Interaction Between Convection and Pulsation
Living Reviews in Solar Physics, 2015 This article reviews our current understanding of modelling convection dynamics in stars. Several semi-analytical time-dependent convection models have been proposed for pulsating one-dimensional stellar structures with different formulations for how the

FEBS Letters, EarlyView.This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Constraints on White Dwarf Hydrogen Layer Masses Using Gravitational Redshifts
The Astrophysical JournalThe hydrogen envelope is the outermost layer of a DA white dwarf; it makes up the entirety of the stellar photosphere, and yet its typical extent is difficult to model theoretically and remains poorly observationally constrained.

The Shape of Stellar Convection
Recent space missions such as Kepler, TESS, and soon PLATO have provided an abundance of high-quality stellar data, highlighting the need for more accurate models of stellar structure and evolution.

FEBS Letters, EarlyView.Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

The Interplay of Stellar Evolution and Collisions in Galactic Nuclei
The Astrophysical JournalNuclear star clusters (NSCs) surrounding supermassive black holes (SMBHs) are among the densest stellar environments in the Universe. In these environments, collisions can shape the stellar mass function and produce exotic stellar populations.

Seismological insights into solar and stellar magnetic activity cycles
EPJ Web of Conferences, 2017 The Sun’s magnetic activity cycle varies primarily on a time scale of approximately 11yrs from minimum to maximum and back again. It is well-known that the properties of the Sun’s acoustic oscillations are affected by the near-surface internal magnetic ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

VIPERS: Stellar population properties of early-type galaxies [PDF]
, 2016 We present stellar population properties of early-type galaxies from the VIMOS Public Extragalactic Redshift Survey (VIPERS) based on the spectral measurements of ∼ 4000 galaxies with stellar masses from 10^{10} to 10^{12} {[M_{☉}]} in the redshift range
