Why Is Science Cool? - Science Experiments

submitted by: SpudNicStudios

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!

Cell Organization & Cell Motility: Part 3: Principles of Cellular Organization: The Universal Cytoskeleton (29:17)

submitted by: scivee-team
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...

Cell Organization & Cell Motility: Part 2: Force Generation by Actin Assembly: Theories and Experiments (46:16)

submitted by: scivee-team

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.

Talk by Hal Pashler

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.
