Principles of limb regeneration in salamanders show link to mammals

01-Oct-2018 - Scientists have long argued over which cells enable salamanders to grow back lost limbs. By tracking lineages and characterising individual cells, researchers could now show that connective tissue cells develop stem-cell-like properties and underlie the regeneration of legs. Among all four-legged ...

The largest genome ever

Decoding the Axolotl

26-Jan-2018 - A team of researchers led by scientists in Vienna, Dresden and Heidelberg has decoded the entire genetic information of the Mexican salamander axolotl. The axolotl genome, which is the largest genome ever to be sequenced, will be a powerful tool to study the molecular basis for re-growing limbs ...

Watching Molecular Machines at Work

15-Aug-2016 - An international team of scientists from Austria, Germany and the US has combined newly developed techniques in electron microscopy and protein assembly to elucidate how cells regulate one of the most important steps in cell division. When one cell divides into two - that is how all forms of life ...

Zooming in on the Weapons of Salmonella

08-Mar-2011 - Bacteria like salmonellae infect their host cells by needle-shaped extensions which they create in large numbers during an attack. A group of Vienna-based scientists headed by Thomas Marlovits employed recently developed methods of cryo-electron microscopy and have been able to clarify the ...
