Why Life Originated (And Why it Continues)
(PhysOrg.com) -- Today, scientists understand pretty well how life evolves, by mechanisms based on Darwin’s theory of natural selection for survival of the fittest. However, Darwin’s 1859 classic, On the Origin ...

New theory (and old equations) may explain causes of ship-sinking freak waves
On a stormy April day in 1995, the RMS Queen Elizabeth 2 was sailing in the North Atlantic when the ocean liner dipped into a "hole in the sea." Out of the darkness, a towering 95-foot wave threatened to crash ...
