Active Force Dynamics in Red Blood Cells Under Non‐Invasive Optical Tweezers

open access: yesAdvanced Science, EarlyView.
A non‐invasive method combines low‐power optical tweezers with high‐speed microscopy to simultaneously monitor local membrane forces and displacements in single human red blood cells. This dual‐channel approach reveals a mechano‐dynamic signature that correlates the cell's metabolic state with its mechanical activity. This energetic framework serves as

Osmotic Tension Asymmetry Drives Electrotactic Migration via PDLIM7‐Polarized Microfilament Coordination in Breast Cancer Cells

open access: yesAdvanced Science, EarlyView.
This study establishes an electric field‐induced directional migration model using fluorescence tension probes to visualize microfilament forces and intracellular osmotic pressure dynamics in the electrotactic migration of breast cancer cells. This model delineates how electromechanical interactions among membrane potential, ion channels, OP, traction ...

Electric vehicle possibilities using low power and light weight range extenders [PDF]

open access: yes, 2014
Electric cars have the disadvantage of a limited range, and drivers may experience a range anxiety. This range anxiety can be solved by adding a range extender. But, the range extender should be light so as not to significantly increase the weight of the

Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion

open access: yesAdvanced Science, EarlyView.
In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...

Neuroprotective Effects of Time‐Restricted Feeding Combined With Different Protein Sources in MPTP‐Induced Parkinson's Disease Mice Model and Its Modulatory Impact on Gut Microbiota Metabolism

open access: yesAdvanced Science, EarlyView.
Time‐restricted feeding (TRF) exerts protein‐dependent neuroprotective effects in an MPTP‐induced Parkinson's disease model. In casein‐fed mice, TRF improves gut barrier integrity and reduces neuroinflammation, possibly via modulation of Allobaculum and BCAAs.
