Diversity, transfer potential, and transcriptional activity of virus‐carried antibiotic resistance genes in global estuaries

iMetaOmics, EarlyView.
Estuaries are vital hotspots for antibiotic resistance genes (ARGs) due to substantial antibiotic pollution. Although viruses have been proposed as key reservoirs and important disseminators of ARGs in environments, their contribution to the estuarine antibiotic resistome remains largely unknown.

A strategy for modulation of permittivity in manganese doping to induce lattice distortion

InfoMat, EarlyView.
Manganese atoms are doped into the NiCo2O4 spinel structure by atomic substitution, which increases structural stability through the formation of manganese–oxygen bonds. The resulting lattice distortion leads to a significant increase in dielectric permittivity. Achieving an electromagnetic wave reflection loss of −63.40 dB thus provides useful insight

High‐mobility suspended MoS2 devices with tunable threshold voltage

InfoMat, EarlyView.
Due to their atomic‐scale thickness, two‐dimensional materials (2DMs) are highly sensitive to their environment, including the substrate. By fabricating various suspended molybdenum disulfide devices, this study demonstrates that the suspended structure can shield the influence of the substrate on the properties of 2DMs, thereby enabling better ...

Promise‐Keeping Reputations in an Investment Game: An Experimental Investigation

International Studies of Economics, EarlyView.
ABSTRACT We design a controlled laboratory experiment to mitigate moral hazard problems in livestream shopping when sellers make promises to buyers. In our experiment, the promise‐keeping reputation mechanism allows sellers to send promises to buyers while buyers can observe the sellers' historical promise‐keeping records. Results demonstrate that bare

Acute and Chronic Toxicity of Sediments Containing Platinum and Palladium on Freshwater Benthic Organisms Chironomus riparius and Hyalella azteca

Journal of Applied Toxicology, EarlyView.
ABSTRACT The expanding demand for platinum group elements (PGEs) in industrial and medical applications has led to their increasing accumulation in aquatic sediments. However, their ecological impacts remain poorly understood, particularly for sediment‐dwelling invertebrates. This study assessed the toxicity of platinum (Pt) and palladium (Pd) across a

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

Journal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

Assessing the intensity of Late Quaternary humid phases in the Nefud Desert, northern Arabia

Journal of Quaternary Science, EarlyView.
ABSTRACT The climate history of the major dryland zones of the world, such as the Saharo–Arabian Desert belt, plays a key role in the dispersal of early humans through these intermittently inhospitable regions. Here, we assess the relative intensity of Late Quaternary humid phases in northern Arabia through lithological, geochemical, palaeoecological ...

Lake Water and Sediment

Limnology and Oceanography, 1958
Sixteen lakes are described, varying in geology and all but two of low productivity, and including three acid bog types. A method is described for indirect estimation of the sum of Na and K. In lakes generally, low pH is related to low conductivity, but in these coastal lakes the Na in ocean spray keeps up the conductivity even in very acid waters.

Crenarchaeota in Lake Michigan sediment

Applied and Environmental Microbiology, 1997
RNA from Lake Michigan sediment was hybridized with a DNA probe for archaeal 16S rRNA. There was a peak of archaeal rRNA abundance in the oxic zone and another immediately below it. Six contributing species were identified by PCR amplification of extracted DNA with primers specific for archaeal rDNA: two related to Methanosarcina acetivorans and four ...
