  • Energy Scavenging: Squeezing Watts from Motion

    Using the same technology that allows hybrid cars to recycle braking energy, Max Donelan invented a gadget that produces power from the human knee - capable of producing 2.5 watts of electricity per leg. The unit is not too practical at the moment, but the technology and potential is sound. Currently the knee power generator weighs in at 3.5 lbs and it looks very awkward to have strapped on. Although 2.5 watts doesn’t seem like too much it is enough to power 5 mobile phones free of charge or resource. >> Read the Full Article

  • Whales, lizards inspire hi-tech bio-mimicry

    Whale hearts hold clues to making pacemakers and lizard skins are showing how to cut friction in electrical appliances as companies mimic nature to develop high-tech goods, a U.N.-backed report said on Wednesday. Among other advances that could save hundreds of millions of dollars, the wings of desert beetles could improve water collection and the drought-resistant African "resurrection plant" indicates ways to store vaccines without refrigeration. >> Read the Full Article

  • Remote controlled planes to explore hurricanes

    MIAMI (Reuters) - U.S. researchers are ramping up their use of unmanned, remote-controlled airplanes this year to penetrate the heart of Atlantic hurricanes in the hope of learning more about what makes the giant storms tick.

  • In Vitro Meat, a More Humane Treat

    The ongoing world food crisis has incited riots and protests in more than ten countries over the past several months. In Haiti, seven people were killed in riots that led to the ouster of Prime Minister Jacques Edouard Alexis. Egypt's President Mubarak enlisted the army to produce and distribute bread after several people were killed in bakery clashes. Drought, a declining dollar, and a shift of investment money into commodities have all contributed to bare shelves and empty bellies. >> Read the Full Article

  • Scientists announce top 10 new species, issue SOS

    The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists – scientists responsible for species exploration and classification – today announce the top 10 new species described in 2007. On the list are an ornate sleeper ray, with a name that sucks: Electrolux; a 75-million-year-old giant duck-billed dinosaur; a shocking pink millipede; a rare, off-the-shelf frog; one of the most venomous snakes in the world; a fruit bat; a mushroom; a jellyfish named after its victim; a life-imitates-art “Dim” rhinoceros beetle; and the “Michelin Man” plant. >> Read the Full Article

  • Spain's drought a glimpse of our future?

    Barcelona is a dry city. It is dry in a way that two days of showers can do nothing to alleviate. The Catalan capital's weather can change from one day to the next, but its climate, like that of the whole Mediterranean region, is inexorably warming up and drying out. And in the process this most modern of cities is living through a crisis that offers a disturbing glimpse of metropolitan futures everywhere. >> Read the Full Article

  • Study Cites High Cost of Global Warming, Says Action Would Be Cheaper

    Doing nothing about global warming would cost America dearly for the rest of this century because of stronger hurricanes, higher energy and water costs, and rising seas that would swamp coastal communities, says a new study by economists at Tufts University. The study concludes that it would be cheaper to take aggressive action to cut greenhouse gas emissions than it would be to suffer the consequences of a changing world. "The longer we wait, the more painful and expensive the consequences will be," the report states. >> Read the Full Article

  • Race for Antarctic krill a test for green management

    In the global rush for resources, a tiny pink crustacean living in the seas around Antarctica is testing man's ability to manage one of the world's last great fisheries without damaging the environment. Krill, which grow to about 6 cm (2 inches), occur in vast schools and is the major source of food for whales, seals, penguins and sea birds. Without it, scientists say, the ecosystem in and around Antarctica could collapse. >> Read the Full Article
