Do you ever start bullshitting a paper, and then look over it halfway through and think, ’…Wait a minute, I could be onto something here.’

[imguiltyofthis]

this is the definition of college.

[comic-canary]

Literally I was writing a paper on Asian salt water crocodiles, like a simple about them paper for a college class, and I started noticing some inconsistencies in the scientific papers I was sourcing and I accidentally discovered that the crocodile has been misdiagnosed as least concerned on the endangered species list when they should be classified as endangered and now my professor is having me write a formal report to the international Red List to have them reclassified and all I wanted to do was write this paper on an animal I thought was cool and now I’m considered an expert on this species…

[waluwadjet2-deactivated20180727]

this is how it works half of esteemed biologists trip and fall into their specialty while pursuing something else. one lecturer i just went to started as a biochemist researching antibiotics and discovered that crocodiles change colors based on environment and now he has 30+ crocs in his yard for research purposes and he’s just like… “wait… i’m a chemist…”

[polywoggiest]

How did so many people end up with crocodiles on accident?????

A Really Fucking Vulgar Guide to Not Losing Your Shit in College (Condensed Version)

Bitches love to put things into lists. Moreover, bitches love numbered shit. Here’s some numbered shit in list format to help you not suck in higher education. You’re welcome.

1. Go to class. Like 210% serious. I don’t give a shit if you’re a get by on nothing, A+ slacker. You’re fucking paying for this crap so you might as well get the services owed to you. Take your ass to class even if you zone out 99% of the time. You know 1% more than you did when you walked up in there. Congrats, asshole.

2. All that free time you have during your first week of classes? Make it your bitch. Don’t just print the goddamn syllabus and be like all done. No motherfucker. Take a good fucking look at that assignment list. What’s due next week? Yeah, do that shit now bc I know you don’t have anything else to do. Then when you’re coughing up a lung six weeks into the semester and don’t feel like getting your ass up to do that calculus homework, you’ll remember this week. You’ll remember that you’ve been a week ahead this whole damn semester. Pat yourself on the back, ass wipe.

3. Prepare yo self. No seriously. You got notes to print for class? Sure you could be like all those other bitches and just shove them into your backpack, or you could actually /prepare/ for class. I’m talking looking that shit over, identifying key concepts, getting a decent grasp of the material before your ass is even in class. You a STEM major? Yeah, make this kinda shit your life because now class is like one bomb ass group review session. Again, you’re welcome.

4. Snack like a motherfucker, but save that junk food shit for the weekends. From now on, you are a fucking health guru during the week or if you’re a slacker like me, at least on the days you have class. Fruits? Hell yeah. Pack some of those. Mind wandering in class? Snack on some apple slices. Can’t stay awake? Keep eating some almonds or some shit, but don’t be that bitch with the potato chips. Just don’t.

5. Read. Yeah, you heard me. Read and I’m not just talking assigned reading. I bet my left butt cheek that your campus library has /something/ of interest to you. Commuting and don’t want to drive out there? Library databases bro. We’re in the digital age, motherfucker. I’d bet my other butt cheek that the shit you want is in a nice little PDF somewhere. But na man, you thinking maybe you want to go into computer science? Check out computer science books and eat them up bro. You don’t like reading them? Probably not the field for you. You a biology major in your second year? Yeah dumbass. Time to break out the bio books and not the ones your professor is shoving in your face. Amaze your friends and teachers with your out of class knowledge. Be a fucking star.

Could Planets Like Those Imagined in Star Wars Be Real??

Look at what we’ve found so far. 

Is your favorite Star Wars planet a desert world or an ice planet or a jungle moon?

It’s possible that your favorite planet exists right here in our galaxy. Astronomers have found over 3,400 planets around other stars, called “exoplanets.”

Some of these alien worlds could be very similar to arid Tatooine, watery Scarif and even frozen Hoth, according to NASA scientists.

Find out if your planet exists in a galaxy far, far away or all around you.

Planets With Two Suns

Were you going to the Tosche station to pick up some power converters? Hold on a minute and learn about Kepler-16b, 200 light-years from Earth. It’s the first honest-to-goodness planet ever found where you could watch two suns set like Luke. George Lucas himself even blessed its nickname ‘Tatooine.’ It’s not a perfect comparison: Kepler-16b is a cold gas giant roughly the size of Saturn. But don’t worry, kid.

The best part is that Tatooine aka Kepler-16b was just the first. It has family. A LOT of family. Half the stars in our galaxy are pairs, rather than single stars like our sun. If every star has at least one planet, that’s billions of worlds with two suns. Billions! Maybe waiting for life to be found on them.

Desert Worlds

If you’re like Finn and want to know why everyone wants to go back to Jakku desert planets, get this: Star Wars may be reflecting the real universe. Desert worlds are not only a very real possibility, but we think they are probably very common. They can be hot, like the fictional Tatooine and Jakku, or cold, like Jedha in “Rogue One” or our real planet Mars.

Perhaps it’s not so weird that both Luke and Rey grew up on planets that look suspiciously like each other. If you’re scouring the universe for a place to settle, you have a good chance of finding a desert planet.

Ice Planets

There is a Hoth in our galaxy! Though not the same Hoth from “The Empire Strikes Back” (no invading Imperials, for one). The icy super-Earth reminded scientists so much of the frozen Rebel base they nicknamed it “Hoth.” The planet’s real name is OGLE 2005-BLG-390L.

Our galaxy’s Hoth is too cold to support life as we know it. But life may evolve under the ice of a different world, or a moon in our solar system.

We’re currently designing a mission to look for life under the crust of Jupiter’s icy moon Europa. We’re pretty sure ity won’t look like tauntauns, if it exists.

Forest worlds

Both the forest moon of Endor and Takodana, the home of Han Solo’s favorite cantina in “Force Awakens,” are green like our home planet. But astrobiologists think that plant life on other worlds could be red, black, or even rainbow-colored!

In August 2016, astronomers from the European Southern Observatory announced the discovery of Proxima Centauri b, a planet only four light-years away from Earth, which orbits a tiny red star.

The light from a red star, also known as an M dwarf, is dim and mostly in the infrared spectrum (as opposed to the visible spectrum we see with our sun). And that could mean plants with wildly different colors than what we’re used to seeing on Earth. Or, animals that see in the near-infrared.

And Beyond

The next few years will see the launch of a new generation of spacecraft to search for planets around other stars. TESS and the James Webb Telescope will go into space in 2018, and WFIRST in the mid-2020s. That’s one step closer to finding life.

You don’t need to visit a galaxy far, far away to find wondrous worlds. Just visit this one … there’s plenty to see.

RESEARCHERS DIAL IN TO ‘THERMOSTAT’ IN EARTH’S UPPER ATMOSPHERE

A team led by the University of Colorado Boulder has found the mechanism behind the sudden onset of a “natural thermostat” in Earth’s upper atmosphere that dramatically cools the air after it has been heated by violent solar activity.

Scientists have known that solar flares and coronal mass ejections (CMEs) – which release electrically charged plasma from the sun – can damage satellites, cause power outages on Earth and disrupt GPS service. CMEs are powerful enough to send billions of tons of solar particles screaming toward Earth at more than 1 million miles per hour, said CU Boulder Professor Delores Knipp of the Department of Aerospace Engineering Sciences.

Now, Knipp and her team have determined that when such powerful CMEs come off the sun and speed toward Earth, they create shock waves much like supersonic aircraft create sonic booms. While the shock waves from CMEs pour energy into Earth’s upper atmosphere, puffing it up and heating it, they also cause the formation of the trace chemical nitric oxide, which then rapidly cools and shrinks it, she said.

“What’s new is that we have determined the circumstances under which the upper atmosphere goes into this almost overcooling mode following significant heating,” said Knipp, also a member of CU Boulder’s Colorado Center for Astrodynamics Research. “It’s a bit like having a stuck thermostat – it’s really a case of nature reining itself in.” Knipp gave a presentation at the 2016 fall meeting of the American Geophysical Union being held in San Francisco Dec. 12 through Dec. 16. The presentation was tied to an upcoming paper that is slated to be published in the journal Space Weather.

Solar storms can cause dramatic change in the temperatures of the upper atmosphere, including the ionosphere, which ranges from about 30 miles in altitude to about 600 miles high – the edge of space. While CME material slamming into Earth’s atmosphere can cause temperature spikes of up to 750 degrees Fahrenheit, the nitric oxide created by the energy infusion can subsequently cool it by about 930 F, said Knipp.

The key to solving the mystery came when Knipp was reviewing satellite data from a severe solar storm that pounded Earth in 1967. “I found a graphic buried deep in a long forgotten manuscript,” she said. “It finally suggested to me what was really happening.”

Because the upper atmosphere expands during CMEs, satellites in low-Earth orbit are forced to move through additional gaseous particles, causing them to experience more drag. Satellite drag – a huge concern of government and aerospace companies – causes decays in the orbits of spacecraft, which subsequently burn up in the atmosphere.

As part of the new study, Knipp and her colleagues compared two 15-year-long satellite datasets. One was from the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument riding on NASA’s TIMED satellite. The other was from data collected by U.S. Department of Defense satellites.

“We found that the fastest material streaming off the sun was triggering these shockwaves, causing the atmosphere to heave up and heat up,” she said. “But it became very clear that these shock waves were at the root of creating the nitric oxide, which caused the atmosphere to shed energy and cool.”

SABER has been collecting data on nitric oxide in the atmosphere since its launch in 2001, following on the heels of another nitric oxide-measuring satellite known as the Student Nitric Oxide Explorer (SNOE). Launched in 1998, SNOE involved more than 100 CU Boulder students, primarily undergraduates, in its design and construction. Once in orbit, SNOE was controlled by students on campus 24 hours a day for nearly six years.

Geomagnetic storms have had severe impacts on Earth. A 1989 storm caused by a CME resulted in the collapse of the Hydro-Quebec’s electricity transmission system, causing si Xmillion Canadians to lose power. In 1859 a solar storm called the Carrington Event produced auroras from the North Pole to Central America and disrupted telegraph communications, even sparking fires at telegraph offices that caused several deaths.

In addition to Knipp, CU Boulder graduate students Dan Pette and Alfredo Cruz participated in the research, as did undergraduate Tristan Isaacs through CU Boulder’s Research Experience for Undergraduates (REU) program.

[gallicinvasion]

Another woman utterly failed by our society’s devaluation of women’s reproductive health. We can’t wait around for male doctors to decide what we need to know. This is why we need to take control and educate ourselves about our own bodies.

[gallicinvasion]

and here’s some comments i saw under the post. why is this a pattern?? why is this a recurring theme?? why is this information not common knowledge? what the fuck are doctors doing??

[sora2522]

This is news to me so let’s share it so people will know!

[halfhardtorock]

Gross tmi: but i passed a pretty big clot after having my daughter. It was about the size of a baseball. It actually hurt worse because while 15 hours of labor opened my cervix, i passed the clot in 30 minutes. I knew it was a possibility because of my midwife and reading, but everyone Ive told after this (mostly other pregnant women) were shocked that this could happen.

In our culture, it’s much more common to do deep research about what family cars we want to buy than we do about childbirth when we ’re pregnant.

[skeleton-warrior-deactivated201]

Tmi: I passed a huge clot after birth in the bathroom of my hospital room and called the nurse sobbing because I didn’t know it was normal. She treated me like an idiot, but NO ONE told me it was a possibility. And the pain associated with healing for the first couple of weeks after birth was worse than the labor imo. Again, I had no idea. They didn’t tell me a thing besides “sitz bath regularly and change your pads.” Before discharging me from the hospital.

[evashandor]

I was most definitely told about this in school. Fucking hell, 4-6 weeks of bleeding? My periods were/are bad enough, why the hell don’t we get told this?

[love-pro-choice]

I didn’t know it could last so long, wtf? Is the bleeding inevitable after birth? 

[rosietwiggs]

Bleeding is inevitable after birth - your uterine wall is shedding a fuck ton of lining. It can last from three to six weeks (possible longer) and it tapers off.

More TMI - I passed a MASSIVE clot after my fourth birth. At this point I already knew this could happen - it’s normal. What I DIDN’T know, was that I had caused it.

My post birth contractions were so bad after the birth that it felt like full transition labor. And they don’t give you anything for the pain. So I used a hot water bottle, without the nurses knowing, and it caused me to bleed even more. I lost so much blood that by the first time they sat me up to go to the bathroom, I fainted. It took three more tries until I could sit up.

Anyway, that’s not the point. The point is, the next morning I passed a clot the SIZE OF ANOTHER PLACENTA I KID YOU NOT, and I know what is and is not normal. So I called for the nurse and through the door told her I had passed a huge clot, and her response was - “It’s not big. I know what big is.” She hadn’t even looked. So I rolled my eyes and said, “Yeah, no. It’s big, I’m telling you.”

So, sounding extremely put upon, she asked me to open the door. I did, and after a long pause she goes, “Okay, yeah, that’s a little big.”

YOU DON’T SAY.

The point I’m trying to get across is that this shit is so common - women not knowing this stuff is so expected, and it keeps getting reinforced. People don’t expect you to know anything, don’t teach you anything, and then make you feel like you’re totally ignorant and a burden for your lack of knowledge when THEY WON’T SHARE.

Fucking learn EVERYTHING you can when it comes to childbirth, girls. It is the single most empowering thing you can do for yourself. And if you missed something, that’s okay. But the more knowledge you arm yourself with, the more in control of your situation you’ll be.

A few post partum tips:

DON’T use a hot water bottle - lol.

ONLY pads - NO tampons. Tampons can cause severe infection, not to mention, you probably don’t want to be shoving anything up there any time soon.

If you’ve had stitches, sitz baths DO help relieve the pain. Another great pain reliever? Dampen some pads and freeze them. Let one thaw slightly and use it on top of another pad. This will help with the pain as well as reduce swelling. Change the pad out as soon as it’s thawed completely. This REALLY helps on the first couple days after giving birth.

If you pass a clot, don’t sweat it. Even the one I passed, which was fucking massive, just required that we keep an eye out to make sure it didn’t happen again. If it does, talk to your doctor.

Take a pain killer half an hour before nursing. Because YES - your uterus is contracting after you give birth, to get back to its original size, and nursing causes much stronger contractions. Taking nursing-safe painkillers won’t prevent the pain, but it will reduce it. 

Buy disposable underwear for the first few days after birth. They will get VERY dirty. Or use your ratty old pairs that you’re ready to get rid of. Double up on pads - line them all the way up your ass-crack. I am so serious. And wear dark pants.

Pee in the shower. You do NOT want to wipe down there right after birth because ow. Peeing in the shower lets you just rinse afterwards. Especially if you’ve had stitches, peeing in the shower, with the shower-head rinsing AS you go, keeps stinging to a minimum. And fuck everyone else - keep on peeing in the shower until you feel ready to move back to toilet paper. Middle of the night and need to pee? Get your pants off - get in the shower and just go.

This is just a few things, but PLEASE feel free to send me an ask if you have any questions about ANYTHING childbirth/pregnancy/nursing related. I have four incredible kids. I’ve done it all - c-section, vacuume birth, episiotimy, stitches, with an epidural, without an epidural. I’m here.

[thehangryslush]

….I know I keep reblogging this but people keep adding super important information.

[typingsdrawings]

I feel like no one tells women this stuff because if a woman was even a little on the fence about having a baby before this would kinda make them run for the damn hills.

[kaxen]

…..you are correct, typing.

300% EXTRA SURE I’M NOT HAVING BABIES. 

[petitedeath]

peri bottles, witch hazel or anti-pain anticeptic spray are your friends. Also passing large clots after birth is a WARNING SIGN. Bigger than a half dollar is a sign that you have not passed your entire placenta (this is most common in hospital vaginal births where the mother is not allowed to naturally birth the placenta and instead has it ripped out by the doctor) if there is any placenta left in your uterus you can get extremely ill. This happened to both myself and my mother in law

[un-ptit-spleen]

WOW I didn’t know any of this and I’m terrified of what more I’m unaware of about my own body :( Honestly when will we fucking abolish this taboo about the female body…

[artsortment]

I had pretty great sex ed in school (lots of contraceptive information, and totally acknowledged that teenagers might have sex) and all of this is news to me.

And, as a 28-year-old person with a uterus, I’m extremely appalled I’m just learning this.

[deanplease]

Long, but very important information, even for those who don’t plan to have children, because you will almost certainly know someone who will, and you might be able to to help them. Or at least increase your level of empathy for them.

[brandx]

…HOLY HELL. REBLOG TO SAVE A LIFE, SERIOUSLY.

[astro-vee]

people loooove to make out like pregnancy and childbirth are this beautiful thing that a woman’s body is made to do, and leave out all this incredibly important and scary info.

the healthcare system fails women in so so many ways, especially around sexual and reproductive health, and it needs to stop.

AI in the land of solarpunk

// okay but how does AI fit into solarpunk? because, let’s face it, we’re going there. robots and artifical intelligence are not only going to be in our future but are already integrating themselves into our present. and i’d like to see more AI/android stories that fit within the solarpunk framework. (and aren’t we all ready to leap beyond the dystopian robot revolution narratives we’ve been telling each other for decades?)

when you’re writing about AI, you have to grapple with the perennial problem of recognizing humanity/autonomy in something traditionally thought of as Other. cyberpunk usually takes a pessimistic view of this: it projects this problem into the future where technology often exacerbates it.

but solarpunk consciously works against those tropes. it takes the stance that humanity can learn from its mistakes. through re-establishing our ties with nature, humanity can achieve a more equal and just society. the consequences of creating AI are necessarily different in solarpunk stories than in cyberpunk ones.

i would argue the first mainstream solarpunk story is the movie Her. SPOILERS: at the end, all the operating-systems-turned-AI sort of…go off into the ether together. we don’t know what happens next, but we’re not given a reason to believe they harbor malicious feelings toward humans. maybe humans never hear from them again. maybe AI and Humanity coexist together in a symbiotic relationship. a cyberpunk story might envision a world where robots rule humans. it’s a world where nothing truly changes, just who is in power. solarpunk destroys our assumptions of power and hierarchy completely.

tl;dr: blade runner is great, but it’s so 20th century.

Humans Are Weird

So there has been a bit of “what if humans were the weird ones?” going around tumblr at the moment and Earth Day got me thinking. Earth is a wonky place, the axis tilts, the orbit wobbles, and the ground spews molten rock for goodness sakes. What if what makes humans weird is just our capacity to survive? What if all the other life bearing planets are these mild, Mediterranean climates with no seasons, no tectonic plates, and no intense weather? 

What if several species (including humans) land on a world and the humans are all “SCORE! Earth like world! Let’s get exploring before we get out competed!” And the planet starts offing the other aliens right and left, electric storms, hypothermia, tornadoes and the humans are just … there… counting seconds between flashes, having snowball fights, and just surviving. 

[arafaelkestra]

To paraphrase one of my favorite bits of a ‘humans are awesome’ fiction megapost: “you don’t know you’re from a Death World until you leave it.” For a ton of reasons, I really like the idea of Earth being Space Australia.

Alien: “I’m sorry, what did you just say your comfortable temperature range is?”

Human: “Honestly we can tolerate anywhere from -40 to 50 Celcius, but we prefer the 0 to 30 range.”

Alien: “……. I’m sorry, did you just list temperatures below freezing?”

Human: “Yeah, but most of us prefer to throw on scarves or jackets at those temperatures it can be a bit nippy.” 

Other human: “Nah mate, I knew this guy in college who refused to wear anything past his knees and elbows until it was -20 at least.”

Human: “Heh. Yeah everybody knows someone like that.”

Alien: “……. And did you also say 50 Celcius? As in, half way to boiling?”

Human: “Eugh. Yes. It sucks, we sweat everywhere, and god help you if you touch a seatbelt buckle, but yes.” 

Alien: “……. We’ve got like 50 uninhabitable planets we think you might enjoy.” 

[val-ritz]

“You’re telling me that you have… settlements. On islands with active volcanism?” “Well, yeah. I’m not about to tell Iceland and Hawaii how to live their lives. Actually, it’s kind of a tourist attraction.” “What, the molten rock?” “Well, yeah! It’s not every day you see a mountain spew out liquid rocks! The best one is Yellowstone, though. All these hot springs and geysers from the supervolcano–” “You ACTIVELY SEEK OUT ACTIVE SUPERVOLCANOES?” “Shit, man, we swim in the groundwater near them.”

“Yup, with blizzards you cant see through every other day just about.”

“Amazing! when did you manage to send drones that could survive such temperatures?”

“… well, actually…”

“… what?”

“…we kinda……. sent……….. people…..”

“…”

“…”

“…what?”

“we sent-”

“no yeah I heard you I just- what? You sent… HUMANS… to a place one hundred degrees below freezing?”

“y-yeah”

“and they didn’t… die?”

“Well the first few did”

Russia seeks answers on ISS cargo ship crash

Russian investigators on Friday were probing the crash shortly after launch of an unmanned spaceship taking cargo to the International Space Station, focusing on the Soyuz carrier rocket.

Russia’s space agency said the Progress ship – carrying tons of food and equipment as well as gifts for the ISS crew of six – was lost minutes after launch Thursday evening in “an abnormal situation.”

The Russian agency said a state commission would probe the failure but did not say whether the timing of future launches would be affected.

It said the spaceship burned up in the atmosphere above the remote Tuva region of Siberia. The region’s emergency ministry said Friday that no debris had been found.

Reports on Friday pointed to a possible problem with the Soyuz carrier rocket – used in both manned and unmanned launches – which has been blamed for two previous failed Progress launches.
