Could humans build a tall tower or giant rope to space?
The movie Ad Astra shows a space antenna, a spindly structure reaching up into the stars. We look at what it would take to build something that big.

‘Biodegradable’ plastic bags often don’t break down
Biodegradable plastic bags are supposed to break down more quickly than ordinary plastics. But that may not happen, a study finds.

Dry sand can bubble like the blobs in a lava lamp
Put two types of sand grains together in a chamber and they can flow like fluids. All it takes is a jiggle and some gas.
