New paper out! Here's a puzzle: phototrophy, the ability to use light for energy, is one of life's great innovations. It evolved early and transformed the biosphere. But it evolved 2x. Why not just once, why not more? Our work suggests the answer is priority effects.

Yellowstone’s colors aren’t just minerals. They’re living microbes. Heat-loving bacteria and archaea form bands as water cools, each pigment tuned to temperature and light. What looks like abstract art is a thriving ecosystem shaped by extreme heat and chemistry.

Our lab is looking for a new PhD student to contribute to research on the early evolution of microbial life. Deadline coming-up soon on Monday 19th Jan.

Congratulations Eva!
🎉 Huge congratulations to Eva Stüeken for being awarded an @erc.europa.eu Consolidator Grant!

“Quantifying the limits of early life through the biogeochemical phosphorus redox cycle”

This win not only celebrates Eva 👏 but also highlights our school’s strength — 6 ERC grants in the last decade! 🚀

Great to see our perspective in print! Chad, Eva, and I suggest that geological and genomic records support the idea that Earth’s first oxygenated habitats formed on the seafloor, especially in shallow benthic settings along continental shelves

#geobiology #astrobiology @earthscista.bsky.social
⚒️ Perspective: The oxygenation of Earth's atmosphere about 2.45-2.30 billion years ago may have initiated in the oxidised bottom waters of marine shelves

I'm preparing to give a seminar on Friday, so let's dive into the uncomfortable etymology of 'SEMINAR'.

The Latin root is 'sēmen' & we're already seeing the problem?

It means "seed", with all its implications: plant & animal.

Have I been doing seminars wrong this whole time 😬?

This is the Groove-billed Ani (Crotophaga sulcirostris), and it's just straight up a dinosaur.

Like, I know *all* birds are technically avian dinosaurs, but my first thought looking at this guy is: dinosaur.

Worth watching and thinking about when we buy cod, haddock, halibut, sole, and prawns that are often trawled. I hope it says how they are caught on food labels so we can avoid bottom-trawled catches...
I will forever be haunted by this footage.

Trawling has only been filmed underwater a few times in documentary history, and never with such clarity.

What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives.

Despite covering 66% of Earth's surface, the DEEP ocean remains largely unexplored. @katycroffbell.bsky.social et al. are the first to document that, in decades of deep-sea exploration, humans have observed less than 0.001% of the deep seafloor!!!

One thing I wasn't ready for as a postdoc is how much the talks you give need to change. 😅

I think a good colloquium talk takes a lot of practice to get right, and it's so much more about presenting a "big picture" than just e.g. a paper you wrote/are writing.

It's so hard to get right! 🔭☄️🧪
