Cool, so NSF is now going to be used to essentially launder money to tech bros because universities are just too cumbersome and disciplinary oversight and regulations and accountability are all just too stifling for innovation. $1.5B for “X-Labs.”

NSF's mission is to advance the progress of science, a mission accomplished by funding proposals for research and education made by scientists, engineers, and educators from across the country.

Ecstatic to announce our newest preprint, using modular bioreactors to show that ultrasmall episymbiotic bacteria have diverse impacts on host communities; ranging from mild inhibition to severe inhibition with oscillating "arms race" population dynamics. www.biorxiv.org/content/10.6...

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth! #protistsonsky 🧵

Hello everyone, take a look at my cool bugs from the Microbial Dark Matter phylum Saccharibacteria! These ultrasmall bacteria (in green) track down Actinobacteria hosts (not in green) and grow on the host cell envelope.

Exciting progress! In our new preprint, we show that episymbiont Saccharibacteria can directly modulate epithelial immunity—a big step in understanding how these elusive microbes interact with the human host. Kudos to Deepak Chouhan and our amazing collaborators! www.biorxiv.org/content/10.1...

New paper out! We searched for cargo across thousands of Type 11 Secretion Systems (T11SS) in Proteobacteria and uncovered 2,500+ predicted secreted proteins, including 6 novel cargo types, with experimental verification of a new surface lipoprotein, Pls. doi.org/10.1099/mgen.0.001406

Excited to share our new preprint on the detailed investigation of Type 4 pili in epibiont oral Saccharibacteria! Led by Alex Grossman from our lab, and with Jun Liu (Yale), Jeff McLean (UW) and Xuesong He. Check it out: biorxiv.org/content/10.1...
