Your Head Might Be On Sideways Your Head Might Be On Sideways
3 weeks ago En
In your brain the right side controls the left half of your body and vice versa. We still aren't sure why this is, but some scientists have come up with a pretty bizarre explanation: that some ancient vertebrate ancestor was born with its brain on backwards.

Why Can't You Compost Meat? Why Can't You Compost Meat?

Composting becomes more widespread and accessible all the time, keeping millions of tons of food waste from ending up in landfills every year. But there is one quirk of some composting programs that can be a little annoying: they don't accept meat scraps. But why? And are there ways to overcome this limitation?

Thank you to the Monterey Bay Aquarium for partnering with us on this episode of SciShow. Visit https://www.montereybayaquarium.org or if you are in the area, swing on by to learn more about the beauty and wonder of the ocean. There are incredible creatures living in the ocean that have the power to reshape the planet’s atmosphere - and you’ve probably never even seen them before. These microscopic critters are called phytoplankton, and almost all life, both on land and in the ocean, depends on them. Hosted by: Hank Green SciShow has a spinoff podcast!
