Low Temperature Limits for Motility in Arctic Ice Diatoms
Overview: Arctic ice diatoms and ice gliding In the harsh Arctic environment, ice-dwelling diatoms endure extreme cold, variable brine pockets, and constrained liquid pathways within the ice. Our study provides direct cellular observations of these microorganisms embedded in ice and reveals a previously undocumented ice-gliding ability that helps them navigate the ice matrix to reach…

Critique of Polar Geoengineering Ideas: Scientists Weigh In
Understanding Polar Geoengineering Proposals In the quest to combat climate change, some unconventional proposals have emerged, particularly in the context of polar geoengineering. Notable among these are the ideas of giant underwater curtains and the scattering of reflective glass beads across ice sheets. While these proposals aim to mitigate the impacts of the climate crisis,…
