Compositional Heterogeneity Structures Microbial Microhabitats across Distinct Mineral Substrates

Federica Calabrese, Peter Schroedl, Nathan Hadland, Jason Yu et autres

Abstract Microbial communities living on and in rocks operate at the microscale, where interactions with minerals fundamentally shape community structure and function. Yet the relationship between micron scale mineralogical configurations and microbial distributions remains poorly understood. We tested the hypothesis that microbial …

Dual-BONCAT reveals distinct subpopulations of anabolically active cells

Dylan Mankel, Yasheng Maierhaba, Claire Momjian, Federica Calabrese et autres

ABSTRACT Bio-orthogonal non-canonical amino acid tagging (BONCAT) has emerged as a prominent molecular technique that enables microbial ecologists to visualize and identify metabolically active cells in cultures and complex microbial communities. To date, researchers have used just one non-canonical amino acid (ncAA) …

Evidence of dark oxygen production at the abyssal seafloor

Andrew K. Sweetman, Alycia J. Smith, Daniëlle de Jonge, Tobias Hahn et autres

Deep-seafloor organisms consume oxygen, which can be measured by in situ benthic chamber experiments. Here we report such experiments at the polymetallic nodule-covered abyssal seafloor in the Pacific Ocean in which oxygen increased over two days to more than three times the …

Carbonate chimneys at the highly productive point Dume methane seep: Fine‐scale mineralogical, geochemical, and microbiological heterogeneity reflects dynamic and long‐lived methane‐metabolizing habitats

Peter Schroedl, Michael A. Silverstein, Daisy DiGregorio, Clara L. Blättler et autres

Methane is a potent greenhouse gas that enters the marine system in large quantities at seafloor methane seeps. At a newly discovered seep site off the coast of Point Dume, CA, ~ meter-scale carbonate chimneys host microbial communities that exhibit the highest …

Crafting effective oversight for the long-term storage of spent nuclear fuel on sites at risk of climate and coastal hazards

Alexander Brown, Jeffrey J. Marlow, Julie Sorfleet

Despite a documented push to expand nuclear energy in the U.S., the status quo of indefinite in-situ nuclear waste storage is uncertain and increasingly threatened by climate and coastal hazards. Findings from Humboldt Bay, California, one of the nation’s most vulnerable nuclear …

Chapter 6: The Breadth and Limits of Life on Earth

Jennifer L. Thweatt, Chester E. Harman, Maicon Nascimento Araújo, Jeffrey J. Marlow et autres

Scientific ideas about the potential existence of life elsewhere in the universe are predominantly informed by knowledge about life on Earth. Over the past ∼4 billion years, life on Earth has evolved into millions of unique species. Life now inhabits nearly every …
