Science 2.0 (June 25) -- New research suggests that wood mice, commonly found in Europe, have a built-in compass that exploits quantum processes, the first seen in a wild mammal. Theorists see the study as a solid, early step toward a better understanding of the quantum compass, which has also been observed in amphibians. In fact, Klaus Schulten – the Illinois biophysicist who first hypothesized this compass setup – says that "there is no element of surprise" to Malkemper's discovery, given what's been found already in non-mammals.
