Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Molecular identification and phylogeny of Neritaá¾½s species on rocky shores of the Northern Persian Gulf

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2016
Neritas are among the most dominant groups of Gastropoda in the Persian Gulf. There is no previous study in relation to molecular and phylogeny of Neritas in the study area.

Selaginella dianzhongensis (Selaginellaceae), a new spikemoss from China [PDF]

PhytoKeys, 2019
A new species of spikemoss from Yunnan Province of China, Selaginella dianzhongensis, is described and illustrated based on evidence from gross morphology, micromorphology and molecular phylogeny. S. dianzhongensis is most similar to S.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Reconstruction of Ancient Molecular Phylogeny

Molecular Phylogenetics and Evolution, 1996
Support for contradictory phylogenies is often obtained when molecular sequence data from different genes is used to reconstruct phylogenetic histories. Contradictory phylogenies can result from many data anomalies including unrecognized paralogy.

An updated phylogeny of the family Stenasellidae (Crustacea, Isopoda), with a new species of Stenasellus from southern Vietnam [PDF]

Subterranean Biology
Our current understanding of the molecular systematics of Stenasellidae, a species-rich family of obligate groundwater isopods known from Africa, Asia, Europe and North-America, is based primarily on specimens of the genus Stenasellus Dollfus, 1897 ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Molecular phylogeny: reconstructing the forest

Comptes Rendus. Biologies, 2008
Phylogeny, be it morphological or molecular, has long tried to explain the extant biodiversity by the Tree of Species, which is a logical consequence of strict Darwinian evolutionary principles. Through constant improvement of both methods and data sets, some parts of this diversity have actually been demonstrated to be the result of a tree-like ...

High Rate of Protein Coding Sequence Evolution and Species Diversification in the Lycaenids

Frontiers in Ecology and Evolution, 2017
Understanding the variations in the rate of molecular evolution among lineages may provide clues on the processes that molded extant biodiversity.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
