PSI

Researchers at the Paul Scherrer Institute PSI, in collaboration with ETH Zurich, have optimised a method for tumour diagnosis using radionuclides. Potential side-effects can now be significantly reduced through a molecular trick. The researchers report their results in the current issue of the scientific journal Bioorganic & Medicinal Chemistry.

At a conference the international ice core science community discusses the latest developments in their field.

For over 25 years PSI has been conducting an uninterrupted series of measurements on the Jungfraujoch, studying the impact of aerosols on our climate at 3,580 metres above sea level. The measurements are taken in the Sphinx Observatory, the landmark building on the Jungfraujoch, inaugurated in 1937. This is Europe’s highest research station that can be reached throughout the year via the legendary mountain railway, the Jungfraubahn.

Safely packed in a sturdy wooden crate, a high-tech component from PSI has begun its journey to Australia. The device was in use at PSI for more than ten years – now, with the commissioning of the Swiss X-ray free-electron laser SwissFEL, it has reached the end of its service life and will be given a new task at the Australian Synchrotron in Melbourne.

It has recently been supposed that humans could trace their ancestry back to a strange microscopic creature with a mouth and no anus. Thanks to analysis of 500 million year old fossils at the Swiss Light Source SLS, we can be relieved to find out this is not true: Saccorhytus is not a deuterostome like us, but an ecdysozoan. The findings, published today in Nature, make important amendments to the early phylogenetic tree and our understanding of how life developed.
