Feminine leadership traits: Nice but expendable frills?

A new study exploring the tradeoff between masculine and feminine leadership traits reveals that women internalize a stereotypically masculine view of leadership. The research, published in Frontiers in Psychology, suggests that women may feel disadvantaged compared to male leaders if they adopt traditionally feminine styles.

Study reveals best use of wildflowers to benefit crops on farms

A Cornell University study found that wildflower strips on farms boost strawberry yields when surrounded by the right mix of natural habitat and agricultural land. The optimal range for pollinator attraction is between 25 to 55 percent surrounding natural landscapes, where wildflowers also draw more beneficial insects.
