There's a photo of a recent en-caul birth making the rounds online. The photo is being attributed to Greek obstetrician Aris Tsigris. It's fascinating. But it's also pretty graphic, so fair warning on that. (If the sight of newborn infants and blood gives you the vapors, you might also want to avoid most of the links in this post, as well.)

Check that shit out. I mean, seriously. That's awesome.

There doesn't seem to be a lot of information on the details of this particular birth, but, most of the time, when a baby is born this way it's also born premature. Sometimes, really premature. There are case reports in medical literature of babies being born en-caul at 23 weeks, 6 days gestation, which, for context, is a little over half the weeks you'd want a baby to gestate. Fetuses aren't large or well-developed enough to even be able to clearly tell their sex on an ultrasound until about 20 weeks gestation.

The premie connection is probably more than coincidence. For one thing, the smaller the fetus, the more space the sac around it has to ballon outward and come through the birth canal intact. What's more, there's evidence that being born en-caul has a protective effect for premature infants. Nobody is exactly sure why. But it might have something to do with the physical mechanics of birth, which, I'm sure you're aware, can be a little rough on both mother and baby. Premies born en-caul essentially come with their own cushiony air bag, which might protect them from physical injuries that could otherwise be life-threatening.

So, in that sense, babies born en-caul really are lucky. Just not in the way the ancient legends would have you believe. In fact, in 1975, a newborn survived for 25 minutes outside the uterus, but inside the fluid-filled amniotic sac, not breathing air, and turned out completely healthy.

Speaking of legends of the caul, back in 1952 The Yale Journal of Biology and Medicine published a manuscript by Thomas Forbes, which collected literary and documentary references to caul-related superstitions dating back to Roman times. I wanted to share one particularly fun story from Forbes' account. This refers to a caul birth, rather than an en-caul birth, so the amniotic sac wasn't totally intact. Instead, just a part of it was draped over the newborn baby's head.

Notes and Queries, that extraordinary repository of antiquarian and other information, offers a quotation from a British newspaper, the Leeds Mercury, for 14 September 1889.

"A laborer's wife bore a son on whose head was a caul. The veil was placed on one side, and no notice was taken of it until some hours after the child's birth. When examined, however, it was found that the words 'British and Foreign Bible Society' were deeply impressed upon the veil. When this discovery was made the greatest excitement prevailed in the neighbourhood, some of the women declaring that nothing short of a miracle had been enacted. The doctor, who inquired into the matter, however, soon explained the affair. The veil, whilst in a pliable condition, had been placed upon a Bible, on the cover of which the words 'British and Foreign Bible Society' were deeply indented. The words were in this way transferred to the veil; but some of the inhabitants still ascribe the affair to supernatural influence..."

Two things I learned from this video:
1: I am my cat's Facebook page. That rubbing-up-against-you-and-leaving-scent thing? It's not just to mark you as "theirs". It's also a way of communicating information about themselves to other cats that you might encounter.
2: My cats poop in a box and bury it as a gesture of submissiveness to me. Good cats.

Minute Physics tackles the greatest mystery in all the Internet and solves it with the power of science (and pedantry).

UPDATE: Reader Pat David went the extra mile and improved the trailer a different way: by keeping the music and sound effects but removing the dreadful voiceover: "turns out it's a center-panned vocal - so just inverted the LR stereo channels." Pat's edit is pasted above, UberWaz's is below.

After years of waiting, Alien fans were shocked yesterday by the appalling state of the trailer for Aliens: Colonial Marines. Badly-acted and terribly-scripted, it made the forthcoming game look amateurish and cheesy; the project's lead writer immediately and publicly disowned it. But what a difference a day makes: Rock Paper Shotgun reader UberWaz remixed the clip with new audio, creating something that perfectly matches the franchise's gloomy mix of science fiction and horror.

Here's the "fixed" trailer using the original Aliens soundtrack as a mood piece. Below is the excruciating, official original.

This is actually a real life animal.

I know. I didn't believe it either. When it turned up in my Facebook feed, via my Aunt Beth, I assumed that this had to be a hoax photo. Had to be. I mean, just look at it. This animal looks like it should appear in pretty photos forwarded to you by your aunt that later turn out to be the result of a photoshopping contest on Something Awful, right?

But then it was on Wikipedia, too. And I thought, "Okay, it's still the Internet. Somebody is clearly just getting really elaborate in their trolling."

And I suppose that's true. If by "somebody", what I mean to say is "natural selection".

This is the Glaucus atlanticus. It is a type of nudibranch—shell-less mollusks known for their extravagant shapes and colors. It is venomous. And I am now almost completely convinced that it's not a joke.

The London Natural History Museum has some good information about these creatures, including the drawing at left, which was made in the late 1700s by Sydney Parkinson, the official ship's illustrator for Captain Cook's second voyage to the Pacific.

You see all those pointy bits Glaucus atlanticus? According to the Natural History Museum, those are called cerata. They are the organs where G. atlanticus stores the stinging cells that it steals from the jellyfish it eats.

Because it eats jellyfish. And not just any jellyfish—but Portuguese Man o' War jellyfish. G. atlanticus eats the jellyfish tentacles and, as part of the process of digestion, stores stinging cells from those tentacles in the tips of its cerata. Then G. atlanticus gets to be venomous, too. Fun! Sharing!

Here's how the Smithsonian Magazine blog described the process last Spring:

A gas-filled sac in the stomach allows the small slug to float, and a muscular foot structure is used to cling to the surface. Then, if it floats by a man o’ war or other cnidarian, the blue dragon locks onto the larger creature’s tentacles and consumes the toxic nematocyst cells that the man o’ war uses to immobilize fish.

The slug is immune to the toxins and collects them in special sacs within the cerata—the finger-like branches at the end of its appendages—to deploy later on. Because the man o’ war’s venom is concentrated in the tiny fingers, blue dragons can actually have more powerful stings than the much larger creatures from which they took the poisons.

In conclusion, there are two lessons to take away from G. atlanticus.
First, the Internet isn't always lying to you. Just sometimes.
Second, don't touch things that look pretty. Because they will probably kill you.

Well, it's been a quiet week in Minneapolis, Minnesota, my hometown. The heatwave broke. There was a giant tomato fight downtown. And the Gonzo Group Theater is performing Aristophanes in the middle of the lightrail construction zone. But out on the Internet, everybody is talking about the fact that Minneapolis will, on August 30, play host an Internet cat video film festival.

Yes, a film festival of Internet cat videos. Curator Katie Czarniecki Hill is accepting nominations through July 30, so you should totally submit your favorite.

But I also wanted to talk briefly about the context of this, because it's awesome, and you should know about it. Czarniecki's Cat Video Film Festival is part of a summer-long program at the Walker Art Center (our fabulous modern art museum) called Open Field. If you're not familiar with Minneapolis, the Walker sits at the base of a big hill. Part of the lot is covered with art museum, and part of it is given over to a broad, grassy slope*.

That's where Open Field happens. What's Open Field? Partly it's just a reminder that this big public greenspace exists behind the Walker and, hey, maybe you should come hang out there. But it's also sort of an ad-hoc, crowd-sourced, summer-long festival space, where both Walker artists-in-residence and average folks can stage unique community events, skill-shares, workshops, and projects. Today, for instance, you could go down to Open Field and team up with a group of knitters and fiber artists who are building an interactive fabric installation; join the band Dear Data for a low-key acoustic campfire sing-a-long; watch your own (and other people's) old, film-based home movies and learn about film preservation; and participate in an interactive workshop about the history and future of print-letter writing and the post office.

Basically, you should know this—Walker Open Field: It's like a Happy Mutant smorgasbord.

Let's be clear. Michael O'Hare is not the Zodiac Killer. He's got a pretty good alibi—namely the fact that he was nowhere near California when the murders happened. In fact, his name only entered the field because an enthusiast named Gareth Penn analyzed some of the famous Zodiac cryptograms and somehow came up with the name "Michael O". How that led Penn to O'Hare isn't exactly clear, but however it happened, Penn has spent the last 30 years telling anyone who will listen that Michael O'Hare is the Zodiac Killer.

And that has made O'Hare's life rather ... interesting. This weekend, I ran across a 2009 essay, written by O'Hare, describing his experience as the unwitting subject of somebody else's conspiracy theory. This is old, but I wanted to share it because it's such a rare perspective on this kind of thing. In the age of the Internet, it's easy to read up on conspiracy theories covering just about any topic. For most of them, you can also find extensive debunking sources. It's much less common for somebody at the center of the story to talk about what that experience has been like. Totally fascinating.

The decades since Penn fixed his sights on me have not been a living hell, much as that would spice up this story. They have been an ordinary life, punctuated by one or another flurry of fuss from Penn, sometimes involving pages of numbers (for example, the data pages from my PhD thesis) with this or that sequence picked out, circled, and "decoded" into words that fit somehow into Penn’s model of the crimes.

My favorite episode was the phone calls. Sometime in the 1980s, I started getting them at two and three in the morning. When my wife or I answered, a male voice would say something vaguely threatening like "I’m coming north, and I’m going to get you soon!" .... The calls were supposed to be transmitting coded messages via numbers—in particular, the time of the call! Apparently, Penn’s assumption was that when the average person is aroused by the phone in the middle of the night, the first thing he does, before woozily answering, is to note the time of the first ring on the digital clock he keeps by the bed—which is, of course, synchronized with the clock in the Naval Observatory. If your clock (or his) is off by just a couple of minutes, the call that was supposed to register as "2:14"—code for "Got you dead to rights this time"—will be misinterpreted as "2:16," which I think means "The Sox can’t make the playoffs without a closer." (Sadly, I’ve lost the magic decoder ring I got in exchange for cereal box tops as a child, so I can’t be sure.) The story got even better years later, when I discovered that a Penn skeptic had been calling him at home at times that figured into Penn’s theory, whereupon Penn assumed the calls came from me and "returned" them to my house, so he thought he was having a conversation with me, all in three-digit numbers.

For the next 60 years or so—basically, until everyone roughly my age has died off—former Alaskan senator Ted Stevens will be widely remembered (and mocked) for once describing the Internet as "a series of tubes".

But here's the thing. It's easy to make fun of Ted Stevens. It's harder (much harder) to explain quickly and at a relatively simple level—for lay people with no tech background—what actually happens when they call up a web page.

That's why Greg Boustead and the nice folks at the World Science Festival put together this short video, explaining the basics of the Internet, specifically the basics of packet switching. The video should help the average person understand the Internet just a little better and it has been run by several experts for accuracy, Boustead says.

I have to admit that when I had to screen it for "father of the Internet" Vint Cerf, who invented this process, I was more than a little nervous, certain he would pick it apart. When he replied with "This is so good - can I please use it to explain the concept of packets at public lectures," needless to say, I was over the moon.

So, the Internet. It's not a big truck. It's not a series of tubes. It's more like a bus full of tourists.

What a steaming turd of an opening line in David Streitfeld's otherwise serviceable New York Times piece about the Ellen Pao/Kleiner Perkins sexual harassment lawsuit, and gender discrimination in Silicon Valley.

Here's the opening graf (bold-ing, mine):

MEN invented the Internet. And not just any men. Men with pocket protectors. Men who idolized Mr. Spock and cried when Steve Jobs died. Nerds. Geeks. Give them their due. Without men, we would never know what our friends were doing five minutes ago.

You guys, ladies suck at technology and the New York Times is ON IT.

Radia "Mother of the Internet" Perlman and the ghosts of RADM Grace Hopper, Ada Lovelace and every woman who worked in technology for the past 150 years frown upon you, sir. Women may have been invisible, but the work we did laid the groundwork for more visible advancements now credited to more famous men.

"Men are credited with inventing the internet." There. Fixed it for you.

I ragequit this article like, 10 times, and couldn't get past that awful opening line. But eventually, I managed to put down my frying pan and unbunch my apron, and I sat down on my princess tuffet and asked a man to help me read the whole thing.

I appreciate that in this article, Mr. Streitfeld is advancing a public conversation about gender inequality in the tech industry. Reporting about a phenomenon many would prefer to deny, and including women's voices in that conversation (though many of them sound too afraid of retaliation by potential male funders to be candid)—that's a good thing. Pointing out how rare it is that this sort of sex discrimination lawsuit makes it to trial is also a good thing.

I know that headlines aren't always written by the reporter, so I can't fault Streitfeld for the abominable one used for this article in the Times print edition: "A Lawsuit Shakes Foundation of a Man’s World of Tech." Go ahead, throw up in your mouth a little. I did.

I know that photo captions aren't always written by the reporter either, so I can't fault him for the lack of logic behind this one:

Ellen Pao, a partner at the venture capital firm Kleiner Perkins Caufield & Byers, has filed a lawsuit contending sexual harassment. The suit has surprised some people in Silicon Valley because Kleiner Perkins is among relatively few such firms there to routinely hire and promote women.

Well, duh. If a VC firm does not hire any women VCs, then there are no women VCs at the firm to sexually harass.

There's a lot of other interesting but to my mind, tangential stuff in the body of the piece about the sexuality of Ms. Pao's husband, and accusations of litigiousness and sexual harassment on his part. And, a sweet but even more tangential quote from his ex-boyfriend, who sounds like a real mensch with a kind heart. I'm not sure why an accounting of the behavior of a woman's husband is so often needed to tell the woman's story. The reverse is not common.

But the unchallenged dismissiveness of this quote is, for me, the kicker:

You don’t really hear about randiness and mistreatment of women. That doesn’t prove it’s not there, but that’s not the lore.”

The LORE? Are you fucking kidding me?

I worked in Silicon Valley, and in technology startups in other regions, and have experienced sexual harassment and gender bias. It's as normal and constant a part of the landscape as the fabled foosball tables.

Where to begin with this quote, really? First, "randiness" isn't what causes sexual harassment. Men don't pressure junior female co-workers into unwanted sex because they're "randy." And the fact that it's not in the fucking "lore" doesn't mean it's not real.

I have no special knowledge about the truth, or lack thereof, in the Pao lawsuit. I know only what you and I and everyone else can read in the court documents, in the context of what I've experienced as a woman who has worked in the technology industry for about 20 years. I can't speak to the merit of this case. But, Earth to dudes: yes, this stuff is real and normal, and so are we.

Lucky for Streitfeld, and the rest of the world, that the Women in Technology conference happens to be under way today in Santa Clara. Stop by and get a clue.

Oh, and? I, too, cried when Steve Jobs died. And I still idolize Mr. Spock.

The Moscow-based security firm credited with solving various mysteries around Stuxnet and Duqu today announced the discovery of Flame, a data-stealing virus said to have lurked on thousands of computers in the Mideast for as long as 5 years. A Kaspersky Lab spokesperson described it in a Reuters interview as "the most complex piece of malicious software discovered to date."

Adds Bruce Sterling, "Given that this has been out in the wild for a couple of years now, what’s five times bigger than 'Flame' and even less understood?"

Writing today at Wired News, Kim Zetter reports that Flame is believed to be "part of a well-coordinated, ongoing, state-run cyberespionage operation."

Kaspersky has a FAQ about Flame, here.

Marvin Ammori's recently-bestowed freedom bling. Note the Nyan Cat.

Constitutional law expert Marvin Ammori, one of the First Amendment scholars along with Larry Tribe who explained how SOPA would violate the First Amendment, shares a wonderful story with Boing Boing. Snip from his blog post:

When I was quite young, I saw the first Star Wars movie and believed that, if I took part in a great cause, it would end with a medal ceremony and a princess conferring the medal. It has finally happened.

Last night, I received a medal from Princess Tiffiniy Ying Cheng of Fight for the Future, representing the “committee for the Defenders of the Internet.” Bestowed upon me was the Nyan Cat Medal of Internet Awesomeness, the “highest honor known to Internet Defenders.” I could not be more honored.

Princess Tiffiniy’s organization was one of the leaders in the Battle of SOPA. She and her partner Holmes Wilson are pretty amazingly brilliant–they were the people who organized the Free Justin Bieber campaign, led American Censorship Day on November 16, and were among the leaders organizing the January 18 Blackout. Many people pulled together from an array of communities to fight SOPA–Redditers, Wikipedians, civil libertarians, entrepreneurs, artists, venture capitalists, tech executives, consumer electronics makers, tech bloggers–alongside millions of people who just love the Internet and hate Internet censorship, from technologically advanced Wookiies to technologically challenged Ewoks. Many awesome people were involved in leading, coordinating, and taking the time to fight SOPA.

Every now and then, I get a glorious reminder of just how much the Internet has enriched my life. Fifteen years ago, if I had arrived at a conference center—as I did yesterday for my stint in the Marine Biological Laboratory Science Journalism Fellowship program—and seen a sign in the lobby announcing the presence of a "Xenopus Workshop" I could have, eventually, found out that a Xenopus was a frog frequently used as a model animal in medical research.

Thanks to the Internet, though, I was able to learn the following things in a remarkably short period of time:

Xenopus Fact: Xenopuses (Xenopodes? Xenopi? Freshman Latin was a really long time ago, you guys) were used in one of the earliest reliable pregnancy tests. That's because exposure even a tiny amount of the hormone human chorionic gonadotropin will cause a female Xenopus to lay eggs. Inject a female Xenopus with urine from a human female and, if the Xenopus lays eggs, it means the female human is knocked up.

Xenopus Fact: You know how some lizards can grow a new tail if you cut the old one off? Xenopuses can do that with the lenses of their eyes.

Xenopus Fact: Because Xenopuses are so widely used in laboratories, there's a whole industry of suppliers of Xenopuses and Xenopus accessories. Case in point, the "Xenopus enrichment tube" in the photo above—apparently, they like to have something to hide out in. Also, you can buy synthetic slime to replace your Xenopus' natural protective coating that is often lost through frequent handling.

Web startups are made out of two things: people and code. The people make the code, and the code makes the people rich. Code is like a poem; it has to follow certain structural requirements, and yet out of that structure can come art. But code is art that does something. It is the assembly of something brand new from nothing but an idea.
