Heat waves thawing Arctic permafrost

In the northernmost region of the earth the arctic permafrost is melting at an accelerated rate. For more than a decade, an international team of researchers from ETH Zurich, the University of Alaska Fairbanks, and the German ...

Imaging the brain with ultrasound waves

Both ultrasound for medical imaging and seismology for imaging the Earth's interior measure the propagation of waves through matter. For example, when seismic waves encounter material differences in the Earth's interior, ...

Attosecond measurement on electrons in water clusters

Virtually all vital chemical processes take place in aqueous solutions. In such processes, a decisive role is played by electrons that are exchanged between different atoms and molecules and thus, for instance, create or ...

Researchers remeasure gravitational constant

The gravitational constant G determines the strength of gravity—the force that makes apples fall to the ground or pulls the Earth in its orbit around the sun. It is part of Isaac Newton's law of universal gravitation, which ...

New insights into the Earth's formation

Although the Earth has long been studied in detail, some fundamental questions still have to be answered. One of them concerns the formation of our planet, about whose beginnings researchers are still unclear. An international ...
