Ferroelectric switching of a two-dimensional metal p.336

Two- and three-layer WTe2 exhibits spontaneous out-of-plane electric polarization that can be switched electrically at room temperature and is sufficiently robust for use in applications with other two-dimensional materials.

Categorical perception of colour signals in a songbird p.365

Female zebra finches exhibited categorical perception of colour signals, as they categorized colour stimuli that varied along a continuous scale and showed increased discrimination between colours from opposite sides of the category boundary compared to equally different colours from within a category.
