experiments

The Jülich Centre for Neutron Science JCNS operates instruments at the national and international leading sources FRM II, ILL and SNS under a common scientific objective. JCNS provides external users with access to world class instruments under standardized conditions at the neutron source best suited for their respective experiments. This film about JCNS was commisioned by Forschungszentrum Jülich GmbH and produced by TRICKLABOR. For full credits and production notes please visit...

In this short video created for the Kavli Science Video Contest, I explain the reason why I think science is cool...because of the science experiments! I demonstrate a few interesting experiments and briefly explain the cool science behind the Diet Coke and Mentos experiment! I hope you enjoy the video, thanks for watching! -Nicholas

Science experiment, kids experiment with gravity while creating a pop bottle racer.

In the third part, I discuss how the complex shapes of cells are created by the cytoskeleton, and I compare and contrast prokaryotes (which have actin-, tubulin-, and intermediate filament -like proteins) and eukaryotes in this regard. In particular, I speculate that cytoskeletal dynamics were necessary to evolve simple bacterial shapes and cell division, but that additional layers of complexity (namely regulated nucleation and molecular motors) allowed eukaryotes to evolve more complex...

The second part is devoted to understanding how the polymerization of actin can produce, which is a current area of research in our laboratory. Here, I cover theories for how polymerization might be used to produce forces, and our efforts to test these models using optical traps, atomic force microscopes, and nanofabricated devices.

Hal Pashler talks about the correlation between the time periods elapsed between review of information (study gaps) and the time frame for retaining that information, as well as the implications of this study in education.
