Presynaptic temporal dynamics flexibly set input weights in the mouse escape circuit

20. May 2026 by a3-admin

Animals facing threat must integrate multiple streams of information – about danger, environment, and internal state – into a time-pressured escape decision. In mice, this computation is performed by…

Informational blueprints reveal condition-dependent gene regulatory architectures

20. May 2026 by a3-admin

While coding regions in the genome have a direct interpretation in terms of protein products, significant fractions are non-coding and yet control essential biological functions. Unlike the genetic…

The CK2 and DBT kinases promote temperature compensation of the Drosophila circadian clock via distinct pathways

20. May 2026 by a3-admin

Circadian (~24 h) rhythms are essential for the survival of most organisms, as they optimize physiology and behavior with the time of day. They are defined by three fundamental properties: they are…

Occupationally Relevant Wildfire Smoke Inhalation Impairs Nitric Oxide Signaling and Promotes Progressive Aortic Stiffening in Hypercholesterolemic Mice

20. May 2026 by a3-admin

Background. Wildland firefighters experience repeated occupational exposure to wildfire smoke at high particulate matter (PM) concentrations, leading to elevated cardiovascular disease risk and…

The high-quality genome assembly of Coelioxoides waltheriae (Apidae: Nomadinae) reveals gene family dynamics and evolutionary shifts related to its cleptoparasitic lifestyle

20. May 2026 by a3-admin

Cleptoparasitism, or brood parasitism, is a striking behavioral strategy observed in approximately 13% of all bee species, yet its genomic underpinnings remain largely unexplored. We present the…

Incomplete letter recognition is limited by cortical and not optical factors: Simulating the visual deficits of dementia in healthy adults

20. May 2026 by a3-admin

Incomplete letter recognition tasks are frequently used to detect visual deficits arising from neurodegenerative syndromes, including Posterior Cortical Atrophy (PCA; ‘visual-variant Alzheimer’s…

A Liver-Targeted Copper Supplement Reduces Metabolic Dysfunction-Associated Liver Steatosis by Increasing Lipolysis and Fatty Acid Oxidation

20. May 2026 by a3-admin

Abstract: Metabolic-associated steatotic liver disease (MASLD) is a prevalent liver disease driven by complex dysregulation of hepatic lipid metabolism. Here we show that copper deficiency is a…

MTDH-SND1 disruption sensitizes ovarian cancer to ferroptosis and PARP inhibition

20. May 2026 by a3-admin

BRCA-deficient high-grade serous ovarian cancer is characterized by profound genomic instability and elevated replication-associated DNA damage, rendering these tumors initially sensitive to…

Twitchin kinase, a mechanoreceptor in the muscle sarcomere, is a catalytically-primed moonlighting kinase

20. May 2026 by a3-admin

To explore conserved mechanisms and functions across mechanosensory kinases associated with the skeletal architectures of the cell, we investigated in vitro and in vivo the substrate targeting of…

Falafel-Style Wrapping of AuNPs for DNA Origami Barcodes

20. May 2026 by a3-admin

The ability to encode and reliably read nanoscale information is increasingly important for multiplexed biomolecular detection and super-resolution imaging. DNA origami provides a uniquely…
