Clickbait. Please provide a title that says who and what material.

"Scientists synthesize material that may replace rare earth magnets"

("who" was two universities, so didn't fit a title).

And ... not quite correct. The paper at https://onlinelibrary.wiley.com/doi/10.1002/advs.202204315 even says "Tetrataenite has been found as a terrestrial mineral".

That (second) paper, at https://www.degruyter.com/document/doi/10.2138/am-2015-5061/... , says:

> Here we report the characteristics of terrestrial tetrataenite from an ophiolite-hosted Ni-bearing magnetite body from the Indo-Myanmar ranges, northeast India. Although the mineral assemblage surrounding it is very similar to that found in the meteorites, the postulated cooling regimes cannot be similar. The mineral is formed as a consequence of hydrothermal alteration of ferromagnesian minerals of the olivine and pyroxene groups.

they managed to manufacture, in a lab, a material that does not exist naturally on Earth

What crap. Half the stuff that's made today 'does not exist naturally on Earth'.

When was the last time you saw natural polystyrene? Or natural bone china? or natural stainless steel? Or natural cellophane? Etc, etc, etc.

They made a material found in meteorites that can replace rare earth magnets with nickel and iron.

If I read the article correctly, it should be: '[...] that could replace rare earth magnets with nickel and iron.'

This is a call to funding type of article promising one of those many right-around-the-corner technical revolutions that might never happen.
