Auf der Spur der Medikamententaxis

Wie gelangen Krebsmedikamente sicher an ihr Ziel? Ein internationales Forschungsteam hat an der Röntgenlichtquelle PETRA III eine Methode getestet, die die Verteilung eines Wirkstoffs in Tumorzellen sichtbar machen kann. In Zukunft könnte der Ansatz helfen, zielgerichtetere und damit effektivere Krebstherapien zu...

Watching protein cross-linkers break – and reform remarkably fast

An international team of scientists has used extremely short X-ray flashes to understand the first steps in the light-induced breaking of disulfide bridges – the natural cross-linkers that hold most protein structures in place. The study, published in the journal “Nature Communications”, followed the change in X-ray...

Mystery of Supersonic Turbulence Solved

Which clumps of interstellar gas will collapse under gravity to form stars and which clumps will not? This is related to a key problem in turbulence: to understand the distribution of densities produced. Using simulations and analytic work, researchers have been able to both track and model the evolution of densities under...

Paenilamicins represent a promising new class of antibiotics

Paenilamicins are compounds that are effective against various bacterial pathogens. Researchers led by the Department of Chemistry at the University of Hamburg have now elucidated the mechanism of these compounds. The results make paenilamicins an attractive class of compounds for the development of novel antibiotics and...
