On this week’s show: Portable MRI scanners could revolutionize medical imaging, and pheromones offer a way to control flies that spread disease First up this week: shrinking MRI machines. Staff Writer Adrian Cho talks with host Sarah Crespi about how engineers and physicists are teaming up to make MRI machines smaller and cheaper. Next up on the show, the smell of tsetse fly love. Producer Kevin McLean talks with Shimaa Ebrahim, a postdoctoral researcher in the department of molecular, cellular, and developmental biology at Yale University, about understanding how tsetse flies use odors to attract one another and how this can be used to prevent the flies from transmitting diseases such as African sleeping sickness.
