Boom! Detecting Gregarious Goliath Groupers Using Their Low-frequency Pulse Sounds

From growls to booms, whales, fish and crustaceans all produce sounds. Selecting the gregarious Goliath grouper, researchers deployed a novel automated detector and localization model to find underwater marine organisms using their low-frequency pulse sounds.

36 Dwarf Galaxies Had Simultaneous “Baby Boom” of New Stars

Three dozen dwarf galaxies far from each other had a simultaneous “baby boom” of new stars, an unexpected discovery that challenges current theories on how galaxies grow and may enhance our understanding of the universe. Galaxies more than 1 million light-years apart should have completely independent lives in terms of when they give birth to new stars. But galaxies separated by up to 13 million light-years slowed down and then simultaneously accelerated their birth rate of stars, according to a Rutgers-led study published in the Astrophysical Journal.
