Examining tissues, cells, and proteins under a microscope helps us prevent and combat diseases. To study this, we need to precisely determine the dimensions of the biological structure. However, a biological sample may appear flatter under the light microscope than it actually is. Researchers at Delft University of Technology have now demonstrated for the first time that this distortion is not constant, contrary to what many scientists have assumed for decades. The breakthrough, published in Optica, confirms a prediction by Nobel laureate Stefan Hell from the 90s. With an online calculation tool and software, every researcher can now determine the correct depth of a biological sample.

High waves startle mangroves for days during an experiment at the Delta wave flume in Delft. Researchers from Deltares and TU Delft keep increasing the force on the trees. They test how strong the mangrove trees are under extreme wave conditions and what contribution they make to water safety.
