The differential diagnosis of nausea and vomiting is extensive and the underlying cause can be difficult to diagnose. Treatment of nausea and vomiting also can be unsatisfactory because the available pharmacotherapy does not correct the fundamental underlying pathophysiologic abnormalities. In contrast, the diagnosis of nausea and vomiting of pregnancy generally ...

The crustal remnants of Earth's Archean continents have been shielded from mantle convection by thick roots of ancient mantle lithosphere. The precise time of crust-root coupling (tectosphere birth) is poorly known but is needed to test competing theories of continental plate genesis. Our mapping and geochronology of an impact-generated section ...
