For more than three centuries scientists have believed that human sperm swim by swishing their tails in a side-to-side, symmetrical motion. But that’s because we’ve been looking at them with 2D microscopes.

Using state-of-the-art 3D microscopy, a piezoelectric device, and mathematics, researchers in Mexico discovered how sperm really move: They spin, with a wonky asymmetrical wiggle. The researchers reported their discovery today in the journal Science Advances.

I thought the science was settled.

Swim?  I bet mine can't even tread water anymore.

When told my wife about this revelation she said, "So they screw?"

Love of my life.
