Research by Austrian geneticists has raised the possibility that stem cells could be isolated from amniotic fluid – the protective bath water that surrounds the unborn baby.
Geneticist Professor Markus Hengstschläger and his team at the University of Vienna have isolated a subgroup of cells from amniotic fluid that express a protein called Oct-4 – known to be a key marker for human pluripotent stem cells.
Reporting the findings today (Monday 30 June) in Europes leading reproductive medicine journal Human Reproduction, Professor Hengstschläger stressed that the investigation was at an early stage. A lot more work had to be done to verify the finding, and tests were now under way to establish in which direction the cells could be differentiated. However, preliminary experiments have already provided evidence that they can be differentiated into nerve cells.

The MICADO camera, a first light instrument for the European Extremely Large Telescope (E-ELT), has entered a new phase in the project: by agreeing to a Memorandum of Understanding, the partners in Germany, France, the Netherlands, Austria, and Italy, have all confirmed their participation. Following this milestone, the project's transition into its preliminary design phase was approved at a kick-off meeting held in Vienna. Two weeks earlier, on September 18, the consortium and the European Southern Observatory (ESO), which is building the telescope, have signed the corresponding collaboration agreement.
As the first dedicated camera for the E-ELT, MICADO will equip the giant telescope with a capability for diffraction-limited imaging at near-infrared...
Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.

In cooperation with the Center for Nano-Optics of Georgia State University in Atlanta (USA), scientists of the Laboratory for Attosecond Physics of the Max Planck Institute of Quantum Optics and the Ludwig-Maximilians-Universität have made simulations of the processes that happen when a layer of carbon atoms is irradiated with strong laser light.
Electrons hit by strong laser pulses change their location on ultrashort timescales, i.e. within a couple of attoseconds (1 as = 10 to the minus 18 sec). In...
