  • Trees That Breathe at Night: The Secret Schedule of Clusia

    Trees That Breathe at Night: The Secret Schedule of Clusia
    2026/09/28
    Some tropical trees close their leaf pores all day and breathe after dark. A new genomic look at Clusia—the only tree genus known to use this water-saving schedule—shows that one ancient genome duplication was later edited into three living strategies: all-night CAM, a drought switch, and a hybrid.

  • Zero Crossovers: The Brazilian Sedge That Broke Meiosis

    Zero Crossovers: The Brazilian Sedge That Broke Meiosis
    2026/09/24
    A plain-looking wetland sedge in Brazil makes pollen, fertilizes eggs, and sets seed—then produces daughters that are genetic copies of the mother.

    New genome and cell work shows it has dropped the chromosomal shuffle that sex is supposed to require. The episode walks through two-chromosome meiosis, failed pairing, selfish DNA, and why a flower is not a promise of new combinations.

  • The Marsh Plant That Could Transform Salty Farmland

    The Marsh Plant That Could Transform Salty Farmland
    2026/09/21
    A salt-marsh succulent just got one of the most complete genetic portraits in its family. Six Salicornia genomes and hundreds of wild plants reveal how sea asparagus lives where ordinary crops die—and why salt tolerance looks less like a single switch than a whole botanical network.

  • 18 New Rainforest Trees Named This Week—And They Were Never Missing

    18 New Rainforest Trees Named This Week—And They Were Never Missing
    2026/09/17
    Eighteen rainforest trees just received scientific names. From the Chocó to Andean cloud forest, a decades-long revision of Matisia and Quararibea shows the wet Neotropics are still unfinished business—and that a name can change what we are willing to protect.

  • Trees That Breathe at Night: The Clusia CAM Mystery

    Trees That Breathe at Night: The Clusia CAM Mystery
    2026/09/14
    Some tropical trees close their pores at noon and drink carbon after dark. New Clusia genomes show that this night-shift photosynthesis is not one invention but several drafts written after ancient genome doublings—strong, stress-only, and mixed versions in close relatives.

    A quiet leaf Humboldt could not explain becomes a map of how plants bargain with heat and thirst.

  • Galápagos Snapdragon Returns From Near Extinction

    Galápagos Snapdragon Returns From Near Extinction
    2026/09/09
    A Galápagos snapdragon survived for decades mainly as a pressed specimen. Then people walked the lava, grew shrubs in nurseries, and watched a handful of wild seedlings appear in the rock.

    This episode follows a slow, unfinished return: six plants at the edge, a cove revisited after sixty years, and a next generation that still has to outlast drought.

  • The Devil Flower of Thailand: A Plant That Quit the Sun

    The Devil Flower of Thailand: A Plant That Quit the Sun
    2026/09/07
    A black, horned flower has been formally named from a Thai national-park floor — a plant with no leaves, no chlorophyll, and a life spent mostly underground.

    This episode follows the new species Thismia daemona: how botanists found it in the “wrong” forest, why it feeds through fungi instead of sunlight, and why a population smaller than a football pitch now sits at the edge of disappearing.

  • Why Mosses and Liverworts Matter More Than Trees After Mining

    Why Mosses and Liverworts Matter More Than Trees After Mining
    2026/09/03
    Tiny plants on wrecked ground. This episode follows a quiet finding: mosses and liverworts may be the first engineers on coal waste heaps, holding water, slowing erosion, and opening the door for whatever comes next. Look down.
