Jul 12, 2026, 1:05 AM@MisuseCase my PhD advisor, Barbara Liskov, showed me some of the letters she had gotten from grad schools saying "we do not accept women into our graduate program"

And yeah, those grad schools were exceedingly dumb to reject her.

Technically her or any subclass.
In seriousness though, good lord. How many mediocre men did they accept.

Brian Marickmarick@mstdn.socialJul 28, 2026, 6:08 PM@dan @MisuseCase When my wife interviewed for a tenure track job at a vet school (early ‘90s), no fewer than two people asked her if she planned to have children. If so, she would be a bad risk for actually getting tenure (too much time spent not grinding).
When she entered vet school (later ‘80s), the class was largely male. Now it’s overwhelmingly female, even in farm animals (her specialty).

@dan @MisuseCase When it came to food animals, both other doctors and farmers thought she couldn’t do the job. How could a 125lb/57kg handle a bull? It would run her right over!
She had to explain that if a one-ton animal decides to go through you instead of around, it doesn’t matter if you’re a burly man twice her size: you *will* be moved out of the way, perhaps at a high speed.
Jul 28, 2026, 9:01 PM@marick brute force turns out to not be as useful with large animals than men think.
I had to give my horse eye drops for a year. We had a very friendly trusting relationship and it was so easy. And gentle.

@deepmud A lot of what Dawn did “on clinics” was teach vet students how to keep cows calm. For example, being herbivores, cows have something like a 135 degree field of vision. They don’t like things suddenly manifesting from their blind spot, so you should approach the cow from the front, put your hands on her, and nonaggressively move behind her – whereupon you stick your hand up her butt.
(Apparently that’s OK for the cow, I guess.)
- Brian Marickmarick@mstdn.socialJul 28, 2026, 11:48 PM
@deepmud However, another important thing to know was that if a bovine wants to smash you against a wall, it will, so your job is to go limp (so as to avoid some damage) and then fall down immediately (so the animal decides you’re no longer a threat and wanders away).

@marick horses are pretty sensitive and delicate. Also stupid compared to cows.
A cow caught in barbed wire will wait. A horse will kick itself to death.
Preventing being crushed is always a good idea! Some folks carry a wooden box. The box gives them space if crushing is on the menu. I've never had an animal try to crush me. But other things...

@deepmud Dawn was recruited by the University of Wisconsin vet school. It had advantages (beer in the student union! which is on a lake!), but she would have had to work on horses. She declined.
- Jul 29, 2026, 12:26 AM
@marick horses are dangerous. Although a heifer with horns is pretty scary. They KNOW they have horns. 😬
- Brian Marickmarick@mstdn.socialJul 31, 2026, 11:07 PM
@deepmud Dawn did hoof trims (or something) on rodeo bulls. They would come in a group. They were feisty. They had big horns and knew how to use them.
But she mainly worked on dairy cattle, which in the US don’t have horns. However, I remember when we were in the UK on our honeymoon we went to see a Celtic cross in the middle of a field. There was a big bull in the field. She marched straight on. I said, “Um… dear… bull?” She said, “Oh, he’s not mad” and marched on. I followed, and lived.

@marick she's more brave than I am. Those critters moods can change pretty quickly. 😬
- Brian Marickmarick@mstdn.socialAug 1, 2026, 11:41 PM
@deepmud I asked Dawn about it. She says that dangerous mood changes happen when the animal feels threatened. So the trick is to avoid making it feel threatened.
- Aug 2, 2026, 12:08 AM
@marick welllllll, yes...but the result of this mood change can get you put into orbit.
- Brian Marickmarick@mstdn.socialAug 2, 2026, 12:36 AM
@deepmud Dawn says the key skill is understanding when the mood of the animal starts changing, so that you can prepare.
She also informed me that llamas have killed people. An interesting bit is that they can charge a coyote, scoop it up with the head (they have really strong necks), fling it into the air, and then trample it when it hits the ground. https://en.wikipedia.org/wiki/Guard_llama (1/2)

Another fun fact is that, among the ruminants, llama milk is closest to human milk. https://pubmed.ncbi.nlm.nih.gov/8786255/ When she discovered that, I thought of a business producing high-end, high-price infant formula based on llama milk, but it turns out llamas are really hard to milk, even for baby llamas. (2/2)
@deepmud - Aug 2, 2026, 12:59 AM
@marick that's not the only good thing from llamas. Remember the antibodies they have? They may eventually help very sick people with things like covid
- Brian Marickmarick@mstdn.socialAug 2, 2026, 11:41 PM
@deepmud I don’t recall anything about antibodies. (Meaning Dawn may not have mentioned it to me.) I do know they have elliptical blood cells, supposedly better for low-oxygen environments.
- Aug 2, 2026, 11:45 PM
@marick just google "llama antibodies". You will be amazed!
- Brian Marickmarick@mstdn.socialAug 3, 2026, 10:09 PM
@deepmud Shocking that Dawn never told me about “nanobodies.” What other llama facts has she been hiding from me?
- Aug 3, 2026, 10:46 PM
@marick perhaps she doesn't know herself, and here is a grand opportunity to surprise her with your brilliance! 😃
I read medical research a couple of hours a day and during COVID, probably more.
I expect that right at this very moment, a drug company is trying to figure out how to patent those antibodies
- Brian Marickmarick@mstdn.socialAug 4, 2026, 3:41 AM
@deepmud She doesn’t remember ever learning about those antibodies.
Regarding https://hms.harvard.edu/news/no-llamas-required:
"Llamas are famously hard to draw blood from because of the anatomy of their neck and thickness of their skin. And they don’t cooperate. Using yeast seems much more pleasant and efficient.”
(Her attitude toward llamas seems to be llamas are to cows as cats are to dogs. Not horrible, but her favorite species are… her favorite species.)
- Aug 4, 2026, 3:49 AM
@marick fortunately, it appears that once some have been drawn from the unwilling llama, they can be reproduced outside of the critter.
Everyone gets to have favorite animals. I like dogs. And sheep.
- Aug 2, 2026, 1:00 AM
@marick donkeys too. I raised sheep. When I left, my sister got donkeys. They HATE dogs.
Of course it didn't help much that my sister also got a couple borzois. Really good at killing sheep. ☹️
- Brian Marickmarick@mstdn.socialJul 28, 2026, 11:53 PM
@deepmud
P.S. Dawn likes cows because they’re stoic. She thinks horses are like fussbol players: the slightest issue and they get all dramatic: I’ve been bumped! It’s the end of the world! Flop! Except that horses will prove their point by dying. - Jul 28, 2026, 11:50 PM
@marick horses are similar in that if you look like you're sneaking up on them, they try to run away. Gentle deliberate action seems better
