(PhysOrg.com) -- In a recent study, researchers have examined the possibility of rolling a nanorod on the surface of water. On the macroscale, perhaps the closest analogy might be the sport of logrolling, in which two competitors ...
In a compost heap, the nematode Caenorhabditis elegans finds a richly laid table: at a length of just one millimeter, the worm feeds on bacteria that decompose organic material. It is essential that the animal avoids sunlight—and ...
