Birds may find way with cognitive map A bird known as Clark's nutcracker can learn to navigate according to the geometric relationship between pairs of landmarks to find seed-storage sites, suggesting that it uses mental representations of its surroundings. The seed-storing corvid Clark's nutcracker learns geometric relationships among landmarks. Protein shells out guidance to crystals A specially synthesized protein that controls the growth of calcite could help researchers understand how mollusks make their shells. Control of calcite crystal morphology by a peptide designed to bind to a specific surface. Morse, D.E., et al. 1997.
