While the world’s eyes are on fashion’s biggest night, we’re turning ours to the garment, retail, and warehouse workers who keep the industry running. From true love found on the picket line to a free tailoring school out of a Brooklyn basement — meet the New Yorkers who make it all possible.

Do you want to see the "big picture" on climate change? Here it is. Emissions are on the left, and include CO2, CH4, N2O, and f-gases. Natural CO2 sinks (from healthy forests & oceans) are on the right. And carbon removal, what little there is, is on the right, too. All expressed as GWP100.

Genetic diversification of Pseudomonas fluorescens maintained by multi-niche selection within biofilms | Applied and Environmental Microbiology

Bacterial biofilms dominate microbial life; however, their evolutionary genetics remain incompletely understood. Extensive replication of biofilm selection experiments by secondary school students can...

Sharing the most significant work from my group, led by the @evolvingstem.bsky.social team. Come for the discoveries of how Pseudomonas adapts in biofilms, stay for the story of how they were discovered by thousands of young scientists in grades 9-12. 🧪🧫🧬🧵 www.biorxiv.org/content/10.1...

New preprint from my lab‼️ We describe how cations in the media remodel the Geobacter envelope for reciprocal control of cytochrome-loaded vesicles and conductive pili. Important phenomenon to understand discrepancies in the literature about the true nature of nanowires. doi.org/10.21203/rs....

Cation-driven envelope dynamics modulate outer membrane vesiculation and extracellular electron transfer in Geobacter

Geobacter bacteria use conductive pili and redox-active outer membrane vesicles to mediate metal transformations critical to the effectiveness of bioremediation and energy technologies. Mechanistic kn...

🧵 After years out of the field, I and my lab are again working on bacterial type IV pili. We have just posted our first preprints, and I'm excited to share what we have discovered. This shows Neisseria gonorrheae bacteria infecting a human epithelical cell. Here, you can see the pili in red. 1/
