two thing I didn’t know (and probably you too) about the giant isopod (Bathynomus sp) swims very well, and digs burrow.
A important detail is the two red dots are from lasers mounted on the ROV and are 10 cm apart (this techique is called photogrammetry)

It’s a snap… To produce electricity from polonium-210 in a tiny atomic generator. The model shown here is still going strong after a full year of operation. And it has survived impact, vibration, and acceleration tests (requirements for space exploration) without damage, says its designer, The Martin Co. SNAP—system of nuclear auxiliary power—converts heat of radioactive decay into electricity by a series of thermocouples.

I am just sitting on my bed shrieking in delight ARE YOU GUYS SEEING THIS
I want this in my life.
EXCUSE ME I KNOW THIS IS NOT RECIPES BUT DO YOU UNDERSTAND HOW MINDBLOWINGLY AMAZING THIS IS????!?!?
FUCKING TAKE MY MONEY YOU BRILLIANT INDIVIDUALS!
That same slime mold once affirmed that the Tokyo subway is pretty well-designed.
Slime mold was grown on an agar gel plate shaped like America and food sources were placed where America’s large cities are.
The result? A possible look at how to best build public transportation.
I just really like the idea of slime mold on a map of the US. It’s beautiful.
Natural computation: it’s a thing, and it’s awesome. What is the universe but a really, really complicated computer?
Today, if you searched all of North America north of Mexico, you would find only 17 species of land mammals that could be called megafauna, a term for animals that exceed 100 pounds. If you exclude the rare predators and arctic animals, you are left with just 10 species: pronghorn, mountain goat, bighorn sheep, bison, elk, moose, mule deer, white-tailed deer, black bear, and grizzly bear.
If not for the end-Pleistocene extinctions just 13,000 years ago, there would still be another 40 species of North American megafauna. They would include five species of deer or moose, two llamas, a camel, three horses, four ground-sloths ranging from 400 pounds to 3 tons, a 600-pound armadillo, a 2,000-pound turtle-like glyptodont, two ox-like species, a 5-ton mastodon, a 6-ton woolly mammoth, and a 9-ton Columbian mammoth. Did I mention the 400-pound beaver? Before you jump into your time machine for a true North American safari, be advised that there were also scimitar-cats, American lions, and sabertooths, each as big as or bigger than an African lion. There were three huge bears, including the 1,800-pound giant short-faced bear, the largest mammalian predator that ever walked the Earth."
How the fuck does Bill Nye expect this to happen? What do you want to do, force women to enroll in science courses, regardless of whether or not they want to do it? Just for the sake of having “enough” women? Why the fuck do these fractions matter so much? It’s not like people are holding guns to our head and threatening to kill us if we become interested in science.
Maybe, just maybe, a lot of us DON’T FUCKING WANT to be scientists. Is that a crime?
Hi there, princess-munchkin. Female engineering student here.
Bill Nye is not saying that you HAVE to be a scientist, and you are right that no one is holding a gun to my head because I am interested in science, but let me tell you some of the struggles of being a woman in the STEM fields.
1) Because I am a woman, I am not expected these fields. I first fully realized this when I was in high school, on my robotics team. See, although my robotics team was about 50% female, most of the women were part of the “business administration” side of things: finance, marketting, PR, membership, etc. Was this a problem? Absolutely not. But I was there to be an engineer, and specifically, to be the robot programmer. This was met with a lot of hesitation at first from some of the other students (all of whom happened to be male. This is not necessarily a bad thing.) You see, all of the robot programmers before me were guys. Computer programming is just a thing that guys do, or so they thought. Even after I had proved myself to the mentors on the team, many of the students still underestimated my abilities. There were rumors going around that I wouldn’t have been able to program the robot at all if the lead software mentor wasn’t there to help me. This was just flat-out false, but it wasn’t until I won an award for the team that the other students actually saw my merit.
2) There is not a lot of encouragement for women to go into these fields. I first noticed this when I was in elementary school. I was always interested in math, science, you name it, but many of my teachers and family members pushed that to the side for a long time. When I asked for legos for christmas, I would get ballet slippers. In fact, for a long time, I was training to be a professional dancer. I loved to dance. I loved math more, but no one seemed to notice that about me. It wasn’t until I had a long conversation with one particular teacher in high school that I decided to look into engineering. I had never even considered it as an option before, because no one decided to encourage me to pursue my interest in science. If it hadn’t been for that teacher, I would probably not be at the school I am at right now.
3) For a long time, Engineering/Science/Math WAS a “boys only” club. Let me tell you when some of the top technical schools and societies started letting women in:
- RPI, The oldest tech school in the country, founded in 1824. Started admitting women in 1942 to “replace men called to war.” Campus housing for women wasn’t constructed until 1966.
- Tau Beta Pi, the Engineering Honors Society - Founded in 1885. Started admitting women in 1968.
- Caltech - Currently rated #3 in undergraduate engineering. Founded in 1891. Started admitting women in 1970.
- Georgia Tech - Currently rated #5 in undergraduate engineering. Founded in 1885. Started admitting women in 1952.
Do you see the implications of this? Engineering has been a part of our society since around the late 1800s (in the case of RPI, since the 1820s), but women weren’t even allowed in for the most part until the 1950s, regardless of their merit.
4) Because of the fact that it was a “boys only” club for such a long time, there are not a lot of women engineers and scientists to look up to. When you’re reading your physics, chemistry, and math text books, the majority of those theories were came up with by men. It is true that much of our history was written by White Men, but this does not mean that the fact that there are few women scientists to look up does not matter.
So, as you can hopefully see, princess-munckin, or anyone else that shares the opinions of princess-munchkin, Bill Nye was not arguing that women that are not interested in STEM should go into those fields anyway. But he IS arguing against all of the systematic barriers set up against women who ARE interested in engineering and science. There are several women out there who are just as good as the boys at math and science, but will never pursue their interests because it just doesn’t seem like an option. That was me for a long time. I am super grateful for the fact that I fought against that, and that I ended up where I am.
if you don’t like science, fine. Don’t be a scientist. But if one day you have a daughter and she shows interest in being a scientist, PLEASE encourage her. Because Bill Nye is right, there needs to be more women scientists in the world.
Chernobyl’s Wildlife Survivors
When Mary Mycio tells people she visited the radioactive fallout zone around Chernobyl to study the region’s animals, the questions are always the same. Do the animals have two heads? Do they glow?
Actually, according to Mycio and photographer and field biologist Sergey Gaschak, the animals are thriving. The 1986 explosion, the worst nuclear accident in history, forced 300,000 people to abandon the highly contaminated area around the wreckage of the power plant. Communal farms turned to wetlands and forests, and the animals came back. The area is now the largest, if unintentional, wildlife sanctuary in Europe.
Gaschak has been photographing animals near Chernobyl since 1995. He uses camera traps with motion detectors to capture some of the animals, but he sees and photographs plenty of them in person: lynx, otters, eagle owls, Przewalski’s horses, several species of bats, and footprints of brown bears.

all right guys here it is THE BIG GAY ANIMAL SEX POST
or in other words, “Why Nonhuman Homosexual and Asexual Behavior has both Survival and Reproductive Benefits” aka that lit review i’d like to write if i could ever be arsed to get around to it
yes reproductive benefits you heard correctly we’re gonna get there but first we better do a basic rundown of what I mean by homosexual/asexual behaviors

Arc-length parametrization of an Archimedean spiral: Part 2
Some anonymous person asked me to do this with a linear movement from the starting position to the ending position of each point, instead of along the spiral’s curve, as I did before.
Since it would require an incredibly tiny change to the code, I decided to give it a shot.
On the left, the colors are based on the angle in the original parametrization. On right, the colors are based on the number of turns. While the transformation is continuous, it is not smooth: this transition creates “kinks” in the curve partway through.
