Advanced Materials Technologies, Volume 11, Issue 15, 7 August 2026.Flexible Chitosan‐glycerol sensor integrated with porous laser‐induced graphene (LIG) electrodes enable room‐temperature chemiresistive detection of ammonia (NH3) and proof‐of‐concept detection of fish spoilage. ABSTRACT We report a metal‐free sensor platform combining laser induced graphene (LIG) electrodes with drop‐deposited, glycerol‐plasticized ...

Advanced Theory and Simulations, Volume 9, Issue 8, August 2026.The graphical abstract presents the unit‐cell architecture of the proposed transparent metasurface polarization converter, featuring a low‐filling‐factor rotated copper frame on PET, an air‐cavity spacer, and an ITO ground plane. The design enables optical transparency, lightweight construction, and ultra‐broadband, high‐efficiency cross‐polarization ...

Metasurface‐Enabled Active‐Like Passive Radar
Advanced Science, Volume 13, Issue 44, 7 August 2026.A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Advanced Science, Volume 13, Issue 45, 13 August 2026.A biomimetic artificial intelligence system, PancDS, has been developed to distinguish pancreatic ductal adenocarcinoma from mass‐forming pancreatitis by adaptively integrating clinical data, radiomics, and deep learning features. Validated across multicenter, reader‐study, and prospective settings, PancDS improves diagnostic accuracy, particularly for

Ecology and Evolution, Volume 16, Issue 8, August 2026.The timing of migratory departure reflects a balance between endogenous schedules and transient environmental opportunities. By linking GPS‐derived departure events with hourly atmospheric data, we demonstrate that wind assistance strongly increases departure probability in Brent Geese, while this selectivity weakens over time as migratory urgency ...

Abalone Mortality Associated With Hypoxia in Tidepools During a Summer Heatwave
Ecology and Evolution, Volume 16, Issue 8, August 2026.Abalone (Haliotis roei) inhabit tidepools on intertidal platforms. During heatwaves and periods of low tide, water exchange in tidepools ceases. While temperatures in tidepools remain constant, oxygen levels are significantly reduced. Abalone mortality in tidepools is associated with oxygen depletion rather than thermal stress.
