The Bulletin of Atomic Scientists may have found a new way to track secret nuclear tests from those rogue nations (cough cough North Korea cough cough) who are trying to keep those tests under wraps.

Researchers from around the globe using data captured by a camera on a Hawaiian mountaintop, have photographically captured the dim red atmospheric glow caused by the March 11 tsunami issued by the Japan earthquake that devastated that country and traveled across the Pacific to do millions of dollars worth of damage elsewhere. The observation--the first of its kind--could be used to predict future tsunamis before they hit, saving countless lives.
Sometimes you're just at the right place at the right time. Astronauts aboard the ISS experienced just such a moment when they captured this captivating image of a rare aurora australis over the Southern Indian Ocean likely caused by a coronal mass ejection from the sun late last month.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
