Water is in short supply in much of the world — but what if we use seawater? It’s been a dream for years, but now technology is making it possible. This new seawater greenhouse uses a clever cardboard design to distill fresh water from salt water cheaply and efficiently.

It’s helping grow crops in Somaliland, and could help stop the water crisis in Africa and other parts of the world that are susceptible to drought. The founder of Seawater Greenhouse, Charlie Paton, explains how unlike traditional greenhouses — which are hothouses — this one is a “cool house” that is ideal for growing temperate crops in deserts or other hot, arid regions.

At XCOR, the dream of taking regular commercial flights to space is alive and well.
Watch Now

At its peak, NASA’s shuttle flew to space a few times a year. XCOR wants to be something more like Southwest Airlines for space. They're working on a spacecraft prototype with a very ambitious goal: four daily flights to space, five days a week. If XCOR is successful, they could take more people to space in six months than NASA did in 30 years.

Vanna started to notice a change in her vision. Six months later, she was legally blind. But Vanna never lost hope, and enrolled in an experimental clinical trial. Her doctors injected stem cells from her hip into her optic nerve. Afterwards, she started to regain her vision. Amazingly, Vanna can now see. This is the story of reversing blindness.
