    A follow-up study of dog-personality tests suggests that they don't have the predictive power many puppy purchasers expect.

    In mustachioed rodents called tuco-tucos, group life seems to have fostered more diverse immune systems than has solitary living.

  8. Fig-Wasp Upset: Classic partnership isn’t so tidy after all

    Genetic analysis suggests that a textbook example of a tight buddy system in nature—fig species that supposedly each have their own pollinating wasp species—may need to be rewritten.

  9. Animals

    The first analysis of what the mouths of begging birds look like in the ultraviolet spectrum reveals a dramatic display that birds can see but people can't.

  10. Animals

    A test of what once seemed too obvious to test—whether ant colonies suffer after being raided by slavemaker ants—suggests that some of the raiding insects have been getting unfair press.

  11. Animals

    Bluegill sunfish have provided an unusually tidy test of the much-discussed prediction that animal dads' diligence in child care depends on how certain they are that the offspring really are their own.
