Exciting change is on the way! Please join us at nsf.gov for the latest news on NSF-funded research. While the NSF Science360 page and daily newsletter have now been retired, there’s much happening at nsf.gov. You’ll find current research news on the homepage and much more to explore throughout the site. Best of all, we’ve begun to build a brand-new website that will bring together news, social media, multimedia and more in a way that offers visitors a rich, rewarding, user-friendly experience.

Want to continue to receive email updates on the latest NSF research news and multimedia content? On September 23rd we’ll begin sending those updates via GovDelivery. If you’d prefer not to receive them, please unsubscribe now from Science360 News and your email address will not be moved into the new system.

Thanks so much for being part of the NSF Science360 News Service community. We hope you’ll stay with us during this transition so that we can continue to share the many ways NSF-funded research is advancing knowledge that transforms our future.

Shining light on landfills to uncover 'dark life'

Researchers increasingly turn to computational genomics to assist in bioremediation, a process that uses naturally occurring organisms to help turn hazardous wastes into less toxic or non-toxic materials. Assistant Professor Laura Hug at the University of Waterloo in Canada explains how municipal landfills are mined for new types of bacteria -- called "dark life" -- because many such organisms were not previously known to exist. Scientists extract DNA from such microbes and sequence it using supercomputers such as San Diego Supercomputer Center's petascale Comet system.
