Energy from the air?  How very Tesla of you!   But unlike America's favorite quirky inventor, this isn't transmitted power and no dogs have to die.    It's using moisture from the air - and the more humidity you have the better.

Similar to the way solar cells capture sunlight, hygroelectric collectors would collect moisture and use it to light a house or recharge an electric car.   Bonus: Panels on the rooftops of buildings could prevent lightning strikes - and the technology is already in the early stages of development.
Are you a brilliant student but can't take tests well?   A star athlete in practice but nerves overwhelm you at game time?   It's common but in varying degrees; the line between someone who worries about performance and therefore does even better and someone who 'chokes' under pressure is fuzzy.

A new anthropology study challenges a half-century of conventional wisdom that Neanderthals were primitive `cavemen' overrun and out-competed by modern humans arriving in Europe from Africa.
