Soil microbes consume 80% of atmospheric hydrogen - but will they adapt fast enough to handle leaks from tomorrow's hydrogen infrastructure? Check out this coverage of our NSF research project aimed at addressing this question with new data-model efforts: cales.arizona.edu/news/u-led-r...

Volatile Organic Compound (VOC) Exchange in Tropical Leaf Litter in Response to Wetting: An Automated Scheme to Classify Flux Pulse Dynamics
Wetting of decomposing leaf litter triggered the emission and uptake of 121 potential VOCs including methanol, acetaldehyde, and acetone Most VOCs appear to originate from plant processes, althou...

We are hosting a PhD course on volatiles in ecosystems for 30 international PhD students. Today we heard flash talks by all participants, got an introduction to isotopes, a lab tour and a tour in the Botanical Garden of #SNM. We are thankful for Faculty of Science @ucph.bsky.social for funding.

Has anyone else used Qiagen's PowerProtect solution (now that LifeGuard is unavailable) but with success extracting DNA/RNA from soil samples?
