  • Salt Stress Impacts Photosynthesis in Algae

    Salt Stress Impacts Photosynthesis in Algae

    Data Points

    Scientists investigated how salt affects the photosynthetic electron transport chain in freshwater green alga.

  • Role of p53 in the Cell Cycle

    Role of p53 in the Cell Cycle

    Data Points

    Researchers investigated the role of p53 in cell cycle regulation by genetically engineering a cell line with deleted copies of the p53 gene. They exposed the cell lines to DNA-damaging radiation and observed how this exposure impacted mitosis.

  • Identifying the Key Genes for Regeneration

    Identifying the Key Genes for Regeneration

    Scientists at Work

    (9 min 55 sec) Planarians have an amazing ability to regenerate lost tissues. In this video, scientists knock out two different genes in planaria to start to understand how the process works—and they generate animals with two heads and two tails!

  • Cell Division and Cancer Risk

    Cell Division and Cancer Risk

    Data Points

    Cancer is typically attributed to hereditary and environmental factors, but these only explain a fraction of overall cancer risk. In this study, researchers investigated how a third factor—chance genetic mutations that occur during stem cell division—may contribute to the overall rate of cancer incidence in different body tissues.

  • Efficacy of a Treatment for Chronic Myeloid Leukemia

    Efficacy of a Treatment for Chronic Myeloid Leukemia

    Data Points

    Dr. Brian Druker and colleagues monitored white blood cell counts in six patients with chronic myeloid leukemia treated with the drug, STI571, which blocks the activity of the cancer-causing tyrosine kinase BCR-ABL.

  • Animated Life: Seeing the Invisible

    Animated Life: Seeing the Invisible

    Animated Shorts

    (6 min 31 sec) This animated feature celebrates 17th-century citizen-scientist Antonie van Leeuwenhoek, whose discoveries of microbes changed our view of the biological world. Also available in Spanish.

  • DNA Sequence Technology Improves Cancer Treatment

    DNA Sequence Technology Improves Cancer Treatment

    Clips

    (2 min 6 sec) Dr. Charles Sawyers discusses how the identification of most cancer genes could transform cancer into a chronic disease.

  • Somatic Cell Nuclear Transfer Video

    Somatic Cell Nuclear Transfer Video

    Clips

    (2 min) Somatic cell nuclear transfer (SCNT) is performed looking through a microscope and using small glass pipettes to handle human eggs and to remove and transfer nuclei from one cell to another.

  • Somatic Cell Nuclear Transfer Animation

    Somatic Cell Nuclear Transfer Animation

    Animations

    (52 sec) Somatic cell nuclear transfer (SCNT) is a technique for cloning. The nucleus is removed from a healthy egg. This egg becomes the host for a nucleus that is transplanted from another cell, such as a skin cell. The resulting embryo can be used to generate embryonic stem cells with a genetic match to the nucleus donor (therapeutic cloning), or can be implanted into a surrogate mother to create a cloned individual, such as Dolly the sheep (reproductive cloning).

  • Using p53 to Fight Cancer

    Using p53 to Fight Cancer

    Animations

    (1 min 2 sec) This animation demonstrates how cancerous cells could be destroyed using a modified virus.
