    Here’s one aerodynamics research finding no supermodel should miss: Long, luscious eyelashes can, in fact, get too long.There’s a sweet spot in the range of lash lengths —about one-third the width of the eye —reports David Hu of Georgia Tech in Atlanta.

    Noise made by humans can be bad news for animals

    I keep looking over my shoulder at the dark wall of roadside trees that passing headlights make slightly less black.
