I'm so sorry, friend. What happened? Are you OK? Hugs if you're in need of one or a few.

Awww. When guests come and bring goodies from our friendly neighbours upstairs. I miss the kindness of Canada. And I absolutely adore how excited they seem to be at the fact that Benito included them in the show.

And that was also one of the promises Lena made when I started here. She said: you'll learn to diagnose issues because the FSEs come from faraway places and we want them to have as much info about the issue they're coming to tackle as they can. And again, she was right.

Half joking. I'm. Toys r Us kid. I don't want to grow up. That, and the fact that the boss and sub-bosses always encourage curiosity and learning to troubleshoot like FSEs.

When you manage to fix an issue for a FSE in a couple of mins, without needing to restart a single thing. And the FSE says: that's very impressive. And I say, when I grow up I want to be like you 😁.

Happy Women in science day. On this day I am thinking of all my women science mentors and Rita Levi-Montalcini who did experiments in her bedroom in defiance of Mussolini’s ban on Jews in academic and professional careers while WWII raged around her.

I still got it. Doing a cryo insertion for the first time this year and it went beautifully. 22yrs and it's still there *chef's kiss.*

For those unaware about the significance of the light poles during the song El Apagón it’s because of the Puerto Rican power system and the constant black outs. There have been a lot of protests on the island over this.

Lastly, this one is for all of my fellow microscopists. Of all realms/modalities. A friend of mine wrote this a decade ago. She's a magnificent microscopist and I love her to pieces.

It's part of my job, young Padawan. Not only are we tool managers, we're finders of things, fixers of stuff, and sometimes we make magic happen 😬.

When one of your students asks that you keep an eye out for something and, so that you don't forget, send pics of when and where you found the something. Then they see you down the hallway and say thanks for finding the thing 😊

friends (and total strangers) ask how and/or why we do this. I always answer that we do serious microscopy in a very fun way. We know what it is to spend hours fine tuning or fib-milling a sample. We want to provide a safe (and hilarious) environment for all, saints included

On a lighter note, since Our Lady of Perpetual Stigmation was permanently relocated to Duffield Hall, we have a new Mary in the basement. For protection of the scopes, detectors and operators 😝
