Yes, we’ve calculated the physics of bending an iPhone in your skinny jeans.
Have you ever wondered why an ice pack relieves pain? Why should cold make the pain go away?
It works because a cold object activates fast fibers in your spinal cord, while pain travels up to your brain in slow fibers. So when you press a cold pack against a sore muscle your fast fibers beat out the slow ones. You feel cold not pain.

Lavoisier is having none of your shit.
Heeeey so fun fact: the woman in that painting is Lavoisier’s wife, Marie-Anne Pierrette Paulze, who not only acted as Lavoisier’s lab assistant but also translated English and Latin texts into French so he could read them. But she didn’t just translate, she pointed out errors in the chemistry in some of the texts. Her observations of these errors convinced Lavoisier to study combustion, which led to his discovery of oxygen. She was also critical to the publication of Lavoisier’s Elementary Treatise on Chemistry in 1789. She kept strict records of every experiment they conducted together and drew detailed diagrams of all their equipment. She also threw amazing parties and invited all the brightest minds in science so her husband could pick their brains. After Lavoisier was guillotined she secured all of his notebooks and equipment for posterity.
In short: NOBODY KICKS MADAME LAVOISIER OUT OF THE LAB.
Also, a side note: My historian husband-to-be pointed some things out to me about this painting. Notice that Madame Lavoisier is looking at the viewer, and all the light is on her, while Lavoisier himself is physically smaller than her, in shadow, and looking up to her in reverence. This isn’t a candid photograph- all of these choices are deliberate. The painting isn’t of Lavoisier- Madame Lavoisier is meant to be the central subject.
I can just imagine Lavoisier telling all his colleagues that his wife is really the one with all the clever ideas, and them patting him on the back and telling him he’s sweet for saying so.
I LOVE IT
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.
Excuse me but we can’t just kill pigs to save human lives. That is wrong.

"soak it in an ingredient commonly found in shampoos" What the fuck am I putting in my hair?!
^ hahahaha, yes. this is a good point.
If you look at the ingredients list and it’s a bunch of words you don’t even know… neither does your body (x)
Just like if you break apples and grapefruit down into their chemical components, I’m willing to bet that most people wouldn’t recognize the “ingredients” either. It’s a bunch of words you don’t even know:
Don’t use these scare tactics - Chemicals aren’t inherently bad. Literally everything is made up chemicals. Trust me, your body knows what niacin is. It knows how to digest fructose and calcium sulfate. Even if you only consume the most basic and “real” foods that are pulled directly off the vine, you’re still ingesting a series of chemical compounds that you probably can’t pronounce. That’s okay.
EVERYTHING IS CHEMICALS
Sloshing is a problem with which anyone who has carried an overly full cup is familiar. Because of their freedom to flow and conform to any shape, fluids can shift their shape and center of mass drastically when transported. The issue can be especially pronounced in a partially-filled tank. The sloshing of water in a tank on a pick-up truck, for example, can be enough to rock the entire vehicle. One way to deal with sloshing is actively-controlled vibration damping - in other words, making small movements in response to the sloshing to keep the amplitude small. This is exactly the kind of compensation we do when carrying a mug of coffee without spilling. (Image credit: Bosch Rexroth; source)
Q: What do you call an extinct flying reptile that loves the smell of rain?
I think I’m becoming obsessed with the fluid dynamics of iced coffee and milk.
Joe - here’s one for you from last month! Keep forgetting to post it. In the interest of science, this was cold-brewed coffee and the cream is half and half.
If everyone could just go ahead and post their coffee/milk fluid dynamics photos, that would be super :)
can I link an instagram video?!
You can link whatever you want! Someone should start a whole tumblr for coffee fluid dynamics photos.
GIVE THEM TO MEEEE
This build was originally inspired by the Lego X-Pod sets. While trying to find a use for the pod itself, I realized that it was very close to a deep petri dish. I used a planetary gear system to allow both coarse and fine adjustment of the objective “lens”. A little more tinkering and I connected the focus to a magnifying glass and fiber optic light in the eyepiece, so adjusting the focus knobs would actually bring the writing on a Lego stud in and out of focus.

But how are they supposed to turn the knobs with those useless U-shaped hands?!?

I love how this post is like “Oh, clean up some of the nastiest, hard to clean shit with coke!” but doesn’t mention “Hey, you actually ingest this stuff that can clean CORRODED CAR BATTERIES.”
Heyyy this is because when you put carbon dioxide to make the carbonated water, you get carbonic acid. Carbonic acid varies in how much the pH is, especially in the different coke products. Strong enough to dissolve rust but not steel or any of the metals mentioned here.
But here’s the thing, carbonic acid is not one of the 6 strong acids. You know what is one of those? Hydrocholric acid. You know where you naturally secrete hydrocholric acid? Your stomach. Hydrochloric acid is some nasty stuff and WILL eat away at a screw if allowed to soak long enough. If you ever got just drop of a diluted solution on your skin in chem lab, then you can see where that would happen very easily.
The stronger acid wins. Your tummy is fine when you drink coke. Your tummy makes acid strong enough to fuck that corroded battery up. It can handle a can of coke. Please don’t swallow a screw or something to test this tho, please.
THANK YOU, KEEPEROFTHEHENS. I’m tired of people acting like soda is the worst possible thing you can put in your body. Yeah, I know it isn’t good for me, but I wish people would stop using scare tactics to stop people from drinking whatever the hell they want to drink.
Yay hydrophobic clothing!
They need to understand what evolution is about. Many of them don’t. I was truly shocked to be told by two separate religious leaders in this country [the U.S.] a few weeks ago—they both said something to the effect that, “I’ll believe in evolution when I see a tailed monkey give birth to a human.”
That is staggering ignorance of what evolutionary science is about; if they think that’s what evolutionists believe, no wonder they’re skeptical of it. How can a civilized country have adult people in positions of leadership who know so stunningly little about the leading biological concept?
This is….so comforting….
