The mysterious "star dune" in the Sahara desert is on the move.
@popsci reports: "Morocco's Lala Lallia — one of the world's oldest known 'star dunes' — is slowly inching west."

Countries on the edge of the Sahara desert are reversing desertification by just digging half circles.
The ground in these places is too compact for water to soak in during wet season which leads to flooding but digging these holes gives the water a place to stop and soak in. And they’re pushing back the desert with this. By just digging holes.
