Analysis of Melting Phenomena of the Alkali Halides: What Causes the Low Melting Points of the Lithium Halides?

open access: yesJournal of Mass Spectrometry, Volume 61, Issue 6, June 2026.
ABSTRACT The alkali halides, like other polar crystals, melt at high temperatures, but the melting points (Tm) of the lithium halides are conspicuously lower (by about 300 ± 70 K) than expected from reasonable comparisons with the other alkali halides.

Intrinsic conformational equilibria position arrestin‐2 for activation

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract Arrestins regulate G protein‐coupled receptor (GPCR) signaling by undergoing large‐scale conformational rearrangements, yet the solution‐state equilibria that underlie arrestin pre‐activation remain poorly defined. While prior studies identified slow conformational exchange at the interdomain interface, these minor states could not be ...

Microglial Activation Under Hypoxic Conditions in Early Alzheimer's Disease: Can Natural SIRT1 Activators Be Therapeutic Allies in the Inflammation–Energy Axis?

open access: yesPhytotherapy Research, Volume 40, Issue 6, Page 3354-3368, June 2026.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative condition characterized by a preclinical stage that typically lasts for decades. Early on during this time, microglia react to pathological changes and become protective and even transiently delay neurodegeneration.

Can a lizard ride on a housefly?: Navigating uncertainty and moral life in an Accra Zongo, Ghana

open access: yesEthos, Volume 54, Issue 2, June 2026.
Abstract How can uncertainty become a resource for ethical life rather than a threat to it? Focusing on a Zongo community in Accra, Ghana—also known as a “traveler's camp” or “stranger's quarters”—this article examines how people use a creative form of communication called the practice of folding to sustain relationships shaped by conditions of ...

Tracking the Trajectory of Alluvial Channel Adjustment Reveals Along‐River Shifts in Sediment Mobility

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Alluvial rivers adjust their geometry to convey water and sediment downstream. While multi‐river compilations reveal robust downstream scaling relationships, how these patterns manifest along a single river remains poorly constrained. We quantify the coevolution of bankfull width, depth, channel slope, and grain size along 166 km of California'
