During their migration, cerebellar granule cells switch from a tangential to a radial mode of migration. We have previously demonstrated that this involves the transmembrane semaphorin Sema6A. We show here that plexin-A2 is the receptor that controls Sema6A function in migrating granule cells. In plexin-A2-deficient (Plxna2(-/-)) mice, which were generated(More)

With a radius of 1200 km the Earth's inner core is only 30% smaller than its moon. Being the solid, central core of a planet, its dynamics are fascinating and unique. The inner-core boundary is a solid– liquid phase boundary, where the geotherm crosses the liquidus temperature of the iron alloy that comprises the Earth's core. The solidity of the inner core(More)
