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.

Streamlining ocean rescue

If you fall off a ship at sea, how will your rescuers find you? Using drones and dummies, an interdisciplinary team of National Science Foundation-funded mathematicians and engineers is tracking how objects move in real-world water environments. The team's findings may one day aid faster ocean rescues, speed oil-spill cleanups and even provide new tools to fight crop-killing plant diseases. When chemicals contaminate the ocean, disaster response is based on complicated simulations. This can take days for a computer to render -- meanwhile, ocean currents are spreading contaminants. That's not fast enough. How about shaving days down to minutes? Being able to predict a contaminant's movement allows for better disaster response, minimizing environmental damage, costs of cleanup and injuries on marine life. These same simulations can be used to help rescue people who fall overboard in the open ocean or help farmers forecast the spread of plant disease in the atmosphere, which can save huge costs on pesticide sprays.
