DNA barcodes reveal population-dependent cryptic diversity and various cases of sympatry of Korean leptonetid spiders (Araneae: Leptonetidae)

open access: yesScientific Reports, 2022
Leptonetidae are tiny, rarely encountered spiders that mainly inhabit moist environments, such as caves, leaf litter, and rock piles. Because they are microhabitat specialists, most leptonetid species have short-range endemism, and rarely occur in ...

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

open access: yesAging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Phylogenetic Insights on Patterns of HIV-1 Spread and the Design of Epidemic Control Measures

open access: yesViruses, 2022
Phylogenetics provides a unique structural framework to track the spread of viral diseases, such as HIV-1 (human immunodeficiency virus type 1), the causative agent of AIDS (acquired immunodeficiency syndrome) [...]

UTact: Underwater Vision‐Based Tactile Sensor with Geometry Reconstruction and Contact Force Estimation

open access: yesAdvanced Robotics Research, EarlyView.
Embedded flexible sensing technologies advance underwater soft robotics, yet most systems still suffer from hysteresis and limited perceptiveness. Instead, vision‐based tactile sensors provide reliable and rapid feedback essential for complex underwater tasks.

Practice-oriented controversies and borrowed epistemic credibility in current evolutionary biology: phylogeography as a case study [PDF]

open access: yes, 2013
Although there is increasing recognition that theory and practice in science are intimately intertwined, philosophy of science perspectives on scientific controversies have been historically focused on theory rather than practice.

Cold Orthogonal Translation: A Psychrophilic Pyrrolysyl‐tRNA Synthetase Boosts Genetic Code Expansion in E. coli

open access: yesAdvanced Science, EarlyView.
ABSTRACT Orthogonal translation systems (OTSs) enable site‐specific incorporation of non‐canonical amino acids (ncAAs) and are central to genetic code expansion. Current engineering strategies typically rely on hyperstable aminoacyl tRNA synthetase (aaRS) scaffolds to tolerate destabilizing mutations required for substrate diversification.

Is it time to abandon the flow cytometry in estimations of genome size when the K-mer analysis is available? The case of Engelhardia species

open access: yesGenomics Communications
Genome size represents a fundamental genomic trait with profound implications across evolutionary biology, ecology, and genomics. Flow cytometry (FCM) has served as the gold standard for estimating genome size for decades, while the advent of next ...

Modeling DNA methylation dynamics with approaches from phylogenetics [PDF]

open access: yes, 2014
Methylation of CpG dinucleotides is a prevalent epigenetic modification that is required for proper development in vertebrates, and changes in CpG methylation are essential to cellular differentiation.

Functional Analysis of Ligand‐Gated Chloride Channels in a Cnidarian Sheds Light on the Evolution of Inhibitory Signaling

open access: yesAdvanced Science, EarlyView.
We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

Modeling the Ecology and Evolution of Biodiversity: Introduction to the Special Issue

open access: yesDiversity, 2022
Applying relevant statistical models to empirical data analysis has been considered a very important procedure for scientists to answer research questions in the fields of biodiversity, phylogeography, evolutionary biology, paleoecology, phylogenetics ...
