In the nearly 13 years I’ve lived in Québec City (capital of Québec, the province that nearly separated from Canada thirty years ago) I had never, ever received a flyer from a local business advertising their Canadian-ness … until today. It’s weird times in Québec.
A real estate flyer with Canadian flags and a statement in French stating the company is Canadian and founded in 1913.

29/Yes, the US has a trade deficit with Canada. It’s because Canada sells the US a lot of oil and electricity—at a discount, mind you. economics.td.com/ca-canada-us...
A chart showing how, since about 2008, if you remove oil & gas from the equation, the US has a trade surplus with Canada.

5/I haven’t been able to attend the last two SMDM meetings because I was recovering from a broken leg and couldn’t travel solo yet. I was really excited about going this year, for many reasons.

But I can’t do it.

It’s just appalling. All of it.
Josh Marshall @joshtpm.bsky.social Termination notices going out this afternoon to more than 300 employees of the National Cancer Institute. Access likely ends today. Four weeks paid leave and that’s it. Strong power move for Team Cancer. Dr Tom Frieden @drtomfrieden.bsky.social The abrupt terminations of more than 1,000 employees, including new Epidemic Intelligence Officers, across CDC are deeply disturbing. For more than 70 years, EIS officers have served on America’s front line as its disease detectives, ready at a moment’s notice to respond to emerging outbreaks. Rep. Greg Stanton @repgregstanton.bsky.social The termination of 850 Indian Health Service physicians, nurses, and dentists will have a grave impact on access to care for millions of Native Americans. Upholding our treaty obligations is not optional. John Washington @jwashing.bsky.social Venezuelan mom pulled over for driving too slowly in Tucson. Two of her four kids were in the backseat. State troopers called Border Patrol. That's the last her family and community has heard from them. It's been 3 days.

I was probably best known for this viral tweet. Old screencaps of it still circulate regularly.
A tweet responding to: what’s something that seems obvious within your profession but the general public seems to misunderstand? My answer was: That $35 that scientific journals charge you to read a paper goes 100% to the publisher, 0% to the authors. If you just email us to ask for our papers, we are allowed to send them to you for free, and we will be genuinely delighted to do so.
