'Dark Oxidants' Form Away from Sunlight in Lake nike free run and Ocean Depths, Underground Soils This horloges material is available primarily for archivalpurposes. Telephone numbers or other contact information maybe out of date; please see current contact information at mediacontacts. Breathing nba jerseys oxygen...can be hazardous to your health? Indeed, our bodies burberry uk aren't perfect. They marc jacobs make mistakes, hugo boss online among patriots nfl jersey them producing toxic chemicals, called oxidants, in cells. We wizards jersey fight these oxidants naturally, and by steelers nfl jersey eating foods rich in antioxidants such as blueberries and pandora uk dark chocolate.

All forms of life that breathe oxygen--even ones coach outlet that can't be seen with the naked eye, such as bacteria--must burberry canada fight oxidants to live. "If they don't," says scientist Colleen Hansel of the Woods Hole Oceanographic Institution in Massachusetts, "there mont blanc pens are consequences: cancer and premature aging in humans, death in microorganisms." chi flat iron These same oxidants also exist in the environment. But neutralizing environmental oxidants such as superoxide was a barbour jackets worry only for organisms that dwell in sunlight--in habitats that cover a mere 5 redskins nfl jersey percent new balance outlet of the planet. That was the only ray ban place chiefs nfl jersey where such lacoste outlet environmental oxidants were thought to exist. Now researchers have discovered the first light-independent source of superoxide.

The key is bacteria common in the depths of the oceans and other dark places. The bacteria suns jersey breathe oxygen, just like humans. "And they're everywhere--literally," says Hansel, co-author of a paper reporting philipp plein outlet the results oakley sungalsses outlet and published in this week's issue 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 nets jerseys fact, 90 percent jordan retro of the bacteria tested oakley outlet online in iphone case the study produced superoxide in the dark. "Superoxide the north face jackets has been linked with light, such that its production in darkness was a real mystery," says Deborah Bronk of ravens nfl jersey the National michael kors outlet Science Foundation's (NSF) Division of Ocean Sciences, which co-funded the research with NSF's Division of Earth Sciences.

"This finding shows that bacteria can produce superoxide cheap jordans 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 Earth's surface, "superoxide can kill corals, turning them white," says Hansel. "It can also produce huge fish kills during red tides. But it's not always oakley vault bad." It also helps ocean microorganisms acquire the nutrients they need to survive.

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