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.

Simpler model gets to the point with proteins

Computational models have come a long way in their ability to simulate the most basic biological processes, such as how proteins fold. A new technique should enable scientists to model larger molecules with greater accuracy than ever. The researchers have developed a molecular modeling framework that can more accurately reproduce experimental results with simple coarse-grained models used to simulate protein dynamics. The framework, Observable-driven Design of Effective Molecular Models, incorporates available experimental data in the definition of a coarse-grained simulation model. For a given coarse-grained model, repeating the simulation with incremental changes in the model parameters improves the algorithm's ability to predict, for instance, how a protein will find its functional form. The researchers found their technique can reveal unanticipated molecular properties.
