To probe a core p241 doi:10.1038/ngeo2935 Hidden under many kilometres of silicate mantle material, the cores of Earth and other planets are hard to investigate. The Psyche spacecraft, designed to visit a metal body that may be a core stripped of its mantle, could bring a close-up view.
Volcanology: Vulcan rule beneath the sea pp251 - 253 Deborah Kelley doi:10.1038/ngeo2929 Over 70% of the volcanism on Earth occurs beneath an ocean veil. Now, robotic- and fibre-optic-based technologies are beginning to reveal this deep environment and identify subaqueous volcanoes as rich sources of sulfur, carbon dioxide and life.
Electrification of sand on Titan and its influence on sediment transport pp260 - 265 J. S. Mendez Harper, G. D. McDonald, J. Dufek, M. J. Malaska, D. M. Burr et al. doi:10.1038/ngeo2921 Frictional charging of granular materials may readily occur on Saturn's moon Titan. Laboratory experiments under Titan-like conditions suggest that the resulting electrostatic forces are strong enough to affect sand transport on Titan.
