The location of the FRB 150807. The yellow circle shows the typical location of an FRB. There are thousands of stars and galaxies in this direction. Because FRB 150807 was very bright the astronomers were able to locate it to a small region near the edge of that circle, shown as the pink banana-shaped region in the inset. In this region there are only six detected galaxies. The position of the most likely host galaxy, VHS7, is highlighted on the plot.

Discovery and screening of the humimycins. Top: the humimycins were predicted from closely related gene clusters found in two Rhodococcus spp. cultured from human subjects. Center: chemical structures of humimycin A and B; the two antibiotics differ only at the fourth (F or Y) and sixth (V or I) residues. Bottom: MIC values for the humimycins against a panel of human commensal and pathogenic bacteria; the humimycins were particularly active against bacteria in the Staphylococcus and Streptococcus genus.
