    Aliens may be trying to communicate with Earth by flashing blinking lasers towards our planet like a cosmic lighthouse, astronomers believe.Laser scientists at the Vienna University of Technology are searching for faint but repetitive light signals from the distant reaches of space, in the hope of identifying signals sent out by extraterrestrials, according to Astrobiology Magazine. Because of their ability to transmit signals over vast distances, lasers have long been considered a possible means of contact by alien species. But while astronomers have searched tens of thousands of stars for laser signals in the past – without identifying any...

    Blinking Causes Brain To Go Off-Line 03 Jan 2013 New research from Japan suggests that blinking does more than stop our eyes drying out: it is an active process that causes the brain to go off-line, into a more reflective mode, before giving renewed attention. Tamami Nakano of Osaka University and colleagues write about their findings in the 24 December online issue of the Proceedings of the National Academies of Science, PNAS. In earlier work, where they had invited volunteers to watch Mr Bean videos, Nakano and colleagues discovered that people's eyes blink when they need to pay less attention,...

    During last night's debate did anyone else notice 0bamugabe was communicating with someone off stage (his handlers/ Axelrod, Mooch etc.) by very deliberately blinking once (for Yes?) or twice (for No?)? Most video segments of OBozo waiting to rebut Romney seem to have some evidence of this, I know it was not just imagined. What theories do you have on the types of questions he was answering? (This could be fun!)
  • New nanocrystals show potential for cheap lasers, new lighting (crystals continuously emit light!)

    For more than a decade, scientists have been frustrated in their attempts to create continuously emitting light sources from individual molecules because of an optical quirk called "blinking," but now scientists at the University of Rochester have uncovered the basic physics behind the phenomenon, and along with researchers at the Eastman Kodak Company, created a nanocrystal that constantly emits light. The findings, detailed online in today's issue of Nature, may open the door to dramatically less expensive and more versatile lasers, brighter LED lighting, and biological markers that track how a drug interact with a cell at a level never...

    Annoyed Reader
    The purpose of FreeRepublic.com's multiple message boards is to limit the topics for each board to particular topics. Posting the same message on all the boards defeats the purpose of multiple-boards for special topics. It is very annoying to see the same message on every bulletin board. PLEASE! DO THE READERS A FAVOR. STOP CROSS-POSTING YOUR MESSAGES!
