fashion turns clothing into a photocatalytic material that can help remove nitrogen oxides (NOx) from the air. One of the most prominent air pollutants, nitrogen oxides are emitted from the exhausts of ICE-powered vehicles and aggravate asthma and other respiratory diseases. The researchers claim one person getting around town in clothing treated with the additive for a day would be able to remove roughly the same amount of nitrogen oxides produced by the average family car each day.
