An ancient volcano victim's brain turned to glass. Scientists now think they know how
To make glass from soft tissue the sequence of events must be exactly right. This is how experts think it went down ...

Surface roughness disrupts glass transition in colloidal ellipsoids, offering a new material design parameter
The so-called glass transition is the process by which some liquid-like materials become solid-like, without forming a crystalline structure. In contrast to conventional solid materials ...
Vesuvius Turned One Victim’s Brain to Glass
Heat from the eruption in A.D. 79 was so intense that it vitrified the brain tissue of one unfortunate Herculaneum resident, ...

Study: Hot Vesuvian ash cloud really did turn a brain to glass
This heated the guardian's brain to well above 510° Celsius—the glass transition temperature—which likely badly damaged the brain but did not destroy it. Rather, the brain fell into smaller ...

Big Chemistry: Glass
Humans have been chemically modifying their world for far longer than you might think. Long before they had the slightest idea of what was happening chemically, they were turning clay into bricks, ...

A new kind of phase transition?
On approaching the jamming transition, the dynamics becomes increasingly spatially heterogeneous, and strongly reminiscent of the behaviour of glass-forming liquids. Understanding the formation of ...

Phase transitions and critical phenomena articles from across Nature Portfolio
Understanding the behaviour of viscous liquids close to the glass transition is a century-old problem. The microscopic underpinnings of their mechanical response have now been made clearer by a ...
