Manganese oxides are thought to be a signature of atmospheric oxygen. But on the Red Planet, recent results suggest they might be more of a red herring.
A mega-experiment in Brazil will evaluate how tropical rain forests absorb carbon as emissions increase.
Annual crops go dormant during winter. Frosty temperatures cue them to wake up—but the warmer winters brought on by climate change scramble the cold signal, hurting yield.
How was Earth’s early magnetic field produced? New experimental results and modeling show that the energy source could not have come from exsolution of lithophile elements from the core.
In July, Eos looks at the incredible capabilities scientists have developed to recreate the enormous pressures and temperatures that exist far below the planet’s surface.
How old is Earth’s inner core? High-pressure and high-temperature experiments suggest that our planet’s inner furnace may be much younger than expected.
Research fields focused on the physical properties of Earth materials emerged in the 20th century and have been making major contributions within geoscience ever since.
New research reveals a deep-sea mining experiment that took place 26 years ago still has significant and persistent impacts on benthic life.
Basin-wide ocean gyres have been observed to be slowly migrating toward the poles and, although natural variations contribute, climate simulations suggest the shift is in response to global warming.
Several dwarf galaxies orbiting the Milky Way were likely stolen from the Large Magellanic Cloud.
