If your health insurer pays too much for a claim, you might think that would be a good kind of problem. But it could turn out to be more of a headache than a windfall.

Pulling out a porcupine quill is painful and slow, as many a dog discovers to its dismay after tangling with the big rodent. But those tenacious quills are inspiring efforts to develop better medical devices, including less painful needles.
