New software improves measurement of greenhouse gas emissions

By - October 22, 2012 1 Picture
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.

Gravity probe shows groundwater reserves slipping away

By - September 25, 2012 7 Pictures
Recently, drought seems to be a fact of life. As the lead photograph poignantly illustrates, most of the U.S. has been struggling with serious levels of drought for the past several years. Worldwide, drought affected areas include Europe, India and Pakistan, Russia, much of Africa, South America – the list goes on. But when the rains start again, everyone expresses great relief, not realizing that long-term depletion of groundwater reserves is part of the price for surviving drought. It was with this in mind that GRACE (Gravity Recovery and Climate Experiment), a joint U.S. and German space project, was designed a decade ago. Read More

MIT researchers devise technique to clean up oil spills using magnets

By - September 12, 2012 1 Picture
Possibly the only good thing to come out of the Deepwater Horizon disaster is the subsequent increase in research into finding more effective ways to clean up oil spills, including such initiatives as the X PRIZE Foundation's Wendy Schmidt Oil Cleanup X CHALLENGE. Joining the list is a new method devised by researchers at MIT who propose separating oil and water using magnets. The new technique would allow the oil to be recovered to help offset the costs of the cleanup operation. Read More

“Nano-velcro” traps and detects heavy metals in contaminated waterways

By - September 11, 2012 1 Picture
While progress has been made in reducing the amount of heavy metal pollution, the very nature of heavy metal contamination means it continues to be a problem in waterways around the world. Conventional heavy metal contamination detection methods require sending samples off to a lab for analysis on expensive equipment. Now a Swiss-American team has developed a cheap way to immediately ascertain the levels of heavy metals in lakes and rivers and the fish pulled out of them. Read More

Glycerol additive makes cruise ships greener

The bunker fuel used in cruise liners and freighters is some of the cheapest, crudest fuel available. It’s also among the dirtiest. Scientists from the Maine Maritime Academy and SeaChange Group LLC led by George N. Harakas, Ph.D announced at the 244th National Meeting & Exposition of the American Chemical Society that they have developed what they call "Bunker Green" fuel. This fuel uses an ingredient commonly used in food and medicine to reduce sulfur and other emissions in ocean vessels. Read More

Panansonic develops world's most efficient artificial photosynthesis system

By - August 2, 2012 3 Pictures
Panasonic has recently developed an artificial photosynthesis system that, using a simple and straightforward process, can convert carbon dioxide into clean organic materials with what it says record efficiency. This development may lead to the creation of a compact way of capturing pollution from incinerators and electric power plants and converting them into harmless – even useful – compounds. Read More
