Estrogen Alleviates Sevoflurane‐Induced Neurotoxicity by Inhibiting ERα‐Tau Binding

Advanced Science, EarlyView.
Sevoflurane‐induced neurotoxicity exhibits sex differences, and estrogen can mitigate these effects; however, its protective action appears to be time‐window dependent, which may be related to the competitive binding of estrogen and Tau to ERα. Abstract Sevoflurane‐induced neurotoxicity is age‐dependent, but the role of sex differences is unclear ...

cGAS Inhibits ALDH2 to Suppress Lipid Droplet Function and Regulate MASLD Progression

Advanced Science, EarlyView.
cGAS is a cytosolic DNA sensor known for innate immune defense. cGAS binds and suppresses ALDH2 are showed, limiting acetyl‐CoA production. cGAS loss activates ALDH2, promoting histone acetylation, lipogenesis, and lipid droplets accumulation. cGas‐/‐ mice on a high‐fat diet show signs of worsened MASLD.

Flickers, Bursts, and Dips: Detecting Rapid Variability with the g(2) Autocorrelation Function

The Astrophysical Journal
Rapid optical transient events can be hard to detect because of the limited number of photons they produce. I discuss a method of inferring the presence of fast, chaotic variability in photometry using the normalized autocorrelation function, what is ...

Synaptic Dysfunction in the Anterior Cingulate Cortex Underlies Pain‐Anxiety Comorbidity in a Mandibular Asymmetry Mouse Model

Advanced Science, EarlyView.
This study establishes a mandibular asymmetry (MA) mouse model that recapitulates chronic orofacial pain and anxiety comorbidity. Anterior cingulate cortex (ACC) hyperactivation and synaptic dysfunction are identified as central neural mechanisms underlying these pathologies, with chemogenetic inhibition of ACC CaMKII+ neurons effectively reversing ...

JWST Imaging of the Closest Globular Clusters—VI. The Lowest‐Mass Objects in M 4 and the Galactic Bulge

Astronomische Nachrichten, EarlyView.
ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

A novel treatment of biogas digestate waste for biochar production and its adsorption of methylene blue and malachite green in a binary system

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study presents a novel treatment of biogas digestate to produce biochar at processing temperatures of 500–700 °C. The resulting biochar was applied for the simultaneous removal of methylene blue (MB) and malachite green (MG) in a binary system.
