  The tilcayo, cancer-sniffing dogs, and 8 more things going right

  Sep 25, 202626 min

  There's a startup training dogs to detect cancer across seven types… and there's over 90 percent accuracy across six hospitals. This week Arielle and Karissa also cover a wildcat species science just got around to naming (local communities already had a name for it), bison reshaping a Mexican desert faster than anyone expected, and what Cambridge researchers found when they actually quantified how reading protects your brain.

  A 450-year map mistake gets corrected by 164 countries, plus nine more solutions

  Sep 18, 202623 min

  Most world maps show Greenland and Africa as roughly the same size… which is kind of unbelievable considering Africa is 14 times larger! This error has been built into classrooms, boardrooms, and institutions since 1569. Last week, 164 countries finally voted to fix it. Arielle and Karissa also cover a solar ambulance built by university students that completed its first real-world test in rural Kenya, a student baking operation in Frisco, Texas that has raised over $8,000 for food-insecure kids, and why the best time to deal with weeds is probably right now.

  NYC bans AI for 500,000 students, and seven other solutions

  Sep 11, 202622 min

  An approach to treating degenerative blindness has been in development for more than ten years across research institutions in Spain. The result is not a surgery, a gene therapy, or an implant. It is eye drops. Light-activated compounds that restored vision in blind animal models by stepping in where lost photoreceptors used to be, without disturbing the underlying disease. Arielle and Karissa cover eight solutions this week, including the country's broadest AI ban for over half a million students, a urine test that spots bladder cancer with 92% accuracy, and what steel wind turbine foundations are inadvertently doing for marine life around Long Island.

  The Optimist Daily's Weekly Roundup

  AI music banned from Australia's charts, Roman telescope launches, a biodegradable balloon and much more!

  Sep 4, 202627 min

  Arielle and Karissa are reunited after a few weeks apart, covering a wide range of solutions this episode: a new telescope that survived two White House cancellation attempts, the decade-long trial that settles the statin-and-dementia debate once and for all, and a biodegradable balloon that took three years and hundreds of failed experiments to get right.
