Drawing on more than a century of science, our multidisciplinary department discovers exoplanets, creates new materials, illuminates Earth's inner workings, and seeks to better understand the universe ...

Earth's magnetic field is generated by the motion of liquid iron in the planet's core. This “geodynamo” occasionally reverses its polarity—the magnetic north and south poles swap places. The switch ...

Oxygen isotopic compositions of silicates in eclogites and whiteschists from the Kokchetav massif were analyzed by whole-grain CO2-laser fluorination methods. Systematic analyses yield extremely low ...
