The Gas-phase Mass–Metallicity Relation for Massive Galaxies at z ∼ 0.7 with the LEGA-C Survey

The Astrophysical Journal
The massive end of the gas-phase mass–metallicity relation (MZR) is a sensitive probe of active galactic nuclei (AGN) feedback that is a crucial but highly uncertain component of galaxy evolution models.

Simulations All the Way Up! An Atheist's Response to the Fine‐Tuning Argument

Analytic Philosophy, EarlyView.
ABSTRACT So the Fine‐tuning Argument goes, because it is so unlikely for the physical constants of the laws of nature to have taken the values that they in fact take, we should significantly raise our credence that God exists. Simulation Arguments argue that our world might be (or, in stronger versions, that it probably is) a mere computer simulation ...

Milky Way’s Metal-poor Stars Display Chemical Transition near the Solar Radius

The Astrophysical Journal Letters
The metal-poor stars of a galaxy offer insights into that galaxy’s early formation processes and accretion history. Here, we investigate whether the metal-poor stars of our Milky Way Galaxy exhibit any characteristic trends in Galactocentric distance ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

Ecological Research, Volume 41, Issue 5, September 2026.
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

The Impact of Initial Composition on Massive Star Evolution and Nucleosynthesis

The Astrophysical Journal
We study the sensitivity of presupernova evolution and supernova nucleosynthesis yields of massive stars to variations of the initial composition. We use the solar abundances from Lodders, and compute two different sets of initial stellar compositions ...

The SVP–FRO6 Module Integrates the Control of Leaf Senescence and Flowering in Arabidopsis

Plant, Cell &Environment, Volume 49, Issue 9, Page 7191-7209, September 2026.
ABSTRACT Plants coordinate major developmental transitions by integrating intrinsic genetic programs with environmental signals, where nutrient availability serves as a critical external factor shaping growth and fitness. Iron (Fe), an essential micronutrient for cellular respiration and photosynthesis, is strictly regulated through sophisticated ...

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

Chemie Ingenieur Technik, Volume 98, Issue 8, Page 514-524, August 2026.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

The Heavy Metal Survey: The Evolution of Stellar Metallicities, Abundance Ratios, and Ages of Massive Quiescent Galaxies since z ∼ 2

The Astrophysical Journal
We present the elemental abundances and ages of 19 massive quiescent galaxies at z ∼ 1.4 and z ∼ 2.1 from the Keck Heavy Metal Survey. The ultradeep LRIS and MOSFIRE spectra were modeled using a full-spectrum stellar population fitting code with variable

Chemogenetic Activation of G12 Signaling Thickens the Epidermis With Enhanced Barrier Function

FASEB BioAdvances, Volume 8, Issue 8, August 2026.
In this study, we investigated the role of G12 signaling in the epidermis using a keratinocyte‐specific chemogenetic approach. Activation of G12 signaling promoted keratinocyte differentiation and enhanced epidermal barrier function by upregulating filaggrin, claudin‐1, and ceramide.
