Methane Deep In Ocean Crust Could Feed Chemical-Hungry Microorganisms
...humans. Most of the methane below the seafloor is trapped in rock as bubbles so tiny that they can be seen clearly only with a microscope. It is more likely that the methane may be used by deep-sea microorganisms. As the rock ages it continues to fracture and admit seawater. It could be that the seawate...Basin Traps Air Pollution In Mexico City: International Study Has Implications For U.S. Cities

In addition to Pacific Northwest, collaborators included Los Alamos andArgonne National Laboratory, the National O...Environmental Engineers Demonstrate Effective Method For Trapping Highway Pollutants
...project,Sansalone will try to demonstrate that the trapped metals can beremoved by a simple back-washing. That's important, because ifyou can't remove the toxic pollutants for disposal, you wind upwith tons and tons of toxic waste. Lab-scale experiments indicate the back-washing process isfeasible. However, ...Blindness Linked To The Cytoskeleton?

Indeed, the breakthrough came from such a trapped exon that showed significant homology to a transcribed sequence in the database and finally identified the full length transcript of the RP2 gene in a cDNA library. Seven out of 38 patients with X-chromosomal RP showed mutations in this...University of Florida Researchers Develop Filter Coating That Traps Bacteria and Viruses
