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.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
