There have been a lot of changes lately in this telescope tourist’s life. Two big changes dwarf the others, and gave rise to lots of little fractal-like changes of their own: I started my first real, non-internship job covering space and physics for Wired.com, and I moved from the east coast to Seattle.

To get to Seattle, two of my dearest friends and I packed everything we could fit into my tan Toyota Camry and drove literally from ocean to ocean. (We drove an extra two hours on the last day to make sure we put our feet in the Pacific, since Seattle’s not actually on the coast.) We stayed with friends, took a couple hundred pictures, and drank more varieties of beer than I had thought possible. We swam in lakes, rode horses, and played a green ukulele around a campfire. It may literally have been the time of my life.

Kristine's poems "Illinois" and "Montana" displayed at Gimme! Coffee

I planned a few science writing trips along the way — our visit to the historic Yerkes Observatory was featured on Wired last month, and there are more to come.

But one of my road buddies, Kristine Heiney (pictured above, in the Badlands of South Dakota), kept a much more powerful record: She wrote poems. And she’s getting some recognition for them. Thirteen of her poems (two from the road trip) will be hanging in Gimme! Coffee in Ithaca, New York for the entire month of November. If you’re anywhere near Ithaca, go check them out! They even have some science in them.

In case you’re not going to be anywhere near Ithaca in November, Kristine said I could post the whole set of poems here. I can’t think of an introduction that would do them justice, so I’ll just let you go read them. They’re the best record I have of what those days felt like.

Back in February I wrote a feature story about research by Sapna Cheryan at the University of Washington suggesting that the geeky stereotype of computer science could be keeping women out of the field.

The basic idea is that people can tell whether they’d fit in a given environment–a club, an office, a stranger’s home–based only on the stuff they find lying around. Severely geeky stuff (the study singles out Star Trek memorabilia, comic books and energy drinks as examples) calls up the image of computer scientists as nerds with no social skills who have better things to do than shower, and makes the majority of girls (and significant numbers of boys) think, “I wouldn’t like it here. I’d better go somewhere else.”

Cheryan tested the theory by putting students in either a geekily-decorated room or a neutrally-decorated room, and asking them how interested they were in computer science. Women reported way less interest when they’d spent time in the geek room. The study has been through several different incarnations, but every time, women steer away from the geeky environment.

It’s a pretty bold claim, and bound to anger some people. My first reaction (and I know I’m not the only one) was something along the lines of, “Wait a sec, I’m pretty feminine, and I’m a gigantic nerd. Are you saying geeky and femme-y are mutually exclusive?” Well, no, Cheryan says–it’s just that the only women who are ending up in traditionally geeky fields already identify with geekiness. Plenty of technically-minded people might enjoy coding but don’t want to join geek culture, and that ought to be allowed.

My feature was published online in August, along with a video and a podcast, but the actual peer-reviewed research paper wasn’t published until this month. That meant I got to write it up again as a news story for Science News, which was fun. But it also meant a flurry of stories from reporters and bloggers who clearly didn’t read the paper.

The most egregious offender is io9, which is like Gawker for science fiction. The first clue that they didn’t do their homework is here:

Add to that the loads of biases that seem to have been jammed into this study (like the idea that liking science fiction is “masculine” and science-fiction toys are automatically a boys-only thing) that it’s hard to take it seriously.

A look through the paper makes it clear that whatever biases crept into the study came from the subjects, not the researchers. Cheryan and her colleagues asked a group of undergrads to generate a list of things they associated with computer science, and then asked a different group of undergrads to rate each object on that list on how computer science-y they found them. Only the objects that got high enough geek ratings made it into the room.

Then Cheryan et al asked the subjects in the actual study–another group of undergrads, at a different university–to rate the objects on how masculine they found them, as well as how much they associated the objects with computer science and with themselves. None of this stuff is researcher bias–it’s genuine cultural bias.

But my bigger complaint is their assertion that “women who are interested in computer science will be, ipso facto, geeks, and that means they’ll be interested in geeky stuff.” That’s exactly the point. The entrance fee to a computer science career is membership in geek culture, and that’s way too restrictive. If any other field had a cultural barrier to entry like that, no one would stand for it.

The writers at io9 don’t seem to care that they’re excluding non-geeks–“Do you really want to attract English majors to computer science?” Comments on my feature when it showed up on Hacker News two weeks ago took a similar tone, worrying that letting in non-geeks would degrade the quality of the code, or mean less code gets written. “Socially mainstream means leaving work at 5pm and going to the pub, that’s what “normal” people do,” says one commenter.

Honestly, I fail to see how this sort of argument differs from asserting that black people are lazy or Latinos are stupid.

And this attitude means that not only are non-geeks missing out on tech careers, the tech industry is missing out on a diversity of ideas and perspectives.

That’s not just a women’s issue. That hurts everyone.

First Exoplanets Dude

If hypothetically you knew a science writer who was going to interview the guy who discovered the first extrasolar planets, what would you want her to ask him?

The story is for Wired’s “This Day in Tech History” section, for April 22, the day the paper in Science confirming the existence of three planets around pulsar PSR B1257+12 came out in 1994. So I can really ask him anything. What did you have for breakfast that day? What did your mom say when you told her?

So what do you want to know?

Those of you living in the Bay Area probably already know that on Thursday, April 9, vandals hacked up 10 fiberoptic cables and disabled landline, cell phone, and internet service in Santa Cruz and Santa Clara counties for nearly 24 hours.

The vandals lifted 300-pound manhole covers and climbed down into underground vaults to get at the cables. They cut the cords in two different locations in about two hours. Clearly they thought about this a lot.

There’s been a lot of discussion about whether the communication system is secure enough, how dependent we’ve all become on our cell phones (a few of my classmates went out for lunch after class, and we struggled mightily to figure out how we’d find each other downtown if we couldn’t call), and what’s going to happen to the culprits when they’re caught.

But David Perlman, the 90-year-old science editor at the San Francisco Chronicle and a legend in his own time, used the crisis to teach some science. His article on today’s Chronicle is about the history of fiber-optics. He tracked down the guy who invented fiber-optics in the first place, Narinder Singh Kapany, now 80 and living in Palo Alto, and gave a sharp, vivid description of how it all works:

Today’s fiber-optic cables are bundles of dozens of single hair-thin strands, each fiber made of highly purified glass – often pure silica – and coated in a cladding of impure glass that holds light beams inside. A single cable, about 4 inches thick, has the capability to hold dozens of fibers, which can carry pulses of light signals as far as 200 miles – either curving or in a straight line – at about two-thirds the speed of light. Inside each fiber, the light’s “message” is reflected again and again at an angle against the fiber’s wall as it travels along.

That’s something I never really think about: our society runs on beams of light. Every time I check my email, call my mom, or buy groceries with my debit card, I’m sending a signal down a glowing cylinder that illuminates places no one ever sees. It’s nice to be reminded of the beauty in the mundane.

When Barack Obama took his presidential oath on January 20, a piece of the Mars rovers was there to commemorate it. Sort of.

obamamarsAbout a year ago, two scientists from NASA Ames and Carnegie Mellon decided to bring the Mars Rovers’ panoramic photo capabilities back to Earth. The resulting gadget, called a Gigapan, is a robotic camera tripod that pans and tilts to automatically take enormous photos. I wrote about it about a month ago (also on January 20, coincidentally) for my internship at SLAC Today and symmetry–the webmaster at the Exploratorium took some pictures of SLAC’s linear accelerator. They’re extraordinary. You can click on any point in the image and zoom in almost indefinitely without losing resolution.

The picture above was taken by photographer David Bergman. You can find the fully zoomable Gigapan image here; NASA reported the history of the photograph here. According to the article,

You can see Hilary Clinton’s white earrings, Barbara Bush’s fuzzy black earmuffs, the word “Obama” stitched on spectators’ winter hats, Yo-Yo Ma taking a picture with his iPhone…

It’s so poetically satisfying. The Mars rovers (now in year five of their 90-day mission) are a perfect symbol of tenacity, resourcefulness, and progress that actually works. Let’s hope Obama can do the same.

Dance Your Thesis

Okay, forget writing. ScienceNOW’s John Bohannon just showed me an infinitely superior medium for science communication: interpretive dance.

These folks are from a biochem lab at Louisiana State University, and they just won ScienceNOW’s “Dance Your PhD” contest in the Professors category. The dancers are professor Vince LiCata and his grad students, and they’re performing LiCata’s 1990 thesis, “Resolving Pathways of Functional Coupling in Human Hemoglobin Using Quantitative Low Temperature Isoelectric Focusing of Asymmetric Mutant Hybrids.” (Say that three times fast.)

They’re basically showing how oxygen binds to hemoglobin in different ways, depending on where the first oxygen molecules latch on.

Hemoglobin, a protein that transports oxygen around your blood, has four subunits, which tend to pair off into near-inseparable dimers (the pairs with matching gloves and goggles in the dance). If one dimer gets two oxygens (white balls) all to itself, it doesn’t cooperate well with the other dimer. But if each dimer gets an oxygen, they dance happily together, and usually pick up two more oxygens.

LiCata had to cool the molecules down and take pictures of them to study them–which explains the bearded “Old Man Winter” sprinkling “snow” and the paparazzi snapping photos.

This is my other favorite: grad student Sue Lynn Lau dancing her thesis, “The role of vitamin D in beta-cell function.” The sun produces vitamin D, vitamin D (Lau herself as the Sugarplum Fairy) delivers marshmallow glucose to somnolent beta cells, and the beta cells wake up and blow soap bubbles of insulin. Then they all dance around and the sun does four consecutive backflips.

Look how much fun they’re having! There should totally be more of this.

And there will be–the prize for the contest is to have your dance performed by professionals at the AAAS meeting in Chicago in February. I will definitely write about it, I promise.

For now, though, I need to go trade my laptop for a leotard.
