If you've just been bitten by a venomous snake and your flesh is starting to rot and you can't breathe, you may not be in the mood to hear how beautiful snake venom can be. But from a safe distance, it really is a marvel to behold.
Snake venom is a blend of molecules, many of which are exquisitely adapted for wreaking havoc. Some are enzymes that slice muscles apart. Some grab onto proteins that normally form clots, so that a snake's victim can't stop bleeding. Many snake venoms attack the nervous system with molecular precision that's so good that neuroscientists have snakes to thank for some of their biggest discoveries.
