Bits of plant life encapsulated in molten glass by asteroid and comet impacts millions of years ago give geologists information about climate and life forms on the ancient Earth. Scientists exploring large fields of impact glass in Argentina suggest that what happened on Earth might well have happened on Mars millions of years ago. Martian impact glass could hold traces of organic compounds.

Technologically valuable ultrastable glasses can be produced in days or hours with properties corresponding to those that have been aged for thousands of years, computational and laboratory studies have confirmed.

We can look through glass, but what glass itself looks like on the inside has so far remained a mystery - at least as far as the precise position of the atoms is concerned. Scientists at the Fritz-Haber-Institute of the Max Planck Society in Berlin are now the first to have imaged the network of silicon and oxygen atoms - the main components of glass - in a silica film.

One of the most instantly recognizable features of glass is the way it reflects light. But a new way of creating surface textures on glass, developed by researchers at MIT, virtually eliminates reflections, producing glass that is almost unrecognizable because of its absence of glare — and whose surface causes water droplets to bounce right off, like tiny rubber balls.

When chemists look at a drinking glass filled with water and a few ice cubes, it's not clear to them whether the glass is more like the water or the ice. Glass is one of civilization's most valuable and versatile materials. To scientists, it's also one of the most intriguing, because it displays properties of both solids and liquids.

The nature of a glass is a debate that runs far deeper than whether one appears half empty or half full. For years scientists have known that the atoms and molecules in glasses arrange themselves randomly, like the non-uniform pattern of particles in a liquid. What’s puzzling, though, is that while the molecules in a glass are arranged like in a liquid, the overall structure is solid.
