Scientists have discovered that shear forces inside rising magma can create gas bubbles long before pressure drops occur. The ...

Learn how stress inside a volcano can make gas bubbles form early, helping explain why some eruptions stay quiet instead of ...

For decades, volcanologists believed that the primary trigger for explosive eruptions was a drop in pressure as magma rises ...

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles ...

A new study explains why even gas-rich, supposedly explosive volcanoes sometimes erupt quietly instead of blowing apart.

Models that inform how magma moves and volcanic eruptions unfold may need an update, according to a new study. It reports that gas bubbles in magmas can form through the mechanical forces of shear as ...

Advances in materials science have led to the development of "smart materials," whose properties do not remain static but ...

The force needed to slide sheets of graphene across each other has been measured using a new technique that involves blowing air bubbles made of the material. Developed by Zhong Zhang of the National ...
