Astronomy: A rotating system of satellite galaxies raises questions

Astronomers have examined the distribution and movement of dwarf galaxies in the constellation Centaurus, but their observations do not fit with the standard model of cosmology that assumes the existence of dark matter. The international team of researchers led by the University of Basel reported their findings in the journal Science.

Optical nanoscope allows imaging of quantum dots

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.

Low-temperature record 2.8 mK reached in a nanoelectronic device

With on-and-off chip magnetic cooling techniques a team around Dominik Zumbühl achieved to cool a Coulomb blockade thermometer - a nanoelectronic device - to the low-temperature record of 2.8 mK! This research opens the doors for new low temperature physics and was therefore chosen as an editor's pick in Applied Physics Letters. In addition, this work was also covered in a Scilight article.

A nanoscale balance for individual cells

An interdisciplinary team from the University of Basel, ETH Zurich, and University College London have developed a new method that can be used to analyze individual live mammalian cells within a cell assembly. Based on a system of tiny cantilever probes, the technique records the cell mass over several days in millisecond steps and is accurate to within a few picograms. Using the new technique, the scientists have been able to observe for the first time that the cell mass fluctuates within the space of a few seconds. These findings and the new platform provide fundamental insights into the regulation of cell mass and into how this is disrupted in the event of illness. The study was presented today in the journal Nature.

Interview with Friedrich Thielemann on the collision of neutron stars detected by LIGO for the first time

Just als der Basler Astrophysiker Friedrich Thielemann den Wissenstand über die Verschmelzung von Neutronensternen in einem Übersichtsartikel zusammenfasste, konnten Forscher das astronomische Ereignis erstmals beobachten. Im Interview beschreibt er, wie Vorhersagen und Beobachtungen zusammenpassen und weshalb das Ereignis unser Verständnis des Universums verändern wird.

Quantum sensors decipher magnetic ordering in a new semiconducting material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
