New analyses of tiny fossil mammals from South Wales are shedding light on the function and diets of our earliest ancestors, a team led by researchers from the Universities of Bristol and Leicester report in the journal Nature. The team used CT scanning with synchrotron X-rays at PSI’s Swiss Light Source to reveal in unprecedented detail the internal anatomy of the mammals’ tiny jaws.

Phase contrast X-ray imaging has enabled researchers at ETH Zurich, the Paul Scherrer Institute (PSI) and the Kantonsspital Baden to perform mammographic imaging that allows greater precision in the assessment of breast cancer and its precursors. The technique could improve biopsy diagnostics and follow-up.

Scientists have used a particle accelerator to obtain high-speed 3D X-ray visualizations of the flight muscles of flies. The team from Oxford University, Imperial College, and the Paul Scherrer Institute (PSI) developed a groundbreaking new CT scanning technique at the PSI’s Swiss Light Source to allow them to film inside live flying insects. The movies offer a glimpse into the inner workings of one of nature’s most complex mechanisms, showing that structural deformations are the key to understanding how a fly controls its wingbeat.

A new mammography procedure that could generate substantial added value for the diagnosis of breast cancer in medical practice has just been published in the scientific journal “Investigative Radiology”. The method was developed at PSI in cooperation with the Certified Breast Centre at the Kantonsspital (cantonal hospital in) Baden and Philips as an industrial partner and is making the tiniest tissue changes visible. This has the potential to improve the early detection of breast cancer. Further studies in women suffering from breast cancer are to prove in a definitive manner the added value of the method.

Materials in lithium ion battery electrodes expand and contract during charge and discharge. These volume changes drive particle fracture, which shortens battery lifetime. A group of ETH and PSI scientists have quantified this effect for the first time using high-resolution 3D movies recorded using x-ray tomography at the Swiss Light Source.

Mit Hilfe von Röntgenlicht aus der Synchrotron Lichtquelle Schweiz des PSI ist es Paläontologen der Universität Bristol gelungen, ein Rätsel um den Ursprung der ersten Wirbeltiere mit harten Körperteilen zu lösen. Sie haben gezeigt, dass die „Zähne“ altertümlicher Fische (der sogenannten Conodonten) unabhängig von den Zähnen und Kiefern heutiger Wirbeltiere entstanden sind. Die Zähne dieser Wirbeltiere haben sich vielmehr aus einem Panzer entwickelt, der dem Schutz vor den Conodonten, den ersten „Raubtieren“, diente.

For the first time, experiments using computed tomography have allowed scientists to observe in 3D the flow of oil and water in real rock on an unprecedented scale. The new approach trailed and the information gathered by the experiments contribute to an improved understanding of multiphase flow and transport in porous media.

Researchers have succeeded in generating detailed three-dimensional images of the spatial distribution of amyloid plaques in the brains of mice afflicted with Alzheimer’s disease. The new technique used in the investigations provides an extremely precise research tool for a better understanding of the disease. In the future, scientists hope that it will also provide the basis for a new and reliable diagnosis method. The results were achieved within a joint project of two research teams – one from the Paul Scherrer Institute (PSI) and ETH Zurich, the other from the École Polytechnique Fédérale de Lausanne (EPFL).

Einzellige Organismen, die vor über einer halben Milliarde Jahre gelebt haben und deren Fossilien in China gefunden wurden, sind wohl die unmittelbaren Vorläufer der frühesten Tiere. Die amöbenartigen Einzeller haben sich in einer Weise in zwei, vier, acht usw. Zellen geteilt, wie es heute tierische (und menschliche) Embryonen tun. Die Forscher glauben, dass diese Organismen einem der ersten Schritte vom Einzeller zum Vielzeller in der Entwicklung richtiger Tiere entsprechen.

Reorganisation of the brain and sense organs could be the key to the evolutionary success of vertebrates, one of the great puzzles in evolutionary biology, according to a paper by an international team of researchers, published today in Nature. The study claims to have solved this scientific riddle by studying the brain of a 400 million year old fossilized jawless fish – an evolutionary intermediate between the living jawless and jawed vertebrates.

The Paul Scherrer Institute PSI has developed a new breast cancer diagnostic method, and is now carrying out first tests on non-preserved human tissue in conjunction with Kantonsspital Baden AG. This new method should be able to reveal structures that cannot be seen using conventional mammography. Scientists from the research department at Philips are currently investigating the use of this process as the basis for application in medical practice.
