How Death Metal Singers Make Their Extreme Vocalizations

Being able to belt out a tune like Adele or Pavarotti is not just about raw talent. The best singers in the world have to work on their technique—like how to control their breath and develop the stamina to hit note after note for a two-hour concert. But pop stars and opera singers aren’t the only vocalists who have figured out how to harness their voices for maximum impact. Death metal vocalists also train their voices to hit that unique guttural register. And those iconic screams are not as easy to master as they might seem. Vocal scientists at the University of Utah are now bringing death metal singers into the lab to try to understand how they make their extreme vocalizations. What they’re finding is not only insightful for metalheads, but might also help improve treatment for people with some types of vocal injuries. In a conversation from April, Host Flora Lichtman talks with speech pathologist Amanda Stark, and Mark Garrett, vocal coach and lead singer of the band Kardashev. Read the whole story at sciencefriday.com. Guests: Dr. Amanda Stark is a speech pathologist and vocology researcher at the University of Utah in Salt Lake City, Utah. Mark Garett is a vocal coach and the lead singer of Kardashev. He’s based in Phoenix, Arizona. Transcript available at sciencefriday.com. Subscribe to this podcast.

Tangling With Entanglement And Other Big Ideas In Physics

What have we learned in recent years about black holes? Can entangled quantum particles really communicate faster than light? What’s the story behind Schrödinger’s Cat?

Physicist Sean Carroll and Host Ira Flatow tackled those big questions and more at a recent event at WNYC’s Greene Space in New York City. Carroll’s book The Biggest Ideas in the Universe: Space, Time, and Motion is the SciFri Book Club pick for December. Guest: Dr. Sean Carroll is the Homewood Professor of Natural Philosophy at Johns Hopkins University in Baltimore. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

A Neurologist Investigates His Own Musical Hallucinations

Imagine sitting at home and then all of a sudden you hear a men’s choir belting out “The Star Spangled Banner.” You check your phone, computer, radio. Nothing’s playing. You look outside, no one’s there. That’s what happened to neurologist Bruce Dobkin after he received a cochlear implant. He set out to learn everything he could about the condition, called musical hallucinosis. In a story from August, Host Ira Flatow talks with Dobkin about his decision to publish his account in a medical journal and why the condition is more common than he realized. Guest: Dr. Bruce Dobkin is a neurologist at UCLA Health. Transcript is available at sciencefriday.com. Subscribe to this podcast.

Great Program

Ryan A. Rich

Overall, great program! Wouldn't miss a week and it's great that I can now get it as a podcast since I live overseas. Wish they'd stop 'good thing/bad thing' but otherwise, I love the program!
Love the new long form podcast

Long time listener. Great pop science. Highly recommended. 5 stars if they didn't have a blind spot for medical pseudoscience. "Integrative" medicine is quack speak for CAM /alternative medicine. Disappointed those guests are allowed to speak for science.
SCIFRI is good
