New Earthquake Model Goes Against the Grain
Subducting plates are stronger in certain directions than others, which may be a factor in how earthquakes occur and how seismic waves propagate.

How Plant-Fungi Friendships Are Changing
A new framework shows how much carbon plants allocate to their endosymbionts and how that amount might change in the face of warming soil and rising carbon dioxide levels.

The Southern Ocean May Be Building Up a Massive Burp
Modeled results suggest that if anthropogenic emissions decrease and the atmosphere cools, heat stored in the Southern Ocean could be released abruptly in a few hundred years, kicking off a temporary warming period.
