Solar-powered sea slug harnesses stolen plant genes - life - 24 November 2008 Video: Watch a sea slug eat algae to nab some of its chloroplasts, and the genes that keep them functioning It's the ultimate form of solar power: eat a plant, become photosynthetic. Now researchers have found how one animal does just that. Elysia chlorotica is a lurid green sea slug, with a gelatinous leaf-shaped body, that lives along the Atlantic seaboard of the US. What sets it apart from most other sea slugs is its ability to run on solar power. Mary Rumpho of the University of Maine, is an expert on E. chlorotica and has now discovered how the sea slug gets this ability: it photosynthesises with genes "stolen" from the algae it eats. She has known for some time that E. chlorotica acquires chloroplasts - the green cellular objects that allow plant cells to convert sunlight into energy - from the algae it eats, and stores them in the cells that line its gut. But a mystery remained. Gene 'theft' Human photosynthesis? It is unlikely humans could become photosynthetic in this way.

The Biology Corner MIT Technology Review Six Amazing Websites that Make Your Writing Stronger Long writing activities are not very frequently done in class. I tend to think that my students are like me; I need the right kind of atmosphere. Writing requires time, silence and lots of inspiration. Ideally, at this time of the year, I would probably wish to be sitting next to a fireplace with the most perfect instagrammable snow falling outside my window while drinking a nice cup of coffee waiting for inspiration to strike. Unfortunately, there isn’t any snow where I live so I’ll have to make do with a bit of rain and some reddish trees. Inspiration, the most important word when writing and something my students claim to lack. These are some great sites that can help you make your writing stronger. Photo by Tekke 1.

Bill Nye | Official Website for Bill Nye The Science Guy (equiv. de c'est pas sorcier) Summarize Articles, Editorials and Essays Automatically Man rescued after being lost in IKEA for 12 days – Luxembourg Wurst ARLON, Belgium — A disoriented shopper was rescued on Thursday after being lost for nearly two weeks in an IKEA store near the Luxembourg border. Late last month, Michael Parrish, 33, entered the premises for a “quick stop” to purchase an inexpensive lamp for his infant son’s bedroom and 100 lime-green napkins requested by his wife, he says. However, after more than an hour of unsuccessfully searching for the cash registers, he knew he was in trouble. “I kept following those stupid arrows on the ground, but as if by design, they only led me in circles,” he told the Wurst. “They just kept repeating in these comical Belgian accents, ‘Euh, no, I am so sorry, we have no more in stock,’” he said. Parrish says that although he was able to sustain himself with Lingonberry soda and frozen Swedish meatballs that he would sit on to warm, he still feared he would never again see his wife and child. “Unfortunately, Mr.
