  • Friday marked 5 years of sobriety from alcohol for me, which was nice. Then on Saturday I went to my city’s pride parade. I asked a friend to come with me, and another friend if they wanted to play a round of disc golf afterwards, but both cancelled. This usually means I wallow in self-pity, but instead I got geared up in my gayest outfit, and enjoyed the festival anyway! it was like 100 degrees, but I was proud to see so many happy people having a great time in one of the most welcoming, accepting environments ever.




  • When I was in medical school, I had my lab scheduled before lunch time. Which meant that I went straight from dissecting people, to eating. I’d get a big salad, and asked the cafeteria workers to heat up the slices of chicken breast I’d get on the salad. They didn’t like that I asked for it heated up, because it was extra work for them. But after they told me they wouldn’t do it anymore, I said “man, I was just dissecting a person, and this chicken is just way too similar looking to human for me to eat cold, ya feel me?” They ended up heating my chicken.




  • Another article that can’t even bother linking to the actual research

    Astronauts have an unusually high rate of kidney stone formation, with 1-year post-flight astronauts experiencing incidence rates of 2–7 times that of pre-flight estimates, and in-flight risk estimated to be double that again5. This is of mission critical significance, one Soviet in-flight renal stone episode nearly caused a mission termination due to the severe symptoms, but was relieved by spontaneous stone passage by the cosmonaut just before an urgent deorbit was initiated

    It has been demonstrated that spaceflight associated changes in urinary biochemistry favour kidney stone formation

    the kidney is an exquisitely radiation sensitive organ; it is the dose limiting organ in abdominal radiotherapy

    Our data robustly and orthogonally supports tubular remodelling occurring in microgravity with and without GCR (Galactic Cosmic Radiation). This is highly likely to have functional consequences, as tubular remodelling does in other scenarios39.

    Renal remodelling in microgravity (possibly related to the cephalad fluid shift) may therefore be a primary event that causes subsequent dysregulation of serum and urine electrolyte homeostasis. This is supported by the prompt return to baseline of humans on return to terrestrial gravity.

    Sounds like GCR is a big concern to Renal functionality due to it’s sensitivity to radiation, but they don’t think it’s the main driver of astronauts subsequent renal dysfunction. Interesting stuff.








  • Morton Thiokol

    you mean Allan McDonald?

    Interestingly enough:

    The focus of the commission’s investigation shifted to the booster rocket O-rings, and the concerns and efforts of McDonald and his engineers to stop the launch which were ignored by NASA officials. McDonald’s comments to the commission led to him temporarily losing his position with Morton Thiokol, being demoted.

    The presidential commission was alarmed at Morton Thiokol’s decision to punish McDonald and introduced a joint resolution that threatened to prevent Morton Thiokol from receiving further contracts from NASA. Given the commission’s threat, Morton Thiokol promoted McDonald to vice president and tasked him with improving the rocket joints that failed during Challenger’s launch.

    Perhaps the U.S. govt needs to step in again to right the ship at boeing. Well, I’m being coy, of course the U.S. gov’t has to step up and do something. Companies should never be some sacred cow that we’re afraid of upsetting.
