This video from the Howard Hughes Medical Institute is from the 2007 Holiday Lectures on Science: "AIDS: Evolution of an Epidemic." Bisola O. Ojikutu, M.D., M.P.H. discusses antiretroviral therapy in AIDS and HIV. The video is available as an indexed video with synchronized slides or webcast video only. Both require RealPlayer. The video is 58 minutes and 31 seconds long and there are 91 slides.
How a cell infected by a virus signals cytotoxic T lymphocytes to kill the cell before the virus replicates and spreads. This video is two minutes and 34 seconds in length, and available in Quick Time (11 MB) and Windows Media Player (23 MB).

A mini-documentary discussing the remarkable regenerative capabilities of the planarian, and how HHMI researcher Alejandro Snchez Alvarado uses them to study the biology of stem cells. This presentation is also featured on the DVD Potent Biology: Stem Cells, Cloning, and Regeneration, available for free from HHMI. This video is 11 minutes and 46 seconds in length, and available for download in Quicktime (114 MB) and Windows Media (156 MB) formats.

When two different strains of influenza infect a single cell, their genetic material can mix freely, resulting in a new third strain of influenza.
This lecture goes through genetic basis for diversity and the human genome project.
This lecture covers the concept of networks of proteins as well as using genomics to investigate glucose sensing and type II diabetes. Also provides an overview of the Chembank project, linking chemistry, biology and medicine.
This lecture covers the basics of understanding obesity from the definition of the condition and quantifying it through BMI, as well as information about the chemical that is responsible for obesity, Leptin.
This lecture provides information about the cells responsible for hearing (hair cells), how the internal ear works, the physiological results of this process, the current work in this field, and information about deafness.
Delivering a single virus to a cell allows the virus to infect the cell, replicate, and give rise to many progeny viruses. These viruses can then infect many neighboring cells.
Record electrical activities of individual neurons while you deliver mechanical stimulus to the attached skin. Inject fluorescent dyes into the neurons to visualize their morphology. Identify the neurons based on the morphology and the response to stimuli, comparing them to previously published results.
