Astronomers have found an unlikely object in an improbable place: a monster black hole lurking inside one of the tiniest galaxies known. The dwarf galaxy containing the black hole is the densest galaxy ever seen, cramming 140 million stars within a diameter of about 300 light-years (just 1/500th of our Milky Way galaxy's diameter). However, the black hole inside the galaxy is five times the mass of the black hole at the center of our Milky Way. This suggests that the dwarf galaxy may actually be the stripped remnant of a larger galaxy that was torn apart during a close encounter with a more massive galaxy. The finding implies that there are many other compact galaxies in the universe that contain supermassive black holes.
The push to encourage women to enter STEM fields has become so ubiquitous that there are op-eds written seemingly every week, a dedicated page on the White House website, and even a line of interactive dolls. A lesser-known gender discrepancy in science, however, is the lack of female research subjects. Despite a 1993 law requiring women and minorities to be included as subjects in clinical research funded by the National Institutes of Health, women continue to be under-represented.
Of course, clinical trials (testing medical interventions on human subjects) are only a small subset of medical...
