Implantable devices rely on batteries that demand surgical replacement, posing risks, and financial burdens. Ultrasound energy transfer (US‐ET) offers a revolutionary wireless alternative but struggles with efficiency. The presented dielectric‐ferroelectric‐boosted US‐TENG (US‐TENGDF‐B) is thin, flexible, and biocompatible that provides high‐efficiency

Intracellular energy controls dynamics of stress-induced ribonucleoprotein granules
Stress granules are associated with neurodegenerative diseases. Here, Wang et al. found intracellular energy deficiencies trigger a unique type of granules and disrupt granule disassembly through 4EBP1/eIF4A.

Microneedles with Interdigitated Electrodes for In Situ Impedimetric VEGF Sensing
An electrochemical device for transdermal monitoring based on flexible polylactide microneedles with interdigitated electrodes enables continuous monitoring of vascular endothelial growth factor (VEGF) in interstitial fluid. Gold‐coated microneedles functionalized with anti‐VEGF antibodies, provide an in situ detection platform with high sensitivity ...

Compacton solutions and (non)integrability for nonlinear evolutionary PDEs associated with a chain of prestressed granules [PDF]
We present the results of study of a nonlinear evolutionary PDE (more precisely, a one-parameter family of PDEs) associated with the chain of pre-stressed granules. The PDE in question supports solitary waves of compression and rarefaction (bright and dark compactons) and can be written in Hamiltonian form. We investigate {\em inter alia} integrability

Pulse Dynamics in a Chain of Granules With Friction [PDF]
We study the dynamics of a pulse in a chain of granules with friction. We present theories for chains of cylindrical granules (Hertz potential with exponent $n=2$) and of granules with other geometries ($n>2$). Our results are supported via numerical simulations for cylindrical and for spherical granules ($n=5/2$).

Tough and Fast Thermoresponsive Hydrogel Soft Actuators
This work develops tough, fast‐responding thermoresponsive double‐network hydrogels that combine excellent mechanical strength with rapid actuation. Composed of PNIPAm and ether‐based polyurethane, the hydrogels achieve ≈8 MPa compressive stress and ≈30% contractile stroke within 2 min at 50 °C, enabling temperature‐responsive fluid flow switching for ...

Deubiquitination and the regulation of stress granule assembly [PDF]
Stress granules (SGs) are evolutionarily conserved ribonucleoprotein (RNP) structures that form in response to a variety of environmental and cellular cues. The presence of these RNP granules has been linked to a number of human diseases, including neurodegenerative disorders like amyotrophic lateral sclerosis (ALS) and spinocerebellar ataxia type 2 ...

Excitation of stellar p-modes by turbulent convection : 2. The Sun [PDF]
Acoustic power and oscillation amplitudes of radial oscillations computed for a solar model are compared with solar seismic observations. The oscillations are assumed stochastically excited by turbulence. The numerical computations are based upon a theoretical formulation of the power going into solar like oscillation modes as proposed by Samadi et al.

Enhanced Performance 3‐D Printed PLA Parts through a Photo‐Initiator Mediated UV‐Curing
This solvent‐free method enhances 3‐D printed PLA parts by incorporating photo‐initiators during fabrication, followed by up to 3 min UV treatment. This process improves PLA's mechanical properties, including a 64% increase in tensile strength, while addressing weak interlayer bonding and outdoor sensitivity.
