Spinoff 2012 released

A plant texts a farmer to say it needs more water; an invisible coating scrubs pollutants from the air; a robot roams a hospital's halls, aiding doctors and nurses by recording vital signs and registrations. The 2012 edition of NASA's annual Spinoff publication captures a nation and world made better by advancements originally achieved for space technology. Stennis Space Center, Miss., played a key role in developing the self-cleaning coatings. (Source: PRNewswire, 02/13/13) Spinoff available online here.
