Abstract The term “pseudo‐single domain” (PSD) has been used to describe the transitional state in rock magnetism that spans particle size range between single domain (SD) and multidomain (MD) states. for stable SD most commonly occurring terrestrial magnetic mineral, magnetite, is so narrow (~20–75 nm) it widely considered much of paleomagnetic record interest carried by PSD rather than particles. concept has, thus, become dominant explanation magnetization associated with a major fraction...
Terrestrial reactive oxygen species (ROS) may have played a central role in the formation of oxic environments and evolution early life. The abiotic origin ROS on Archean Earth has been heavily studied, are conventionally thought to originated from H2O/CO2 dissociation. Here, we report experiments that lead mineral-based source oxygen, rather than water alone. mechanism involves generation at abraded mineral-water interfaces various geodynamic processes (e.g., currents earthquakes) which...
Previous investigations of the salinity effects on microbial community composition have largely been limited to dynamic estuaries and coastal solar salterns. In this study, mineralogy was studied by using a 900-cm sediment core collected from stable, inland hypersaline lake, Lake Chaka, Tibetan Plateau, north-western China. This core, spanning time 17,000 years, unique in that it possessed an entire range freshwater clays silty sands at bottom gypsum glauberite middle, halite top. Bacterial...
Abstract The evolution of oxygenic photosynthesis is a pivotal event in Earth’s history because the O 2 released fundamentally changed planet’s redox state and facilitated emergence multicellular life. An intriguing hypothesis proposes that hydrogen peroxide (H ) once acted as electron donor prior to photosynthesis, but its abundance during Archean would have been limited. Here, we report previously unrecognized abiotic pathway for H production involves abrasion quartz surfaces subsequent...
ABSTRACT Glycerol dialkyl glycerol tetraethers (GDGTs) found in hot springs reflect the abundance and community structure of Archaea these extreme environments. The relationships between GDGTs, archaeal communities, physical or geochemical variables are underexamined to date when reported often result conflicting interpretations. Here, we examined profiles GDGTs from pure cultures Crenarchaeota terrestrial geothermal representing a wide distribution locations, including Yellowstone National...

Abstract We present results for a series of hysteresis measurements that provide information about remanent, induced, transient‐free, and transient magnetization components. These measurements, differences between measurement types, enable production six types first‐order reversal curve (FORC)‐like diagrams which only double the number involved in conventional FORC measurement. can be used to distinguish magnetic signatures associated with each domain state. When analyzing samples complex...
Abstract Background Ischemic stroke is an acute and severe neurological disease, reperfusion effective way to reverse brain damage after stroke. However, causes secondary tissue induced by inflammatory responses, called ischemia/reperfusion (I/R) injury. Current therapeutic strategies that control inflammation treat I/R are less than satisfactory. Results We report a kind of shield sword nano-soldier functionalized nanoparticles (monocyte membranes-coated rapamycin nanoparticles, McM/RNPs)...

Interactions between bacteria and minerals at low temperatures often lead to accelerated alteration transformation of mineral phases through dissolution precipitation. Here we report the reductive ferrihydrite, goethite, hematite, magnetite by sulfate-reducing bacterium Desulfovibrio desulfuricans strain G-20. The goal this study was: (1) investigate iron reduction G-20 using as sole electron acceptor (2) determine whether could be enhanced during bacterial sulfate reduction. In absence...
Distinct morphological characteristics of magnetite formed intracellularly by magnetic bacteria (magnetosome) are invoked as compelling evidence for biological activity on Earth and possibly Mars. Crystals produced extracellularly a variety including Geobacter metallireducens GS-15, thermophilic bacteria, psychrotolerant are, however, traditionally not thought to have nearly distinct morphologies. The size shape extracellular depend the culture conditions type bacteria. Under typical CO 2...
ABSTRACT The isoprenoid lipid crenarchaeol is widespread in hot springs of California and Nevada. Terrestrial marine data together suggest a maximum relative abundance at ∼40°C. This warm temperature optimum may have facilitated colonization the ocean by (hyper)thermophilic Archaea major radiation Crenarchaeota .
