Scientists uncovered how seasonal changes affect the amount and rate of carbon as it moves from the ocean’s surface to its depths.

Ocean thermal energy conversion could power the world’s tropical islands, if it ever gets out of the “innovation valley of death.”

How did our planet avoid being frozen solid during the early days of our solar system?

Two recently published papers zoom in on the mystery source of methane in the Martian atmosphere.

The magnetic and color properties of the mineral hematite give clues to past environmental conditions and is being used for paleoclimatic reconstruction.


Microplastics get into our bodies, potentially altering how certain cells convert sugar into energy, especially in the gut. Continued ingestion could cause chronic problems.

Laboratory experiments serendipitously revealed a rock-forming process that might explain how the first continental crust formed on Earth—and possibly on Mars.

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.


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.

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.
