A Refined Adaptive Laboratory Evolution Strategy With Biosensor‐Assisted Selection Resolves the Tolerance–Efficiency Trade‐Off in Toxic Chemical Biosynthesis

Advanced Science, EarlyView.
This study presents a refined adaptive laboratory evolution (ALE) strategy to resolve the trade‐off between tolerance and biosynthetic efficiency in toxic chemical production. Combining in vivo mutagenesis, microdroplet‐based evolution, and biosensor‐assisted selection, this strategy rapidly yields robust “win‐win” phenotypes.

Direct Sequencing of 5‐Methylcytosine and 5‐Hydroxymethylcytosine at Single‐Base Resolution Unravels Their Distinct Roles in Alzheimer's Disease

Advanced Science, EarlyView.
This study introduces two orthogonal sequencing methods, CMD1‐Deaminase sequencing (CD‐seq) and CMD1‐TET bisulfite sequencing (CT‐seq), that enable direct, independent detection of 5mC. Using these approaches together with ACE‐seq or TAB‐seq for 5hmC identification, the study reveals a significant reduction in 5hmC, but not 5mC, in the hippocampus of ...

Phospholipid Remodeling and Tri‐Layer Membrane Reconstruction Mediate Cognitive Effects of Humanized Milk Fat Globules in Neonatal Rats

Advanced Science, EarlyView.
Humanized milk fat globules (MFG) mimic the native composition and structure of human milk, achieved through remodeling of milk fat globule membrane phospholipid composition and reconstruction of the tri‐layer membrane structure. These humanized MFG exhibit improved structural stability and digestibility, and enhance neurodevelopment in formula‐fed rat

Conductive Microneedles Loaded With Polyphenol‐Engineered Exosomes Reshape Diabetic Neurovascular Niches for Chronic Wound Healing

Advanced Science, EarlyView.
This study establishes a bio‐electroceutical interface by synergizing engineered exosome‐derived biological signals with electroconductive microneedle‐delivered electrical cues, achieving dual‐pathway reprogramming of the diabetic neurovascular niches and accelerating wound healing. Abstract Diabetic wound healing remains a major clinical challenge due
