Next time you're stung by a wasp or a honeybee, consider the elegantly designed stinger that caused you so much pain. Researchers found that the stingers of the two species are about five times softer at the tip than at the base to make it easier to pierce skin. The stingers are harder closer to the insect's body so they don't bend too much, or break, as you yelp in agony.
