Growing Food with Seawater

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.

Using Neuroscience to Talk to People in a Vegetative State

A scientist figures out how to talk to the brain when the body won't respond.

Watch Now

People who suffer extreme brain trauma sometimes fall into what is known as a "persistent vegetative state." Unlike a coma, where the patient is completely immobile and unconscious, people in a vegetative state will sleep, wake, and open their eyes — without showing any sign of awareness or consciousness. They don't speak, move on their own, or respond to questions. Also unlike a coma, which is rarely longer than a…

Can Sleep Deprivation Cure Depression?

Losing sleep can have a lot of adverse health effects, but recent science shows it could also have a surprising…

Watch Now

Studies show that loss of sleep can lead to memory loss, compromised immunity, weight gain, and mood swings. However, scientists are now finding that sleep deprivation may be used to treat depression. Losing sleep has the opposite effect on those struggling with depression. It restores the circadian rhythm that is usually flat in depressed people and it helps balance the parts of the brain that regulate mood. Unfortunately, the positive…
