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.

New LEDs may offer better way to clean water in remote areas

For the first time, researchers have created light-emitting diodes (LEDs) on lightweight flexible metal foil. National Science Foundation-funded engineers at the Ohio State University are developing the foil based LEDs for portable ultraviolet (UV) lights that soldiers and others can use to purify drinking water and sterilize medical equipment. According to the researchers, they designed the LEDs to shine in the high-energy “deep” end of the UV spectrum. The university will license the technology to industry for further development. Deep UV light is already used by the military, humanitarian organizations and industry for applications ranging from detection of biological agents to curing plastics.
