The real high-risk science is “Let 1,000 flowers bloom“ science, which spreads money around to many many different individuals to pursue their best ideas. 🧪

Interesting how much regional variation there is. I wonder if the higher hesitancy in Ontario vs Alberta is due to different approaches to public health messaging (local vs provincial) last year.

This was an FOI request from advocay group Safe Parkside - exactly the kind of information Ford wants to hide.

Yeah. Maybe a bad year? Need another couple datapoints. Most clinical positives in youth.

The trials that quietly changed our lives Testing claims matters more than ever in an age of misinformation, overconfident assertions and unsubstantiated opinions

My article in the Financial Times about my book. It includes a wonderful randomised trial of beer glasses (which you might unknowingly have been part of if you bought a pint in some British pubs c.1998)

The COVID-19 pandemic continues to keep pressure on the Canadian healthcare system. Almost half of hospitalizations related to vaccine-preventable respiratory diseases in 2024 were due to COVID-19. Average cost just for those patients was ~0.75B.

What is the ‘overview effect’? We may be watching it play out right now in space | CNN The Artemis astronauts’ reflections echo a long described shift in perspective that occurs when humans are given the chance to view Earth from space.

The Overview Effect. All politicians including heads of state should have mandatory VR sessions. e.g, youtu.be/G9oruV3wyf0?...

Pretty sure that’s a comment.

Influenza B still going strong in Ottawa wastewater. Clinical surveillance is a few weeks behind.

On this day 6(!) years ago, a sample was collected in Ottawa that would go on to become the first SARS-CoV-2 datapoint on the chart! Joined a couple of years later with Inf A, Inf B, RSV, MPOX.🎂
