During the course of Alzheimer's disease, protein fibrils appear in the spinal fluid of affected individuals. Empa researchers, together with the Department of Neurology at the Cantonal Hospital in St. Gallen, have now visualized the wide spectrum of protein aggregates from oligomers, protofibrils to fibrils in the spinal fluid. The conclusion: Ultra-long protein fibrils are a signature of severe Alzheimer’s disease. The study, recently published in Communications Biology, sheds light into the delicate role of protein aggregation in the development of Alzheimer's disease and is expected to improve early detection of dementia.

Can ecologically sustainable circuit boards for the electronics industry be produced from cellulose fibers? Empa researcher Thomas Geiger looked into this question. He is now part of a multinational EU project called "Hypelignum". Its goal: biodegradable electronics.

Their task is to monitor the condition of ecosystems, for instance in the forest floor – and crumble to dust when their work is done: bio-gliders modeled on the Java cucumber, which sails its seeds dozens of meters through the air. Empa researchers have developed these sustainable flying sensors from potato starch and wood waste.

JUICE, the European spacecraft that is scheduled to launch later today, will explore Jupiter and its icy moons. Some of the components on board have been manufactured at Empa using a specially developed soldering process.

A new analysis has found rapidly increasing emissions between 2010 and 2020 of five ozone-depleting chemicals whose production for most uses had been banned under the Montreal Protocol. The emissions of these five chlorofluorocarbons, or CFCs, occur in part from leakage during the synthesis of ozone-friendly alternatives to CFCs. Even though such by- or intermediate product emissions are allowed as an exception under the Montreal protocol, they are contrary to its wider goal – and the observed increases rise concerns.
