Today marks the summer solstice, the astronomical start of summer. But parts of the country have already been enduring summer-like temperatures. Alaskan meteorologists at the National Weather Service have had to issue their first-ever heat advisory this week, with temperatures in central Alaska entering the mid-80s. Host Ira Flatow talks with Vox reporter Umair Irfan about the changing Alaskan climate, plus how shifting climates could affect world crop staples, new developments in the 23andMe bankruptcy, a new technique to see around corners, the upcoming unveiling of the first images from the Vera Rubin Observatory in Chile, a stunning view of the galaxy Sculptor, and the tale of a 135-year old tortoise father.
