Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution-control systems to further reduce emissions of smog-causing nitrogen oxides in diesel exhaust.

CFCs, greenhouse gases, and naturally occurring emissions of halogens will shape how volcanoes impact the ozone layer into the next century 

With more than two dozen companies in Pennsylvania manufacturing potato chips, it is no wonder that researchers in Penn State's College of Agricultural Sciences have developed a novel approach to more efficiently convert potato waste into ethanol. This process may lead to reduced production costs for biofuel in the future and add extra value for chip makers.

In a new study, researchers at The Ohio State University estimate algal blooms at two Ohio lakes cost Ohio homeowners $152 million in lost property value over six years.

Meanwhile, a related study suggests that algae is driving anglers away from Lake Erie, causing fishing license sales to drop at least 10 percent every time a bloom reaches a moderate level of health risk. Based on those numbers, a computer model projects that a severe, summer-long bloom would cause up to $5.6 million in lost fishing revenue and associated expenditures by anglers.

NASA’s Aqua satellite and NOAA's GOES-East satellite provided an infrared and visible look at Atlantic Hurricane Gert. Both images showed the storm was being affected by wind shear and had become elongated.
