Bewegung ist Leben - das Antriebssystem der Zellen

Viele Zellen sind zu aktiver Bewegung faehig. Sie benutzen dazu einen inneren Antrieb mit Recycling-Funktion. Forschern gelang es mittels Kryo-Elektronentomographie, den Vorgang buchstaeblich einzufrieren und den molekularen Motor wirklichkeitsgetreu darzustellen.

Lensless imaging of whole biological cells with soft X-rays

A team of scientists working at beamline 9.0.1 of the Advanced Light Source (ALS) at the Lawrence Berkeley National Laboratory has used x-ray diffraction microscopy to make images of whole yeast cells, achieving the highest resolution - 11 to 13 nanometers - ever obtained with this method for biological specimens.

New electrolytic cells to play a role in tomorrow's local energy supply

Lower CO2 emissions demand more renewable energy in the energy system. This calls for new solutions that take account of the considerable variations in the amount of wind energy, hydropower, solar energy etc. One of the solutions is a distributed energy system. Here it must be possible to store surplus energy locally using, for example, local SPEC electrolytic cells. The foundation for this technology is being developed by the CASE research project.
