This activity explores images of the bobtail squid, which serve as phenomena for learning about symbiosis and interspecies interactions.

This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.

This animation shows how genes associated with autism affect the structure and function of neuronal synapses.

In this talk, biomedical scientist Charles Sawyers discusses how genetic data reveal common mutations in cancer and can help uncover shared genetic mechanisms among different cancer types.

This animation shows how the cancer treatment Gleevec inhibits the cancer-causing protein BCR-ABL.

This tutorial describes how bacteria communicate by a process known as quorum sensing, as shown through a series of experiments involving genetically engineered bioluminescent bacteria.

This tutorial describes the symbiosis between the Hawaiian bobtail squid and bioluminescent bacteria.

This video provides a demonstration of bioluminescent bacteria glowing in the dark.

This animation explores the LUX operon, a set of five genes that are involved in bacterial bioluminescence.

This animation shows how the drug Prialt suppresses signals from the nervous system, which can paralyze certain organisms.

This animation shows how cone snail toxins cause paralysis by blocking signal transmission at the synapse between neuron and muscle.

This tutorial describes how neurons generate action potentials, and how scientists measure neuronal activity and record the firing of individual neurons.
