Using Hematite to Decipher Past Climates and Environments
The magnetic and color properties of the mineral hematite give clues to past environmental conditions and is being used for paleoclimatic reconstruction.
Microplastics Morph Cell Metabolism
Microplastics get into our bodies, potentially altering how certain cells convert sugar into energy, especially in the gut. Continued ingestion could cause chronic problems.
A Simple Recipe for Making the First Continental Crust
Laboratory experiments serendipitously revealed a rock-forming process that might explain how the first continental crust formed on Earth—and possibly on Mars.
An Explanation, at Last, for Mysterious “Zen Stones”
Laboratory experiments re-create the thin, icy pedestals that support some rocks in nature, revealing that sublimation plays a key role in the formation of these rare and beautiful structures.
Melting Arctic Sea Ice Strengthens Tides
If climate change throws off the seasonal freeze-thaw cycle of sea ice, it could trigger a reinforcing cycle of sea ice melt in parts of the Canadian Arctic.
Adapting to Receding Glaciers in the Tropical Andes
Integrated approaches are needed to understand and respond to changes in tropical mountain ecosystems and communities brought about by receding glaciers and changes in land use.
Chinese Architecture Evolved with Changes in Snowfall
Roof design in northern China changed over centuries in response to extreme snow events, new research suggests.
Evolving the Geodetic Infrastructure
Enhancements to the largely invisible framework will enable researchers to investigate pressing questions about our planet’s future.
Tiny Kinks Record Ancient Quakes
As Earth ruptures, micas kink. These kink bands hide in rocks millions of years old, preserving evidence of past quakes.
Where Do the Metals Go?
Volcanic eruptions spread harmful metals in the environment. Now the biggest study to date details exactly where they end up.
