Let’s stare into the far red 🏮. A stunning tour-de-force of high-resolution #CryoEM by Gio, Bill, & company reveals how the machinery of photosynthesis redshifts itself so cyanobacteria can live on far red light, deep in the cracks of rocks or under microbial mats. #PlantScience 🧪 🧶🧬 🌾 🔬 🌍
Have you ever looked at the night sky and wondered if there’s a chlorophyll f in the reaction centre of Photosystem I from far-red light adapted cyanobacteria? 🦠
Well, we did (don’t judge) and the work that followed is now out as a First Release in @science.org

Locating the missing chlorophylls f in far-red photosystem I
The discovery of chlorophyll f-containing photosystems, with their long-wavelength photochemistry, represented a distinct, low-energy paradigm for oxygenic photosynthesis. Structural studies on chloro...

New preprint out from the team! Master‘s student extraordinaire Julia Bauer stumbled across a Ca transporter needed for endospore maturation in Solibacillus 🧫🔬 www.biorxiv.org/content/10.1...
Decoding the functional role of the calcium ATPase YloB in microbially induced calcite precipitation and sporulation in Solibacillus silvestris
Calcium homeostasis is essential for bacterial physiology, yet its regulation and role in specialized processes such as microbially induced calcite precipitation (MICP) and sporulation remain poorly u...

Possibly outing myself as the biggest nerd ever here but what a massive day for Ryan Sharpe, Oakville, Ontario, Canada appearing on both US Jeopardy and UK University Challenge!!

So happy our pre-print on daptomycin mechanism of action is now out! Here, we present three main findings: i) daptomycin does not form large membrane pores in either B. subtilis or S. aureus, (1/3)
