We had a great fall crash course on fluorescence microscopy. Thank you to all our participants and instructors.

Day 1 of the Fall Crash Course on Fluorescence Microscopy is nearly done. We've had a great start, lots of questions, and are ramping up for tomorrow! #microscopy #fluorescence

Registration closes Friday at noon! Are you in South-Western Ontario and interested in fluorescence microscopy? If so, we are offering a 2-day course on designing, implementing and analysing microscopy experiments. Visit our website for more information: micrographiauwo.ca/cc2025/ #microscopy

This is insane. 13 years ago we bought a million dollar #microscope to do this type of super-resolution imaging. Today, all you need is a smartphone and a few hundred bucks of off-the-shelf components 🤯

Direct single-molecule detection and super-resolution imaging with a low-cost portable smartphone-based microscope - Nature Communications
Loretan and colleagues present a low-cost smartphone-based microscope capable of detecting single-molecule fluorescence. This approach opens doors to personalised and widely distributed applications in diagnostics, biosensing, and science education.

✅ Mullet
✅ Skates
✅ Padding
✅ Uniform (slightly big)
✅ New stick

Time for some 🏒

(also, it's 33°C today for some reason)

My 10 y/o officially has a mullet. And I'm afraid to say that it is glorious.

#Micorscopy community, does anyone know where I can order this type of bottle from? Or even what the proper name is for them?

I'm excited to announce my labs newest paper in which we identify GATA2 as a driver of a stem cell-like phenotype of atherosclerotic plaque macrophages which promote the development of disease. #macrophages #atheroscerlosis

GATA2 Induces a Stem Cell-Like Transcriptional Program in Macrophages That Promotes an Atherogenic Phenotype
The upregulation of GATA2 in response to pro-atherosclerotic stimuli induces a stem cell-like phenotype in macrophages that promotes disease progression.

Some things never change. My son has joined his first 🏒 team (along with 2 of his friends) and has gotten his first jock strap...so just like when I was a kid, the first thing the three of them did was see how hard they could kick eachother in the crotch.

This is a bit of a long shot, but does anyone know of a source for the OT-IIZ T cell hybridoma (immortalized OT-II T cells)? I've been unable to find a cell repository that carries it. #Immunosky

Time to get this long weekend started!

I'm two days into my holiday. Made a new (turtle) friend, saw a big boat, and saved my soul by drinking some beer.

We had a great #garlic harvest this year!

Coffee, a novel, and a bit of shade - pretty much a perfect interlude for today's brewday (brew kettles in the back).

The backyard pizza oven is one of my favorite things. But today may not have been the right day to cook in front of an open fire. #pizza #heatwave

Some homebrewing fun - opening a sour beer that I carbonated a little more than is normal. #homebrewing #sourbeer

I have seen things 👀

...I have seen...my optometrist.
