There are two broad categories of behavior that, in humans, may be labeled as "war." The first and most familiar to us are large-scale battles between two or more opposing forces. Similar behavior is seen in many species of ants and other social insects, in which battles may take place between tens of thousands of individuals from different colonies. Most of these battles take place over territory. Insects deploy a wide variety of tactics in these battles -- including, in at least one termite species, suicide bombing! As they age, workers in the species Neocapritermes taracua fill up with toxic blue crystals. In battle, the termites explode, spraying their enemies with poison.
The age-old battle between cat lovers and dog lovers over which creature is preferable as a house pet just got a little more interesting. A new book by a prominent feline researcher who has been studying cats for over 30 years reveals what many of us have suspected about the true nature of cats: that they view us humans as oversized, lazy mama cats and, perhaps not surprisingly, generally view humans as something other than companions.
A wily parasite well known for influencing the behavior of its animal hosts appears to play a troubling role in humans, increasing the risk of suicide among women who are infected, new research shows.
