, 2016 Nunca fue tan claro como en este siglo XXI que saber es poder, algo que las elites siempre supieron. En la Argentina nunca tuvimos aristocracia y hoy ni siquiera tenemos oligarquía, sino sólo una aspiración elitista de alguna riqueza concentrada que sintetiza su pensamiento bajo el lema de no avivar giles. La polarización del siglo XX está sepultada en

Advanced Science, EarlyView.Inspired by the mimosa, this study develops a flexible triboelectric nanogenerator with a novel microneedle array and battery‐mimetic architecture. The device introduces a spontaneous charge self‐regulation mechanism that confines the electric field below the air breakdown threshold, and achieves an outstanding charge density of 396.50 µC m−2 ...

Revista de la Facultad de Medicina, 1939 La interpretación de la norma universitaria, es la de que la institución debe acomodarse al medio, es decir: desarrollar la inteligencia de las generaciones imprimiéndoles un carácter de conjunto y de aplicación de las enseñanzas, adaptándolas al adelanto de la sociedad en que se vive, para redimir al hombre de la ignorancia, civilizarlo, capacitarlo ...

Albumin‐Bound STING Agonist Reprograms HSPCs to Antitumor Neutrophils Enhancing CD8+ T Cell Immunity
Advanced Science, EarlyView.This study demonstrates that an albumin‐bound STING agonist (Nano ZSA‐51D) reprograms HSPCs to produce antitumor neutrophils with enhanced MHC I–mediated CD8+ T cell activation, thereby sensitizing tumors to α‐PD1 therapy. These findings highlight a strategy to target early hematopoiesis for shaping neutrophil fate and potentiating cancer immunotherapy.

Noninvasive Focal Gene Delivery into the Cerebellum of Non‐Human Primates using Focused Ultrasound
Advanced Science, EarlyView.Focal and non‐invasive viral vector delivery in non‐human primates remains a major challenge in translational neuroscience. Low‐intensity focused ultrasound was used to transiently open the blood–brain barrier and enable targeted gene delivery to the cerebellum.

Solid Ethanol as a Renewable, Low‐Toxicity, Electron‐Beam Direct Write, and Biomedical Material
Advanced Science, EarlyView.3D ice lithography (3DIL) enables the fabrication of intricate submicrometer objects using ethanol as a renewable starting material. This study combines process optimization, structural and material analysis, and biomedical applications, from cell culture scaffolds to the patterning of neurostimulation electrodes, demonstrating performance in both in ...

Advanced Science, EarlyView.This study uses tyrosinase, which is highly expressed in melanoma, to drive porphyrins to polymerize and self‐assemble within tumor cells to form retented microstructures. This process induces immunogenic death and activates immune responses (M1 macrophages, dendritic cells, CD8+T cells), turning “cold” tumors into “hot” tumors.

Advanced Electronic Materials, EarlyView.This work proposes a machine‐vision‐based tool for predicting the thickness of in‐line deposited perovskite films, enabling real‐time decision making to control deposition parameters. The workflow integrates perovskite deposition and annealing with uniformity analysis and minimodule fabrication.
