Special Molecule Gives Birds a Magnetic Biocompass

Aaron Rowe writes "CORDIS news reports that a team of scientists has identified a family of molecules called cryptochromes that allow migratory birds to sense magnetic fields. Curiously enough, these molecules only function when accompanied by blue light. The article also mentions, 'The researchers also suggest that, as cryptochromes have been strongly conserved throughout evolution, all biological organisms could have the ability to detect magnetic fields, even if they do not use them.'"

    Where do I sign up to get these powers enabled? I totally would go for it, even if it is a really lame 6th or 7th sense. Like, if I was lost in the woods with no cell phone and nothing to make a shadow with, and no running water... it could be mildly useful!

      You may be able to hack the setting w/o a reboot,
      but be sure to backup your data first.
