Detoxing the brain: Understanding digital backlash in the context of the media effects tradition
In the public debate, problems due to excessive use of digital media are often explained with reference to neurological functions and addressed through calls for self-regulation.

Advanced Science, EarlyView.Geometric constraint reconfiguration enables a rigid–foldable kirigami‐inspired mechanism to switch between twisting, directional translation, and self‐locking states. By encoding multifunctionality directly into its architecture, the mechanism achieves multimodal motion and passive locking without reassembly, providing a compact platform for adaptive ...

Logic-dynamic approach to fault diagnosis in mechatronic systems
International Journal of Advanced Robotic Systems, 2008 This paper presents a problem of fault detection and isolation (FDI) in mechatronic systems described by nonlinear dynamic models with such types of no differentiable nonlinearities as saturation, Coulomb friction, backlash, and hysteresis. To solve this

Bistable Networks Enable Complex Shape Changes
Advanced Science, EarlyView.Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

Seeing is believing: Voluntary gender quotas change female leadership stereotypes
Research & PoliticsCan gender quotas voluntarily adopted by political parties alter stereotypical views about women in politics? This article examines Namibia’s SWAPO, an electorally dominant party that introduced a 50/50 gender quota in 2013.

Advanced Science, EarlyView.Neuromodulation strategies are increasingly needed to stimulate, restore, or replace altered neuronal activity in disease. Cobalt ferrite‐barium titanate (CFO–BTO) magnetoelectric nanoparticles convert low‐intensity static magnetic fields into local electrical modulation of cortical networks.

Internal model control of mechanics systems with backlash
, 2010 El juego mecánico u holgura (backlash en inglés) aparece frecuentemente en dispositivos mecánicos cuya función es transmitir un par, y es provocado por el desgaste propio de las piezas que operan bajo contacto (p.ej., trenes de engranes). Su efecto puede

Dimple‐Encoded Reprogrammable Origami
Advanced Science, EarlyView.Local snap‐through of bistable dimples turns flat elastic sheets into reprogrammable origami structures. Interaction‐guided dimple arrays act as angle‐programmable hinge bands, enabling one sheet to morph into distinct polygonal and three‐dimensional configurations while retaining stable shapes for deployable and protective functions.

Advanced Science, EarlyView.Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

Paraborg: Paramedic Cyborg Insects for In Situ Emergency Drug‐Delivery
Advanced Science, EarlyView.This work introduces Paraborg, a human‐supervised paramedic cyborg‐insect platform that combines controllable locomotion, onboard imaging, and an auto‐injection mechanism for in situ drug‐delivery. By demonstrating reliable navigation, target stabilization, injector launch, and multi‐insect teamwork, the study extends cyborg insects from survivor ...
