Brennan Lee Mulligan is a professional dungeon master, playing Dungeons and Dragons (D&D), a popular tabletop role-playing game, for audiences online and in person. In January his D&D show on Dropout.tv, Dimension 20, played a live game at Madison Square Garden in New York City. The show—and the game—experienced a resurgence during the COVID pandemic. Now researchers are diving into D&D science, showing how the game and the togetherness it creates can benefit mental health. Rachel Feltman chats with Lee Mulligan about the success of Dimension 20 and the psychological and cultural need the game may serve for its players.

Come with Science Quickly on a field trip to the Laser Interferometer Gravitational-Wave Observatory (LIGO) Lab at the Massachusetts Institute of Technology. Host Rachel Feltman is joined by Matthew Evans, MIT’s MathWorks professor of physics, to talk about the last 10 years of gravitational-wave research. Gravitational waves were discovered in 2015 by the LIGO team. Since then, innovations from the LIGO Lab have changed our understanding of the universe and made major shifts across physics. Now they’re preparing for the next generation of gravitational-wave detectors.

Each year more than half a million people undergo bariatric surgery, a procedure geared toward weight loss. But research shows that stigma around weight can continue to affect people’s lives even during recovery from the procedure. 

Larissa McGarrity is a clinical associate professor at the Spencer Fox Eccles School of Medicine at the University of Utah and lead psychologist at the school’s comprehensive Weight Management Program. She and her colleagues assessed 148 people who received bariatric surgery before their procedure and one and a half and three years after to learn more about their physical, mental and emotional health over the recovery period.

Last year Science Quickly looked across disciplines to piece apart the science of singing. To understand why humans sing, musicologists collaborated on an international study of folk music. To understand how we sing, neuroscientists differentiated how our brain processes speech and singing. Music enthusiast and associate mind and brain editor Allison Parshall takes us through some hallmark 2024 studies that, taken together, piece together the evolutionary origins of singing.
