NPR reports that "two teams of scientists — one at Northeastern University in Boston; the other at the University of Cambridge in the UK — recently announced that they managed to manufacture, in a lab, a material that does not exist naturally on Earth."

"It — until now — has only been found in meteorites."

We spoke to Laura Henderson Lewis, one of the professors on the Northeastern team, and she told us the material found in the meteorites is a combination of two base metals, nickel and iron, which were cooled over millions of years as meteoroids and asteroids tumbled through space. That process created a unique compound with a particular set of characteristics that make it ideal for use in the high-end permanent magnets that are an essential component of a vast range of advanced machines, from electric vehicles to space shuttle turbines.

The compound is called tetrataenite, and the fact that scientists have found a way to make it in a lab is a huge deal. If synthetic tetrataenite works in industrial applications, it could make green energy technologies significantly cheaper. It could also roil the market in rare earths, currently dominated by China, and create a seismic shift in the industrial balance between China and the West....

But it will be a long time before tetrataenite is in a position to disrupt any existing markets, Laura Lewis says. She says there is still a lot of testing to be done to find out whether lab tetrataenite is as hardy and as useful as the outer space material. And even if it turns out to be as good, it will be five to eight years "pedal to the metal" before anyone could make permanent magnets out of it. In the meantime, China's competitors are working hard to source rare earths of their own. The US is investing in mines in Australia; there's exploration ongoing in Malaysia, and the Japanese are researching ways to extract elements from mud mined from the sea bed.
