In urban India, rising water scarcity and increasing pressure on water supply utilities have prompted the use of treated wastewater as an alternative source. A study of Eawag together with Indian partners explains how the use of sensors and automated chlorination can improve microbial water quality in on-site water reuse systems for increased user safety.

A 3D imaging method could be beneficial for heart transplant patients. Researchers at the Paul Scherrer Institute PSI and University Hospital Centre Zagreb in Croatia have shown that synchrotron radiation-based imaging of biopsy samples can reveal the extent to which the body is rejecting the transplanted organ. The new technique neatly supplements classical diagnostic methods. The researchers have published their findings in the medical journal Transplant International.

ETH students have developed sensors that can indicate how people use urban spaces. They anonymously measure how people use objects such as chairs in a public square. The sensors have proven useful in the test run and could be used in future to plan public spaces based on needs.

For a long time it has been suspected that fullerene and its derivatives could form naturally in the universe. These are large carbon molecules shaped like a football, salad bowl or nanotube. An international team of researchers using the Swiss SLS synchrotron light source at PSI has shown how this reaction works. The results have just been published in the journal Nature Communications.

In the Forest Laboratory "Waldlabor" on Hönggerberg, ETH Zurich researchers investigate the storage and transport processes of water in the forest. Recently they showed that forest-floor litter and deadwood have a far larger influence on the forest water balance than expected.
