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.

Particle offers promise for vaccine in pill form

A microscopic corn-and-shrimp cocktail could eventually make DNA-based vaccinations and cancer-treating gene therapies an easier pill to swallow. In a recent study, researchers demonstrated that nesting a specialized nanoparticle inside a microparticle could protect engineered genes or virus-derived DNA against the rigors of the stomach and ensure safe passage to the intestine. Once there, that synthetic DNA could potentially enter cells to trigger the production of either disease-fighting proteins or antibodies essential to building immunity, the study found.
