Ghostly traces of massive ancient river revealed

Using zircon crystals, researchers have discovered the route of a massive ancient river that could help find new reservoirs of fossil fuels and suggest how modern rivers might change over time.

Ceramic holds promise for greener optical devices

A lead-free ceramic that could be used in applications ranging from optical sensors and switches to creams for protecting against ultraviolet (UV) light has been developed by A*STAR researchers.

Volcanic crystals give a new view of magma

Volcanologists are gaining a new understanding of what's going on inside the magma reservoir that lies below an active volcano and they're finding a colder, more solid place than previously thought, according to new research ...

How old is our moon?

Most scientists agree that the Earth has pretty much always had its moon. Details of the moon's composition (in particular the "isotopic mixture" of heavier and lighter versions of various elements) are too similar to the ...

The oldest crystals in the world

In this new article for Geology, Gavin Kenny and colleagues reveal the likely origin of Earth's oldest crystals. New research into the origin of Earth's oldest crystals suggests that they probably formed in huge impact craters ...

Scientists reveal likely origin of Earth's oldest crystals (Update)

New research suggests that the very oldest pieces of rock on Earth—zircon crystals—are likely to have formed in the craters left by violent asteroid impacts that peppered our nascent planet, rather than via plate tectonics ...
