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. ;)

Cargo bike. tern GSD. Green one.

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”:

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.

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.

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

Black-and-white historical photograph showing a massive, billowing mushroom cloud rising high above a calm body of water. The cloud is dark and turbulent at the base, gradually lightening toward the top, with a thick stem connecting it to the surface. A small ship is visible in the foreground on the water, dwarfed by the enormous cloud, providing scale. The horizon is flat with distant land or trees faintly visible.
