For over two decades, physicists have been working toward implementing quantum light storage—also known as quantum memory—in ...

The oldest known material on Earth is a tiny bit of zircon crystal that has remained intact for an incredible 4.4 billion years, a study confirms.

A new series of experiments has shown that the mysterious "E-prime layer," which surrounds Earth's outer core, is created by water that leaks deep into our planet's interior.

To put that age in perspective, the Earth itself formed 4.5 billion years ago as a ball of molten rock, meaning that its crust formed relatively soon thereafter, 100 million years later.

New Curtin University research into the way rocks melt in the Earth's mantle layer has uncovered new properties of the key crystal spinel, suggesting previous studies that used it to study mantle ...

At 4.4 billion years old, a tiny zircon crystal about twice the size of a human hair is the oldest known piece of the Earth's crust. Found on a sheep ranch in western Australia over a dozen years ...
