Tony Hansberry II was a ninth-grader. The new sewing technique he has developed helps to to reduce the risk of complications and simplifies the hysterectomy procedure for less seasoned surgeons.His goal is to attend medical school and become a neurosurgeon. For Tony, it all began in school. He attends Darnell-Cookman School of the Medical Arts, a medical magnet school for middle and high schoolstudents. As part of its integrated medical curriculum, students receive medical instruction, but are also exposed to medical professionals who demonstrate advanced surgical techniques with specialized equipment. His lead medical teacher, Angela TenBroeck, told the Florida Times-Union that Hansberry is a typical student, but is way ahead of his classmates when it comes to surgical skills “I would put him up against a first year medical student. He is an outstanding young man,” she said.
During his summer break, Tony volunteered at the University of Florida’s Center for Simulation Education and Safety Research (CSESaR) at Shands Jacksonville Hospital. He was supervised by Dr. Brent Siebel, a urogynecologist, and Bruce Nappi, the administrative director. Together they worked with Tony exploring the mannequins and simulation equipment that physicians and nurses use in training. He became quite interested in invasive surgery and using laparoscopic instruments. As the story goes, one day an obstetrics and gynecology professor asked the group to help him figure out why no one was using a particular surgical device, called an endostitch for hysterectomy suturing procedures. This long medical device has clamps on the end, but Tony used the instrument in a new way allowing for vertical suturing, instead of the traditional horizontal method. After two days, Tony had perfected and tested his new technique. He soon developed a science fair project comparing the suturing times of the vertical endostitch closures vs the horizontal closures using a conventional needle driver instrument.
His results showed he was able to stitch three times faster using this new method. Use of this inventive technique may lead to shorter surgical times and improved patient treatment.

I bet there are labels like this all over Avengers tower
If something is ‘old as fuck’ then it’s about 1.2 billion years old because that’s when life evolved sexual reproduction.
However, if something is “old as balls” it’s only about 65 million years old, when placental mammals began to evolve proper testicles.
Here are some basics on herd immunity, and here is some more technical research if you’re interested in the details!
If you’ve ever heard my rants about vaccination, you know it’s a major topic with me. Because hey, I’m one of these immunosuppressed people this comic talks about, so it’s a bit of a sensitive subject. (“Oh, I’m sorry, you don’t like getting vaccinated? I don’t like having three month long respiratory infections because you gave me the freaking flu, but I guess you don’t care about that”)
Essentially, Ellen and her wonderful character Katherine have just said it better than I ever could—and using Shaun of the Dead references, too!!! It’s all about herd immunity—getting vaccinated isn’t just about your own health, it’s about the health—and non-zombification—of the entire human race.
Awesome explanation.
Meet Jedidah Isler
She is the first black woman to earn a PhD in astronomy from Yale University.
As much as she loves astrophysics, Isler is very aware of the barriers that still remain for young women of color going into science. “It’s unfortunately an as-yet-unresolved part of the experience,” she says. She works to lower those barriers, and also to improve the atmosphere for women of color once they become scientists, noting that “they often face unique barriers as a result of their position at the intersection of race and gender, not to mention class, socioeconomic status and potentially a number of other identities.”
While Isler recounts instances of overt racial and gender discrimination that are jaw-dropping, she says more subtle things happen more often. Isler works with the American Astronomical Society’s commission on the status of minorities in astronomy.
She also believes that while things will improve as more women of color enter the sciences, institutions must lead the way toward creating positive environments for diverse student populations. That is why she is active in directly engaging young women of color: for example participating in a career exploration panel on behalf of the Women’s Commission out of the City of Syracuse Mayor’s Office, meeting with high-achieving middle-school girls. She is also on the board of trustees at the Museum of Science and Technology (MOST).
“Whether I like it or not, I’m one of only a few women of color in this position,” she says. “Addressing these larger issues of access to education and career exploration are just as important as the astrophysical work that I do.”

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.
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.Do you have a sciency way to accomplish this task?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 bornTo 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.
i guess the real question is how can you not like tesla
he thought women would eventually rule the world because we’re the dominant sex
he liked pigeons
he was a vegetarian
he was a babe
he was shy
he hated edison
he’s perfect
Yup, as long as you’re ok with that time he went bonkers and tried to build a death ray.
Are you serious the death ray was the best part
Never not reblog Tesla.
The death ray was the best part Obvs.
Oh, like YOU wouldn’t build a death ray given the chance.
I’ll have you know that now Tesla is totally Doctor Horrible in my head, now.
happy birthday, cap
BOOB GRAB! 😀

What if it bites me and it dies?
that means you’re poisonous. jesus christ, nate, learn to read.
What if it bites itself and I die?
It’s voodoo.
What if it bites me and someone else dies?
That’s correlation, not causation.
what if we bite each other and neither of us die
that’s kinky
oh my god
The Doorway Effect: Why your brain won’t let you remember what you were doing before you came in here
I work in a lab, and the way our lab is set up, there are two adjacent rooms, connected by both an outer hallway and an inner doorway. I do most of my work on one side, but every time I walk over to the other side to grab a reagent or a box of tips, I completely forget what I was after. This leads to a lot of me standing with one hand on the freezer door and grumbling, “What the hell was I doing?” It got to where all I had to say was “Every damn time” and my labmate would laugh. Finally, when I explained to our new labmate why I was standing next to his bench with a glazed look in my eyes, he was able to shed some light. “Oh, yeah, that’s a well-documented phenomenon,” he said. “Doorways wipe your memory.”
Being the gung-ho new science blogger that I am, I decided to investigate. And it’s true! Well, doorways don’t literally wipe your memory. But they do encourage your brain to dump whatever it was working on before and get ready to do something new. In one study, participants played a video game in which they had to carry an object either across a room or into a new room. Then they were given a quiz. Participants who passed through a doorway had more trouble remembering what they were doing. It didn’t matter if the video game display was made smaller and less immersive, or if the participants performed the same task in an actual room—the results were similar. Returning to the room where they had begun the task didn’t help: even context didn’t serve to jog folks’ memories.
The researchers wrote that their results are consistent with what they call an “event model” of memory. They say the brain keeps some information ready to go at all times, but it can’t hold on to everything. So it takes advantage of what the researchers called an “event boundary,” like a doorway into a new room, to dump the old info and start over. Apparently my brain doesn’t care that my timer has seconds to go—if I have to go into the other room, I’m doing something new, and can’t remember that my previous task was antibody, idiot, you needed antibody.
Read more at Scientific American, or the original study.
I finally learned why I completely space when I cross to the other side of the lab, and that I’m apparently not alone.
