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.

Museum sack-bearer moth specimens generate new possibilities for DNA research

Ryan St. Laurent, a doctoral student in the Kawahara Lab at the Florida Museum of Natural History, studies an obscure, strange family of moths known as Mimallonidae, or sack-bearer moths. As caterpillars, these insects make little houses out of poop, silk and plant material to protect themselves from danger. St. Laurent published a study showing that certain molecular techniques can allow researchers to extract as much DNA from dried museum sack-bearer moth specimens as from ethanol-preserved, recently collected material. Showing the success of this technique opens the door to countless studies based on DNA from dried specimens.
