A computer system that automatically tracks the movements of proteins within a living cell has been developed by a team of biologists and computer vision experts. It could save researchers the hours often spent analysing microscope images by hand, to determine the way a cell works. The system, called CellTracker, automatically analyses a series of still digital images captured through a microscope. Doug Kell at Manchester University in UK, the lead biologist involved with the project, believes the system could dramatically speed up studies of cells' function. "Most people just fix cells [in one place], which kills their metabolism," he...
