Image Analysis: Automatic Tracking of Biological Particles in Cell Microscopy Images

In order to track the movements of biological particles in a cell, scientists at Heidelberg University and the German Cancer Research Center have developed a powerful analysis method for live cell microscopy images. This so-called probabilistic particle tracking method is automatic, computer-based and can be used for time-resolved two- and three-dimensional microscopy image data. The Heidelberg method achieved the best overall result in an international competition that compared different methods for image analysis. The competition results were recently published in the journal Nature Methods.

3D X-Rays Film inside Live Flying Insects

Scientists have used a particle accelerator to obtain high-speed 3D X-ray visualizations of the flight muscles of flies. The team from Oxford University, Imperial College, and the Paul Scherrer Institute (PSI) developed a groundbreaking new CT scanning technique at the PSI's Swiss Light Source to allow them to film inside live flying insects. Their article, including 3D movies of the blowfly flight motor, is published in the open access journal PLOS Biology. The movies offer a glimpse into the inner workings of one of nature's most complex mechanisms, showing that structural deformations are the key to understanding how a fly controls its wingbeat (see videos).

4D Live Imaging of the Cellular Shipping Port

The epithelium lines the organs of the human body. In the skin and the intestine as well as in the kidney, this cell layer forms a barrier that regulates the exchange of molecules like hormones and nutrients. The Freiburg biophysicist Dr. Roland Thünauer and junior professor Dr. Winfried Römer, Institute of Biology II and member of the Cluster of Excellence BIOSS Centre for Biological Signalling Studies of the University of Freiburg, have discovered a new mechanism by which proteins are transported to the outer membrane in epithelial cells.

Scanning Electron Microscopy: 3D SEM Metrology for 10 nm Structures

PML researchers have devised an idea for determining the three-dimensional shape of features as small as 10 nanometers wide. The model-based method compares data from scanning electron microscope (SEM) images with stored entries in a library of three dimensional (3D) shapes to find a match and to determine the shape of the sample. The work provides a powerful new way to characterize nanostructures.

European Molecular Imaging Meeting - EMIM 2014

The European Molecular Imaging Meeting (EMIM 2014) will take place from June 4-6, 2014 in Antwerp, Belgium. Molecular imaging is rapidly moving to multimodality approaches, integrating more and more also microscopic imaging. To acknowledge this trend, the European Society for Molecular Imaging (ESMI) strives to integrate the themes of in vivo and molecular microscopy into existing activities of molecular imaging.

3D X-Ray Film: Rapid Movements in Real Time

How does the hip joint of a crawling weevil move? A technique to record 3D X-ray films showing the internal movement dynamics in a spatially precise manner and, at the same time, in the temporal dimension has now been developed by researchers at ANKA, KIT's Synchrotron Radiation Source. The scientists applied this technique to a living weevil. From up to 100,000 two-dimensional radiographs per second, they generated complete 3D film sequences in real time or slow motion. The results are now published in the Proceedings of the National Academy of Sciences (PNAS).
