Flipping hot Jupiters: Why some planets orbit the wrong way
(PhysOrg.com) -- In the last few years astronomers have observed that in some extrasolar systems the star is spinning one way and the planet, a "hot Jupiter," is orbiting the star in the opposite direction. ...

Improving crisis prediction, disaster control and damage reduction
Some disasters and crises are related to each other by more than just the common negative social value we assign to them. For example, earthquakes, homicide surges, magnetic storms, and the U.S. economic recession are all ...
