We all know what an egg looks like, right? Well, we might know less than we think—bird eggs can be spheres, teardrops, oblong, and anything in between. An interdisciplinary group of scientists may have made progress in cracking the mystery behind how these different shapes emerged.
Ticks are horrifying, plain and simple. Even if they weren't vectors for nasty infections, the fact that they swell up like tiny blood balloons and then burst if you don't remove them properly is enough to make you never want to set foot in the woods again. And guess what: they can also make you allergic to hot dogs and hamburgers, which is pretty darn unpatriotic for a tick named Amblyomma americanum.
Americans are spending $200 billion a year to treat their back pain, and most aren't even happy with the treatment they're getting. They're often stuck relying on addictive pain meds or spending a fortune on physical therapy.
"Are you allergic to any medications?" I've answered that query dozens of times since a childhood incident when penicillin, taken to treat a minor infection, instead gave me an itchy rash all over my body.

When we die, our bodies become the grass, and the antelope eat the grass. And so we are all connected in the great Circle of Life. Everyone knows that classic line from Disney's "The Lion King". Kids and parents might have been slightly less charmed by this variation: The wildebeest must cross the river to eat, and a whole bunch of them die in the process. And then everything in the river gets to feast on their rotting remains.
Talk radio can be scary for humans, but for mountain lions, it's enough to put them off their dinner.
