Comments Off on Spaceships With Solar-Powered Lasers Could Deflect World-Ending Asteroids

Solar technology has taken off and literally shot into orbit over the last few years with satellites and the USAF’s top-secret shuttle being powered by photovoltaic panels. Now a team from Scotland’s University of Strathclyde believes that the renewable energy source could have planet-saving potential – they’ve proposed building a series of spacecrafts equipped with solar-powered lasers that could deflect incoming asteroids.

Japanese Tsunami Dock Hits Oregon Beach With Army of Alien Species Attached!

Comments Off on Japanese Tsunami Dock Hits Oregon Beach With Army of Alien Species Attached!

An enormous Japanese dock that was cast out to sea by the tsunami last year has landed on an Oregon beach. While it is not the first piece of debris to reach the US , it has bought with it a veritable menagerie of ‘alien species’ that environmentalist fear could have a devastating impact on local ecosystems. The 66-foot dock dock originated from the Japanese fishing port of Misawa and during its year-long, 5,000 mile journey has picked up a host of sea creatures including Asian crabs, sea stars, algae, urchins, barnacles, snails, and other life-forms. In fact, there are so many creatures on it that the  Oregon Department of Fish and Wildlife estimates they weigh over 100 tons! The Japanese dock has been likened to an “alien mother ship” full of invasive species that could pose a threat to the native wildlife of Oregon’s Agate Beach . To stop any long-lasting damage, volunteers from the Oregon Department of Fish and Wildlife have been using shovels, rakes and even fire to scrape the dock clean. Speaking to National Geographic , invasive species biologist  John Chapman  said: “We were caught flat-footed. This was a close-encounter-of-the-fourth-kind type of event, where an alien mother ship from outer space lands on our shores.” “Sixty percent of the dock’s surface area was on the bottom when it washed up on the beach, and the [organisms] that were on there were scraped off and washed away,” Chapman said. “It’s like a spectacular, large, dirty needle that just got stuck into our ecological arm, into our ecosystem.” While it is impossible to completely predict the impact the new species will have, Chapman believes they could out-compete native oysters and crabs and devastate the local economy. “On that dock probably 50 or more species that survived the crossing are not species that we’ve seen crossing the globe before,” Chapman said. “And we’ve also already identified three real bad characters that were aboard.” The alien species include wakame seaweed and the  Japanese shore crab , which has already invaded the US East Coast and decimated native shellfish populations. The dock is expected to be towed to Newport once it has been treated, where it will then be scraped. So far, it is estimated that some five million tons of debris were washed off Japan’s coast , and NASA is currently tracking 1.5 million tons of it. + Oregon Department of Fish and Wildlife Via National Geographic Images: Oregon Department of Fish and Wildlife Permalink | Add to del.icio.us | digg Post tags: agate beach , alien species , asian shore crab , ecosystems , Fukushima , japanese tsunami , National Geographic , tsunami , tsunami dock

Comments Off on Scientists to Use Firefly Bioluminescence to Create Energy-Free Lighting

A team of scientists from Syracuse University are using nanotechnology to harness the natural bioluminescence of fireflies in order to create lighting that doesn’t need any energy to glow! By using nanotechnology , the team believe that they can create a natural bioluminescent lighting system that is 20 to 30 times more efficient than any previously made.
