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.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
