Arginine Metabolic Disruption Impairs Hair Regeneration via ROS‐Mediated Inactivation of mTOR Signaling in Androgenetic Alopecia

Advanced Science, EarlyView.
Arginine deficiency accelerates androgenetic alopecia. Serum metabolome shows reduced circulating arginine, while local metabolic disruption depletes follicular reserves, triggering reactive oxygen species (ROS) accumulation and mTOR suppression that induce hair miniaturization.

Stiffness‐Tunable Neurotentacles for Minimally Invasive Implantation and Long‐Term Neural Activity Recordings

Advanced Science, EarlyView.
A hydraulically actuated “Neurotentacle” probe offers tunable stiffness for precise implantation into the deep brain without rigid shuttles or dissolvable coatings. It stiffens during insertion to penetrate tissue and softens afterward to minimize damage and enable stable long‐term recordings.

Spin‐Orbit Angular Momentum Conversion in Coupled Nonparaxial Bessel Acoustic Vortices

Advanced Science, EarlyView.
This study gives a formulaic description of the spin‐orbit angular momentum (AM) conversion in coupled fields of two nonparaxial Bessel acoustic vortices. Experimental results of wave field measurements provide compelling evidence for spin‐orbit AM conversion via passive artificial structures.

A Novel Class of Multi‐substituted Diaryl Scaffold Derivatives Inhibit Glioblastoma Progression by Targeting CD155

Advanced Science, EarlyView.
Structural modification of clofoctol yielded a novel blood‐brain barrier‐permeable compound, B7, featuring a multi‐substituted diaryl scaffold. B7 demonstrates potent anti‐glioblastoma activity by suppressing glioblastoma stem cells proliferation, migration, and invasion through interactions with five key residues of poliovirus receptor cell adhesion ...
