A CROW TRIED TO GO IN OUR CLASSROOM AND HE HAD A PEN
yes hello i am here to learn geometries
That crow is more prepared than some of my students.
You’ve all just like, completely skipped over the possibility that this crow has seen people using pens in this room, found one, and is trying to return it. There’s been videos of crows picking up sweet wrappers and stuff and placing them in bins after seeing humans put their litter in bins. I really do believe that this crow is trying to return the pen and that is ADORABLE AS HELL.
THEY ARE SO SMART I LOVE THEM
Crows are thought to be self aware by some scientists. Its perfectly possible the crow wants to return the pen to humans. Knowing it belongs to humans.
Corvids. Who KNOWS. :)
Another cool crow deal: Once, when trying to assess if crows could reason and use tools, scientists had two crows who didn’t know each other each take a wire from a table (one was hooked, one was straight) and try to grab meat from a bottle with it. The crows could see each other, though they had separate bottles. Only the straight wire worked for this, so they hypothesized that if crows could reason, the second trial would have the two crows fighting over the straight wire. The second trial started and, to the surprise of the scientists, the two crows both went for the bent wire, one held it down and the other unbent it. They both got meat out of their bottles. They came to a peaceful solution without verbal communication. Crows are probably smarter than we are.

I’ve seen this photograph very frequently on tumblr and Facebook, always with the simple caption, “Ghost Heart”. What exactly is a ghost heart?
More than 3,200 people are on the waiting list for a heart transplant in the United States. Some won’t survive the wait. Last year, 340 died before a new heart was found.
The solution: Take a pig heart, soak it in an ingredient commonly found in shampoo and wash away the cells until you’re left with a protein scaffold that is to a heart what two-by-four framing is to a house.
Then inject that ghost heart, as it’s called, with hundreds of millions of blood or bone-marrow stem cells from a person who needs a heart transplant, place it in a bioreactor - a box with artificial lungs and tubes that pump oxygen and blood into it - and wait as the ghost heart begins to mature into a new, beating human heart.
Doris Taylor, director of regenerative medicine research at the Texas Heart Institute at St. Luke’s Episcopal Hospital in Houston, has been working on this— first using rat hearts, then pig hearts and human hearts - for years.
The process is called decellularization and it is a tissue engineering technique designed to strip out the cells from a donor organ, leaving nothing but connective tissue that used to hold the cells in place.
This scaffold of connective tissue - called a “ghost organ” for its pale and almost translucent appearance - can then be reseeded with a patient’s own cells, with the goal of regenerating an organ that can be transplanted into the patient without fear of tissue rejection.
This ghost heart is ready to be injected with a transplant recipient’s stem cells so a new heart - one that won’t be rejected - can be grown.
This is incredible.

|Women are told it is unfeminine and gross to have muscles and to cultivate strength, which in turn leads them to actively avoid doing things that will build muscles and strength, which then makes them even less capable of doing things that require strength, which the critics then use as proof of women’s inherent physical frailty. And so the cycle continues… |
And I always want to point out here: women, on average, possess more lower-body strength, while men, on average, possess more upper-body strength. There’s a lot of overlap and it isn’t always individually applicable, but that’s the generalization, averaging across the population.
But we SOCIALLY value upper-body strength, and upper-body muscles. So we construct women as weaker, because we refuse to measure them on the body parts where they may be stronger, we devalue those.
Lifting is mostly done with the legs. So women may be as good or better at heavy lifting as men. But we socially construct lifting as having to do with large, muscular arms and chests. You don’t really need powerful arms and chests to lift—you need powerful thighs, otherwise you’re gonna throw your back out. We actually lie about what makes a person strong and capable to favor men.
Push-up and pull-ups are upper-body strength exercises. So they’re socially valued. The military doesn’t tell you to do 20 squats as penance. No one is fucking impressed by all the squats you can do. Squats just sound stupid, hah, squats. We laugh at them because women might be better at them than men, on average. They’re worthless.
This stuff plays into all sorts of other body image problems, too. The body weight that’s regarded as ideal for women, for example, is really only achievable for individuals suffering from mild to moderate muscular atrophy. You literally can’t get there just by shedding fat - you also have to let your muscles waste away. We actually regard it as “normal” for a woman to be suffering from muscular atrophy.

The Gashadokuro are such a cool folklore concept.
My favorite thing is this idea that they somehow are able to silently stalk people despite being almost 100-foot tall skeletons, because no one looks up.
Gashadokuro aka the starving skeletons are the reanimated and combined bones of the victims of starvation. Up to a hundred feet tall, they are heralded by the sound of bells ringing in the ears of their victims. They reach down from above to capture people and bit their heads off. The Gashadokuro haunt the darkness after midnight.
phwoar that’s badass.

|Forget stardust—you are iron. Your blood is nothing but ferrous liquid. When you bleed, you reek of rust. It is iron that fills your heart and sits in your veins. And what is iron, really, unless it’s forged?|
You are iron.
And you are strong.

I’ll give Wheaton the benefit of the doubt that he didn’t see the original tweets Rothfuss was responding to…

The Sausage Duel of 1865,
In the mid 19th century Rudolph Virchow was a leading man of science and intellect in Europe. Among the many hats he wore he was a physician, biologist, anatomist, pathologist, and anthropologist. He was also deeply intertwined in German politics, being a social reformer and co-founder of the liberal party. In 1865 his greatest rival was none other than the great Prussian Chancellor Otto Von Bismarck. Virchow greatly criticized Bismarck’s policies, especially his excessive military budget. In 1865 Bismarck was so angered by Virchow’s opposition that he challenged him to a duel.
As challenged Virchow had the right to select what weapons would be used. Virchow was not a fighting man, however as a physician, biologist, and anatomist there was one weapon he was well acquainted with; science.
Virchow’s decision was that he and Bismarck would each consume a pork sausage which was randomly selected from two sausages; one regular sausage, and one sausage that was purposely infected with the larvae of a trichinella parasite. He who consumed the untainted sausage would be fine, however he who consumed the tainted sausage would suffer a terrible bout of the runs that could last for days. Other symptoms would include nausea, heartburn, dyspepsia, muscle weakness, swollen eyes, stroke, and neurological disorders. If left untreated death can occur within 4 -6 weeks.
Otto von Bismarck was a born soldier who probably hoped to die in glorified combat. However when it came to the possibility of dying a slow death while lying in a puddle of his own feces, Bismarck declined.

There is a British boutique ice cream company Lick Me I’m Delicious that have been working with Jellyfish bioluminescent proteins to produce ice cream that glows in the dark!
How it works? The proteins of the jellyfish are activated by calcium and due to a difference in pH levels the more neutral pH of the ice cream reacts with the higher acidity of your mouth causing the ice cream to glow in the dark when licked. The ice cream is entirely edible and is ~$220 per scoop!
