For much of history, tree canopies were pretty much completely ignored by science. It was as if researchers said collectively, "It's just going to be empty up there, and we've got our hands full studying the trees down here! So why bother?" But then around the mid-1980s, a few ecologists around the world got curious and started making their way up into the treetops using any means necessary (ropes, cranes, hot air dirigibles) to document all they could find. It didn't take long for them to realize not only was the forest canopy not empty, it was absolutely filled to the brim with life. You've heard of treehouses? How about tree gardens?!  This week, we bring you a story we first released in 2022. We journey up into the sky and discover forests above the forest. We learn about the secret powers of these sky gardens from ecologist Korena Mafune, and we follow Nalini Nadkarni as she makes a ground-breaking discovery that changes how we understand what trees are capable of.  P.S. This episode is a layer cake of arboreal surprises (including the reappearance of a certain retired host.  LATERAL CUTS:From Tree to Shining Tree (https://zpr.io/4cHtDdYTuNxT): The episode that started this journey, where we look down instead of up.

We first learned about the magical world of the canopy from this beautiful video. It features Korena Mafune’s research up in the treetops, as well as the people who have dedicated their lives to saving what’s left of the old growth forests.

To the eye alone, Spica is one of the 15 brightest stars in the night sky. And it really is brilliant. At visible wavelengths, it’s about 2,000 times brighter than the Sun. It looks white with a hint of blue. When you look at Spica with special instruments, though, it’s even more impressive. It consists of two stars, not one. Both are much bigger and heavier than the Sun. And when you add up all wavelengths of light, they shine about 20 thousand times brighter than the Sun. Most of that energy is in the ultraviolet – wavelengths that are too short for the human eye. Spica’s two stars produce so much of it because their surfaces are tens of thousands of degrees hotter than the Sun’s. In fact, the type of energy a star emits depends almost entirely on its surface temperature. And so does the star’s color. To the eye alone, the hottest stars look blue. But they emit huge amounts of ultraviolet. The coolest stars look orange or red. They emit huge amounts of infrared light – wavelengths that are too long for the human eye. Stars in the middle are white or yellow. They emit most of their light at visible wavelengths. So with a star like the Sun, we see most of the energy it produces – light that’s just right for the human eye. Spica is quite close to the Moon as darkness falls this evening. The Moon will slide away from the star during the night, but they’ll still be close as they set, around dawn. Script by Damond Benningfield

He teaches them the basics of card-counting, the technique that gives players an advantage against the house — enough of an advantage that most casinos will ask you to leave if they catch you doing it. (9 minutes)Act One: Jack Hitt tells the story of the Christian card-counting team featured in the documentary Holy Rollers, and why they see no contradiction in being devout Christians who spend their days in casinos. (18 minutes)Act 2: Ira and Robyn go to the casino to try out their newfound card-counting skills. (5 minutes)Act Two: Producer Sarah Koenig tells the story of a woman who sued the casino where she lost her inheritance, saying that it was to blame, not her.
