Just slip out the back, Jack: Are humans hardwired to break-up and move on? Posted: 25 Mar 2015 12:17 PM PDT When it comes to romantic relationships, a research review article suggests humans are wired to break-up and move on. Drawing largely upon the field of evolutionary psychology, they say men and women might break up for different reasons. For instance, a man is more likely to end a relationship because a woman has had a sexual relationship with another man. On the other hand, a woman may be more likely to break up if her partner has been emotionally unfaithful.

Two most destructive termite species forming superswarms in South Florida Posted: 25 Mar 2015 12:17 PM PDT Two of the most destructive termite species in the world are swarming together in South Florida. They might mate, forming a hybrid, and that worries the UF/IFAS scientists who found the superswarm.
