Marketplace: Smartphone apps are now being used by researchers as a mechanism for collecting large amounts of data. With Project Budburst, for example, nature lovers can help scientists monitor plants through the seasons by taking photos of them. The app records the exact locations and observation times and can even allow the user to add notes. With some 13 000 participants, Project Budburst adds significantly to the amount of ecological data available to researchers. In a Marketplace audio file, Liyna Anwar interviews UCLA student Sophie Gerrick about her contributions as a citizen scientist.
