The paper investigates how Botrytis cinerea interacts with abaxial and adaxial leaf surfaces across multiple plant species, finding that abaxial surfaces are more susceptible and linking this to defense signaling and compound production.

Acanthella acuta Mitochondrial DNA: Linear Architecture and Other Unique Features

This paper describes the unique linear mitochondrial DNA architecture of Acanthella acuta, including inverted terminal repeats, group II introns, and novel ORFs, and suggests horizontal transfer for some features.

Restoring adiponectin via rosiglitazone ameliorates tissue wasting in mice with lung cancer.

This study shows that rosiglitazone restores adiponectin levels and preserves tissue mass in mice with lung cancer by enhancing AMPK and AKT activity.

Identification of 30 transition fibre proteins reveals a complex and dynamic structure with essential roles in ciliogenesis

The paper identifies 30 new transition fibre proteins in Trypanosoma brucei and shows their dynamic roles in ciliogenesis and flagellum length regulation.

A Deep Dive into the SARS-Cov-2 Polymerase Assembly: Identifying Novel Allosteric Sites and Analyzing the Hydrogen Bond Networks and Correlated Dynamics

This paper analyzes the SARS-CoV-2 polymerase structure and dynamics to identify novel allosteric sites and hydrogen bond networks, suggesting potential targets for antiviral drugs.

Occurrence and Antimicrobial Resistance Pattern of E. coli O157:H7 Isolated from Foods of Bovine Origin in Dessie and Kombolcha Towns, Ethiopia

Long Noncoding RNA MALAT1 is Dynamically Regulated in Leader Cells during Collective Cancer Invasion

The paper shows MALAT1 lncRNA is dynamically regulated in leader cells during collective cancer invasion, with its expression increasing when cells become leaders and decreasing when migration stops.

Physical confinement promotes mesenchymal trans-differentiation of invading transformed cells in vivo

The paper shows that mechanical confinement drives mesenchymal trans-differentiation of invasive KRasV12-transformed cells in zebrafish, contributing to metastasis.

Abdominal movements in insect flight reshape the role of non-aerodynamic structures for flight maneuverability I: Model predictive control for flower tracking

This study shows that abdominal movements in hawkmoths contribute to flight maneuverability by using model predictive control and experimental tests.

Mycobacterium tuberculosis senses host Interferon- gamma via the membrane protein MmpL10

This study shows Mycobacterium tuberculosis senses IFN-γ via MmpL10, increasing respiration and virulence, and enhances INH efficacy against persistent bacteria.

Intratumoral Heterogeneity Promotes Collective Cancer Invasion Through NOTCH1 Variation

The paper shows that NOTCH1 variation within microtumors enhances invasiveness, linking intratumoral heterogeneity to collective cancer invasion.

A high-carbohydrate diet prolongs dysbiosis and Clostridioides difficile carriage and increases late-onset CDI and mortality in a hamster model of infection

This study shows a high-carbohydrate diet worsens Clostridioides difficile infection in hamsters by causing prolonged dysbiosis, persistent carriage, and higher mortality compared to a standard diet.

Linking rhizosphere processes across scales: Opinion

The paper discusses how multi-scale rhizosphere processes influence plant-scale behavior and presents models that integrate experimental data across scales to predict rhizodeposition and microbial activity.

Myeloid cell interferon responses correlate with clearance of SARS-CoV-2

This study uses longitudinal single-cell RNA sequencing in rhesus macaques to show that myeloid cell interferon responses correlate with SARS-CoV-2 clearance.
