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.

On Wednesday, rapper Albert Johnson—better known by his stage name Prodigy—passed away at the age of 42 from complications of sickle cell disease, an inherited blood disorder he'd had since birth.

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".
