... When Horsley tagged the Blimp1 positive cells and tracked them, she found that the daughters of the Blimp1 cells contribute to the entire gland. Also, when grown outside in culture, the cells that make Blimp1 can divide and self-renew, as well as make the cell types important for generating the oils of the ...... labeled these cells with a fluorescent marker and tracked them using advanced software developed by Richard Adams at the University of Cambridge.

Frommer has tracked glucose in cultured mammalian cells, but until now, plant tissues had proven problematic because of interference from the plants' virus defense mechanisms, as well as high background fluorescence in some plants.

During 2005, a USGS-led team tracked a surf scoter from its coastal wintering area in the San Francisco Bay to pinpoint its nest 2000 miles away in the vast northern boreal forest of interior Canada.
