Ultrafast Adhesion/Friction Bidirectionally Switchable Control by Vibration

Advanced Functional Materials, Volume 36, Issue 8, 26 January 2026.
Bioinspired gradient smooth architectures enable vibration‐switchable adhesion/friction with 62.02 kPa adhesion strength, 131.57 kPa shear strength, tilt angles ≥ 3°, roughness ≥ Ra 0.8 µm, 400 Hz antivibration robustness, and dual‐mode control. The synergy of geometry optimization and vibration modulation tuning bridges multidomain adaptability and ...

Overnight sleep affects the stability of neuropsychological classification in mild cognitive impairment

Alzheimer's &Dementia, Volume 22, Issue 1, January 2026.
Abstract INTRODUCTION Reversion to normal cognition in mild cognitive impairment (MCI) is relatively common. This study tested whether total sleep time (TST) and sleep efficiency (SE) on the night before cognitive testing predicts MCI reversion. METHODS Fifty‐eight community‐dwelling older adults with MCI (mean age = 75 years) participated.

Optimization of High‐κ HfO2 Transistor Dielectrics by Atomic Layer Deposition as an Enabler of Novel Thin‐Film Circuits and Sensors

Advanced Physics Research, Volume 5, Issue 1, January 2026.
We explore the integration of atomic layer deposited (ALD) HfO2 dielectric films with solution‐processed In2O3 thin‐film transistors (TFTs) for a silicon chip‐free temperature sensor label. A voltage divider circuit is integrated with a supercapacitor power source, a thermal sensor, and an irreversible visual indicator (IVI), allowing for temperature ...

An Energetic Tradeoff Best Explains Parturition Timing in Grizzly Bears

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Capitalizing on latitudinal denning‐chronology variation among four grizzly bear populations in interior North America, and using grizzly bear parturition dates (27 Dec–28 Feb) previously predicted from anomalous daily motion counts, we found evidence supporting the hypothesis that birth is optimally timed relative to den exit to balance an energetic ...
