Metastatic embolus from breast adenocarcinoma in the lungs
cancer cells are usually very metamorphic, which you can tell by the different shapes of the nuclei in this embolus. i love how you can see the metastasis inside a vessel perfectly in this picture!

Hey... what the fuck???
So I read the article, and this is super cool. Basically what happened is that they let a drop of butyl alcohol out from a syringe onto the surface of another liquid, and it just... hung out there? For a very significant amount of time, too. In the past, this type of "droplet levitation" has only lasted a few milliseconds max, but this droplet was staying levitated without any external forces applied for tens of minutes.
The reason this happens is because of Solutocapilllary convection, which as far as I can tell essentially boosts the surface tension of that one spot in the underlying liquid using vapor molecules, so that the butyl alcohol molecule can't sink in.
Also, the reason why I specified that the reason this was cool is because it was done without external forces is that APPARENTLY we've been able to levitate things using sound waves since like... the 1930s. And it makes sense that you can do that, in principle, but it still looks absolutely wild to see.
Slime Molds and Intelligence
Okay, despite going into a biology related field, I only just learned about slime molds, and hang on, because it gets WILD.
This guy in the picture is called Physarum polycephalum, one of the more commonly studied types of slime mold. It was originally thought to be a fungus, though we now know it to actually be a type of protist (a sort of catch-all group for any eukaryotic organism that isn't a plant, animal, or a fungus). As protists go, it's pretty smart. It is very good at finding the most efficient way to get to a food source, or multiple food sources. In fact, placing a slime mold on a map with food sources at all of the major cities can give a pretty good idea of an efficient transportation system. Here is a slime mold growing over a map of Tokyo compared to the actual Tokyo railway system:
Pretty good, right? Though they don't have eyes, ears, or noses, the slime molds are able to sense objects at a distance kind of like a spider using tiny differences in tension and vibrations to sense a fly caught in its web. Instead of a spiderweb, though, this organism relies on proteins called TRP channels. The slime mold can then make decisions about where it wants to grow. In one experiment, a slime mold was put in a petri dish with one glass disk on one side and 3 glass disks on the other side. Even though the disks weren't a food source, the slime mold chose to grow towards and investigate the side with 3 disks over 70% of the time.
Even more impressive is that these organisms have some sense of time. If you blow cold air on them every hour on the hour, they'll start to shrink away in anticipation when before the air hits after only 3 hours.
Now, I hear you say, this is cool and all, but like, I can do all those things too. The slime mold isn't special...
To which I would like to point out that you have a significant advantage over the slime mold, seeing as you have a brain.
Yeah, these protists can accomplish all of the things I just talked about, and they just... don't have any sort of neural architecture whatsoever? They don't even have brain cells, let alone the structures that should allow them to process sensory information and make decisions because of it. Nothing that should give them a sense of time. Scientists literally have no idea how this thing is able to "think'. But however it does, it is sure to be a form of cognition that is completely and utterly different from anything that we're familiar with.
not to be positive on main but sometimes things really are ok. sometimes you really will be happy and safe and warm. sometimes you really will be giggly and blushy and full of love. sometimes the night is chilly and your home is cozy and your tea is perfectly steeped and your phone lights up with a message from someone you love. sometimes life really is quite lovely.
is there a name for this
@plaguedocboi why this happen
At extreme depths, life must be watery and blobby because hard parts would be crushed by the pressure. The bibby is mostly squish and cartilage with minimal bones so they look soft and cute!
Therocephalians were a group of synapsids very closely related to – or possibly even ancestral to – the lineage leading to modern mammals. They were a diverse and successful group of carnivores during the latter half of the Permian, but suffered massively during the "Great Dying" mass extinction, with only a handful of representatives making it a few million years into the Triassic.
Tetracynodon darti was one of these rare Triassic therocephalian survivors, living in what is now South Africa around 251 million years ago. Only about 25cm long (~10"), it had slender limbs and strong claws that suggest it was a scratch-digger. Its long snout was lined with pointed teeth, and it was probably an active predator hunting by snapping its jaws at fast-moving prey like insects and smaller vertebrates.
Its combination of small size, burrow-digging habits, and unspecialized diet may be the reason it scraped through the Great Dying when most of its relatives didn't – but unfortunately it seems to have been a "dead clade walking", disappearing only a short way into early Triassic deposits.

Unless you were a tech at NASA back in the day, when one time some hydrogen a) escaped in a particular building, and b) caught on fire. This was extremely difficult because hydrogen does NOT burn on the visible spectrum humans evolved to see (and flee). Rather, it technically does, but it’s so pale that in practice, no one could see it. Additionally, pure hydrogen burns without smoke and with so little ambient heat that you can’t really sense it till you walk into it. So, per the lore, for a few days all the techs in that building just walked around brandishing brooms in front of them like lances. If your broom lit on fire, congrats! You have located more burning hydrogen! Do not proceed!
oh my god it's real and it was LITERALLY called "the broom method" holy shit
Fun fact: my dad, after being a surgeon for 25 years, no longer has fingerprints. The sponge he uses to wash his hands several times a day is so harsh that it’s rubbed off his fingerprints throughout the years. Sometimes he can’t get into our building because the biometric uses a fingerprint scanner 😭
