App allows citizen scientists to track monarch butterfly migration
If you've ever pulled out your phone to take a picture of a butterfly, researchers want your help. A team from the University of Maine is using an app that lets citizens scientists along the East Coast take photos of monarch butterfly migration sites and log details about where they're found. The responses will be compiled in an online database and help researchers determine if their monarch migration predictions are accurate.
Insects could be extinct within a century, scientists say
Insects are dying so rapidly, they could disappear within 100 years, according to the first global scientific review on their decline. A third of species are endangered and more than 40 percent face the threat of extinction in the next few decades, according to the study, which was published in the Biological Conservation journal.
GE turns butterfly-inspired tech into cheap, accurate thermal sensors (video)
When last we heard from GE and its Morpho-butterfly inspired sensors, all the talk was about detecting chemicals. And, with $6.3 million in funding coming from DARPA, we're not surprised. In the latest issue of Nature Photonics, however, the company's researchers show that the wing-like structures are just as good at detecting heat as they are ricin attacks. By coating them with carbon nanotubes the team was able to create a sensor sensitive to temperature changes as small as 0.02 degrees Celsius with a response rate of 1/40 of a second. The sensors could eventually find their way into imaging devices and medical equipment, and are expected to cost just a fraction of similar technologies currently on the market. Of course, since DARPA is still involved with the project, there are some potential security uses as well -- such as screening devices and fire detection.

Inhabitat's Week in Green: hydrogen-powered space plane, Japan's solar surge and urban farms of Ze Future
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Green transportation took off for the stars this week as Inhabitat reported that the European Space Agency has approved of a new hydrogen-powered "Skylon" space plane, and we spotted a hot Star Wars-inspired electric chopper that wouldn't look out of place on the Death Star. We also learned that NASA plans to rejoin the space race with a new MPCV craft fit for deep space flights, while here on Earth we saw GE harness the power of the sun to charge Volt EVs before they hit dealerships. Speaking of solar power, Japan unveiled plans to construct 10 new solar power plants in the wake of the Fukushima Nuclear Crisis, while Switzerland announced that it will completely phase out the use of nuclear power. We also showcased a stunning chandelier made from 500 fluttering photovoltaic butterflies, and we saw Nevada kick-start construction on the US' first molten salt solar plant, which will generate energy long after the sun has set. We also brought you several incredible feats of architecture this week, from a restaurant made from a recycled Soviet airplane in Zurich to an innovative cocoon-like building made from sugarcane that recently won an AIA competition. We also showed how Plantlab is making vertical urban farms a reality, and we spotted a sky-high proposal for an energy-generating city on stilts that would hover over Manhattan. Finally, this week we rounded up some of our favorite eco apps and services that can help you green your consumption.
Solar-powered butterfly chandelier is a fluttering mass of art and light
Look closely at that blue blob up above and you'll realize it's made up of 500 butterflies, each one meticulously cut from photovoltaic cells. The hundreds of insects collect the sun's rays as they flutter around a giant glass bulb that turns into a churning mass of light after dusk. The Virtue of Blue chandelier is a stunning work of art by Dutch designer Jeroen Verhoeven that draws connections between the beauty and power of nature and the importance of sustainable energy... or, you know, just something trippy to stare at while you sip a few cocktails at the Blain|Southern gallery in London. %Gallery-124262%
GE lands $6.3 million DARPA grant to develop 'bio-inspired' sensors
Do butterflies hold the key to the next generation of chemical sensors? DARPA apparently thinks they might, and it's just awarded GE a $6.3 million grant to further develop a project that the company's research division began three years ago. That project was sparked by the discovery that the nanostructures from the wing scales of butterflies have acute chemical sensing properties, which GE has since been working to replicate in a sensing platform that could instantly detect a wide variety of chemical threats. What's more, GE says that it's sensors could eventually be made in "very small sizes, with low production costs," which would let them be used for everything from emissions monitoring at power plants to food and beverage safety monitoring at home. Full press release is after the break.
Puzzlotto brings a different kind of game (and a cash prize) to the App Store
Puzzllotto has been about as hidden as the lemurs you can see in the screenshot over there, for some reason -- the concept isn't real easy to grasp, and if you just stumbled across the "game" in the App Store, odds are that you'd think you had $5 stolen from you. But there is a weird story hidden here, both literally and figuratively. David Lanham and Mike Lee contributed to the Puzzllotto, which features unusual game play -- there's just a picture of a forest, and a few eyes that you can touch to make lemurs and other creatures pop out. I would tell you more, but I haven't actually figured it out yet -- there's a "fosa" that will scare away any lemurs or butterflies you've summoned, and I know that the butterflies are basically a progress meter, but other than that I have no idea.But Puzzllotto isn't just that perplexing app -- it's been dubbed "fundware" by Lee, and 10% of the proceeds from the game will go to the Madagascar Fauna Group to support the habitats of lemurs, fosas, and butterflies. And it's actually a puzzle to be solved, with a cash prize -- if you can be the first to figure out the "puzzle" behind Puzzllotto, United Lemur will give you a cash prize out of their prize pool, currently at $5000, and growing every day for 31 days. If no one claims the prize at the end of the 30 days, all the money will go to charity, project over. You can follow updates on their Twitter -- it sounds like no one's claimed any prizes yet, which is no surprise -- if there are any clues in the app, they're very, very hard to find. United Lemur claims that there is a game in there (and that it is worth the $5 entry fee), but so far, all players have found is a few screens of the weird lemur puzzle.But it is a different kind of game -- a cash prize handed out by a flabbergastingly tough puzzle disguised as an App Store game, all designed to benefit a charity. Lee says on his blog that they wanted to make a game where players couldn't cheat by telling each other the answer, but maybe they didn't realize that part of the fun of Myst is sharing the strategy with other players. And if you don't want to shell out the $5 on Lee's word, it might be fun to just wait until the solution gets posted somewhere anyway. Have you solved any part of Puzzllotto yet?
