New reaction facilitates drug discovery

Chemists at ETH Zurich have found a facile method that allows a commonly used building block to be directly converted into other types of important compounds. This expands the possibilities of chemical synthesis and facilitates ...

A quantum pump without a crank

Pumps, in a nutshell, are devices that use cyclic motion to attain the steady transport of some cargo. In a bicycle pump, the repeated up and down strokes of a piston create air flow. In a Archimedean screw pump, water is ...

A historical perspective on glacial retreat

Researchers at ETH Zurich and WSL have for the first time reconstructed the extent of Switzerland's glacier ice loss in the 20th century. For this purpose, the researchers used historical imagery and conclude that the country's ...

One more clue to the moon's origin

Humankind has maintained an enduring fascination with the moon. It was not until Galileo's time, however, that scientists really began study it. Over the course of nearly five centuries, researchers put forward numerous, ...

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 ...
