Dynamics of small-scale convective motions [PDF]
A&A 598, A126 (2017), 2016 Previous studies have discovered a population of small granules with diameters less than 800 km showing differing physical properties. High resolution simulations and observations of the solar granulation, in combination with automated segmentation and tracking algorithms, allow us to study the evolution of the structural and physical properties of ...

Background-deflection Brillouin microscopy reveals altered biomechanics of intracellular stress granules by ALS protein FUS [PDF]
, 2018 Altered cellular biomechanics have been implicated as key photogenic triggers in age-related diseases. An aberrant liquid-to-solid phase transition, observed in in vitro reconstituted droplets of FUS protein, has been recently proposed as a possible ...

Stress fluctuations and shear thickening in dense granular suspensions [PDF]
, 2019 We experimentally investigate the rheology and stress fluctuations of granules densely suspended in silicone oil. We find that both thickening strength and stress fluctuations significantly weaken with oil viscosity $\eta_0$. Comparison of our rheological results to the Wyart-Cates model for describing different dynamic jamming states suggests a ...

Analyzing plant stress granules in response to plant viruses [PDF]
, 2018 Plant viruses have the ability to redirect host machineries and processes to establish a productive infection. Virus-host interactions lead to the reprogramming of the plant cell cycle and transcriptional controls, inhibition of cell death pathways ...

Stress granules, P-bodies and cancer [PDF]
Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2015 Cancer cells are exposed to adverse conditions in the tumor microenvironment, and utilize post-transcriptional control mechanisms to re-program gene expression in ways that enhance cell survival. Stress granules and processing bodies are RNA-containing granules that contribute to this process by modulating cellular signaling pathways, metabolic ...

PARP1 Activation Controls Stress Granule Assembly after Oxidative Stress and DNA Damage
Cells, 2022 DNA damage causes PARP1 activation in the nucleus to set up the machinery responsible for the DNA damage response. Here, we report that, in contrast to cytoplasmic PARPs, the synthesis of poly(ADP-ribose) by PARP1 opposes the formation of cytoplasmic ...

Polyphosphate granule biogenesis is temporally and functionally tied to cell cycle exit during starvation in Pseudomonas aeruginosa [PDF]
, 2017 Polyphosphate (polyP) granule biogenesis is an ancient and ubiquitous starvation response in bacteria. Although the ability to make polyP is important for survival during quiescence and resistance to diverse environmental stresses, granule genesis is ...

Well-Ordered "Ripple-Shaped" Microstructures of Mn Thin Films on GaAs Substrates [PDF]
Advanced Science, Engineering and Medicine, Volume 11, Number 11,
November 2019, pp. 1142-1147(6), 2019 This study was aimed to investigate the thickness dependent morphological changes of Mn films deposited on GaAs substrates by thermal evaporation technique. Ni films were deposited under same conditions to perform comparative study of the morphological changes with respect to the Mn films.
