Words really cannot express what is happening in Japan at the moment, I think I will leave it to others better suited and more capable of expressing what is happening there. I have been to Japan once, for two days, and even in that short time it struck me as a more beautiful and welcoming place than modern pop culture gives it credit for. My hopes go out to everyone there and everyone who has loved ones there.
Two great sources of info on the unfolding Nuclear issue in Japan are Brain Dunning's twitter feed (oh an Skeptoid.com of course!) and Racheal Maddow's great easy to follow updates on her show.
