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 ...

The sequence of spiral arm classes: Observational signatures of persistent spiral density waves in grand-design galaxies

, 2019
International audienceAbstract We investigate how the properties of spiral arms relate to other fundamental galaxy properties. To this end, we use previously published measurements of those properties, and our own measurements of arm-interarm luminosity ...

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

Experimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
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 ...

VENUS: Strong-lensing Model of MACS J1931.8-2635: Revealing the Farthest Multiply Imaged Supernova

The Astrophysical Journal
We present a parametric strong-lensing model for the galaxy cluster MACS J1931.8-2635 ( z _l  = 0.35), accompanying the detection of the spectroscopically confirmed SN Eos at z = 5.13. We identify 10 new multiple-image systems in recent VENUS JWST/NIRCam

Solvent‐Guided Chiral Assemblies and Chemical Doping of OEG‐Functionalized Conjugated Polymers

Advanced Materials, Volume 38, Issue 45, 13 August 2026.
Solvent‐dependent aggregation pathways dictate whether conjugated polymers form chiral lyotropic liquid‐crystalline assemblies or achiral packed aggregates. Mapping solvent‐controlled β₁ and β2 states reveals that weaker backbone association favors β₁ aggregates and reorganizable twisted mesophases, whereas stronger backbone association favors β2 ...

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 ...

Immuno‐Informatics Design of Multi‐Epitope Vaccine Candidate Against Anaplasma phagocytophilum Using Major Surface Protein 4 (MSP‐4) Antigen

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background and Aims Bovine anaplasmosis is an intracellular tick‐borne, non‐contagious disease caused by gram‐negative bacteria of the family Anaplasmataceae and order Rickettsia. Anaplasma phagocytophilum is the etiological agent for human granulocytic anaplasmosis associated with severe health implications in parts of Europe and the USA and ...

Statistical Survey of Cosmic Noise Absorption in Conjunction With Plasma Wave Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using a decade of observations from the Canadian Geospace Observatory Riometer Network (GO‐RIO), we selected an east‐west subset of stations near L∼7 $L\sim 7$ to classify cosmic noise absorption (CNA) (a proxy for enhanced D‐region ionization) into two morphologies, simultaneous and drifting, based on the relative timing of signals across the
