Atom or noise? New method helps cryo-EM researchers tell the difference

Cryogenic electron microscopy, or cryo-EM, has reached the point where researchers could in principle image individual atoms in a 3-D reconstruction of a molecule—but just because they could see those details doesn't always ...

Rust offers a cheap way to filter arsenic-poisoned water

When water flows deep underground, it often dissolves inorganic substances from mineral deposits in the earth's crust. In many regions, these deposits contain arsenic, a naturally occurring element that is colorless, tasteless ...

First detailed electronic study of new nickelate superconductor

The discovery last year of the first nickel oxide material that shows clear signs of superconductivity set off a race by scientists around the world to find out more. The crystal structure of the material is similar to copper ...
