Raw images of the manuscript entitle: "Detecting life by behavior, the overlooked sensitivity of behavioral assays" Description: Using a magnetotactic bacterial species, Magnetospirillum magneticum, we conduct a lab sensitivity experiment comparing PCR with the hanging drop behavioral assay, using a dilution series. Data: 1.-Gel image resulted from the Magnetospirillum magneticum PCR assays. 2.-Microphotographs of Magnetospirillum magneticum obtained using the hanging drop technique and serial dilution. 3.-Videos 1 to 4.Environmental samples were taken from Agmon Hula lake, (33° 10′ N 35° 60′ E). We used the HDT (see main MS) to morphologically identify magnetotactic bacterial species.
