Want to read the first research published from NASA's Mars Curiosity expedition? That'll be $20, per paper, for a one-day pass. Or, at least, that's how much it would cost you to read those reports through Science
, the journal that published them. Last Thursday, Michael Eisen, a biologist who founded the open-access journal Public Library of Science, put up a blog post in which he released free pdfs for all five of NASA's Curiosity papers
. Meanwhile, Mother Jones has a profile on Eisen
, which goes more in-depth into his campaign to make taxpayer-funded research more easily available to the taxpayers, themselves. — Maggie
Back in February, a Texas forensic scientist announced that she'd identified a DNA sample from Bigfoot and had sequenced the creature's genome. Now the sequences have been released for wider scrutiny and Ars Technica's John Timmer had a chance to dig into the data
and speak with the discoverer of the possible Bigfoot genome. This is a story that, I think, everybody can enjoy — a skeptical analysis that's respectful to the Bigfoot researchers and genuinely interested in understanding where the DNA in question came from and what the genome sequences can tell us. — Maggie

NASA JPL sends word today that image processing lab specialists have assembled a billion-pixel view from the surface of Mars, from NASA's Mars rover Curiosity. The 1.3-billion-pixel image is offered with pan and zoom tools here.
It's the first NASA-produced view from the surface of Mars at this resolution, and is stitched together from close to 900 exposures taken by cameras onboard Curiosity, revealing details of the landscape along the rover's route.
Here's a "manageable" download of the full image. More from the JPL news release, below.

Tonight is Yuri's Night — a holiday celebrating the first human spaceflight. You can throw a Yuri's Night party yourself, or simply join one of the 340 parties that are already scheduled
. Scheduled events range from the ubiquitous "let's drink vodka shots in a Russian restaurant" to more kid-friendly, telescope-centric themes. And this year, you can even virtually join the Mars Curiosity Rover as it throws itself the first Yuri's Night party to be held on another planet
. (Which, frankly, sounds a little lonely and sad, so hopefully people turn up for the virtual side of that shindig.) — Maggie
When one of Caroline Paul's cats disappeared for 5.5 weeks, it inspired her to find out what Tibula (the cat) was really up to when he left home. The process of this is pretty fascinating
. The outcome is, well, kind of cat like. What was Tibula doing when he wasn't at home? Avoiding the house and staring at himself in windows, apparently. — Maggie
The Rotating Snake Illusion is a fun image that makes your brain perceive motion where no motion actually exists. Psychologists understand the factors that make an illusion like this work (and work better) — for instance, breaking up and staggering the colored lines that radiate from the center of the circle creates a much stronger sensation of movement. But they don't know exactly why it works yet, according to Japanese psychologists Akiyoshi Kitaoka and Hiroshi Ashida.
And that brings us to this kitten video.
YouTube user Rasmus posted a video that he thinks might show his cat being tricked by the same sense of motion that catches the eyes of humans who look at The Rotating Snake Illusion. On the other hand, this just might be a cute video of a kitten attacking a piece of paper — which is known to happen.
So here's the challenge: Try it on your cat. You can print it off here. Then, report back here and/or post video responses to YouTube. Let's gather some data!
This is not exactly the soundest experimental methodology ever, but it sure would be interesting to see what happens.
Minnesota Public Radio is hosting a live Science Night on May 21st in St. Paul
, featuring John Grotzinger, the head of the NASA Curiosity mission. And I get to join him on stage to talk about outer space, Mars, and all sorts of awesomeness. If you're an MPR member, you can buy tickets now. Otherwise, they go on sale on March 12.
Just a few minutes ago, researchers with NASA's MESSENGER mission announced the publication of data that strongly suggests the poles of Mercury contain significant quantities of frozen water.
On the one hand, this is not exactly new news. The possibility of water on Mercury has been a topic of research for something like 20 years. And scientific discoveries tend to move in little mincing steps, not giant leaps, so there have been lots of previous announcements about evidence supporting the hypothesis of water of Mercury — including very similar announcements from the MESSENGER team in December 2011 and March 2012. Your life will not change in any significant way because there is frozen water on Mercury. You probably won't even make a note to tell your children where you were the day NASA announced that ice most likely existed there.
But that doesn't mean this news isn't damned exciting. And it doesn't mean that the scientists involved shouldn't be giddy about it. We are, after all, talking about a mission that sent a spacecraft into orbit around another planet and has quite likely found frozen water sitting on a landscape that is hot enough to melt lead. What's more, they think that ice is covered in places by a thin layer of some coal or tar-like organic material. That is huge news. It's going to change textbooks. And because the scientists think both the ice and the organic material got to Mercury via collisions with asteroids and comets, it's going to be an important part of our ongoing efforts to understand how life begins on planets like Earth.
All of this makes for a really nice, topical lead-in to an essay Robert Gonzalez published on iO9 today. It's totally reasonable to be frustrated by the recent whiplash of hearing that Curiosity discovered something "Earth-shattering" on Mars, only to have that announcement quickly revised to something "interesting" and/or "not insignificant". But, Gonzalez argues, it's also reasonable for scientists to look at something that is merely not insignificant from the public perspective and see it, from their own perspective, as groundbreaking. In fact, he says, we want more scientists who get excited about their work, not fewer.

What might the Curiosity rover find on Mars? So many cool things. Maybe friends that hug your face! Maybe Nixon's secret tapes! Or maybe even something less easily fit into song lyrics, like significant amounts of Martian methane.
This video, made by Cinesaurus, is a parody of "Dumb Ways to Die", an adorably demented public safety message from Australia's Metro Trains Melbourne. If you've not seen that yet, you should check it out as well.

Just before Thanksgiving, the lead mission scientist for the Curiosity rover told NPR that his team had found something that would "be one for the history books." Naturally, we all began speculating about the presence of life, giant obelisks, and half-buried Statues of Liberty
. Yesterday, however, a different NASA spokesman basically asked the world to not get its hopes up too high, revising the level of importance down from "earthshaking" to "interesting"
. So far, nobody has said what, exactly, was discovered. (Via Colin Schultz) — Maggie
The Curiosity rover comes complete with a mini chemistry lab. It's designed to analyze the composition of Martian soils and Martian air. And, right now, that particular piece of equipment is at the center of a giddy storm of activity. Curiosity has turned up something important — big enough for Curiosity's principal investigator to tell NPR, "This data is gonna be one for the history books."
What is it? NASA's not telling just yet. Right now, researchers are in the process of verifying said exciting data, in order to make sure they aren't deceiving themselves into thinking they've spotted something that isn't really there. That's pretty good policy, given the recent flap around over-hyped studies about Earth-like planets and arsenic-based life.
On the other hand, if you're trying to avoid overhyping something, might I suggest that "We have groundbreaking, world-changing data that we can't tell you about yet," is maybe not the best way to do it.

This video interview with Ashwin Vasavada, Deputy Project Scientist of the Mars Science Laboratory, is a nice overview of the what everybody's favorite currently operational Mars rover is looking for.
When a narrow stream, flowing downhill, meets a wide, significantly-flatter valley, you get an alluvial fan — a place where the flow of water spreads out, slows down, and leaves behind all the rocks and sediment it's no longer moving fast enough to carry. At least, that's how it works on Earth.
Once upon a time, it may have worked that way on Mars, too. Yesterday, NASA announced that the Curiosity rover had documented geology that looks very much like an alluvial fan and rocky deposits that also look very much like what would be left in an alluvial fan on Earth. You can see the comparison of some of those in the image above. In these Martian geological features — as in an Earth-bound stream bed — you find smooth, rounded pebbles and conglomerates, masses of pebbles cemented together over time. The rocks photographed by Curiosity are also too large to have been blown into this sort of arrangement by the wind.
All of this adds to the long string of evidence that Mars once had flowing water on its surface. In fact, reading up for this post, I was surprised to see how much evidence there actually is for this, some direct and some indirect, stretching all the way back to the Mariner 9 orbiter mission in the early 1970s. And, of course, there is water on Mars right now. It's just not flowing water. Previous probes have measured a small amount of water in the Martian atmosphere, and the planet's polar regions contain both frozen carbon dioxide and frozen water. Viking 2 took pictures of frost on the ground in the late 1970s, and in 2008, the Phoenix lander literally dropped out of the sky onto a patch of ice.

I'm sitting in on a NASA Jet propulsion laboratory teleconference for science journalists, with an update for the world on the Mars Curiosity rover's mission. Curiosity completes her "checkout" phase today. Including an "intermission" of 13 sols, and one remaining sol to inspect the rover's robotic arm, 26 sols have been devoted to so-called checkout duties. Today is sol 37. Rover is currently facing a Southeast direction. Temperatures on the rover are between 7 and 33 C. She has covered a little over a football field's distance on the surface of Mars. Ability to move the arm has been confirmed, and the ability of the rover to perform sampling is confirmed.
Curiosity has so far driven 109 meters from its original landing site, and engineers are driving her about 40 meters per sol. The first drilling into the surface of Mars is expected to occur about a month from now, following various surface activities (scraping rock surfaces, and so on).
Three speakers in the teleconference: Jennifer Trosper, JPL; Curiosity mission manager. Ralf Gellert, University of Guelph, in Guelph, Ontario, Canada; principal investigator for the Alpha Particle X-Ray Spectrometer instrument (or APXS) on Curiosity. Ken Edgett, Malin Space Science Systems, San Diego; principal investigator for the Mars Hand Lens Imager (or MAHLI) on Curiosity.
