Impact of Virus‐Mediated Modifications in Bacterial Communities on the Accumulation of Soil Organic Carbon

Advanced Science, EarlyView.
This study illustrates the impact of viruses on carbon cycling in soils with different availabilities of carbon. In conditions of low carbon availability, viruses adopt a lysogenic lifestyle, integrate into the host genomes and facilitate the degradation of carbon.

WTAP Mediated m6A Modification Stabilizes PDIA3P1 and Promotes Tumor Progression Driven by Histone Lactylation in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
This study reveals a new mechanism by which PDIA3P1 regulates the progression of esophageal squamous cell carcinoma (ESCC). PDIA3P1 upregulates the expression of GLUT1 and HK2, promoting glycolysis and lactate production. Lactate upregulates the lactylation level of histone H4K8 and activates the transcription of target gene BMP7, ultimately ...

Stirring Without Stirrers: Polymer Fouling‐Driven Mass Transport Unlocks Order‐of‐Magnitude Gain in Electrochemiluminescence

Advanced Science, EarlyView.
Strategic electrode fouling enhances mass transport, primarily through electrochemically actuated lateral density gradients. Engineered fouling induces flow velocities up to 0.4 cm s⁻¹ in otherwise quiescent systems. Sub‐millimeter plastic features boost local rates by up to 290%, while micrometer‐scale arrays yield a 30% net electrolysis gain ...

Electrochemical Degradation of Plastic Waste Coupled with Hydrogen Evolution in Seawater Using Rosette‐Like High‐Entropy Oxides

Advanced Science, EarlyView.
Rosette‐like high‐entropy NiCoFeMnAlOx enable the electrochemical degradation of PGA plastic waste in seawater, coupling glycolic acid oxidation with hydrogen evolution. Abundant OH* species lower energy barriers for C─C and C─H bond activation, while in situ and theoretical studies reveal the catalytic mechanism.

Precursor Inhomogeneities Influence the Properties of Multimetal Oxides as Shown for LiNi0.5Mn1.5O4 Derived from Hydrothermally Synthesized Precursors

Advanced Science, EarlyView.
Correlative Raman and scanning electron microscopies are used for identifying compositional differences on the micrometer length scale in LiNi0.5Mn1.5O4 cathode materials, and it is shown that these compositional differences can be linked to the electrochemical signature of the material. Abstract Co‐precipitation is an attractive means for synthesizing
