I accidentally clicked on stuff for you without realizing it the other day and just spent awhile scrolling and totally lost. Who are all these people that I haven’t followed? 😅
People describe shoebill storks as being scary or ugly birds and always use one image to make their point. When in every other photo they look like this
Neanderthal tools might look relatively simple, but new research shows that Homo neanderthalensis devised a method of generating a glue derived from birch tar to hold them together about 200,000 years ago—and it was tough. This ancient superglue made bone and stone adhere to wood, was waterproof, and didn’t decompose. The tar was also used a hundred thousand years before modern humans came up with anything synthetic.
After studying ancient tools that carry residue from this glue, a team of researchers from the Eberhard Karls University of Tübingen and other institutions in Germany found evidence that this glue wasn’t just the original tar; it had been transformed in some way. This raises the question of what was involved in that transformation.
To see how Neanderthals could have converted birch tar into glue, the research team tried several different processing methods. Any suspicion that the tar came directly from birch trees didn’t hold up because birch trees do not secrete anything that worked as an adhesive. So what kind of processing was needed?
Each technique that was tested used only materials that Neanderthals would have been able to access. Condensation methods, which involve burning birch bark on cobblestones so the tar can condense on the stones, were the simplest techniques used—allowing bark to burn above ground doesn’t really involve much thought beyond lighting a fire.
The other methods involved a recipe where the bark was not actually burned but heated after being placed underground. Two of these methods involved burying rolls of bark in embers that would heat them and produce tar. The third method would distill the tar. Because there were no ceramics during the Stone Age, sediment was shaped into upper and lower structures to hold the bark, which was then heated by fire. Distilled tar would slowly drip from the upper structure into the lower one.
The resulting tars were all put through chemical and molecular analysis, as well as micro-CT scans, to determine which came closest to the residue on actual Neanderthal tools. Tars synthesized underground were closest to the residue on the original artifacts.
“[Neanderthals] distilled tar in an intentionally created underground environment that restricted oxygen flow and remained invisible during the process,” the researchers wrote. “This degree of complexity is unlikely to have been invented spontaneously.”

Omg hiiiii! *regurgitates blood into your mouth because you had a bad hunt and we have a grooming relationship and we’re both girls and also vampire bats* uwu!!
People don’t like to admit it bcs cringe or w/e but Homestuck really did revolutionize the webcomic as a storytelling medium and I am endlessly frustrated that before webcomic artists could really stretch our legs fucking webtoonz swooped in, set a new, more restrictive standard, and then monetized and monopolized the ever living fuck out of the concept of The Webcomic until it drove away anyone who couldn’t be a professional quality manga artist for free, and now the only webcomics that actually feel like spiritual successors to Homestuck are so obscure they’re basically cult classics that you have to beg people to read.
Like it’s just so wild to be in high school and see Homestuck be like “we’re using like fifteen different artistic mediums to tell this story bcs we can” and be really fucking inspired by that, only to grow up and see basically every webcomic ever have to conform to One Single Standard or fucking perish.
Actually, I realized my real point here: we all need to make our art weirder. Please make weird art. I want more stuff like Prequel Adventure and 17776 and MyHouse.wad and I want it now. Capitalism thrives on conformity. We must be weird at all costs.
This is why fat shaming can have tragic consequences.
If this sort of weight-based medical bias happens to any of y'all, politely tell the doctor (during your visit) that you want them to write in your file that they are refusing ordering tests for you because of your current weight. This usually causes them to order the test anyways because they do NOT want a malpractice suit. Remember: You want to make a paper trail to hold them accountable.
