The mantle transition zone (MTZ), which occurs 410–670 kilometers below Earth's surface, may store several oceans' worth of water. This water, which is carried to such depths by subducting tectonic ...

Researchers from the UAB and the Max Planck Institute for Social Anthropology have identified the economic and political ...

During this campaign, we successfully conducted 12 laser shots on a specially designed tiny, embedded wire to simulate the conditions close to the core-mantle boundary of rocky planets. These ...

The Picker Interdisciplinary Science Institute (Picker ISI) has announced this year’s awards supporting interdisciplinary approaches in innovative research. The awards bring together Colgate faculty ...

Deep beneath the Earth’s surface, researchers have uncovered striking new evidence of ancient seafloor buried for millions of ...

Where the Earth’s core meets the mantle, there are two giant regions that have baffled geologists for fifty years. A new ...

Do empires have to have a metropole? Why? How and when does a core form and a boundary emerge between it and a periphery? How is that boundary (spatial and symbolic) contested and when does it move?

Earth’s mantle is the thick layer between the crust and the core. It includes a graveyard of subducted ... These small particles cause waves to lose more energy because the wave boundaries are more ...

This is caused by the connection between the topography of the core-mantle boundary and mantle density anomalies. Changes near the edge of the inner core are likely the result of such deformation ...

Credit: Li et al. [2025], Figure 10 Throughout Earth’s history, heat flow from the core into the base of the mantle should have occasionally destabilized the bottom boundary and launched thermal ...
