MIT student engineers won a competition to transform SpaceX and Tesla Motors co-founder Elon Musk's idea into a design for a Hyperloop to move pods of people at high speed.
Promiscuity could reduce benefits of successful mating, research shows.
Male fruit flies could find their chances of fathering offspring radically reduced if they are last in the queue to mate with promiscuous females before winter arrives, according to new University of Liverpool research.
This election year has produced 17 Republican presidential candidates, which on its surface may appear to give the party a competitive advantage. Evolution, however, disagrees.
