The moon isn’t a planet you dumbfuck

the moon isn’t on there, fyi

that’s mercury, venus, earth, mars, jupiter, saturn, uranus, neptune, and pluto

Pluto isn’t a planet you dumbfuck

Viva la Pluto, motherfucker.

One day, we’re going to have one of those, “well in my day” stories, and we’re all gonna say, “Well in my day, Pluto was a planet!”

Also, Viva la Pluto, motherfucker.

Girls pose by a jail that recalls the witch trials of 1692 in Salem, Massachusetts. Photo taken in 1945.

I recently learned that the water in Salem was contaminated with the fungus from which LSD is derived and a legitimate theory for the whole thing is that everyone in the town was tripping balls 

This might be the greatest thing ive ever seen on the internet

We did a whole massive thing on this in history. I believe the fungus in question is called Ergot and it’s terrifying. It makes your muscles spasm so when they had seizures that was the reason, not because they were possessed. One woman had to be strapped to her bed, she was seizing so bad. And, like ‘theybuildbuildings’ said, it had the same effects as LSD; as soon as you touch it, let alone consume it, it messes with your entire system. The worst thing is, you practically always had a bad trip. Many complained about bugs crawling under their skin or monsters emerging from the shadows to scratch and bite at them until they were screaming. It was a horrendous thing and the worst part is, Ergot is still around. It grows on crops and, if your wheat isn’t properly treated, it can be eaten and you’ll most likely experience the same as the women of Salem. 

god i love history

This is hella cool and almost correct… 

The effects on the people of Salem were probably from consuming bread with the fungus in it, not from contaminated water. And apparently rye is way more commonly affected than wheat. In fact, often the members of the clergy were able to afford nicer bread made from wheat and thus were not as commonly affected.

You don’t go on a spasm-y trip just by touching it. You have to consume it for weeks, which results in chronic poisoning. ( If you stop eating it early enough, you may recover. So when people suffering from these “demonic possessions” took refuge in churches and stopped eating low-grade rye bread they were sometimes miraculously healed. 

More interesting facts:

Ergot poisoning can result in convulsions & hallucinations, or it can cause gangrene, depending on which group of active alkaloids are present. (Horrifying, either way.) It killed a lot of people in Europe in the Middle Ages. 

In Europe, often there was a strong correlation between wet summers (which provide ideal conditions for ergot) and reports of witchcraft/ possession. And in Norway and Scotland, records of witch persecution are only found in areas where rye was grown and used to make bread.

And I just learned right now that one author dude translated the word “Beowulf” as “barley-wolf” which could indicate a connection to ergot. The LSD-like effects could be a valid explanation for stories of Old Norse warriors going into the a sort of trancelike battle rage.

(this is exactly the kind of stuff my herbology medicinal plants class is about, it’s so cool omfg. we had a lecture on ergot last week.)

WHAT KIND OF WIZARD FISH IS THIS

DUDE THATS A BABY KAIJU

pew, pew!

SCIENCE SIDE OF TUMBLR URGENT

YOU CALLED!?

This fish is not actually spitting bioluminescent spit…it’s spitting out its bioluminescent food! Some clever scientist has put some bioluminescent ostracods in a tank with some little fish. When agitated, these ostracods (tiny shirmpthings) secrete chemicals that, when combined, emit light.

Why?

You’re seeing why right here. Just before the fish spits it out, those light chemicals are filling up the belly of the fish. Now, it isn’t poisonous or anything…but the fish wants NOTHING TO DO WITH IT because the fish has predators too

So yeah, if you’re a little fish and suddenly you’re FREAKING GLOWING, your lifespan has just gotten a lot shorter. 

As soon as the fish realizes that there’s light emanating from its belly, it pukes out the glowing juices (and the little shrimp). You can actually see the ostracod in this gif swimming away down toward the bottom of the tank happy as a clam…or a shrimp. 

Evolution is AWESOME.

This is why you gotta follow SciShow on Tumblr.

A sensational breakthrough: the first bionic hand that can feel

The first bionic hand that allows an amputee to feel what they are touching will be transplanted later this year in a pioneering operation that could introduce a new generation of artificial limbs with sensory perception.

The patient is an unnamed man in his 20s living in Rome who lost the lower part of his arm following an accident, said Silvestro Micera of the Ecole Polytechnique Federale de Lausanne in Switzerland.

The wiring of his new bionic hand will be connected to the patient’s nervous system with the hope that the man will be able to control the movements of the hand as well as receiving touch signals from the hand’s skin sensors.

Dr Micera said that the hand will be attached directly to the patient’s nervous system via electrodes clipped onto two of the arm’s main nerves, the median and the ulnar nerves.

This should allow the man to control the hand by his thoughts, as well as receiving sensory signals to his brain from the hand’s sensors. It will effectively provide a fast, bidirectional flow of information between the man’s nervous system and the prosthetic hand.

“This is real progress, real hope for amputees. It will be the first prosthetic that will provide real-time sensory feedback for grasping,” Dr Micera said.

“It is clear that the more sensory feeling an amputee has, the more likely you will get full acceptance of that limb,” he told the American Association for the Advancement of Science meeting in Boston.

“We could be on the cusp of providing new and more effective clinical solutions to amputees in the next year,” he said.

DO YOU PEOPLE EVEN REALIZE HOW AWESOME THIS IS???

TO DO THIS MEANS WE CAN FINALLY STITCH AXONS (LONG PART OF NEURON OR NERVE CELL THAT TRANSPORTS SIGNALS FROM JUNCTIONS BACK TO THE BRAIN) BACK TOGETHER

DO YOU EVEN UNDERSTAND HOW IMPOSSIBLE THAT WAS? TO ALIGN THE DAMAGED AXONS BACK TOGETHER WAS IMPOSSIBLE 

WITH THIS BREAK THROUGH YOU COULD EVENTUALLY WORK UP TO GIVING THE ABILITY TO WALK AND MOVE AGAIN TO THOSE WHO CUT THEIR SPINAL CORD IN AN ACCIDENT THIS IS BEAUTIFUL

THIS. IS. AMAZING.

""but that book character has blue/grey/light eyes so obviously they’re white!!"" ://///

Yes, goddamnit

















(Reminder that light eyes and blonde hair can be caused by conditions, such as Waardenburg Syndrome and albinism, but they are still real people that can (and should) be represented in media and such)

And also I can add that I have news for y’all, people can be black and naturally blonde







And literally people from ANY KIND can be a redheadand have freackles and such


















So please, stop pretending only white people can have those characteristics, jfc, it’s sofucking annoying.

Boom de yada

Just to add on - While race is a very, very, very significant issue, race as we know it is a social construct. When you acknowledge that all people on earth have veeeery little genetic variation in the scope of things, it’s much easier to break oneself from the training of “only white people have this, only black people have that, only asian people have this trait, etc”

the funny thing ist though, even if a character is described as having dark skin, dark hair and brown eyes, theyre still being cast as white

It’s also worth noting that the fact that a black person has blonde or red hair doesn’t necessarily mean they’ve got a white ancestor kicking around in their family tree. Recent genetic studies suggest that the gene that codes for blonde hair in black African populations is completely different from the gene that codes for blonde hair in white European populations, and that blond hair among Aboriginal Australian populations is connected to yet a third gene. The same trait has independently arisen at least three times in humanity’s generic history, and only one of those cases is linked with light skin per se.

(Interestingly, this also means that the widspread belief that blonde hair is part of a complex of adaptations to low-sunlight regions is probably false, since populations that live in the sunniest parts of the world have their own blonde-hair mutations unrelated to the European one.)
