Detection of Microbial Contaminants in Water: Conventional Methods, Pragmatic Alternatives, and Nanosensing Techniques

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Conventional culture and immunological methods of detecting bacterial water contaminants have some limitations. There are alternative pragmatic methods which are more efficient and faster in the detection of bacteria in water, especially nanosensors. ABSTRACT The complexities of microbial detection and conventional enumeration necessitates the adoption

A Deeply Branching Lineage in Heterolobosea (Discoba) With Multiflagellated and Multigrooved Life Stages

Journal of Eukaryotic Microbiology, Volume 72, Issue 5, September/October 2025.
ABSTRACT Several distantly related, deep‐branching lineages within the eukaryotic tree of life share what is known as the “typical excavate” morphology. This cell architecture includes a suspension‐feeding ventral groove, supported by complex and specific structures of the cytoskeleton, and a vane‐bearing posterior flagellum.

Flavonoids as Promising Akt1 Inhibitors in Cancer Medicine: Insights From Molecular Docking, Dynamics, DFT Calculations, and In Vitro Validation

Cancer Reports, Volume 8, Issue 8, August 2025.
ABSTRACT Background The PI3K/Akt/mTOR signaling pathway is commonly deregulated in different types of cancers, contributing to tumor proliferation, persistence, and resistance to treatment. Akt1, a crucial kinase within this pathway, plays a critical role in tumor progression and the occurrence of therapeutic resistance.

Seasonal Host Shifts for Legionella Within an Industrial Water‐Cooling System

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Taxonomic profiling for Legionella (the causative agent of Legionnaires' disease) and protist hosts within a water cooling tower showed seasonal peaks for Legionella that were associated with taxonomic shifts in the protist community. Legionella frequency was tracked using amplicon sequencing (blue line) and serogroup profiling (red line).
