Taxidermy Tuesday, an interesting Bobcat taxidermy.
The bobcat is crepuscular. It keeps on the move from three hours before sunset until about midnight, and then again from before dawn until three hours after sunrise.

Polymer Filter Quickly Makes Water Safe To Drink
It’s a thirsty world out there. But with much of the globe’s drinking supply unimproved by treatment systems that can remove animal waste, bacteria, viruses, and chemicals, a clean sip of water is too often a luxury.
Many researchers and inventors are looking for cheaper and faster ways to get clean drinking water to people who lack it. On the industrial scale, people are refining filtration membranes by using advanced materials like graphene to make more efficient potable water supplies. Others are using architecture to make rain-harvesting buildings. For individuals, one designer has made a solar power distiller to turn saltwater fresh. These are just a few examples of a lot of brainpower going in to help around 780 million people who have limited access to clean water.
Now a Swiss Federal Institute of Technology in Zurich (ETHZ) team says they have developed a novel personal filtration tool that will contribute to the solution. Using a three-stage system that includes an advanced polymer membrane, they say the device, called DrinkPure, works so quickly that it can filter up to a liter of water a minute.

Accidents, flaking, losses
Louis Thomas Jérôme Auzoux (1797-1880 ), a French doctor, confronted with the difficulty of learning the human anatomy, designed an anatomical diagram in pasteboard that could be disassembled. The various organs were molded so that they could be mass produced. He presented his (invention to the Medical Academy in 1822. Thousands of these models were then sold all over the world, during more than one hundred and fifty years, training generations of doctors.
Me: *scrolling down tumblr dashboard*
Me: THERE’S A NEW DW TEASER?! WHY DIDN’T I KNOW ABOUT THIS?!
Me: *waves arms around head in excitement* squuuuuueeeeeeeeeeeeeeeeeeee!!!!!
Me: *watching teaser*
Me: OoOooOOohhh, new TARDIS interior! Finally some decent lighting! And bookshelves too!!
Me: What is Twelve doing on the roof of the TARDIS?
Me: I don’t care! I’m excited! *waves arms around head in excitement*
Crow: CROW YES!
It’s actually impossible to measure how many fucks a corvid give because there is no device sensitive enough to register such a tiny amount.
science/animal side of tumblr… explain to me the birb thing
Tail Pulling is a behavior noted in many corvids. The practical application is to create a distraction that will allow the birb to make off with the target’s food. Imagine being in the lunch room and a large fellow has a Twinkie you covet. You can’t just take it from him because he’ll defend his Twinkie. But if you thwap him on the back of his neck and then dash around to snag the Twinkie while he investigates, you stand a decent chance of enjoying spongey goodness. This is basically that in birb form.
Except corvids don’t only do this as a distraction. Sometimes they seem to just being doing it to mess with other animals/birbs. But to use my lunch room analogy, there are times you might thwap someone sneakily on the back of the neck just for amusement. Primates exhibit behavior that appears to be just be annoying other animals for amusement. Given how intelligent crows are, its not unlikely that this is a manifestation of an innate desire to just fuck with someone else for the fun of it. Such as this from the link above:
THANK YOU FOR THE BIRB KNOWLEDGE
Corvids are the best birds.
During the 2011 and 2012 migration seasons, University of Missouri researchers monitored mallard ducks with new remote satellite tracking technology, marking the first time ducks have been tracked closely during the entirety of their migration from Canada to the American Midwest and back. The research revealed that mallards use public and private wetland conservation areas extensively as they travel hundreds of miles across the continent. Dylan Kesler, an assistant professor of fisheries and wildlife in the College of Agriculture, Food and Natural Resources at MU, says these findings illustrate the importance of maintaining protected wetland areas.
"We have lost nearly 90 percent of wetland areas in Missouri in the last century and 50 percent of wetlands across the country since the early 1800s," Kesler said. "This loss has affected migratory bird populations and migration timing and routes. Our research shows the importance of these wetland areas to maintain healthy populations of migratory birds and other species, especially in an age of budget cuts for government programs protecting these few remaining wetland areas. If we don’t maintain these wildlife preserves it will put dozens, if not hundreds, of wildlife species in danger."
Codariocalyx motorius, known as the telegraph plant or semaphore plant, is a tropical Asian shrub, one of a few plants capable of rapid movement. This plant is famous for its movement of small, lateral leaflets at speeds rapid enough to be perceivable with the naked eye. This is a strategy to maximise light by tracking the sun. Each leaf is equipped with a hinge that permits it to be moved to receive more sunlight, but the weight of these leaves means the plant must expend a lot of energy in moving it. To optimise its movement, each large leaf has two small leaflets at its base. These move constantly along an elliptical path, sampling the intensity of sunlight, and directing the large leaf to the area of most intensity. (Wikipedia)

Forty years ago, a vast molten cavity known as the Darvaza crater – nicknamed the “door to hell” – opened up in the desert of north Turkmenistan, and has been burning ever since. Now, Canadian explorer George Kourounis has became the first to make the descent into the fiery pit to look for signs of life (x)
"We did find some bacteria living at the bottom that are very comfortable living in those high temperatures, and the most important thing was that they were not found in any of the surrounding soil outside of the crater," he says. "Outside of our solar system, there are planets that do resemble the conditions inside this pit, and [knowing that] can help us expand the number of places where we can confidently start looking for life outside of our solar system."

THIS IS AMAZING SPREAD THE WORD
NPR Science: Sorry, Lucy: The Myth Of The Misused Brain Is 100 Percent False
- ERIC WESTERVELT, HOST:
- If you went to the movie theater this weekend, you might've caught the latest Scarlett Johansson action movie called "Lucy." It's about a woman who develops superpowers by harnessing the full potential of her brain.
- (SOUNDBITE OF FILM, "LUCY")
- SCARLETT JOHANSSON: I'm able to do things I've never done before. I feel everything and I can control the elements around me.
- UNIDENTIFIED MAN: That's amazing.
- WESTERVELT: You've probably heard this idea before. Most people only use 10% of their brains. The other 90% of the basically dormant. Well, in the movie "Lucy," Morgan Freeman gives us this what-if scenario?
- (SOUNDBITE OF FILM, "LUCY")
- MORGAN FREEMAN: What if there was a way of accessing 100% of our brain? What might we be capable of?
- DAVID EAGLEMAN: We would be capable of exactly what we're doing now, which is to say, we do use a hundred percent of our brain.
- WESTERVELT: That is David Eagleman.
- EAGLEMAN: I'm a neuroscientist at Baylor College of Medicine.
- WESTERVELT: And he says, basically, all of us are like Lucy. We use all of our brains, all of time.
- EAGLEMAN: Even when you're just sitting around doing nothing your brain is screaming with activity all the time, around the clock; even when you're asleep it's screaming with activity.
- WESTERVELT: In other words, this is a total myth. Very wrong, but still very popular. Take this clip from an Ellen DeGeneres stand-up special.
- (SOUNDBITE OF STAND-UP SPECIAL)
- ELLEN DEGENERES: It's true, they say we use ten percent of our brain. Ten percent of our brain. And I think, imagine what we could accomplish if we used the other 60 percent? Do you know what I'm saying?
- AUDIENCE: (LAUGHTER).
- (SOUNDBITE OF FILM, "TOMMY BOY")
- DAVID SPADE: Let's say the average person uses ten percent of their brain.
- WESTERVELT: It's even in the movie "Tommy Boy."
- (SOUNDBITE OF FILM, "TOMMY BOY")
- SPADE: How much do you use? One and a half percent. The rest is clogged with malted hops and bong residue.
- WESTERVELT: Ariana Anderson is a researcher at UCLA. She looks at brain scans all day long. And she says, if someone were actually using just ten percent of their brain capacity...
- ARIANA ANDERSON: Well, they would probably be declared brain-dead.
- WESTERVELT: Sorry, "Tommy Boy." No one knows exactly where this myth came from but it's been around since at least the early 1900's. So why is this wrong idea still so popular?
- ANDERSON: Probably gives us some sort of hope that if we are doing things we shouldn't do, such as watching too much TV, alcohol abuse, well, it might be damaging our brain but it's probably damaging the 90 percent that we don't use. And that's not true. Whenever you're doing something that damages your brain, it's damaging something that's being used, and it's going to leave some sort of deficit behind.
- EAGLEMAN: For a long time I've wondered, why is this such a sticky myth?
- WESTERVELT: Again, David Eagleman.
- EAGLEMAN: And I think it's because it gives us a sense that there's something there to be unlocked, that we could be so much better than we could. And really, this has the same appeal as any fairytale or superhero story. I mean, it's the neural equivalent to Peter Parker becoming Spiderman.
- WESTERVELT: In other words, it's an idea that belongs in Hollywood.
