When thawing glaciers release pollutants
When thawing glaciers release pollutants
Media Releases Energy and Environment Environment As glaciers increasingly melt in the wake of climate change, it is not only the landscape that is affected. Thawing glaciers also release many industrial pollutants stored in the ice into the environment. Now, within the scope of a Swiss National Science Foundation project, researchers from the Paul Scherrer Institute (PSI), Empa, ETH Zurich and the University of Berne have measured the concentrations of a class of these pollutants – polychlorinated biphenyls (PCB) – in the ice of an Alpine glacier accurately for the first time.

Media Releases Environment Energy and Environment The causes of China's record level fine particulate pollution in winter 2013 At the beginning of 2013 a greyish-brown blanket of smog lay over large areas of China for several months. The fine particle pollution was higher by 1 to 2 orders of magnitude than the levels normally measured in Western Europe and the United States.

Jurassic Welsh mammals were picky eaters, study finds
Media Releases Research Using Synchrotron Light 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 . 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.

Media Releases Research Using Synchrotron Light Materials Research Matter and Material Novel material shows properties necessary for spintronic devices The motion of electrons is at the heart of most electronic applications. However, in the quest for the next generation of devices, researchers are also interested in manipulating the electrons' spins – their traits that make them into tiny magnets.

Ice in fuel cells imaged directly for the first time
Media Releases Energy and Environment Researchers from the Paul Scherrer Institute (PSI) have succeeded in imaging the distribution of frozen and liquid water in a hydrogen fuel cell directly for the first time. They applied a new imaging technique that uses successively two beams with different neutron energies to distinguish between areas with liquid water and those with ice extremely reliably.

Media Releases Research Using Synchrotron Light World-record resolution in tomography with hard X-rays Tomography enables the interior of a vast range of objects to be depicted in 3D – from cellular structures to technical appliances. Researchers from the Paul Scherrer Institut (PSI) have now devised a method that opens up new scales of tomographic imaging and will thus make the detailed study of representative volumes of biological tissue and materials science specimens possible in future.
