'Dark Oxidants' Form Away from Sunlight in Lake and Ocean Depths, Underground Soils This material is available primarily for archivalpurposes. Telephone numbers or other hermes birkin contact nba jersey information maybe out of rams nfl jersey date; please see current contact information at mediacontacts. Breathing oxygen...can be hazardous to woolrich outlet your health? Indeed, our bodies aren't perfect. They make mistakes, among jack wolfskin ca them producing toxic rolex watches chemicals, called oxidants, in north face cells. We fight these oxidants naturally, and by eating foods rich in antioxidants such as saints nfl jersey blueberries ray ban and dark nike store chocolate.

All forms of life that breathe oxygen--even ones that can't be ray ban seen with the chargers nfl jersey naked eye, such thomas sabo as bacteria--must fight mont blanc pens oxidants to live. "If they don't," says scientist Colleen Hansel of the Woods Hole Oceanographic burberry outlet Institution in Massachusetts, "there are consequences: cancer and premature aging los angeles clippers jerseys in ralph lauren outlet online humans, death in microorganisms." These same mcm bags oxidants also exist in the environment. But neutralizing environmental oxidants such as superoxide was a worry only for organisms that dwell in sunlight--in habitats that true religion outlet store cover a mere 5 percent of the planet. That was the only place where such environmental oxidants were thought to exist. Now researchers have discovered the first light-independent source of superoxide. bottega

The key is bacteria common in the depths of the oceans and other dark places. The bacteria breathe oxygen, just like humans. air max 90 "And they're everywhere--literally," says Hansel, co-author of a christian louboutin paper reporting the results and published in this week's hollisterco issue ralph lauren factory store of the journal Science Express. The result expands the known sources of superoxide to the 95 percent of Earth's habitats that are "dark." In fact, 90 percent of the bacteria tested in the study produced cheap oakley superoxide in the dark. "Superoxide has been linked with guciheaven outlet light, such nfl jerseys that its production in darkness was a real mystery," dolphins nfl jersey says Deborah burberry Bronk of the National Science Foundation's (NSF) Division of Ocean Sciences, which co-funded michael kors outlet the research with NSF's Division of Earth Sciences.

"This finding shows that bacteria can produce superoxide in the absence of light." The bacteria are found "miles beneath the seafloor, in hot fluids coming from underwater volcanoes, in every type of underground soil and throughout deep lake and ocean waters," Hansel says.The number of these bacteria in a thimble of seawater or soil is greater than the human population of San Francisco. And they're all releasing large amounts of superoxide. On handbags outlet Earth's surface, "superoxide can kill corals, turning them white," says Hansel. "It can also produce huge fish kills during red tides. But hilfiger online shop it's ray ban sunglasses not always bad." It also helps ocean microorganisms acquire the nutrients they need to survive.

And superoxide may remove the neurotoxin mercury from the sea, keeping it out pelicans jersey of fish and off dinner plates. The bacteria that produce superoxide could account for the total amount new balance of the chemical in the oceans, Hansel and colleagues say, and are likely the main source in dark environments. "That's a paradigm shift that will transform our understanding of the burberry handbags outlet chemistry of the oceans, as well as of lakes and underground soils," says cheap jordans Hansel, "and of the life forms that live in and depend on them." Co-authors of the paper are Julia adidas Diaz and Chantal Mendes of Harvard University, Peter Andeer and Tong Zhang of Woods Hole Oceanographic Institution and coach outlet Bettina Voelker of the Colorado School air max 2015 of Mines.
