Magnetic fields help target buried mine waste for removal

Thousands of geese have died in the toxic, acidic waters of Montana's Berkeley Pit, signaling the spread of heavy metals and acid into the city's of Butte's groundwater, according to new research presented at the 2016 American Geophysical Union Fall Meeting.

Finger-like structures on Mars could be the result of ancient microbes

Finger-like rock structures on Mars could harbor potential evidence of past life on the Red Planet, according to new research presented at the 2016 American Geophysical Union Fall Meeting.

The meeting that gave birth to the idea of global tectonics

Fifty years ago, scientists began to connect details of an idea with profound implications: Earth's ocean crust recycles itself on a global scale, and continents move across the face of the planet.

Buzzing ice shelf makes waves in the air above

The resonant vibrations of the Ross Ice Shelf in Antarctica are disturbing the atmosphere above it and creating huge ripples, according to a new study in the Journal of Geophysical Research: Space Physics.

Reading raindrops: microphysics in Typhoon Matmo

Quantitative predictions about tropical storms require an understanding of even their smallest physical processes. A new study from the Journal of Geophysical Research: Atmospheres observes unusual microphysics in 2014's Typhoon Matmo.

Earth's ground heat flux should not be overlooked

In a new study from the Journal of Geophysical Research: Biogeosciences, scientists compare models of how much heat Earth's surface gives off and absorbs from the atmosphere.

Dispatch 6: Strange Times
Covid has disrupted the most basic routines of our days and nights. But in the middle of a conversation about how to fight the virus, we find a place impervious to the stalled plans and frenetic demands of the outside world. It's a very different kind of front line, where urgent work means moving slow, and time is marked out in tiny pre-planned steps. Then, on a walk through the woods, we consider how the tempo of our lives affects our minds and discover how the beats of biology shape our bodies.
