One of the great joys of camping out in a national park is chowing down by the fire. But campers aren't the only ones drawn to burgers and s'mores roasting over an open flame, beneath a mass of twinkling stars.
Those rich aromas can also prove irresistible to the local critters. From bears to foxes to coyotes, biologists have documented wildlife getting irrevocably hooked on our food and food waste. And for good reason: Our food is way more calorie-rich — and thus, better for making babies — than the standard black bear fare of insects and leaves.
Summer living is supposed to be easy — school is out, the days are long, the traffic eases. But it's not all inner tubes and lemonade: Summer can throw us some curveballs, too. How can I avoid sunburn? What can I do to stave off that brain freeze? Why do my s'mores always burn?
Fear not; NPR is here to help. As part of our new Summer Science series, we'll turn to science to tackle these vexing questions, starting with how to build the perfect campfire.
