Next up from our lab - a ring nuclease with a novel fold which cleaves all cOA species involved in Type III CRISPR defence. It's also found in plasmid and phage genomes, where it presumably functions as an anti-CRISPR.

Watching a short film on the dangers of climate change in the Cloud Forest, Singapore. Wondering if this would still be shown in the USA?

It was a pleasure to act as Laureator for the award of an honorary degree to Prof Dame Anne Glover @uniofstandrews.bsky.social last week. Anne was my lecturer when I was an undergraduate - an inspriational scientist

It's that time of year when you get the THE Global Academic Reputation Survey invite and ponder: "Do I vote for my own institution?"

For 2024, I'm going to use this flow-chart to prioritise requests to review papers. At the end of the year I'll let you know the numbers in each category. I thought of adding an "am I being paid?" question, but what's the point?
