- Abstract:
Discover what controls how fast tiny molecular motors in our body pull through a single strand of DNA. How hard can the motor pull in a tug of war with the optical tweezers? Discover what helps it pull harder. Do all molecular motors behave the same?

- Abstract:
Did you ever imagine that you can use light to move a microscopic plastic bead? Explore the forces on the bead or slow time to see the interaction with the laser's electric field. Use the optical tweezers to manipulate a single strand of DNA and explore the physics of tiny molecular motors. Can you get the DNA completely straight or stop the molecular motor?

- Abstract:
Learn how simple rule-driven dynamical systems can produce complex dynamical behavior, like 2nd order phase transitions, criticality and clustering. This simulation will guide you through a tutorial that introduces the model incrementally and depicts the computation of the order parameter, critical parameter and critical exponent.

- Abstract:
Explore stretching just a single strand of DNA using optical tweezers or fluid flow. Experiment with the forces involved and measure the relationship between the stretched DNA length and the force required to keep it stretched. Is DNA more like a rope or like a spring?
