New York exceeds national breast cancer screening goal for second year
The screening estimates come from the New York State Behavioral Risk Factor Surveillance System.

BI-RADS 1 - negative. For now I can breathe. Last year I had my first MRI ever, a breast MRI. Higher risk runs in my family, as does colon cancer, sadly.

I've had chances other people my age didn't ... or couldn't. I thank the universe for my mom's health (and mine) and I honor those who are no longer in this realm, who are missed dearly, and who in many ways saved my life for than once.

Today I turned 45 (and my mom turned 77). I spent a quier day at home. Thinking of the craziness this last year has been. The new people I've met, the opportunities I've been given, the good fortune I've had.

I agree. The Nion (and before them, the VG) came to mind when I said the part about reciprocal TEM.

The concept that STEM is reciprocal to TEM is easier to explain with a Nion Column

And, if I could go back in time and hand a letter of encouragement to my younger self, I'd say: you will read about EM, my dear young self, and it'll blow your mind, and you will become a trained microscopist and work for a living teaching others what you've learned. I'm still amazed by this

Cryo Mariena @cryomariena.bsky.social · 02/04/2026
Things I say when I'm explaining TEM vs STEM: well, you can think of STEM as reciprocal TEM (always makes people lol). And: oh yeah, because STEM folks don't call it beam, they call it probe, and they don't list the whole beam, just the angle, in mrad 😝

Took a little bit of franken-doing, but, I have two used but in very used condition racks in the old dishwasher. Not more rusted racks. There was blood shed (mine, ofc). But, I did it!

It's really adorable when my son comes to me with a request that I fix something and, as much as I can, I'll give it my all. I remind him that we're all capable of doing great things, regardless of our sex/gender. I want him to know that his dad can cook, and I can fix things and vice versa.

Cryo Mariena @cryomariena.bsky.social · 25/03/2026
My son was very happy and surprised I'd been able to fix the car. His dad is a pretty good fixer. But when he can't figure something out, he'll bring it to me. I'll take a look and see if he missed something or if something is broken beyond repair

Those little things, taking stuff apart, finding out what's misbehaving, putting stuff back together, etc, it makes me happy. And I'm glad I've come across both a place and people who encourage and celebrate that kind of curiosity and abilities.

I found a quick tutorial on the same car, took some covers off, checked the chip, reseated a small antenna, put the covers back on, and boom, now it was running.

Then, my son had an RC car he got a couple of years ago. He wanted to play with it again, but we likely left some batteries in it, which went kaput. His dad did a bang up job cleaniner therminals, but it still didn't work.

Today, I again channeled my inner Lena. Twice. First, I'd ordered a replacement rack for the old dishwasher at home (orig one had some exposed rusty parts and I became concerned of metals contaminating our dishes). Part fit like a glove.

Cryo Mariena @cryomariena.bsky.social · 25/03/2026
But, I decided to channel my inner Lena (the goddess capable of fixing and diagnosing stuff in the lab/scope/detector/life), showed the boss and after packing it all up, the darn thing has maintained temps properly (AFAIK).

Turns out, we were getting a cooling error. And wouldn't you know it, one of the connections to the board (an ADC board) was not tighly bolted, as it should. Now, did I know exactly what I was doing? No. Was my colleague a wee skeptical. Sure.
