Right now, our natural rubber comes from just one tree species: Hevea brasiliensis. It’s great at producing latex that becomes rubber, but it’s vulnerable to disease and climate shifts. So researchers are looking into a desert shrub that’s native to North America: guayule.

The ocean depths are vast and dark. But there are hotspots on the ocean floor — underwater volcanoes and hydrothermal vents — where lively microbial communities thrive, and even support entire ecosystems. Hear from researchers Anna-Louise Reysenbach, Emily St. John, Gilberto Flores, and Peter Girguis about sampling these communities, and understanding how they’ve adapted to this extreme environment.

In our warming world, we’ll need corn, sorghum and other crops to grow well in worse conditions: with more heat, less water and less fertilizer. Grasses do better in these conditions, so plant biologists James Schnable, Guangchao Sun and Vladimir Torrres have looked into traits that could transfer from grasses into other crops. One grass they studied just happened to be the same species that covered World Cup pitches in 2022.
