A Solar Impulse aircraft takes off at Payerne airport May 24, 2012, piloted by André Borschberg. The Solar Impulse HB-SIA prototype aircraft, which has 12,000 solar cells built into its jumbo-jet-sized wings (about 200 feet long), attempted its first intercontinental flight from Switzerland to Morocco with a few days for a technical stop and a change of pilot in Madrid. This flight will act as a final rehearsal for the 2014 round-the-world flight.

Here's a story that combines two favorite bits of volcano news into one interesting discovery. You know those great, freaky photos of volcanic lightning? (In case you don't, I've got one posted above.) Remember how the Icelandic volcanic eruptions totally screwed up everybody's airplane travel plans?
Apparently, studying volcanic lightning could lead to better eruption detection systems that could make it easier to predict how big a plume of ash off that volcano will be—knowledge that can help airlines and travelers be better prepared. At Nature, Richard Monastersky reports:
The researchers found that the amount of lightning correlated with the height of the plume, something they could not test using more limited data collected during an eruption at Alaska’s Mount St Augustine in 2006. This observation is important, says Behnke, because systems to monitor lightning could provide an estimate for the size of an eruption, which is not always easy to assess for remote volcanoes.
During a previous eruption at Mount Redoubt in 1989 and 1990, for example, the size of the plume wasn’t known and a plane nearly crashed after passing through the ash cloud and temporarily losing all power from its engines. Behnke and her colleagues suggest that VHF stations similar to the ones they installed at Mount Redoubt could be used to monitor volcanoes to give early warning of an eruption and an estimate of its size.

Seventy-one feet above the Harvard Forest, you can stand on a plywood platform attached to a slightly swaying tower of metal scaffolding, and look out over miles of hemlock groves. On the ground, the trees are massive—trunks reaching up and up and up. From the top of the tower, though, the view feels a bit like hanging out in a Christmas Tree farm. All you see are the friendly, conical tops.
The Hemlock Eddy Flux Tower is one of four research towers in the Harvard Forest. Since 2001, data collection systems on the top of this tower have measured carbon dioxide, water vapor, and wind currents. These measurements are made five times every second.
Thanks to this system, we now know that even a relatively old forest like this can still capture and store a decent amount of carbon dioxide. The hemlocks around the tower are pushing 230. That's not terribly old by tree standards, but it's old for this part of North America—most of which was once clear cut. It's also old enough to challenge some previously held conventional wisdom about what kinds of forests are best for carbon sequestration. Previously, scientists thought only young forests, where the trees were still growing rapidly, did that job very well. Sites like the Hemlock Tower have shown a different story.
Also: It's rather terrifying to climb. The tower lives, it is not stationary. A network of steel cables keep it from toppling over, but you can still feel it tilting one way and then the other underneath you. And, at every landing on the stairs, there's a precarious little gap you have to step over. I took my camera with me in one hand as I made the ascent. About partway up, the filming quality takes a notable turn for the worse as I found myself clinging a bit more tightly to the hand rails. How's that for an awesome tool of science?
Celeste Kidd from the University of Rochester writes in with news of a new study on PLoS One, which attempts to quantify the amount of stimulus that is optimal for amusing and engaging babies:
This video discusses the results of eye-tracking study we recently did at the University of Rochester that explains how babies organize their search for information in the complex world (and thus make their learning process much more efficient). The findings suggest infants look away from experiences that are either overly simple (and thus contain no new information from which to learn), or overly complex (and thus too overwhelming to learn from efficiently).
Infants in the study reliably preferred scenes that contained just the right amount of information--that is, those that were a little bit, but not too, surprising. We dubbed this attention pattern the "Goldilocks effect". These findings could have broad implications for human learning at all ages, and we hope the research will facilitate the development of more effective educational policies and diagnostic tools for attention-related
disabilities (such as ADHD and autism).
Also important, especially for parents and teachers, is the fact that this study demonstrates that the same response--namely, disinterest or boredom---may result from two different, entirely opposite mechanisms. Children are likely to become disinterested if the learning material is either too simple, because the material is either already known or may be picked up and understood quickly; however, they'll also show that same response of disinterest if the material is overly complex, likely because such material is just too overwhelming.

Before dawn today at Cape Canaveral Air Force Station in Florida, SpaceX successfully launched its Falcon 9 rocket carrying a Dragon spacecraft to orbit. The mission makes SpaceX the first commercial space flight firm to attempt to send a spacecraft to the International Space Station. Next, the vehicle will undergo a series of tests to assess whether it is ready to berth with the ISS. From the company announcement:
The vehicle’s first stage performed nominally before separating from the second stage. The second stage successfully delivered the Dragon spacecraft into its intended orbit. This marks the third consecutive successful Falcon 9 launch and the fifth straight launch success for SpaceX.
“We obviously have to go through a number of steps to berth with the Space Station, but everything is looking really good and I think I would count today as a success no matter what happens with the rest of the mission,” [SpaceX founder and chief designer Elon] Musk said.
Here's a worthy petition on the WhiteHouse.Gov site:
Require free access over the Internet to scientific journal articles arising from taxpayer-funded research.
We believe in the power of the Internet to foster innovation, research, and education. Requiring the published results of taxpayer-funded research to be posted on the Internet in human and machine readable form would provide access to patients and caregivers, students and their teachers, researchers, entrepreneurs, and other taxpayers who paid for the research. Expanding access would speed the research process and increase the return on our investment in scientific research.
The highly successful Public Access Policy of the National Institutes of Health proves that this can be done without disrupting the research process, and we urge President Obama to act now to implement open access policies for all federal agencies that fund scientific research.
The rocks, described as a smooth orange colored one and a smaller green one, have been sent to a state lab for testing. Initial tests at the county health department revealed phosphate. Chemistry experts said the rocks may have been coated with phosphorous, a substance that can spontaneously ignite when exposed to oxygen. Meanwhile officials from the U.S. Department of the Navy and from Camp Pendleton say they don't believe the substance stems from any military training exercises. The San Onofre Nuclear Generating Station is believed to not play a role in the source of the burning rocks, experts said on Thursday.

I spent last weekend in the Harvard Forest, participating in hands-on science experiments as part of the Marine Biological Laboratory's science journalism fellowship. The goal was to give us an inside look at what, exactly, scientists actually do. When you're reading a peer-reviewed scientific research paper, where did all that data come from?
Sometimes, it comes from a swamp.
On Saturday, we walked into the Forest's Blackgum Swamp to take core samples out of the muck. There was no standing water in this swamp, at least not when we visited. But I wouldn't call the ground "solid", either. Instead, it was more like a moss-covered sponge. With every step, the ground beneath me would sink and smoosh. In some of the lower patches, that meant a shoe-full of water. In other spots, it was just a disconcerting sensation.
Taking core samples involves a little machine that's like a cross between a shovel and a straw. Made of heavy, solid metal, it has an extendable handle on one end. At the other, there's a hollow, cylindrical chamber that can be opened and closed by turning the handle counterclockwise. You drive the chamber into the ground, turn the handle, and then pull it back out. Once everything is back on the surface, you can open the chamber and see a perfect cylinder of earth, pulled up from below. That cylinder is removed from the chamber, wrapped in plastic wrap, labeled, and put in a long wooden box. Then you do all of that again, in 50 centimeter increments, until you hit stone. We got to about 475 centimeters—15 feet deep. By that point, you'll have collected 1000s of years of layered sediment.
Boing Boing reader Cory Poole is a 33-year-old math and science teacher at University Preparatory School in Redding, CA. He sends in this beautiful video of yesterday's annular solar eclipse, and says:
This is a 60 second time-lapse video made from 700 individual frames through a Coronado Solar Max 60 Double Stacked Hydrogen Alpha Solar Telescope. The pictures were shot in Redding, CA, which was directly in the annular eclipse path. The filter on the telescope allows you to see the chromosphere which is a layer that contains solar prominences. The filter only allows light that is created when hydrogen atoms go from the 2nd excited state to the 1st excited state.
Ken Macleod and the European stem cell research consortium OptiStem have produced a CC-licensed educational comic about genomics called "Hope Beyond Hype." It's available as a free download, or as a &gbp;1 hardcopy, with translations to follow in many languages.
'starts with the true life story of two badly burned boys being treated with stem cell generated skin grafts in 1983. We then follow the successes and setbacks of a group of researchers working together to use stem cells to cure blindness, whilst being introduced to knotty issues that are part of the process, including stem cell regulation and the controversial ethical issues surrounding the subject. Whilst some of the story lines sound like science fiction they are in fact all true, despite the fact the script was written by the well-known Scottish Science Fiction writer, Ken Macleod. Comic book artist Edward Ross illustrated the script with his clear, friendly and attractive artwork, whilst stem cell researchers from OptiStem provided the real-life examples of their research and experiences.'
Macleod is a hell of a science fiction writer, and he's awfully good at comics, too.

“The whole point of this project is to really be able to look these creatures in the eye and get to know them,” he said. The animals are beautiful in their variation, their proximity yielding expressions most humans would interpret in emotional terms — anger, humor, pride.
For instance, I interpret this photo as a frog that has just won the Publisher's Clearinghouse.
Ironically, that's probably not actually an expression of happiness. In the Times article, Sartore says the species is known for its vicious reaction to potential predators.
