The sociobiome-oral microbiome mediates dental caries among Indigenous Australians - PubMed Socioeconomic disadvantage is associated with variations in the oral microbiome, and these microbial patterns may explain the link between lower income and dental health caries. Saliva may serve as a sensitive biomarker of socioeconomic gradients in oral health. These findings support integrated app …

🦠 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

@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!

Originally from Bangladesh, he completed his BSc and MS in Genetic Engineering & Biotechnology at the University of Chittagong before coming to Penn State. Outside the lab, Shah enjoys biryani and seafood. Connect with him on LinkedIn: linkedin.com/in/shahimranhossain

Welcome to the team, Shah!

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

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!

Ancient microbial DNA and proteins preserve in concretions covering human remains Microbiome; Omics; Proteomics; Archeology

🚨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 💀🧬🦠

Ancient DNA reveals farming spread through migration, locals slow to adopt it | Penn State University Roughly 10,000 years ago, humans started shifting from being nomadic hunter-gatherers to building large agricultural settlements, marking one of the greatest transformations in human history. For deca...

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.
