Scientists have analyzed the complexity of the songs of the humpback whale. It’s quite advanced, they found! I’m sure you already know of the corresponding analysis of human songs, as demonstrated in Donald Knuth’s seminal paper.
Researchers have been able to measure the gravitational equivalent of a magnetic field, called a "gravitomagnetic field". Not that I understand what this really means, but they believe that their results are in contradiction with Einstein’s general relativity, and could be useful for unifying that and quantum mechanics. Cool!
