Lsm7 phase-separated condensates trigger stress granule formation
Nature Communications, 2022 Stress granules are non-membranous organelles connected to stress responses and age-related disease. Here, the authors identify a conserved yeast protein, Lsm7, that facilitates stress granule formation through dynamic liquid-liquid phase separation ...

Advanced Materials, EarlyView.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

Cell Reports, 2018 Summary: How cells adapt to varying environmental conditions is largely unknown. Here, we show that, in budding yeast, the RNA-binding and stress granule protein Pub1 has an intrinsic property to form condensates upon starvation or heat stress and that ...

Compacton solutions and (non)integrability for nonlinear evolutionary PDEs associated with a chain of prestressed granules [PDF]
arXiv, 2017 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]
, 2003 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 ($n=5/2$).

Deubiquitination and the regulation of stress granule assembly [PDF]
Current Genetics, 2016 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 ...

Tough and Fast Thermoresponsive Hydrogel Soft Actuators
Advanced Materials Technologies, EarlyView.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 ...

Excitation of stellar p-modes by turbulent convection : 2. The Sun [PDF]
, 2001 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
Advanced Materials Technologies, EarlyView.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.
