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 😬?

How did life begin, and why does it matter? Scientists are tracing early microbial life—from LUCA to multicellularity—to unlock insights for biotech, climate science and even space exploration.

Excited to have seen and heard (via bat detector) noctule bats around Kinessburn and Cockshaugh park in St. Andrews yesterday evening! One of the UK's largest species at the size of a blackbird! Big thanks to Dr. Sasha Newar and the NVC Group for organizing our sunset bat tour

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! 🔭☄️🧪

Happy to see this out @NatComm
We found that the unicellular coastal cyanobacterium Cyanothece sp uses sodium energetics rather than the typical proton energetics to fix N2. Sodium energetics likely is more widespread and affects the global nitrogen cycle.
