How nitrogen-fixing bacteria sense iron

Researchers at the University of East Anglia have discovered how nitrogen-fixing bacteria sense iron—an essential but deadly micronutrient.

Using ultracold atoms to find WMDs

One problem in dealing with weapons of mass destruction is that they are well hidden. The key to finding them may be to change the methods we use to look. One such method is taking shape in a lab in the basement of Small ...

Researchers detect bromine atoms in springtime Arctic

For the first time, researchers at the University of Michigan have detected bromine atoms in the atmosphere, and in doing so, have confirmed the reaction pathway through which mercury is removed from the atmosphere and enters ...

Scientists dissolve crude oil in water to study its composition

Researchers from MIPT, Skoltech, the Joint Institute for High Temperatures of the Russian Academy of Sciences, and Lomonosov Moscow State University report a new approach to oil composition analysis. They used high temperature ...

A novel synchrotron technique for studying diffusion in solids

Understanding and controlling how the diffusion process works at the atomic scale is an important question in the synthesis of materials. For nanoparticles, the stability, size, structure, composition, and atomic ordering ...

The Milky Way is warped

The Milky Way galaxy's disk of stars is anything but stable and flat. Instead, it becomes increasingly warped and twisted far away from the Milky Way's center, according to astronomers from National Astronomical Observatories ...
