Solar wind from the center of the Earth

High-precision noble gas analyses indicate that solar wind particles from our primordial Sun were encased in the Earth's core over 4.5 billion years ago. Researchers from the Institute of Earth Sciences at Heidelberg University ...

Making simulated cosmic dust—in the microwave

Cosmic dust is the key to the chemical evolution of stars, planets, and life itself, but its composition is not well understood, and we can't currently collect samples for analysis. A few examples have arrived on Earth as ...

Study looks to iron from microbes for climate help

Distributing iron particles produced by bacteria could "fertilize" microscopic ocean plants and ultimately lower atmospheric carbon levels, according to a new paper in Frontiers.

Cleaning up oil using magnets

In the future, it could be possible to remove oil spills on the surface of the ocean by using magnets. An interdisciplinary group of researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) led by Prof. Dr. ...

Hydrogen from water in iron nanotruss structures

Swedish researchers have discovered a new and efficient way to use electrocatalysis to produce hydrogen gas from water. Instead of using expensive and difficult-to-obtain platinum electrodes, the new method uses electrodes ...

Researchers study particulate matter in air samples

Current legal limits for fine dust in the air are based on the mass and size of the particles. For health effects, however, not only the amount of dust is decisive, but also its chemical composition. Empa researchers have ...

Taking MRI technology down to micrometer scales

Millions of magnetic resonance imaging (MRI) scans are performed each year to diagnose health conditions and perform biomedical research. The different tissues in our bodies react to magnetic fields in varied ways, allowing ...
