Conservative CEOs are four times more likely than their liberal counterparts to acquire international firms rather than forge new alliances when entering foreign markets, according to new research. The same study finds that these political biases can be moderated by active, independent boards.

Magnetic energy strings flex, wiggle and reconnect in a nanomagnetic array

A multi-institutional team exploring the physics of collective behavior has developed and measured a model nanomagnetic array in which the behavior can be best understood as that of a set of wiggling strings. The strings, which are composed of connected points of high energy among the lattice, can stretch and shrink, but also reconnect. What makes these strings special is that they are limited to...
