Detecting dementia in the blood
Empa researcher Peter Nirmalraj wants to image proteins with unprecedented precision – and thus gain insights into the molecular pathogenesis of Alzheimer's. This should pave the way for an earlier diagnosis of the dementia disorder via a simple blood test. Together with neurologists from the Kantonsspital St.Gallen, a successful pilot study has now been completed.

X-ray microscopy with 1000 tomograms per second
A team at the Swiss Light Source SLS at PSI have set a new record using an imaging method called tomoscopy.The tomoscopy is an imaging method in which three-dimensional images of the inside of materials are reconstructed in rapid succession.

Research with animals, a necessity for scientific progress
Despite the many advancements in developing innovative alternative methods, animal testing still plays an important role in biological and medical research, enabling scientists to make new important discoveries. At EPFL, performing high-quality research is a priority for scientists, as is taking proper care of mice, rats and fish in the facilities.
