When assembling a jigsaw puzzle, just shaking up the box and dumping the pieces in a pile probably isn’t the best strategy. The pieces won’t fit themselves together by chance. But in the nanoworld, this approach could prove surprisingly fruitful. It might take the fun out of doing the puzzle, but scientists are now figuring out how to make the pieces move, on their own, into the desired positions for creating new materials. In this case, the puzzle pieces are nanoparticles, tiny collections of atoms smaller than one ten-thousandth of a millimeter across. Properly guided, these particle...

From Danny Devito to Yao Ming, the world is filled with short people and tall people and everyone in between. While factors such as nutrition influence height differences, much of that variation depends on genes. After all, both of Ming’s parents were basketball stars, and Devito’s were not. But the genes that made Ming grow to 7 feet 6 inches and Devito stop growing several feet shorter could be important for more than sports. Changes in how height genes work could not only add or subtract a few centimeters from leg length, but could also affect underlying cell biology in ways that ca...
