Building with moon rocks

By Sid Perkins / May 22, 2013

Sergio Parra, a 17-year-old engineer from Hoschton, Ga., analyzed concrete made from materials likely available on the moon. His findings suggest that construction on the moon might be more economical than previously thought. Credit: Patrick Thornton, SSP

Working on the moon with lunar soil and grit could prove easier, more efficient and less costly than using earthly materials

Walking on water

By Stephen Ornes / July 30, 2012

his cornstarch and water goo looks like a liquid, but put your hand on the surface and pull up, like a researcher here, and the goo sticks and rises with your hand (before gravity takes over and it drops). That's because in motion, this goo becomes thick and heavy like a solid. Credit: University of Chicago

Sea changes

By Stephen Ornes / April 7, 2011

Blue patches indicate parts of the ocean that are more acidic than the yellow and red areas. Stars show coral reefs, which can lose their skeletons in more acidic water.

Carbon dioxide is making the oceans more acidic
