• Why Alaska’s salmon streams are suddenly bleeding orange
  Warming Arctic permafrost is unlocking toxic metals, turning Alaska’s once-clear rivers into orange, acid-laced streams. The shift, eerily similar to mine pollution but entirely natural, threatens fish, ecosystems, and communities that depend on them—with no way to stop the process once it starts.
• Soil warming experiments challenge assumptions about climate change
  Heating alone won’t drive soil microbes to release more carbon dioxide — they need added carbon and nutrients to thrive. This finding challenges assumptions about how climate warming influences soil emissions.
• Scientists just found the “master switch” for plant growth
  Scientists at Cold Spring Harbor Laboratory have cracked open the secrets of plant stem cells, mapping key genetic regulators in maize and Arabidopsis. By using single-cell RNA sequencing, they created a gene expression atlas that identifies rare stem cell regulators, links them to crop size and productivity, and offers a new roadmap for breeding resilient, […]
