Turbulent times revealed on Asteroid 4 Vesta

Planetary scientists at Curtin University have shed some light on the tumultuous early days of the largely preserved protoplanet Asteroid 4 Vesta, the second largest asteroid in our Solar System.

Getting to the root of carbon storage in deep soils

Land use changes, nutrient depletion, and drought can make plant roots grow deeper into the soil. But scientists question how that growth affects carbon in the soil. Could more roots reaching deep soil layers result in more ...

Scientists discover ancient seawater preserved from the last Ice Age

Twenty thousand years ago, in the thick of an Ice Age, Earth looked very different. Because water was locked up in glaciers hundreds of feet thick, which stretched down over Chicago and New York City, the ocean was smaller—shorelines ...

Agrochemists find proof of the ferrous wheel hypothesis

A team of agrochemists from Russia, Germany, and Chile confirmed the so-called ferrous wheel hypothesis—the turnover of iron in the soil that enriches it with organic nitrogen. The results of the study were published in ...

Subglacial weathering alters nutrient cycles in Greenland

The nutrient cycles that underpin how carbon is stored and released from two of Greenland's glaciers is significantly affected by subglacial weathering, a new study has found, shedding further light on the geochemistry of ...
