Prof of Chemistry at the University of Oxford. loves Ruben sandwiches and complex chemical systems. Canadian, father, synthesis, chirality
Watching an old (stupid) movie- its weird how much John Larroquette and David Williams look alike - if it wasn’t for the 25 years I would’ve thought they were the same person
Another Oxford cargo bike theft!! Mine is customised by having a lot of stickers and nail varnish my kids did on it. Stolen on Meadow Lane at 18.30 today locked to a Sheffield stand. Please LMK if anyone sees it for sale. Probably in Cambridge. ;)
I wish Calgary would embrace other themed costume weeks like it does Stampede. There should be a week where we dress up like magicians. Another where everyone is now a zebra. It would be good.

“Putting a perfect GPA in reach of so many students perversely deters them from taking classes that could threaten it,” Harvard professor Joshua Greene argues. “We should liberate our students from the tyranny of the impeccable transcript”:

For more than a decade, a seventh-grade math teacher used technology in his classroom. This year, he took the Chromebooks away—and quickly learned how the computers were holding his students back, Jenny Anderson writes.
What Happened After a Teacher Ditched Screens
Why one early adopter of computers in classrooms has decided to toss them.

AI detection systems - its AI, why would anyone concerned about AI trust these?
I agree 100% with Steven Vickers that authors will be falsely accused of using AI in the coming years. In particular, authors like myself whose works were stolen to train AI systems are at risk. When we write in our own unique styles, AI trained on us will quite likely flag us as using AI.

I can't be the only one who is made /uncomfortable/ by the way that razor clams burrow into sand, right? The final moments of this video by Kate Crump on the Oregon coastline are sort of the crowning glory of horror. 😬 But how does this even work? Let's talk about bivalve mobility (if we must).
Congratulations to the prize-winners from our recent Early Career Researcher Symposium and Poster Event in Organic Chemistry & Chemical Biology, sponsored by Pharmaron. Pictured are poster prize winners Stanley Oppong, Oskar Ford, Sara Borghi, Nandini Guzman and Maddison Lovell.
Banbury gets this, and we get.. more lab space. CITY CENTRE PLAYGROUND WHEN, @oxfordcitycouncil.bsky.social ?! Maybe we should #bemoreBanbury Bit of imagination?!
The site of Debenhams in Banbury’s Castle Quay is to be transformed into a 50,000 square foot multi zone indoor playground for all ages including a ninja style assault course, slide city and a soft play for children. It is set to open in Summer 2026. castlequay.co.uk/whats-on/fun...

Without naming your job, tell me something you say over and over again at work. Is it sterics or electronics??? Why not both?!?!
A colleague asked me if anyone can identify this glassblowing tool. From the collection of a distinguished long gone colleague. Happy to hear thoughts.

Ok here it is - out of 44 FDA approvals this year, 31 are small molecules (70%), 26 of those are oral drugs (84%), 22 of them are chiral (71%). This is the largest number and percentage of chiral FDA approved molecules in a single year. Fitusiran is not a small molecule, bonus.
Come be my colleague @ucdchemistry.bsky.social! We're currently looking for an organic chemist (broadly defined) to start as a permanent (i.e., tenured) assistant professor. Job reference (www.ucd.ie/workatucd/jo...) is 019237. Due date Feb. 27, 2026 Reach out if you have questions!
On Dec. 6, 1917 at 8:45 a.m., the Imo and Mont-Blanc (which was packed with explosives) collided in Halifax Harbour. At 9:05 a.m., the Mont-Blanc exploded. The 2.9 kiloton blast levelled most of Halifax, killed 1,700 and injured 9,000. This is the story. 📸 LAC 🧵 1/12

The chemotypes within FDA approvals so far this year are quite diverse. Most of the 2025 small molecule approvals are chiral with four covalent electrophiles.
any suggestions for a equivalent reagent for Na/Hg?
