How flies flip around on take-off from an upside- down position

Flies are able to right themselves very quickly when taking off from an upside-down position. Scientists from the CNRS and from The Institute of Movement Science (ISM) at Aix-Marseille Université studying this phenomenon ...

Orientation of protein patterns

During embryogenesis in the nematode Caenorhabditis elegans, the first cell division occurs transverse to the long axis of the fertilized egg. In a new study, biophysicists at LMU have now shown how this axis is reliably ...

The riddle of the heavenly bursts

This cosmic lightning storm is happening all around us. Somewhere in the earthly sky, there is a pulse that flashes and extinguishes in the next moment. These bursts, which must be measured with radio telescopes and last ...
