Electron acceptors modulate methane oxidation and active methanotrophic communities in anoxic urban wetland sediments

Applied and Environmental Microbiology
Urban wetlands, although often overlooked, are hotspots for CH4 cycling. However, the understanding of anaerobic CH4 oxidation and microbial responses to different electron acceptors in urban wetlands remains limited. Here, we employed DNA-stable isotope

Using MALDI‐FTICR Mass Spectrometry to Enhance ZooMS Identifications of Pleistocene Bone Fragments Showing Variable Collagen Preservation

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Recent advances in high‐throughput molecular analyses of collagen peptides, especially ZooMS (Zooarchaeology by Mass Spectrometry), have permitted breakthroughs in the analysis of archaeological material that is highly fragmented, a factor that hinders morphological identification.

Identification of the bacterial community that degrades phenanthrene sorbed to polystyrene nanoplastics using DNA-based stable isotope probing

Scientific Reports
In the Anthropocene, plastic pollution has become a new environmental biotope, the so-called plastisphere. In the oceans, nano- and micro-sized plastics are omnipresent and found in huge quantities throughout the water column and sediment, and their ...

Stable-isotope probing implicates Methylophaga spp and novel Gammaproteobacteria in marine methanol and methylamine metabolism

, 2007
The metabolism of one-carbon (C-1) compounds in the marine environment affects global warming, seawater ecology and atmospheric chemistry. Despite their global significance, marine microorganisms that consume C-1 compounds in situ remain poorly ...

Rational design of a lipophilic β‐galactosidase‐responsive near‐infrared probe for in vivo imaging of cellular senescence

Smart Molecules, EarlyView.
We developed a lipophilic near‑infrared probe (DCIP‑AcGal) that is specifically activated by senescence‑associated β‑galactosidase. After intravenous injection, it lights up therapy‑induced tumor senescence in living mice. Its optimized lipophilicity also enables blood‑brain barrier crossing to detect natural brain senescence ex vivo. This probe offers

Boron‐embedded multifunctional nanoplatform toward potential combined boron neutron capture therapy and immunomodulation in glioma

Smart Molecules, EarlyView.
A brain‐targeting multifunctional nanoplatform (DM&Ce6@COF‐Ang) was engineered by employing boron‐enriched APTES‐COF‐1 as both the therapeutic boron agent and the nanocarrier co‐delivery of DMXAA and Ce6. This nanoplatform achieved synergistic tumor‐specific boron delivery, real‐time pharmacokinetic monitoring, and immunomodulation.

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems

Wildlife Biology, EarlyView.
Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

Interactions between prairie dogs and arthropods in grassland ecosystems: a review and research gaps

Wildlife Biology, EarlyView.
Prairie dogs (Cynomys spp.) are an important component of grassland ecosystems of North America where they can alter vegetation composition/structure and physical attributes of grassland habitats through their feeding and burrowing behavior. Impacts of prairie dog presence on many wildlife and plant taxa have been widely studied but research on prairie

Bridging the divide between models of animal‐driven and microbial‐driven biogeochemical cycling: A zoogeochemistry‐informed framework

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Most current terrestrial biogeochemical models formalize biogeochemical cycling as predominantly controlled by processes involving plants and soil microbes. However, growing evidence indicates that above‐ground animals could exert controlling feedback effects that alter

MISIP: a data standard for the reuse and reproducibility of any stable isotope probing-derived nucleic acid sequence and experiment [PDF]

DNA/RNA-stable isotope probing (SIP) is a powerful tool to link in situ microbial activity to sequencing data. Every SIP dataset captures distinct information about microbial community metabolism, process rates, and population dynamics, offering valuable
