About this episode

Jenny Mac shares five uplifting news stories including a record-breaking marathon and health-related discoveries.

Jenny Mac shares five good news stories: a Guinness World Record for the deepest marathon, run 3,669 feet 10 inches underground in a mine by 55 runners from 18 countries over 11 laps in hot, humid, dusty conditions, raising about $1 million for charity; an English woman whose German Shepherd’s unusual sniffing led her to a scan that found a golf-ball-sized stage-one lung tumor that was removed, highlighting how dogs can detect disease-related odor molecules and efforts to build sensor-based alternatives; research suggesting yo-yo dieting can still reduce harmful visceral abdominal fat, based on MRI-tracked participants in two 18-month Mediterranean-style diet trials followed for up to 10 years; Brazilian scientists creating nutrient-rich chocolate-flavored “super honey” by using honey and ultrasonic waves to extract compounds from cocoa husks; and a truck accident that released 40 cows, prompting deputies and animal control to round up all cattle safely after a seven-hour road closure. 5 Good News Stories is a daily podcast with five positive, uplifting news stories to brighten your day.
