Probing an Ultracold-Atom Crystal with Matter Waves

, 2012
Atomic quantum gases in optical lattices serve as a versatile testbed for important concepts of modern condensed-matter physics. The availability of methods to characterize strongly correlated phases is crucial for the study of these systems. Diffraction

Vm–MSI: a Vancomycin–Antimicrobial Peptide Conjugate Combating Resistant Bacteria and Broadening the Antimicrobial Spectrum

Advanced Science, EarlyView.
A series of vancomycin‐antimicrobial peptide conjugates is synthesized and evaluated to identify the optimal combination. Vm‐MSI, selected from multiple candidates, exhibited potent activity against vancomycin‐resistant and Gram‐negative bacteria by disrupting membranes and inducing oxidative stress, thereby expanding vancomycin's antibacterial ...

Disentangling the syntrophic electron transfer mechanisms of Candidatus geobacter eutrophica through electrochemical stimulation and machine learning

Scientific Reports, 2021
Interspecies hydrogen transfer (IHT) and direct interspecies electron transfer (DIET) are two syntrophy models for methanogenesis. Their relative importance in methanogenic environments is still unclear. Our recent discovery of a novel species Candidatus

A two-fluid helicity transport model for flux-rope merging

, 2014
A two-fluid model for canonical helicity transport between merging flux-ropes is developed. Relative canonical helicity is defined here as the gauge invariant helicity of the canonical momentum of a given species, and represents the generalization of ...

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

Advanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Intertidal Warfare: Synergistic Allelopathy Mediates Spatial Competition between Two Marine Calcareous‐Shelled Sessile Organisms

Advanced Science, EarlyView.
This study reveals a hidden chemical weapon among calcareous‐shelled sessile organisms in the intertidal zone: the barnacle Balanus albicostatus releases a synergistic blend of palmitic acid and 1‐palmitoyl‐sn‐glycero‐3‐phosphocholine as the allelochemical with the inhibitory activity against attachment of the mussel Vignadula atrata, which may mediate

Diverse syntrophic partnerships from deep-sea methane vents revealed by direct cell capture and metagenomics [PDF]

, 2008
Microorganisms play a fundamental role in the cycling of nutrients and energy on our planet. A common strategy for many microorganisms mediating biogeochemical cycles in anoxic environments is syntrophy, frequently necessitating close spatial proximity ...
