A Columbia University-led team of astrophysicists has discovered a dozen black holes gathered around Sagittarius A* (Sgr A*), the supermassive black hole in the center of the Milky Way Galaxy.
Andrés Bendesky argues that deciphering the astounding diversity of animal behaviors will help to gain insight into ourselves. In appreciation of this work, he is now being recognized as one of the most promising early-career scientists in America.
