Welcome to Science Friday! This week, explore mars with the sand trapped Spirit rover, see Cpt. Piccard fly a solar plane, own your very own robot scientist, and send a message to whales in space. All this an more plus our gadget of the week: the collapsible lampshade that’s made with lasers!
Sand Trapped Spirit Rover Makes Big Discovery
As you may know, the MER Rover Spirit got stuck recently while roving around a small crater on the dusty red planet. Well it turns out, just as previous follies have led to cool discoveries before, that the act of Spirit trying to free herself has turned up something interesting in the Martian soil. “Spirit had to get stuck to make its next discovery,” says Arvidson. As the rover tried to break free, its wheels began to churn up the soil, uncovering sulfates underneath. “Sulfates are minerals just beneath the surface that shout to us that they were formed in steam vents, since steam has sulfur in it. Steam is associated with hydrothermal activity – evidence of water-charged explosive volcanism. Such areas could have once supported life.” Great news from the sand trapped rover who is still trying to break free.

Captain Piccard Flies a Solar-Powered Plane
A Swiss adventurer named Bertrand Piccard has successfully launched and landed an experimental solar-powered plane. According to Piccard, the low altitude journey proved the prototype Solar Impulse was capable of safely flying – even though it traveled only 350 meters. Although Piccard conceded that the maiden voyage of the Solar Impulse may appear to be little more than a “flea hop,” he insisted that it represented a totally “new and uncharted” way of flying. “Never before – in the whole history of aviation – has an aircraft so big, so light and consuming so little energy actually flown."

Download Your Own Robot Scientist!
Ever wanted to have a robot to do your research for you? If you are a scientist, you have almost certainly had this dream. Now it’s a real option: Eureqa, a program that distills scientific laws from raw data, is freely available to researchers. The program was unveiled in April, when it used readouts of a double-pendulum to infer Newton’s second law of motion and the law of conservation of momentum. It could be an invaluable tool for revealing other, more complicated laws that have eluded humans. And scientists have been clamoring to get their hands on it. “In most of science, you try to keep everything constant except for one variable. You turn one knob at a time, and see how the system responds. That’s wonderful for linear systems,” said a Eureqa user. “But most biology is complex and non-linear. Emergent behaviors are very hard to understand unless you turn many knobs at a time, and we can’t figure out which knobs to turn. So we’re going to let Eureqa pick them.”

Are Blue Whales Trying to Summon Their ET Brethren?
They may not be humpbacks, but Blue Whales have been singing a different tune lately, specifically their songs have changed to deeper tones, and scientists don’t know why. Mark McDonald, president of Whale Acoustics, a company that specializes in the sonic monitoring of cetaceans, noticed the change beginning 8 years ago. Their detectors are triggered by songs that match a particular waveform. Every year, McDonald had to set them lower. Scientists do not have any answers at this point, only lots of recordings and lots of questions. Of course, it seems obvious if you’re well versed in your history of the future. They are just communicating with the giant starship-destroying, rod-shaped probe floating in space near the whale home world! Any vulcan could tell you that!
Because EVERYTHING makes more sense when compared to dinosaurs!
Gadget of the Week: Collapsible Lamp Shade — Built With Lasers!
Thanks to smart geometry and engineering comes this collapsible lampshade, going from flat latticework to squared-off cube in an instant. Place it over a lighting fixture and you have a soothing, glowing shape that doesn’t seem to be from this world. Even more impressive than the final product is the way this unusual lampshade was created:
“The process works by sweeping a laser across a pan of powdered nylon; when the lasers hit the nylon, it fuses (“sinters”). The process repeats in layers, until the final product emerges. Thus, you can create interlocking shapes all at once–for example, a chain whose links are completely closed.”
Take a look at this video and you’ll see how it unfurls:
If you are on Twitter, you know there are plenty of amazing people out there tweeting away. And, many of them are scientists! Every Friday I’ll be bringing you a new list of great scientists and techies to follow on Twitter. This week…
- @CERN: CERN, the European Organization for Nuclear Research, is the biggest particle physics laboratory in the world.
- @Oatmeal: The oatmeal is full to the brim with comics, quizzes, and stories
- @ActuallyNPH: Niel Patrick Harris. I act some. Dig variety acts, Pixar, puppets, theme parks and great meals.
Not enough science for you? Here’s a warp-speed look at some more science tid-bits that are worth a look.
