Different densities of liquids
a must reblog for the scientific community
it took me a solid minute to figure out what the hell they meant by die
The abstract concept of death is less dense than maple syrup but more dense than milk.
i thought this was a cocktail recipe diagram like hell yea turn me the fuck up

incidentally, this is still the single most hilarious anecdote re: apollo astronauts i have come across
Apollo 13 was halfway to the moon before Swigert realized he had not flied his income taxes and that he would be quite unable to do so before the April 15 deadline. The subject came up as scientist-astronaut Joe Kerwin was reading the Sunday morning news: “Today’s favorite pastime across the nation—Uh oh, have you guys completed your income tax?”
Swigert radioed, “How do I apply for an extension?” Mission control exploded with laughter. “It ain’t too funny, things happened real fast down there and I do need an extension. I’m really serious…”
“You’re breaking up the room down here,” Kerwin said. A few minutes later he assured Swigert that there wouldn’t be any problem: an automatic extension is granted to anyone who is out of the country at tax time.
HAHAHAHAHAHAHA!!!

Seriously, it kills me when I see people hold scientists up as pinnacles of logic and reason.
Because one time the professor I was interning for got punched in the face by another professor, because mine got the funding, and told the other professor his theory was stupid.
This same professor told me to throw rocks to scare the “stupid fucking crabs” into moving so we could count them properly.
SCIENCE
thank you
this is one of the best comments this post has recieved
I have witnessed:
Two professors hiding around a corner and snickering, “Shhh, here she comes!” While a female professor approached and, when she finally found them, she proceeded to scream while pointing from one to the other, “You! I called your office but you weren’t there! So I tried to call YOUR office to figure out where HE was but YOU weren’t there!”
Two grad students standing outside a closed and locked door yelling, “Come out of the damn office. You haven’t left for days. If you didn’t have a couch in there I’d be concerned as to where you were sleeping!”
A religious studies professor apologizing for being late to class because, “security stopped me because I’m dressed like a hobbit”
Watched a professor snort the results of my experiment to determine if I had the right final compound.
Two archeology professors toss priceless fossilized teeth back and forth in an attempt to figure out who is smarter by “guessing the type of tooth and species of animal before it lands”
Multiple fully degreed individuals throw dry ice at one another in an attempt to be first to use the lab/get that piece of equipment/or change the iPod song.
A genetics professor build furniture out of stacks of paper and planks of wood because she is that far behind in grading papers/responding. One of the impromptu furniture pieces housed a fish tank.
I could go on but I think that covers the larger portion of the insanity…
Every time it comes around on my dash, it gets better.
- I have had a professor buy a huge fuckoff bottle of rum during fieldwork in Costa Rica and let the undergrads get wasted because “you’re not underage in Costa Rica and we’ll be up all night with the bats anyway!”
- Same professor hung a bat from her headlamp and wore it as a decoration for an entire night.
- A whole swarm of older women - and these are women with PhDs and world-renown bat experts, the bigwigs - all, to a woman, go to the formal charity dinner at an international research symposium in Toronto in late October dressed in skimpy Batgirl costumes. Because Halloween was that weekend, you see.
- At a different conference, a professor get blackout drunk and pass out on the side of the road.
- “Yeah, we have to say we did it properly for the grant but to be really honest, Miracle-gro works better.”
- Teaching lab: we had liquid nitrogen for a demo, and after class the professor, the other TA, and I spent a good two hours freezing and breaking things in it.
a chemistry class begins with 30 students nine months later just six of us left sitting on tables dipping paper into contaminated chemicals to see what happens when we burn it teacher making idle suggestions while he marks our work
“go to the fume hood thing, yeah now put some potassium in chlorine” can i burn the results sir? “fuck it sure whatever its tainted anyway”
The prof I’m working for just asked me if I knew how to pick a lock, and when I responded “yes” she replied, “see, this is why I hire the former delinquents instead of the suck-ups. You’re actually useful.”
I then let her into her office.
“Security stopped me because I’m dressed like a hobbit.” I would bet anything this has happened to Dr. Medievalist.
Semi-related non-academic anecdote: The concert hall security guys tried to throw out our violone player in between performances this spring because they thought he was a homeless guy. Despite the fact that he was wearing concert black… and carrying a violone. There is no more obvious instrument.
One of my English Professors admitted that sometimes “you just have to do a soliloquy” and would phone up the main office of the department on the internal phoneline to recite a Shakespearean monologue at them. No greeting, no warning, just “To be or not to be”.
every time i read this stuff i think about how upset vulcans would be to meet earth’s greatest scientific minds
My viral genetics professor last semester had a stint where she insisted we smell our bacterial cultures, but then she came in one morning and told us not to do it anymore because she smelled one the previous night and sneezed/spat all over it
She left it in the incubator just to see what would happen

also sometimes if you just try it again with an adult palate because this is also a developmental issue little children are far more sensitive to bitter and metallic flavors it’s an evolutionary defense against poison

shit who the fuck was trying to poison their kids so much that we evolved into a species that kids need a mechanism against poison?????

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.

I don’t think they’d want to microwave him so hair dryer is really the only remaining option. That’s how I’d do it. badscienceshenanigans Do you have a sciency way to accomplish this task?Did they ever reveal how Captain America was thawed? Because I’m picturing a bunch of Shield agents with hair dryers and I don’t think that’s quite right.
Well, let’s see.
To thaw a 1.5 metric ton colossal squid frozen in a block of ice (the only way the fishermen who trawled the thing in could bring it home before it went bad), scientists put it in a big vat of brine just above 0 Celsius/32F. That allowed the fresh water to melt while still keeping the squid as cold as possible. Essential, since for a giant corpse with tentacles, certain parts are bound to thaw days before others and could become quite rotten before the rest comes out of the ice block if you’re not careful.
HOWEVER Captain America was still alive, which complicates things. On the other hand, even supersoldiers are significantly smaller than this record-setting colossal squid. This helps thaw logistics somewhat.
Much like the squid, Captain America would have to be kept at a consistent temperature throughout his body in order to be thawed successfully. If his extremities were to thaw more than a minute or two before his heart and lungs were thawed and reactivated, the tissue wouldn’t have any oxygen and would quickly die. What a shame to bring back Steve Rogers only to have him be the poster boy for gangrene. Brain tissue becoming metabolically active before the cardiovascular system began functioning would be even more disastrous— possible permanent brain damage.And the GH-325 project was born
To keep his temperature as equal as possible across his entire body, something like the squid brine or (more likely) an antifreeze solution would be used. Immerse the Capsicle in brine until the entire unit is within a degree or two of thawing* to begin Phase II.
*Note that due to presence of salts, fats, protein, etc, the freezing point of meat is actually 28-29F. Apologies to non-US readers, sadly I only work with American meat and don’t know the freezing point of corpses/beef in Sane Country Units. That being said, Steve Rogers is 100% American meat. Fahrenheit shall be considered the appropriate unit for this project.
At the thawing point, it’s important to consider life support functions. I don’t know how fast human tissue uses up oxygen at refrigerator-range temperatures, but I’m going to assume that the sooner you have oxygen circulating the better. A heart-lung machine would be needed to oxygenate and move the blood around for a while before the heart gets started back up.
Meanwhile, because Captain America’s last un-frozen moments were spent deep underwater, there may be decompression issues at play. Whatever gas bubbles may have been present in his tissue are currently frozen in place, but when he thaws they can move about and create embolisms —> the bends. Better put him in a hyperbaric chamber just in case.
Since Captain America regained consciousness in a recovery room rather than during the thaw process, it may be safe to assume that he was sedated and/or placed in a drug-induced coma during thaw.
So at this point we’ve got a giant bathtub of brine, a heart-lung machine, oxygen canisters, lots of drugs, plus all the necessary monitoring equipment all inside a hyperbaric chamber. After thawing the antifreeze bath could be replaced with gradually warming water or saline solution in order to bring Captain America back up to normal body temperature. So many machines! This is US medicine at its finest.
Forced warm air blowers (hairdryers) are needed after Captain America is fully thawed, organ systems are reactivated, and he is brought back to normal body temperature. At this point it becomes necessary to dry and style Captain America and put him in period-appropriate jammies to sleep it off in a vintage hospital room. If you think hearing the wrong baseball game tipped him off fast, you should see him wake up with bad hair.THIS IS THE BEST POST IN THE HISTORY OF EVERYTHING.
That being said, Steve Rogers is 100% American meat. Fahrenheit shall be considered the appropriate unit for this project.
#thats actually kind of fuckin hilarious bc they spent all that time making sure his temp was okay and he went through decompression and that he got enough oxygen#AND THEN THEY JUST HAPPEN TO CHOOSE THE ONE FUCKIN BASEBALL GAME THAT HE WAS AT#and he fUCKIN SPRINTS INTO MANHATTAN TRAFFIC#good job shield#good job

As the sun went down after the 1862 Battle of Shiloh during the Civil War, some soldiers noticed that their wounds were glowing a faint blue. Many men waited on the rainy, muddy Tennessee battlefield for two days that April, until medics could treat them. Once they were taken to field hospitals, the troops with glowing wounds were more likely to survive their injuries — and to get better faster. Thus the mysterious blue light was dubbed “Angel’s Glow.”

Scientists bred extremely sexually attractive male mosquitoes whose offspring are unable to breed. So these mosquitoes will hopefully dominate the mosquito gene pool, and in a generation or two, billions of mosquito larvae will be reproductive dead-ends.
Mosquitos deserve this for being little buggy assholes.
Mosquitos can be safely removed from the Ecosystem without any significant damage, whereas it can save countless people from disease.
how are we going to feed the fox bat?
In the lack of mosquitos in the fight for resources, the other insects in the area will rise in population, leaving the bats and frogs and spiders with much to eat still.
awesome, also i learned that fox bats eat fruit not insects
Coolio
Is no one going to address how scientists literally had to go “aight we have to make the most BANGIN mosquito possible. The SEXIEST thing these bloodsuckers have ever SEEN”
