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.

Lemur study highlights role of diet in shaping gut microbiome

A study of the bacteria in the guts of three lemur species offers new insights into the role of diet in shaping these microbial ecosystems and how these microbes may relate to primate health. The researchers collected data on the nutritional composition of each species' diet in captivity. They then used genetic sequencing techniques to identify the bacterial makeup of the gut microbiome, based on fecal samples taken from representatives of each species. The researchers also used nuclear magnetic resonance spectroscopy on fecal samples to determine which chemical products were produced in the gut. By analyzing the bacteria present and the chemicals being produced, the researchers could determine how the gut microbes were making use of each lemur's diet.
