Researchers found that a symbiont capable of fixing nitrogen (turning it into a biologically usable form) has evolved into an organelle—an intrinsic part of the algae cells that host it. The discovery is of great interest for understanding organelle genesis and for efforts to engineer agricultural plants with built-in nitrogen-fixing capabilities. Read more »
Pacific Kelp Forests Are Far Older than We Thought
Researchers scanned newly discovered kelp fossils using x-ray tomography at the ALS. The images provided morphological information about the ancient kelp and, along with isotopic analyses, provided insights into the evolutionary history of northeastern Pacific Ocean kelp forests, which flourished more than 32 million years ago.

New Insights Lead to Better Next-Gen Solar Cells
Perovskites show great promise to reduce the costs of solar power but are not yet durable enough to be commercially viable. Researchers used simultaneous characterization techniques to understand why a simplified fabrication process works so well, providing key insights to nudge perovskites closer to commercialization.
