Half of the extraordinary heat of the Earth that erupts on its surface volcanically and drives the titanic motions of the continents is due to radioactivity, scientists find. This new discovery shows ...

Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved ...

Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

Our Earth is structured sort of like an onion – it's one layer after another. Starting from the top down, there's the crust, which includes the surface you walk on; then farther down, the mantle, ...

A flexible layered sulfide captures hydrated rare earth ions from radioactive water, enabling fast and selective cleanup while maintaining chemical stability and radiation resistance in a tunable ...

In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...

The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from the ...
