New paper alert! Check out this new paper "The sociobiome-oral microbiome mediates dental caries among Indigenous Australians" by Nath et al., 2025 pubmed.ncbi.nlm.nih.gov/41479542/ Super proud to be a part of this amazing work! Great work, Sonia!!

So proud to be part of research projects providing dental care to our participants. If research integrates communities with equal benefits, it needs to be funded to ensure that's possible! Excellent paper, Gina! onlinelibrary.wiley.com/doi/10.1111/...

Great job to our team member, Shah Imran Hossain, on his excellent presentation ‘From Dysbiosis to Balance: Restoring Oral Health Through Microbiome Transplantation’ at the Penn State Eberly Research Showcase: From Molecules to Galaxies!

New preprint on bioRxiv! The sociobiome–oral microbiome pathway in dental caries among Indigenous Australians” by Sonia Nath et al. doi.org/10.1101/2025...

🎉 New from our team: lab methods can shape what we recover from ancient dental calculus! Extraction & library prep choices influence results, highlighting the importance of careful protocols for reproducible ancient microbiome research. onlinelibrary.wiley.com/doi/10.1111/... Check it out today!!

🦠 New Matters Microbial with @markowenmartin.bsky.social! Guest Dr. @lauraweyrich.bsky.social shares how ancient dental plaque DNA reveals: – Neanderthal diets & health – Early “medicine” use – Microbes shared with humans 🎧 www.youtube.com/watch?v=6Bc5...

Another week, another episode of #MattersMicrobial podcast! This time, @lauraweyrich.bsky.social of Penn State discusses what bacterial DNA from ancient dental plaque can tell us. Please spread the #GoodMicrobialWord. @univpugetsound @asmicrobiology @microbe.tv youtu.be/6Bc5jhCDWg8?...

Great to see initiatives working on policy improvements for microbiome conservation! So wonderful to see the forethought to also include broad representation! Exciting! www.nature.com/articles/s41...

@microarch-lab.bsky.social was lucky enough to host and work with @bbonucci.bsky.social this summer. Checkout her recent publication on retrieving #ancientDNA from concretions from human remains!

Checkout this new #ancientDNA research published today on mastodons significantly revising the previous understanding of their evolutionary history!

Meet Shah Imran Hossain, a graduate student in Biotechnology at Penn State. Shah is part of the Oral Microbiome Transplants (OMT) project, where he studies how microbial communities in the mouth can be shifted to help treat oral diseases like caries, periodontal disease, gingivitis, and oral cancers

OPEN INVITATION to the One Health Microbiome Symposium, May 13-14, 2026!! This is not your typical siloed topic conference. It unifies diverse research fields in microbiome science across Ag, Envtl, and Human Health. 1/n www.eventbrite.com/e/2026-one-h...

Congratulations to our PhD student, Christine Ta @ckayeeta.bsky.social on being awarded the One Health Microbiome interdisciplinary Innovation Fellowship!! We are super proud of you!

🚨Thrilled to share our new paper!! We were able to retrieve ancient DNA and proteins from layers of sediment attached to the skeletal remains of individuals from a Neolithic site from Southern Italy 💀🧬🦠 www.cell.com/iscience/ful...

Great job presenting today @bbonucci.bsky.social #ISBA11 @isba11.bsky.social

Ancient DNA reveals farming spread through migration—not local adoption. Penn State-led study shows migration drove nearly all of Europe’s Neolithic farming transition, with cultural adoption contributing only minimally. Congratulations to the Huber lab!!! www.psu.edu/news/researc...

Great job presenting today @wicedjuju.bsky.social #ISBA11 @isba11.bsky.social
