Genes inherited from mothers (matrigenes) and fathers (patrigenes) usually work harmoniously in the offspring. However, kin selection theory predicts these genes may be in conflict in interactions among relatives in which they are unequally represented (half-siblings). In honey bees, patrigenes are predicted to favor daughters that lay eggs themselves rather than remaining sterile and rearing their half-sisters’ offspring. An experimental test bears out this prediction.

Curious seismologists who looked at the recordings made by a seismic station four miles away from the “cook-off” of an ammunition holding area in Iraq in 2006 found they could distinguish, mortars, rockets, improvised explosive devices, helicopters and drones. Seismology is increasingly being used for investigative purposes, they said, not just to detect earthquakes.
