Came across this a few months ago. In-patient had d-dimer ordered on a Saturday round by on-call staff. Positive result not followed up. Monday morning the patient appears in the OR for a 6-hr thoracolumbar decompression-fusion.
GREAT.

New rule: If you order the D-Dimer, you have to interpret the D-Dimer

Anesthesia publications on GLP-1 RAs and delayed gastric emptying started to appear mid-2023.
These findings likely reflect the continued use of GLP-1 RAs into the perioperative period.

This appeared on the BBC News today, showing the increase in solar electric generation in the UK.
Not sure who produced it, but genuinely think this is a genius piece of scientific communication - the construct and choice of colour scale is near-perfect.
Chapeau!

Calvin and Hobbes was one of three comics that shaped my sense of humour and self.
The Far Side covered absurdism and science; Bloom County covered politics; and Calvin reconnected me to my imagination and foretold my role as father.

Knives Out: Wake Up Dead Man is just a really elaborate Rick Roll.
This is true and I was the only one on set excited about it (and playing the song on my phone to blank stares)
Just watched the new Knives Out and I think it's really important you know that the scene in the Seminary's Gym is filmed in the same place Rick Astley filmed the music video for Never Gonna Give You Up.
I saw the window tracery and immediately made my friends pause the film so I could tell them.

Painted cycle lanes are the non-smoking sections of today's urban landscape.
Both recognize a problem and the harms it causes, but are designed without the will or imagination required to implement a real solution.

What does it take to move 1000 people? Smart infrastructure supporting choices that don’t take up so much space (or produce so much emissions/pollution, cost so much public money etc).
