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 technique helps visualize amyloid proteins, could impact disease treatment

Amyloids -- tiny protein structures that are key to understanding certain devastating age-related diseases -- are so tiny that they can't be visualized using conventional microscopic techniques. A team of engineers at Washington University in St. Louis has developed a new technique that uses temporary fluorescence, which causes amyloids to flash, or "blink," thus allowing researchers to better spot these problematic proteins. The technique is called transient amyloid binding (TAB) imaging. TAB uses a standard dye called thioflavin T, which temporarily sticks to amyloids one at a time. The effect isn't permanent, and the amyloids emit light until the dye detaches, yielding a distinctive blinking effect.
