Explaining the Missing Energy in Mars’s Electrons
Electrons energized and trapped at Mars were thought to lose energy inside the planet’s magnetosheath, but new research suggests a different explanation of spacecraft data.

Where Does the Carbon Go When Permafrost Coasts Erode?
Arctic coastlines have not been considered carefully in carbon cycles for long, but new research suggests that eroding permafrost may emit more greenhouse gases than previously thought.

Earthquake Statistics Vary with Fault Size
A theoretical study explores why small earthquake sources can produce quasiperiodic sequences of identical events, whereas earthquakes on large faults are intrinsically more variable.

How Are Microplastics Transported to Polar Regions?
New modeling indicates that global subsurface ocean currents distribute submerged microplastics along very different routes than those traveled by floating plastic debris.
