By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

McScatter: a Simple Three-Body Scattering Package with Stellar Evolution
We describe a simple computer package which illustrates a method of combining stellar dynamics with stellar evolution. Though the method is intended for elaborate applications (especially the dynamical evolution of rich star clusters) it is illustrated ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Axially Symmetric Post-Newtonian Stellar Systems
We introduce a method to obtain self-consistent, axially symmetric disklike stellar models in the first post-Newtonian (1PN) approximation. By using in the field equations of the 1PN approximation a distribution function (DF) corresponding to a ...

Cooperative Phenomena in Stellar Dynamics [PDF]
The dispersion relations for small amplitude waves in systems of gas and stars in relative motion are derived by methods developed for plasma physics, the interstellar gas being treated as a hydrodynamic fluid and the stars as a collisionless gas. The classical Jeans' minimum wavelength for instability in a gas is fundamentally reduced by relative ...

Molecular bases of circadian magnesium rhythms across eukaryotes
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Dissecting the 3D structure of elliptical galaxies with gravitational lensing and stellar kinematics
The combination of strong gravitational lensing and stellar kinematics provides a powerful and robust method to investigate the mass and dynamical structure of early-type galaxies.

NGC 1300 dynamics – I. The gravitational potential as a tool for detailed stellar dynamics [PDF]
In a series of papers, we study the stellar dynamics of the grand design barred-spiral galaxy NGC 1300. In the first paper of this series, we estimate the gravitational potential and we give it in a form suitable to be used in dynamical studies.

This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
