Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.Combined approach of electromagnetic (Power) and ultrasound (data harvesting) waves is proposed to address the miniaturized ultrasonic implants. Electromagnetic waves trigger the piezoelectric element to generate the acoustic pulse which is modulated by the variations in the sensor's impedance.

Deep Volumetric Super‐Resolution Imaging in Thick Biological Specimens With Sparse Scanning SIM
Advanced Science, Volume 13, Issue 25, 4 May 2026.Sparse scanning structured illumination microscopy (SS‐SIM) extends the axial depth in super‐resolution fluorescence imaging by combining rapid laser scanning, pixel‐addressed intensity modulation, and sCMOS camera detection. SS‐SIM yields 1.6× lateral and 1.7× axial resolution gains over wide‐field microscopy and enables imaging through 300–600 µm ...

Conservation of Neuron‐Astrocyte Correlated Activity in Developing Sensory Pathways
Glia, Volume 74, Issue 5, May 2026.Astrocytes and neurons in the superior colliculus exhibit spatiotemporal correlated activity before eye opening. Each neuronal wave is followed by a calcium wave in astrocytes. Spillover of glutamate activates mGluR5 and mGluR3 in astrocytes. ABSTRACT Neurons in developing sensory organs exhibit prolonged burst firing before the onset of sensory ...

Pupil Plane Multiplexing for Vectorial Fourier Ptychography
Laser &Photonics Reviews, Volume 20, Issue 9, 6 May 2026.This study proposes a cost‐effective, modality‐adaptive multichannel microscopy framework using pupil‐plane multiplexing. A custom pupil aperture at the Fourier plane encodes channel‐specific transfer functions with spectral or polarization filters, and model‐based reconstruction with channel‐dependent priors decodes them.
