    Counting the Rings

    Image of the Week

    An otolith from a lanternfish (Gymnoscopelus nicholsi) is used to estimate the fish’s age and growth rate.

  • Cell Division and Cancer Risk

    Cell Division and Cancer Risk

    Data Point

    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.
