Black hole 'family portrait' is most detailed to date

An international research collaboration including Northwestern University astronomers has produced the most detailed family portrait of black holes to date, offering new clues as to how black holes form. An intense analysis of the most recent gravitational-wave data available led to the rich portrait as well as multiple tests of Einstein's theory of general relativity. (The theory passed each test.)

Male fin whales surprise scientists by swapping songs

Until now, scientists believed the male fin whale sings just one song pattern, which is unique to the males in his particular group—but new research has blown this theory out of the water. The study, published in Frontiers in Marine Science, suggests that these endangered deep-sea giants actually sing multiple different songs, which may spread to different parts of the ocean through migrating individuals. Understanding the complexity of fin whale song provides new insights into how their populations move and change over time, helping efforts to better protect and manage the world's second largest mammal.
