They also have developed aeroponics which can help feed people.

Soil. Water. Say that plants don't need them and people may think you've traded your cow -- and your good sense -- for a handful of beans. But NASA-sponsored plant experiments prove that you don't need soil and lots of water to grow a beanstalk that would make Jack proud."

These experiments use the principles of aeroponics: growing plants in an air/mist environment with no soil and very little water.

That sounds so cool!:yes:

Its pretty cool alright.

Did you see this?

Trillion-frame-per-second video
By using optical equipment in a totally unexpected way, MIT researchers have created an imaging system that makes light look slow.

It might allow them to study light in different ways.
