Instead of screaming on stage, nine singers from death metal bands are howling in front of University of Utah scientists who are studying the biomechanics of their vocalizations. The participants undergo testing, including MRIs and endoscopies, so researchers can examine their vocal tracts. They have already recorded some surprising results: when one singer screamed, his larynx "dramatically swung to the side," creating a "contortion" the scientists had never seen before, Science Friday said.

For six months, an Australian radio station broadcast a daily show using an AI-generated host — without telling listeners she was not real. The truth about "Workdays with Thy," a weekday music show, only came out when people began to notice that Thy's voice sounded identical when saying the words "old school" on different shows. Thy's voice and likeness were modeled after an employee in the financial department of ARN Media, the station's owner.
