A pair of researchers with Dartmouth College has found that Pacific hermit crabs use vibration to ward off other crabs trying to steal their shells. In their paper published in the journal Biology Letters, Louise Roberts ...
A chemical reaction transforms the molecules that make up matter. To influence chemical reactions, chemists typically act on the molecules themselves, rather than the space in which the reaction takes places. However, researchers ...
