The Astrophysical JournalPulsating stars are universally recognized as precise distance indicators and tracers of stellar populations. Their variability, combined with well-defined relationships between pulsation properties and intrinsic evolutionary parameters such as ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Tidal Coplanarization of Circumbinary Planetary Systems through Stellar Cassini States
The Astrophysical JournalCircumbinary planets (CBPs) currently identified are in nearly coplanar configurations relative to their host binaries, yet the dynamical origin of this preference remains unclear.

Chromospheric activity and stellar evolution [PDF]
, 1973 A study of stellar chromospheres based on the internal structure of particular stars is presented. Used are complex flow diagrams of the linkage paths between mass loss, angular momentum loss, magnetic field from the turbulent dynamo and its relations to

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

, 2013 This is a non-exhaustive review of what we have learned from 10+ years of cluster studies with multi-object spectrographs at 10 m-class telescopes about what stars do with their birth-cloud lithium.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Analysis of DQZ White Dwarf Evolution through Procyon
The Astrophysical JournalProcyon is a great system to probe stellar evolution of noninteracting binaries. We present an extensive grid of Modules for Experiments in Stellar Astrophysics evolutionary tracks to constrain the evolution of Procyon A and B. We systematically vary the

Linking 1D Stellar Evolution to 3D Hydrodynamical Simulations [PDF]
, 2015 In this contribution we present initial results of a study on convective boundary mixing (CBM) in massive stellar models using the GENEVA stellar evolution code.
