A biomedical-imaging technique that would highlight the cytoskeletal infrastructure of nerve cells and map the nervous system as it develops and struggles to repair itself has been proposed by biophysics researchers at Cornell and Harvard universities.
Reporting in Proceedings of the National Academy of Sciences (PNAS June 10, 2003) , the researchers say that besides the new imaging technique’s obvious applications in studying the dynamics of nervous system development, it could answer the puzzle about which errant pathways initiate damage to brain cells, a key question about the onset of Alzheimer’s disease.
The PNAS report, "Uniform polarity microtubule assemblies imaged in native brain tissue by second harmonic generation microscopy," is the work of Watt W. Webb, professor of applied physics at Cornell and leader of the research program. His laboratory collaborators in the School of Applied and Engineering Physics are graduate students Daniel A. Dombeck and Harshad D. Vishwasrao and research associate Karl A. Kasischke, M.D. Martin Ingelsson and Bradley T. Hyman of Massachusetts General Hospital, the largest teaching hospital of Harvard Medical School, also are collaborators.

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.
Plug connectors are tiny and, at first glance, unremarkable – yet modern vehicles would be unable to function without them. Several thousand plug connectors...

An international research team with Prof. Cornelia Denz from the Institute of Applied Physics at the University of Münster develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures that can be seen in rainbows or when light is transmitted through drinking glasses.
Modern applications as high resolution microsopy or micro- or nanoscale material processing require customized laser beams that do not change during...
