Why Are There Different 'Flavors' of Iron Around the Solar System?

133596_web.jpg

New work shows that interactions between iron and nickel under the extreme pressures and temperatures similar to a planetary interior can help scientists understand the period in our Solar System's youth when planets were forming and their cores were created.

Climate-Driven Permafrost Thaw

133573_web.jpg

In bitter cold regions like northwestern Canada, permafrost has preserved relict ground-ice and vast glacial sedimentary stores in a quasi-stable state. These landscapes therefore retain a high potential for climate-driven transformation.

Old Rocks, Biased Data: Overcoming Challenges Studying the Geodynamo

Paleonitrogenhoriz_1.jpg

Bias introduced through analyzing the magnetism of old rocks may not be giving geophysicists an accurate idea of how Earth's magnetic dynamo has functioned. A team led by Michigan Technological University shows there is a way to improve the methodology to get a better understanding of the planet's geodynamo.

Climate Change Prompts Alaska Fish to Change Breeding Behavior

A new University of Washington study finds that one of Alaska’s most abundant freshwater fish species is altering its breeding patterns in response to climate change, which could impact the ecology of northern lakes that already acutely feel the effects of a changing climate.

Heat From Earth’s Core Could Be Underlying Force in Plate Tectonics

NewimagefromRowley1-9-17.png

For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the additional force of heat drawn from the Earth’s core. The new findings also challenge the theory that underwater mountain ranges known as mid-ocean ridges are passive boundaries between moving plates. The findings show the East Pacific Rise, the Earth’s dominant mid-ocean ridge, is dynamic as heat is transferred.

Study of Microbes Reveals New Insight About Earth’s Geology and Carbon Cycles

Subsurface-microbiome_900px.jpg

Tiny microbes play a big role in cycling carbon and other key elements through our air, water, soil and sediment. Researchers who study these processes at Argonne National Laboratory have discovered that these microbial communities are significantly affected by the types of carbon “food” sources available. Their findings reveal that the type of carbon source affects not only the composition and activity of natural microbial communities, but also in turn the types of mineral products that form in their environment.
