The spread of the black death.

Poland

Poland, tell us your secret.

Poland is the old new Madagascar. 

If I remember correctly, Poland’s secret is that the jews where being blamed all over europe (as usual) as scapegoats for the black plague. Poland was the only place that accepted Jewish refugees, so pretty much all of them moved there. 
Now, one of the major causes of getting the plague was poor hygiene. This proved very effective for the plague because everyone threw their poop into the streets because there were no sewers, and literally no one bathed because it was against their religion. Unless they were jewish, who actually bathed relatively often. When all the jews moved to Poland, they brought bathing with them, and so the plague had little effect there.
Milan survived by quarantining its city and burning down the house of anyone showing early symptoms, with the entire family inside it. 

I reblogged this tons of times, but the Milan info is new.
Damn Italy, you scary.

Poland: “Hey, feeling a bit down? Have a quick wash! There, you see? All better”
Milan: “Aw, feeling a bit sick are we? BURN MOTHERFUCKER, BURN!!!!!”

Also, this might have something to do with it: from what I understand, O blood type is uncommonly… common in Poland. Something to do with large families in small villages and a LOT of intermarriage. The black plague was caused by a bacterium that produced, in its waste in the human body, wastes that very closely mimic the “B” marker sugars on red blood cells that keep the body from attacking its own immune system. Anyone who has a B blood type had an immune system that was naturally desensitized to the presence of the bacterium, and therefore was more prone to developing the disease. Anyone who had an O type was doubly lucky because the O blood type means the total absence of ANY markers, A or B, meaning that their bodys’ immune system would react quickly and violently against the invaders, while someone with an A may show symptoms and recover more slowly, while someone with B would have just died. Because O is a recessive blood type, it shows in higher numbers when more people who carry the recessive genes marry other people who also carry the recessive gene. Poland, which has a nearly 700 year history of being conquered by or partnering with every other nation in the surrounding area, was primarily an agricultural country, focused around smaller, farming communities where people were legally tied to, and required to work, “their” land, and so historically never “spread” their genes across a large area. The economy was, and had been, unstable for a very long period of time leading up to the plague, the government had been ineffective and had very little reach in comparison to the armies of the other countries around for a very very long time, and so its people largely remained in small communities where multiple generations of cross-familial inbreeding could have allowed for this more recessive gene to show up more frequently. Thus, there could be a higher percentage of O blood types in any region of the country, guaranteeing less spread of the illness and moving slower when it did manage to travel. Combine this with the fact that there were very few large, urban centers where the disease would thrive, and with the above facts, and you’ve got a lovely recipe for avoiding the plague.
Interestingly enough, as a result from the plague, the entirety of Europe now has a higher percentage of people with O blood type than any other region of the world. 

WHY IS THIS ALL SO COOL

When Tumblr teaches you more about the plague than 12 years of school ever did.

Just to throw a nod in, as a medieval historian, this is all credible, and is the leading theory as to the plagues effectiveness at this point. So. Enjoy your new knowledge!

Explosive pods launch seeds up to 20ft

Speaking of the evolutionary strategies of seeds, let’s all take a moment and appreciate this fantastic “exploding pod” maneuver, employed by a number of plants. Some varieties of Caigua (which I discussed last week), have to be harvested with goggles, just in case they pop!

Fantastic news for people who suffer regularly from migraine headaches. The FDA has just approved a wearable electrical stimulation device for sales in the United States — a headband that prevents the onset of migraines when worn for just 20 minutes each day.
A device like this is definitely long overdue. Some 10% of people worldwide suffer from migraines, a condition characterized by intense pulsing or throbbing pain in one area of the head, accompanied by nausea or vomiting and sensitivity to light and sound.
Developed by STX-Med in Beligum, Cefaly is a compact, portable, battery-powered, prescription device. It’s placed at the center of the forehead, just above the eyes, using a self-adhesive electrode. The headband then delivers transcutaneous electrical nerve stimulation (TENS) to the trigeminal nerve known to be involved in migraine headaches. The only known noticeable effect is a tingling or massaging sensation where the electrode is applied. It can only be used by people age 18 or older and should be used no more than once per day for 20 minutes. [x]

… huh.

i want a space tiara

Pusheen the cat making some chemistry.

That cat is not wearing safety goggles, he hasn’t even bothered to clean up that spilled solvent, and he is holding that Erlenmeyer flask way to close to his face.
Pusheen the Cat, more like Pusheen the limits of lab safety

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.(Source)

This is the coolest fucking thing ever. Science, man. Fucking science. Shit completely blows me away.
