Immortal cells for tailor-made active substances


When scientists discover a new active substance, e.g. for use against a pathogen, they usually study its exact effect in cultured cells. But there is a lack of suitable test systems that simulate body tissues, because cells rapidly lose their specific properties once they are away from their ...

New sensor measures calcium concentrations deep inside tissue


Key processes in the body are controlled by the concentration of calcium in and around cells. A team from the Technical University of Munich (TUM) and the Helmholtz Zentrum München have developed the first sensor molecule that is able to visualize calcium in living animals with the help of a ...

Repetitive elements shape embryonic chromatin landscape


Retrotransposons are repetitive elements that form almost half of the mammalian genome. Even though they are so common, they have previously been considered to be fairly insignificant. Together with colleagues from the USA, scientists from the Helmholtz Zentrum München have now shown that ...

Periodic modulation tweaks innovative particle accelerators

New method can enhance beam quality of plasma cells


Scientists in Hamburg have come up with an ingenious way of improving so-called plasma accelerators, which are considered promising candidates to become the particle accelerators of the future. The quality of the electron beam produced by these innovative particle accelerators can be ...

New electron source for materials analysis


How can solar cells be made more efficient? How can solar and wind energy be best stored for later use? Technologies for the transformation of the German energy sector (Energiewende) require tailor-made materials which are both affordable and efficient. One important tool in the search for such ...

Nanoparticle Exposure Can Awaken Dormant Viruses


Nanoparticles from combustion engines can activate viruses that are dormant in in lung tissue cells. This is the result of a study by researchers of Helmholtz Zentrum München, a partner in the German Center for Lung Research (DZL). To evade the immune system, some viruses hide in cells of their ...

Here comes the long-sought-after iron-munching microbe


A microbe that ‘eats’ both methane and iron: microbiologists have long suspected its existence, but were not able to find it - until now. Researchers at Radboud University and the Max Planck Institute for Marine Microbiology in Bremen discovered a microorganism that couples the reduction of iron ...

Small heat shock protein as model for Alzheimer medication

New field of application for versatile helper


In Alzheimer’s disease proteins clump together to long fibrils causing the death of nerve cells. Small heat shock proteins can counteract this effect. Scientists, therefore, hope to deploy them as agents in the treatment of neurodegenerative diseases. Using the example of a small heat shock ...


Camera for the Nano-Cosmos


To gain even deeper insights into the smallest of worlds, the thresholds of microscopy must be expanded further. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the TU Dresden, in cooperation with the Freie Universität Berlin, have succeeded in combining two established ...


New infrared marker for bio-imaging


he recently developed fluorescent protein Amrose is now being used for advanced near-IR imaging procedures. With the aid of a novel evolutionary platform technology, scientists at the Helmholtz Zentrum München have developed this infrared marker as part of a combined effort to improve the quality ...
