One day in the lab, we accidentally discovered that the spines of a cactus 🌵 straighten when exposed to fog. I was intrigued and so were my collaborators. How does this work and what can be gained from it? Here are some of the answers in our new preprint: doi.org/10.1101/2025...

Mapping the roots of saguaros at Saguaro NP. The DBG is partnering with SNP and the U of Wyoming to map the roots of saguaros. Knowing the distribution of saguaro roots reveals how sensitive they are to droughts, and to what extent these iconic plants engineer the water cycle of desert ecosystems.

Monarch butterflies could get more government protection. Why it matters for Arizona

Monarch butterflies, found throughout Arizona, could become one of the next species listed under the Endangered Species Act.
