A Double-Edged Sword: The Global Oxychlorine Cycle on Mars
Global detections of oxychlorine salts reveal a complex, 4-billion-year chemical cycle on Mars. They can act as de-icing agents, oxidants, a hazard and a vital resource for future human exploration.

Tsunamis from the Sky
Not all tsunamis come from the seafloor, some are triggered by the atmosphere, driven by fast-moving storms and pressure waves, and can strike coasts with little warning.

How Glacial Forebulges Shape the Seas and Shake the Earth
A glacial forebulge is a bending-related upheaval of the lithosphere that has a strong effect on the sea level change pattern and on lithospheric stresses, which can induce intraplate earthquakes.
