My fiancee and I were discussing the worst metal to use to make armor, and the obvious answers are lead and gold, but she cunningly suggested mercury. Which is a fair point, but then I wondered if solid mercury is any good. Googling told me that the melting point of mercury is -38° c (-37° f), so first you get it really fucking cold. At that point, it turns out that mercury has a tensile strength of 1900 mpa, compared to lead’s 18 and steel’s ~500-940 (depending upon the kind of steel).
Now, I know that tensile strength is not necessarily the best measure of a material’s ability to function as armor, but I’m a liberal arts major and didn’t care to actually do that much more research before going straight to, “EVIL ICE DEMONS IN MERCURY ARMOR. THE PCS CAN’T LOOT IT BECAUSE WHEN THEY PUT IT ON IT MELTS AND KILLS THEM.”

god damn this is a QUILT ('late day shadows' by nancy messier)
THIS IS A QUILT?!?!?!?
ITS A FUCKING QUILT GUYS

this is literally correct. im so mad that i cant find it right now, maybe i will later, but a few months ago i read a paper that was a report on a survey of k-tape use by sports medicine people and physical therapists, and 70% of them reported that they knew/had observed that k-tape does absolutely nothing, but that athletes are so superstitious that the PTs would use the tape anyway because it improved performance via placebo. the majority of studies on k-tape are either inconclusive or a very definite "this does absolutely nothing".
i could see it maybe being useful specifically for proprioception due to pull sensation, and possibly in EDS patients where skin elasticity had something to do with muscle/joint stability and taping the surface provided more resistance. otherwise its less relevant to injury than prehistoric medical tatooing, at least the latter would involve microinjury with a needle, which we do have evidence to support lol
Oh oh lmao I have a similar thing I use sometimes for archery. It's this:
It's skintight as shown, very very tight, and against your skin each of those blue stripes is some kinda soft sticky material. Not adhesive, but it grabs the skin.
so speaking as a low level athlete in just the one sport, it's a totally proprioceptive thing. The pull on my skin gives a sort of awareness of where that body part is - elbow, shoulder blade. I *want* to really move my back (good for an archer) because the shirt is subtly pulling in that direction.
Thus the net effect is that the pulling sensations sorta ...hm...change what your brain expects to feel when you move, and just that little rattle onto a different mental track can be beneficial.
An example would be tapping on a different body part as a distraction when getting an injection - dreading that needle makes the pain Much worse, so v tapping elsewhere breaks up the dread and puts the needle pain back into perspective.
So for an athlete it's perhaps like.. tension makes everything hurt worse, but especially an injury. The PT cannot force the athlete to stay relaxed, but they can tape a dodgy joint after stretching/flexing/therapeutically manipulating it (the actual beneficial process), at which point the feel of the tape becomes a reminder to the athlete to be careful and precise when moving that body part. Stay focused on form, stay relaxed, and you'll be fine. And if they believe it..and fix whatever form error caused the injury.. they'll probably be fine.
KT tape: psychology you can see!
HI generally this function of k-tape is called cueing, either for postural (proprioceptive) and or isometric/specific muscles or muscle groups
The cool thing w k-tape (and most things, including nutrition bioavailability) is that the placebo affect is both real and proven so it's like. Rather than detracting from the efficacy, buying in/believing improves the treatment
Anyway compression sleeves/braces/garments/running tites/unitards do sort of the same thing (sensation on your body) to help you 1. Feel your body in space (proprioception) 2. Activate muscles you may be not using in concert with the movement like you want them to
Both of these models can be super helpful when correcting any favoring due to injury, or correcting poor form during exertion, same diff.
Beyond all of that, the superstition element - believing that it Will Help, also can do this really cool thing to help a person Trust their body, which can improve performance and pain sensations. Like, if you believe you're going about your sport or general business with this magic scaffolding in place to help things work right and not hurt and heal, generally it will do so. This is different from dissociating from the pain of an injury, because it invites the person to accept and move with and listen to the body sensations, because you have this weird tape on you and you can feel the weird tape on you
Ok end rant i think it's really cool how well k-tape can work and how Fully Believing practitioners think how it Must be Biomechanical this is Facts and Logic and Tendons but it's definitely mostly sensation and belief and listening to your body in space
Anyway yeah it's runes same diff

The above is from this article from The Guardian. The images are from MYA Network. The caption on their website reads:
Source: ‘When a sperm and egg get together, the body creates tissue in order to support the developing pregnancy. Here are photos of that tissue from 5-9 week pregnancies. This is called the gestational sac, and it’s like the “house” for the pregnancy. Inside this sac there are cells that have the potential to become a fetus but there is no visible embryo at this stage. We rinsed off the blood and menstrual lining (decidua) for these photographs.’
The published images sparked a lot of debate, leading to the story being picked up by other news outlets. For example:
Source: ‘Last week, the Guardian published images of pregnancy tissue after abortions in the first 10 weeks of pregnancy. The small size and appearance of the tissue were shocking to many. We have all absorbed, knowingly and unknowingly, the pervasive anti-abortion narrative that a pregnancy resembles a tiny baby starting in the earliest weeks. Though an early embryo can be seen under the magnification of ultrasound, it can take months for it to be perceptible to the naked eye.’
Source: ‘People have responded in disbelief, citing the (magnified) images they’ve seen on ultrasounds. […] ”Think of the illustrations on pregnancy and medical websites. The Mayo Clinic, one of the preeminent medical organizations in the country, shows week-by-week illustrations of embryonic and fetal development without any context of scale, like the rulers in the MYA photos.’
As stated in the article, whilst people talk about a ‘heartbeat’ at 6 weeks, there is no heart developed at this stage - only a group of cells that will become part of the heart.
Source: ‘But what exactly do we mean when we talk about a “fetal heartbeat” at six weeks of pregnancy? Although some people might picture a heart-shaped organ beating inside a fetus, this is not the case. Rather, at six weeks of pregnancy, an ultrasound can detect “a little flutter in the area that will become the future heart of the baby,” said Dr. Saima Aftab, medical director of the Fetal Care Center at Nicklaus Children’s Hospital in Miami. This flutter happens because the group of cells that will become the future “pacemaker” of the heart gain the capacity to fire electrical signals, she said.’
It should also be noted that the images show an embryo, not a fetus, until the 9th week.
Source: ‘In human pregnancies, a baby-to-be isn’t considered a fetus until the 9th week after conception, or week 11 after your last menstrual period (LMP).’
The co-founders of the MYA Network responded in a New York Times article.
Source: ‘Many people, even those who support abortion rights, did not believe the photos were accurate. Some insisted we had deliberately removed the embryos before taking the photos. The images weren’t consistent with those often seen in embryological textbooks, magnified on ultrasounds or used in anti-abortion propaganda; these enlarged images are not what you see with the naked eye after an abortion. A Stanford gynecologic pathologist has validated our photos, but many people could not believe the pictures were presented unaltered.
I’ve never seen pictures like this.
I got a marketing email from hobbycraft to say that they're now selling plush pumpkins ahead of halloween
so of course I went to the website, which led me to this delightful photo series showing the different sizes available:
I love and support this man and his pumpkin collection

No matter how progressive or well-read you are, there are always going to be moments in your life where somebody pushes back against something that's so culturally ingrained you never even considered it before. And you'll say "Huh, it never occurred to me to challenge this but you're right" and that doesn't mean you were "morally toxic" before, it means you're a non-omniscient human capable of growth.
okay just watched nimona and reread the novel this is the consensus:
if you want a feel good movie, more explicit gay and trans rep, and a more well realized high tech midieval world watch the nimona movie
if you want a darker tone and more morally gray characters, a really compelling twist/mystery, and a gay ass scientist side character read the nimona comic
the twitter thread the artist created after this was one of the best situations i have ever seen in my whole life:
Somebody give this ignoramus a piece of actual shark skin and tell him to rub his face with it, let him find out just how “smooth” sharks really are.
Somebody did. I use it as a pillowcase because it’s so smooth.
crystallotusfr
But buddy.
Shark skin feels exactly like sandpaper. It is made up of tiny teeth-like structures called placoid scales, also known as dermal denticles. These scales point towards the tail and help to reduce friction from surrounding water when the shark swims. … In the opposite direction, it feels very rough like sandpaper.
Buddy. It’s smooth. The link you sent me led to a website that described how smooth they are. I dunno, maybe you don’t know how to read?
this post is transcendent
You’re thinking of dolphins. Dolphins are the ones with smooth skin that feels like a rubber beach ball.

This potato works. Every. Fucking. Time.
Reblogging because it’s a damn potato and I want to encourage people to assume potatoes are magical.
w-what if potato is actually lucky
I got great news already but let's see how good it gets :)
