Laundry Vents Emit Hazardous Fumes from Scented Products [Updated]
Researchers at University of Washington in Seattle and Battelle Memorial Institute in Columbus, Ohio have found the air vented from machines using scented liquid laundry detergents and dryer sheets contains hazardous chemicals. Their findings appear online in the journal Air Quality, Atmosphere and Health (paid subscription required). A team led by UW engineering professor Anne…

New Treatment Fixes Tooth Decay Without Drilling
Researchers at University of Leeds in the U.K. have developed a way of treating dental decay that reverses the damage caused by acid and re-builds teeth, without drilling. The technology developed at Leeds has been licensed to a company in Switzerland for commercialization. Dental cavities are caused by a process that begins with bacteria, which…

Solid-State Supercapacitor Created with Carbon Nanotubes
Researchers at Rice University in Houston have developed a supercapacitor that can store large quantities of energy and charge quickly, and in a solid-state design made possible by the use of carbon nanotubes. Their findings appear online in the journal Carbon (paid subscription required). Capacitors are devices that regulate flow or supply quick bursts of…

Microbes Reduced Adverse Impact of BP, Exxon Valdez Spills
A review of the worst two oil spills in U.S. history shows that oil-degrading microorganisms played a significant role in reducing their overall adverse environmental impacts. The results of the review of the 2010 BP oil spill in the Gulf of Mexico and Exxon Valdez running aground in Alaska’s Prince William Sound in 1989 are…

Bio-Based Resins, Coatings Developed from Common Crops
Researchers at North Dakota State University in Fargo have developed a family of resins from renewable raw materials that eliminate hazardous components yet perform as well the originals. The team reported its findings earlier this year in the journal Biomacromolecules (paid subscription required). The researchers led by Dean Webster, professor in the NDSU Department of…

Bacteria Metabolism Reversed to Produce High-Speed Biofuel
A new method developed by researchers at Rice University in Houston turns simple glucose into biofuels and petrochemical substitutes by reversing a metabolic process called beta oxidation using genetically modified bacteria. Engineering professor Ramon Gonzalez and colleagues published their findings online in the journal Nature (paid subscription required). The beta oxidation process is a basic…
