December 3, 2013 The space agency has announced plans to grow turnips, basil and cress on the moon by 2015. The experiment could be good news for astronauts sick of their freeze-dried fare. But researchers say the real goal is to see if humans could one day live — and farm — on the moon.
December 3, 2013 A cookie in the oven almost looks like a monster coming alive. It bulges out, triples in size and then stiffens into a crisp biscuit.

November 26, 2013 A fresh tomato is 93.5 percent water. A fresh baby girl or boy is 75 percent water. A banana, 74 percent. We all start wet, and then, inevitably, dry. A 1-year-old baby carries 10 percent less water; a male adult 15 percent less. Life is a slow evaporation, with some curious exceptions.
