  • The Virus Hunter's Toolkit

    The Virus Hunter's Toolkit


    (58 min 33 sec) New technologies like the Virochip harness DNA's properties to identify and fight new viruses.

  • Interview with Katherine Sorber

    Interview with Katherine Sorber


    (4 min 24 sec) Katherine Sorber, a graduate student in the DeRisi lab, describes her research on malaria.

  • Leading-Edge Bioinformatics

    Leading-Edge Bioinformatics


    (6 min 36 sec) Peter Skewes-Cox, and Dr. Graham Ruby, both in the DeRisi lab, explain state-of-the-art DNA sequencing and bioinformatic technologies.

  • Exploring Obesity: From the Depths of the Brain to the Far Pacific

    Exploring Obesity: From the Depths of the Brain to the Far Pacific


    (58 min 29 sec) Dr. Friedman shows how leptin rewires neural circuits, and how population studies may identify obesity genes.

  • Bioethics Discussion

    Bioethics Discussion


    (39 min 44 sec) Genetic research benefits health, but also raises thorny ethical issues.

  • Shotgun sequencing

    Shotgun sequencing


    (1 min) In shotgun sequencing many copies of the entire genome are "blown up" into millions of small fragments. Each small fragment is sequenced. Powerful computers then assemble the individual fragments into the original configuration. Repeat sequences pose a problem for this approach because their sizes can be much larger than the small fragments.

  • Human genome sequencing

    Human genome sequencing


    (1 min 49 sec) The public Human Genome Project started by identifying unique marker sequences distributed throughout the genome. Then, many copies of a small section of DNA were randomly cleaved into smaller fragments, and each small fragment was sequenced. Because there were originally many copies of the DNA in question, many fragments represented the same part of the genome. These were aligned by identifying overlapping regions of the sequence, and then they were assembled into the original DNA.

  • Using DNA to Trace Human Migration

    Using DNA to Trace Human Migration

    Click & Learn

    All living humans originated from populations of ancestors who migrated out of Africa less than 100,000 years ago. Learn how scientists have used genetic markers to trace the migration routes and origins of modern human populations.

  • How to Analyze DNA Microarray Data

    How to Analyze DNA Microarray Data

    Click & Learn

    DNA microarrays, or gene chips, are an important new technology for genomic research. Learn how researchers use computing to analyze and interpret the huge datasets generated by microarray experiments.

  • Microarray Manufacturing Technology

    Microarray Manufacturing Technology

    Click & Learn

    How both gene chips and microarray slides are created.

  • Discussion Session: Teacher discussion

    Discussion Session: Teacher discussion


    (43 min 24 sec) A wide-ranging 45-minute discussion between Dr. Eric Lander, Dr. Stuart Schreiber, and four Washington DC-area high school teachers.

  • Chemical Genomics: New Tools for Medicine

    Chemical Genomics: New Tools for Medicine


    (58 min 29 sec) Scientists now have the ability to create millions of new molecules. How do they test whether any of these molecules are useful?

  • Human Genomics: A New Guide for Medicine

    Human Genomics: A New Guide for Medicine


    (58 min 35 sec) Dr. Lander explores human genetic variation and how it may affect individual susceptibility to certain diseases.

  • Probing Genes and Genomes

    Probing Genes and Genomes


    (58 min) To understand life's processes, perturb them. How a process responds to an insult can provide clues about normal function or mimic a specific disease state.

  • Reading Genes and Genomes

    Reading Genes and Genomes


    (58 min 9 sec) Dr. Eric Lander takes us on a tour of this remarkable genetic century, describing the rapid advances in DNA sequencing technologies and information science.

  • Scanning Life's Matrix: Genes, Proteins, and Small Molecules

    Scanning Life's Matrix: Genes, Proteins, and Small Molecules


    In four presentations, Stuart L. Schreiber, PhD, and Eric S. Lander, PhD, open a window onto the fast-paced world of genomic science and chemical genetics.

  • Microarrayer In Action

    Microarrayer In Action


    (2 min) How a microarraying robot delivers hundreds of small molecules to a series of slides.

  • Gene Chip Manufacturing

    Gene Chip Manufacturing


    (1 min 57 sec) Gene chips, also called DNA microarrays, have a broad range of applications in current research, including enabling researchers to measure the activity of thousands of genes simultaneously. Dr. Eric Lander describes the process used to manufacture gene chips.

  • Molecular Screening

    Molecular Screening


    (38 sec) After a chemical biologist has made many novel small molecules by diversity-oriented synthesis, the next step is to find those that are useful. Molecules need to be "screened." Conceptually, screening is like using proteins as a custom filter to catch potentially useful small molecules.

  • The Microbes Strike Back

    The Microbes Strike Back


    (58 min 35 sec) Dr. Brett Finlay explains why bacterial diseases continue to be a major health problem worldwide, causing a third of the world's deaths every year.
