Good news! The most overused word of 2013 is clearly in decline. Epic became synonymous with dudebro culture thanks to web phenomena like Epic Meal Time and epic fail, leading marketers to pounce on the word in hopes of reaching the demographic. That explains why CNN has it twice on their front page this morning, like a dad trying to connect with his son.
This video was made by the University of Utah Brain Institute to teach medical students about what a brain looks and feels like before it gets preserved in formalin and takes on the texture of a hard rubber ball.
The big takeaway message: Your brain is seriously squishy. So squishy, in fact, that a finger can dent it. As professor Suzanne Stensaas explains, this is one of the reasons why cerebrospinal fluid is so important. Your brain has to float in that fluid. If it didn't, it would come to rest against the side of your hard skull and quickly end up deformed.
The crazy part about NASA's Asteroid Initiative isn't so much the part where we land human beings on an asteroid. That's cool and all, sure. But the bit that precedes it is actually a little bit more mindblowing. To make that landing work, we'll first have to send out robotic spacecraft to essentially capture an asteroid and tow it into a stable orbit around the Moon. Yeah. Seriously. Welcome to living in the future, dudes.
I've been describing this Slate piece as the most awesome thing I really should not have read at 38 weeks pregnant. For decades, doctors thought that a pregnant woman whose heart stopped had pretty much no chance of survival. After trying to resuscitate her, attention would shift to rescuing the baby. But recent research suggests a better solution: Spend less time trying to get the mother's heart pumping again. Not only does it give the infants a better shot at survival, it also, insanely enough, saves more mothers. Turns out, once somebody removes the other human from your body, your failed heart will often just start pumping again on its own.
"The Festival of Bad Ad Hoc Hypotheses (BAH!) is a celebration of well-argued and thoroughly researched but completely incorrect evolutionary theory" — in other words, it's a festival dedicated to the ability to bullshit in a plausibly scientific way. And it sounds fantastic. If you're in Boston October 6th, you should totally go. But you'll need a ticket. They're $5 for MIT students, $10 for non-students.
Scientists using radio waves to estimate the thickness of the ice sheet that covers Greenland found a canyon — more than 2600 feet deep and almost 500 miles long — buried under the ice. Longer than the Grand Canyon, the Greenland canyon hasn't ever been seen by humans. It was probably last completely uncovered 4 million years ago.
Last night, my husband and I went to the Minnesota State Fair and stumbled upon a demonstration of a linotype machine, a semi-automated, mechanical printing system that was used by newspapers and magazines (and basically everything else) from the end of the 19th century through the 1970s. It's a completely mesmerizing piece of equipment. An operator types out a line of text and the machine responds by collecting molds that match each letter and fitting them together. Then, it fills the mold with molten metal and dumps out the freshly minted block, ready for the printer ... before automatically re-racking all the letter molds so they're ready for the next line of text.
Besides magnetism, there's another thing that the Insane Clown Posse was on-track in categorizing as a mind-blowing mystery — Why do Shaggy 2 Dope's kids look just like him? As with the magnets, this is another situation where the obvious answer (it's genetics!) masks a much more complicated issue that science hasn't totally figured out yet. At Pacific Standard, Michael White explains why genetics is still messing with our heads, almost 150 years after Mendel:
The problem: most of the genetic differences discovered have only a very small effect. And when you add up all those effects, the result can’t possibly explain the full influence of our genes on those traits. For example, researchers have identified hundreds of DNA differences between people that influence the very strongly heritable trait of human height, but the total effect of those differences added together explains only about 10 percent of the genetic influence on height. In other words, we still can’t explain why tall parents have tall children.
Scientists have named this discrepancy the “missing heritability,” and they’ve spent the last half-decade trying to find it.
Now, to temper this awesome news with a bit of harsh reality: Nova Delphini is not a supernova and it's not going to be as bright an object as you're probably imagining. Discover's Corey Powell has instructions for how to spot it (it probably won't be super obvious, especially if you're in a city) and galleries of photos, just in case you can't see it yourself.
Four foot, four inches in circumference. "She believes her voluminous hair may have grown even bigger, but she cannot reveal its size until Guinness take an official measurement." [Video Link, Daily Mail]
Behold, the common housefly — Musca domestica. You know it as a connoisseur of both sugar water and disgusting crap (literally), but this animal is also, deep inside, a sensitive arteest. Human artist John Knuth figured out how to help M. domestica express its passionate, aesthetic side in a series of paintings that exploit basic housefly behavior.
Houseflies "taste" with their feet. Their appendages are covered with chemically sensitive hairs, called chemoreceptors, which means that houseflies spend a lot of time walking around on top of their food. In addition, they can only eat liquids. If they encounter something delicious-but-solid they must first liquify it by slathering it in digestive juices. Finally, because they have to not-exactly-vomit on solid food so often, houseflies also need a lot of liquid in their diet to remain sufficiently hydrated. And that, as this pregnant lady can tell you, means the flies are also using the bathroom fairly frequently.
Knuth puts these rather disgusting traits to work in the name of art by supplying his flies with ample quantities of colored sugar water and lining their cages with canvas. The flies track the colors all over the canvas, in the form of brightly hued footprints, digestive juices, and excrement. The results are much more attractive than you might guess.
Guidebook for the Scientific Traveler, published in 2010 and written by Duane Nickel, promises to be a tour guide to chemistry and physics points of interest all across the United States. (Thanks Tim Heffernan!)
Known affectionately as Bertha, this tunnel boring machine has the widest diameter of any boring machine ever built; 57.5 feet. It's being used to dig a highway tunnel under downtown Seattle and it just arrived there today after being shipped from Japan.
Like the people cheering at about :25 into this video, I'm a sucker for dramatic explosions. This one comes from Texas, where the transportation department blew up an old bridge in the city of Marble Falls on March 17th. Also, apparently, it's warm enough in Texas that multiple gentlemen could watch a bridge explode from the comfort of their jet skis.
