Cell Proliferation, EarlyView.By assembling cortical‐hypothalamic circuits, we show that cortical input protects hypothalamic neurons from fatty acid‐induced damage, which activates PGC1α to boost mitochondrial function. This reveals a cortico‐hypothalamic axis that defends against metabolic stress.

Groundwater, EarlyView.Pit lakes in semiarid and arid regions are often assumed to be terminal sinks for groundwater following mine closure. Using synthetic numerical modeling, we demonstrate that evaporation‐driven density gradients can reverse this behavior, transforming pit lakes into throughflow systems and potentially increasing salinity in adjacent aquifers.

From EM to AI: Multiscale imaging of the secretory pathway with insights from plant cells
Journal of Microscopy, EarlyView.Abstract The secretory pathway is a central and evolutionarily conserved feature of eukaryotic cells, responsible for protein and lipid trafficking, membrane biogenesis, signalling, and cellular homeostasis. Its complexity, dynamic behaviour, and nanoscale organisation have made it a longstanding target of microscopy‐driven investigation.

Shield materials recommended for space power nuclear reactors [PDF]
Lithium hydride is recommended for neutron attenuation and depleted uranium is recommended for gamma ray attenuation. For minimum shield weights these materials must be arranged in alternate layers to attenuate the secondary gamma rays efficiently.

Iran's Forward Defense in Sub‐Saharan Africa
Middle East Policy, EarlyView.Abstract This article examines Iran's security and defense initiatives in sub‐Saharan Africa between 1990 and 2024 and how they reflect the extraterritorial application of the regime's forward defense doctrine. In response to the long‐term erosion of its homeland defense capabilities since the Iran‐Iraq War of the 1980s—driven by infrastructure ...

Cavity temperature and flow characteristics in a gas-core test reactor [PDF]
A test reactor concept for conducting basic studies on a fissioning uranium plasma and for testing various gas-core reactor concepts is analyzed. The test reactor consists of a conventional fuel-element region surrounding a 61-cm-(2-ft-) diameter cavity ...

Signals, Red Lines, and Collision: The Israel‐Iran Spiral and US Intervention
Middle East Policy, EarlyView.Abstract The Iran War erupted in February 2026 without UN authorization, and Washington's rationales—Iranian nuclear ambitions, missile capacity, and proxy threats—map more closely onto Israeli than US security interests. Why have we seen two major conflicts between these belligerents in less than one year?

Frontiers in Earth ScienceThe Motianling pluton represents a characteristic U-bearing granite pluton in South China. Biotite serves as an indicator for the mineralization of metals such as Cu, Sn, and W in granite. Previous studies have extensively investigated the U metallogenic

Plant, Cell &Environment, EarlyView.ABSTRACT Legume plants can interact with nitrogen‐fixing rhizobia bacteria and arbuscular mycorrhizal fungi (AMF) simultaneously, forming a tripartite symbiotic association. Co‐inoculation studies performed on a variety of legumes have shown that rhizobia and AMF influence each other when they co‐occur in tripartite association and affect host plant ...
