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.

Picture of the Day

Researchers develop 3D printed objects that can track and store how they are used

Cheap and easily customizable, 3D printed devices are perfect for assistive technology like prosthetics or "smart" pill bottles that can help patients remember to take their daily medications. But these plastic parts don't have electronics, which means they can't monitor how patients are using them. Now, National Science Foundation-funded scientists have developed 3D printed devices that can track and store their own use -- without using batteries or electronics. Instead, this system uses a method called backscatter through which a device can share information by reflecting signals that have been transmitted to it with an antenna. Previously, the team developed the first 3D printed objects that connect to Wi-Fi without electronics. These purely plastic devices can measure if a detergent bottle is running low and then automatically order more online.
