Advanced Science, EarlyView.This study developes a universal colorimetric ICA platform that integrates broad‐spectrum recognition by 4‐mercaptophenylboronic acid with dual signal enhancement—both colorimetric and catalytic—mediated by a biomimetic magnetic nanozyme. This platform, for the first time, enables simple, convenient, ultrasensitive, and simultaneous screening of ...

Loss of STARD7 Triggers Metabolic Reprogramming and Cell Cycle Arrest in Breast Cancer
Advanced Science, EarlyView.Breast cancer cells undergo metabolic and transcriptomic reprogramming to support aberrant cell proliferation. Their mitochondria rely on the transfer of phosphatidylcholine from the endoplasmic reticulum to their membranes by STARD7, a candidate upregulated in breast cancer, to be functional.

Advanced Science, EarlyView.This study deciphers maternal‐driven microbial transmission in pigs using a deep learning model (maternal–offspring microbial transmission model), identifying Christensenellaceae R‐7 group as a key transmitted taxon. Filtered galacto‐oligosaccharides‐targeted Christensenellaceae R‐7 group alters offspring microbial functions via maternal ...

Advanced Science, EarlyView.This study combined microscale 3D‐printing with 2D Ti3C2Tx MXene nanosheets to produce electroconductive microfibrous micro‐meshes. By embedding these MXene‐functionalized micro‐meshes within a growth‐supportive macroporous extracellular matrix (ECM)‐based biomaterial, multifunctional biomimetic MXene‐ECM scaffolds were developed.

Group A Streptococcus strains causing meningitis without distinct invasive phenotype
MicrobiologyOpenGroup A streptococcal (GAS; aka Streptococcus pyogenes) meningitis is a fulminant disease associated with high morbidity and mortality. To elucidate the mechanisms underlying the invasiveness of GAS in meningitis, we compared GAS isolates derived from ...
