This isn't an alien world — it's a representation of the winds traveling from East to West (in blue) and West to East (in red) here on Earth. And this is just one of the fantastic images that won the 2013 Science As Art contest at Princeton University. See a few more below.

Top image: East-West, West-East by Martin Jucker, Jury First Place

Every year, Princeton chooses the best science art images of the year — here are some of the previous year's best images. This year's include the above image in "atmospheric and oceanic studies," plus a ton of others, some of which are below.

People's First Place: Messenger Meshwork Shawn C. Little (postdoc), Kristina S. Sinsimer (postdoc), Elizabeth R. Gavis (faculty), and Eric F. Wieschaus (faculty) Department of Molecular Biology

The fruit fly ovary consists of about 100 egg chambers. Each chamber contains 15 "nurse cells." These surround the oocyte, or egg cell, which ultimately will develop into a baby fruit fly. The nurse cells synthesize RNA molecules that are ultimately deposited into the oocyte. Here we see four nurse cells. Each red or green dot is an individual RNA molecule, which is produced from DNA (shown in blue). The RNA molecules intermingle on a threadlike network that allows them to move from one nurse cell to another and then into the developing egg (which we don't see in this image).

People's Second Place: Bridging the Gap Jason Wexler (graduate student) and Howard A. Stone (faculty) Department of Mechanical and Aerospace Engineering

When drops of liquid are trapped in a thin gap between two solids, a strong negative pressure develops inside the drops. If the solids are flexible, this pressure deforms the solids to close the gap. In our experiment the solids are transparent, which allows us to image the drops from above. Alternating dark and light lines represent lines of constant gap height, much like the lines on a topological map. Â These lines are caused by light interference, which is the phenomenon responsible for the beautiful rainbow pattern in an oil slick. The blue areas denote the extent of the drops. Since the drops pull the gap closed, the areas of minimum gap height (i.e. maximum deformation) are inside the drops, at the center of the concentric rings.

Light eddies Mitchell A. Nahmias (graduate student) and Paul R. Prucnal (faculty) Department of Electrical Engineering

Fiber optic networks have transformed global communications by moving digital bits of information around the planet at the speed of light. By combining lasers with artificial neural networks, it may one day be possible to create high-speed processors that react to incoming data far faster than current computers could ever handle. Our brains are composed of billions of individual cells called neurons, which communicate along millions of billions of channels with electrochemical signals. This computer model visualizes a laser that behaves like a neuron by plotting a so-called "phase space." Notice that the lines swirl inwards like a whirlpool to converge at stable equilibrium points, indicating that the laser will stabilize over time. Studying these trajectories helps us understand how our devices emit and receive pulses of light that mimic the way in which neurons communicate.

The Universe exploded into being 14 billion years ago and remnant light from this explosion is still visible today. Our group measures this light at a site 17,000 feet high in the Atacama Desert in Chile. We use special "detectors" developed in a collaboration between Princeton and other institutions. These detectors use antennas to capture the non-visible wavelengths of light focused by our 6 meter telescope. This photograph looks down into feedhorns, small corrugated structures that allow particles of light to funnel toward the antennas. The antennas are tiny dark triangles suspended upon a thin membrane on a silicon detector wafer that attaches to the base of each feedhorn. The membrane is thin enough that you can see the gold-plated reflective wafer behind the antennas. Light from the camera is reflecting off the gold-plated wafer, casting a golden gleam.

"We are linked by blood," writes Joyce Carol Oates, "and blood is memory without language." The network of blood vessels known as the vascular system connects all tissues and organs. Confocal imaging gives us the opportunity to view the vascular system by illuminating the whole body with fluorescent light and providing a translucent image of the subject. This mosaic of different confocal images gives us an entire picture of a mouse embryo. Here the vascular system, rather than appearing in a familiar blood-red, is represent by the color green. The blue color represents the DNA that will direct the embryo's growth.

That sweet little face peering out of a coral labyrinth is that of a a goby fish. A goby fish is dependent on coral for its home, and in turn will often clean algae that would otherwise smother the coral. I took this photo in the course of field research for the Coral Reefs lab course in Panama (EEB 346) for a project on the ecology of coral reefs, focusing on interactions between corals, algae, and sea urchins.

Caenorhabditis elegans (C. elegans) worms are stored on agar plates covered with a lawn of E. coli bacteria as their food source. Sometimes when the C. elegans have consumed all of the bacteria, they begin to clump together as seen in this image. I found the pattern on this plate particularly lovely, and was able to capture it with my cell phone by holding the lens of my phone's camera up to the microscope eyepiece. I've since shared the photo on social networking sites and have had friends who've never been interested in biology ask me more about my work because of this photo. To me, this image represents the simple pleasure of finding something beautiful when you don't expect to, and it shows how easy it is to connect science with new audiences by simply clicking 'share.'

The history of science fiction television is full of shows that have a lot of wonderful stuff... but you just know they could be even more awesome if someone seized their raw potential with both hands. Which classic TV show do you wish you could personally make a new version of?

As always, please include a picture — along with your explanation of just how you'd reimagine your chosen show. Thanks!

Why does Khan transport himself to the deserted part of Kronos? He's got a magic transwarp device that can send him to any planet, anywhere — why go to the Klingon homeworld? It would make sense if he's still working for Admiral Marcus, since Admiral Marcus wants an excuse to start a war with the Klingons. But this is after Khan has already turned against Marcus — once he's in the Enterprise brig, he tells Kirk that he decided to strike at Starfleet after Marcus betrayed him. So by going to Kronos, he's playing into Marcus' hands.

(Edited to add: Khan gets incredibly lucky — if Kirk had followed Marcus' orders and launched those torpedoes, Khan would be dead along with all his people, and Marcus would have exactly what he wants.)

Back in the mid-1970s, legendary filmmaker Alejandro Jodorowsky tried to make a movie of Frank Herbert's Dune, featuring people like Mick Jagger, Orson Welles and Salvador Dali, with designs by H.R. Giger and Chris Foss. It would have been astonishing, whether or not it lived up to the book. Now, a new documentary tells the story of that failed enterprise.

The documentary Alejandro Jodorowsky's Dune just premiered at Cannes, and apparently it's spell-binding.

Salon raves:

I don’t hope to see a movie at this festival, or all year long, that’s as inspiring as Frank Pavich’s documentary “Jodorowsky’s Dune,” the story of an enormously influential film that was never made. That may sound strange on a number of levels: How does one of the most famous collapsed productions in cinema history, a failure so dire that it derailed its director’s career for many years, become a source of inspiration? Especially when the resulting documentary largely consists of a man in his 80s sitting around and talking? Well, when the old guy talking is as brilliant, passionate, ferocious and hilarious as Jodorowsky, and when the stories he tells convince you that his quixotic dream of making an enormous science-fiction spectacle that combined star power, cutting-edge technology, philosophical depth and spiritual prophecy nearly came true, it’s as if you glimpse his vision of a transformed world where everything is possible.

And Variety adds:

Pavich does an admirable job tracking down surviving parties (except for the suspicious-sounding cast), opting for a humorous rather than indignant tone to the interviews. In shaping them for the film, he happens upon a compelling theory: that even in its still-born form, the film manifested the sort of collective conscious that Jodorowsky was trying to peddle through its plot, trickling down to influence other sci-fi films that followed. The evidence presented regarding details George Lucas may have stolen for “Star Wars” is unconvincing, though O’Bannon, concept artist Chris Foss and Giger did go on to collaborate on “Alien,” extending a relationship that started with “Dune.”

And it sounds like you get a pretty good sense of how the film would have gone, including storyboards and brief animated sequences. But Dune purists probably won't be pleased. According to The Hollywood Reporter:

Never troubled by anything resembling modesty or irony, Jodorowsky claims that he planned Dune as “the most important picture in the history of humanity”. In one of many unwittingly comic slips, he freely admits he never even read the novel and happily rewrote the ending: “I was raping Frank Herbert,” he grins, “but with love." ... However unreliable a narrator Jodorowsky may be, this documentary does a service to film history by making his lavish storyboards public, and even bringing some alive with brief animated sequences.

I thought his post threat performance was a nice callback to sentiments Tyrion shared in season 1, about always having to anticipate and preempt the way people would mock him, by doing it to himself.

YES! Very well said. But he's also clowning for his life here — he just threatened the King, and he's going to have to play VERY drunk to cover it up.

Holy crap, the writing and acting on Game of Thrones keep getting better. Last night's episode was both epic and understated, with small moments that carried huge weight. This was another episode all about rape (arguably, a key theme of the show) and yet it was smart and entertaining. Thanks, in no small part, to Peter Dinklage.

Spoilers ahead...

The major arc of the episode was two men deciding not to go along with rape culture. Tyrion Lannister disobeys his father and refuses to deflower his 14-year-old bride, Sansa Stark, until she actually consents to sex. Meanwhile, a merc with a mouth named Daario Naharis has a disagreement with his two colleagues, who really want to rape Daenerys and her female ex-slaves. Daario has his own idea of what is best in life: screwing women who want to screw you, and killing men who want to kill you. (Not so much with the lamentation.)

This show is full of gray areas of sexual nonconsent — Tyrion himself has sex with lots of sex workers, and we've seen Littlefinger tell his "employees" that if they don't perform with alacrity, they will be sold to one of his more sadistic clients. Daenerys herself had a wedding night that seemed at best ambiguously consensual, and in this episode she tells Missandei that she had to learn Dothraki quickly so she wouldn't just be "grunting" at her husband (while he kept taking her like a dog.)

In fact, in last week's episode, when Margaery tells Sansa that women in their position have to "make the best of it," she's basically saying "lie back and think of England." Because that shit is what this society is built on. If you're in the nobility, men like Tywin Lannister decide whom you make babies with.

And meanwhile, poor Gendry gets seduced — by wealth as well as by sexiness — so he can be tied up and have a leech put on his cock. (And he'll be lucky if that's the least that happens to him.)

Tyrion's self-loathing is not helping

This episode was just jam-packed with amazing (and subtle) performances — but hot damn, Peter Dinklage walked away with it. Throughout the episode, we're sympathizing with Tyrion's discomfort and misery — we're totally on his side — and yet, we can't stop seeing how much he's torturing Sansa, and how revolting his behavior seems to everybody watching.

Sansa is the opposite of the sort of woman Tyrion usually prefers: someone who's as cynical and mouthy as he is, someone who doesn't pretend that any of this crap matters. And she just radiates a sense of vulnerability, and Tyrion cannot protect her — as King Joffrey dramatizes by removing Tyrion's step ladder so he can't place the cloak of protection around her shoulders without lowering herself. It's not just that she's barely pubescent and he's been ordered to rape her — she's also exactly the sort of woman that Tyrion can't cope with. Sansa is a reminder of Tyrion's failures.

And so Tyrion reacts to all of this, not with a steady dignity or by trying to show his good qualities to Sansa — but with open, brutal self-loathing. When he gets a precious moment alone with Sansa before the wedding, he tells her that he didn't want this marriage either — but that comes across as rejection, not just as wanting to spare her. When he does compliment Sansa, it seems patently insincere, since he's just deflected her compliment by saying he's the husband of her dreams, with total sarcasm. And being his wife is "a different kind of prison." Way to rub it in.

A shrewd man would make an attempt at wooing his new wife, with a romantic speech about how he hopes she'll learn to love him in time — but Tyrion just puts it all out there.

And the actual wedding banquet is... what the hell. Tyrion gets drunk and starts acting out, putting his absolute worst face forward and making poor Sansa squirm, while all the wedding guests look on with pity and revulsion. The expressions Tyrion makes as he spills wine all over himself are amazing. And then he announces to his dad that he'll build a shrine to himself as the god of drunken lust at the next brothel he visits.

And after King Joffrey attempts to have Sansa dragged off, half-naked, for a "bedding ceremony" at which Tyrion will deflower her in front of everybody (and maybe the King will have a bit of droit du seigneur) Tyrion threatens to cut Joffrey's penis off. Which is probably a bit of a wedding faux pas. After that, all bets are off. Tyrion is forced to act even drunker than he actually is, to cover up the fact that he just threatened to castrate the King, and this leads to him babbling about his tiny penis and the fact that he once vomited on a sex worker mid-coitus. It's a performance that's both hilarious and heart-breaking, all at once — and yet, you can't escape seeing it through the eyes of the people watching.

But the bit where Shae comes in to bring the newlyweds breakfast and sees that the sheets have no blood on them, and just gives Tyrion a little smile — like, "okay, you don't totally suck" — is just brilliant.

Sell-swords, slaves and sex workers

So if Littlefinger will sell his girls to a horrible sadist (like he did Ros) if they don't perform properly, are they slaves? Not technically, no — Westeros doesn't have slavery, which is why Jorah Mormont was driven away from the realm and stripped of his titles.

And certainly Mero, the Titan's Bastard, seems to see sex workers and slaves as interchangeable. When he's taunting Daenerys, he pretends she was working in a pleasure house in Lys — the tongue thing is amazingly revolting — and also keeps threatening her with slavery and gang rape. Later, he's got a sex worker perched on his knee, and he doesn't treat her much differently than he does Missandei the translator.

And yet, Mero sees himself as a whore too — he sells his sword for gold, instead of his junk, but it's the same thing in the end. He's happy to degrade women whom he sees as exactly the same as himself. Because of course, they're not really the same, given that a sword in skillful hands carries a lot more power in this world. Mero doesn't degrade sex-workers and slaves to make himself feel better, he just wants to drag everyone down to his level so they can all lick his ass. It's a worldview built entirely on fellatio and analingus.

Daario has been a sellsword for a while, but he has a whole romantic view of himself as "fighting for beauty," and a whole ideology based around not paying for sex and only killing people who are trying to kill him. Beauty won't pay the bills, of course, and his fellow sellswords immediately tell him that he won't live long. Which, ha. And, as he tells Daenerys, he does what he wants to and he always has a choice — he won't become a slave, via the transitive property of treating others in his same station like slaves.

Daenerys' face during her two big scenes in this episode is amazing to watch — she doesn't flinch at all, as Mero is demanding to see her vagina. And then later, when Daario shows up with a sword when she's naked in the bath, she looks totally stone faced and asks if the severed heads of his comrades are supposed to impress her.

Her poker face has gotten incredible, and this is clearly an arc that began with her taking power in her relationship with Khal Drogo, by speaking his language and taking control during sex. (And her rise to political power really began with preventing Drogo's bloodriders from raping captive women.)

The juxtaposition of the Tyrion and Daario sequences is really fascinating, as both men rebel in very different ways against the imperative to take women by force — and somehow Daario manages to seem studly and awesome, while Tyrion appears a total fool. Even though Daario is actually kind of an underhanded bastard, who beheaded his own captains and broke the bond of their contract, and Tyrion is being decent and kind.

The whole tone of the episode is set by a debate between Arya and the Hound, who rejects Arya's claim that he's the worst man there is. His brother has killed a man for snoring, and there are plenty of men who would rape a girl as young as Arya — and in fact, the Hound saved Sansa from being gang-raped during the riot in Flea Bottom last season. (And Arya turns out to have misjudged the situation with the Hound anyway, since he's taking her to her family, not back to the King.)

Stannis' choice

The third man who faces a major choice in this episode is Stannis, who has just taken delivery of Gendry, the bastard son of King Robert. While Daario and Tyrion are trying to decide whether to follow orders, Stannis is trying to figure out what order to give — his priestess, Melisandre, wants to sacrifice Gendry because his blood has great power.

So Stannis goes to seek out his best advisor, Davos the Onion Knight, whom he locked in a dungeon for striking against Melisandre before. Davos has been teaching himself to read, thanks to Stannis' daughter Shireen — just like Daenerys taught herself Dothraki — and he's got some pretty good arguments about not spilling the blood of an innocent who's technically Stannis' nephew.

What it boils down to is, the difference between magic and religion once again. Davos says that Melisandre's god, like all gods, is just something we invented because we get scared of death in the middle of the night. And Stannis points out that Davos has seen stuff, including Melisandre's deadly smog baby, that can't be explained. But does that prove that she worships an actual god, or just that she has magic powers?

When Melisandre is in the middle of seducing Gendry, she talks to him about the difference between the fake chicken in the "brown stew" he ate in Flea Bottom and the real thing — like the fancy wine he's drinking now, you can tell the real thing right away because your tongue knows the difference. So it is with Melisandre and her god — you can tell immediately that it's real, because of some kind of metaphysical taste test.

And then Melisandre starts having sex with Gendry, ties him up, and leech-cocks him.

This bait-and-switch — happy intercourse replaced with leeches — is like a metaphor for religion generally, but it's also a kinder fate than Melisandre had in mind for Gendry until Stannis and Davos intervened. And it's interesting that in an episode where women and girls are threatened with violation that doesn't actually happen, the main violation happens to Gendry, just when he's starting to think he's been selected for something awesome.

Cersei is amazing

In an episode full of awesome performances — including Lady Olenna trying to figure out the tangled family tree that will result after her grandson and grand-daughter are married to mother and son — Cersei's scenes stand out. She goes for the jugular with Margaery, telling her a long and bloody story about the family that tried to challenge the Lannisters and ended up as a set of handy decorations for the wall of Casterly Rock. Margaery's poker face as she hears Cersei's hardly-veiled threats is not quite as good as Daenerys', but she keeps smiling and waving at people, and the scene is just bloody brilliant.

And the sad story of the Reynes of Castermere has been immortalized in a song, whose name incidentally is the title of next week's episode.

Later, when Loras and Cersei are standing alone, he tries to spark up a conversation, and she just slaps him down. She puts more into "Nobody cares what your father once told you" than a lot of people would into a whole smouldering speech.

And yet, Cersei knows she's losing her grip on Joffrey — to the point where, when she sees Joffrey heading off to torment Sansa, she actually tries to encourage him to talk to Margaery instead.

The themes of weird tangled families, patriarchy and rape come together in Joffrey, who tells Sansa that he's the "father of the realm" and thus a suitable substitute for her real father, whose head he chopped off. And his very next interaction with her is to threaten to have two knights hold her down while he puts a Lannister baby in her. It's pretty insane.

The kicker to the episode is Samwell Tarly, failing to make a fire and then discovering he can't fight and hold a baby at the same time, because he's not Chow Yun-Fat, unexpectedly destroying one of the White Walkers with that weird obsidian dagger he found at the Fist of the First Men.

This comes after Samwell and Gilly have a long talk over what to name her son, which sort of turns into what sort of patriarch they want him to take after. Not Craster. Not Samwell's father Randyll, who was cruel in his own fashion. Maybe Lord Jeor Mormont, except that Gilly doesn't realize Mormont is a family name — she doesn't understand the concept of "family name," where a father passes his name down to his children, because Craster was both the ultimate rapist and the worst patriarch, with no sons to carry on his name.
