Star formation in evolving molecular clouds

, 2017
Molecular clouds are the principle stellar nurseries of our universe, keeping them in the focus of both observational and theoretical studies. From observations, some of the key properties of molecular clouds are well known but many questions regarding ...

Experimental increase of worker diversity benefits brood production in ants

BMC Ecology and Evolution, 2021
Background The reproductive division of labor of eusocial insects, whereby one or several queens monopolize reproduction, evolved in a context of high genetic relatedness.

BEAST: Bayesian evolutionary analysis by sampling trees [PDF]

, 2007
Background The evolutionary analysis of molecular sequence variation is a statistical enterprise. This is reflected in the increased use of probabilistic models for phylogenetic inference, multiple sequence alignment, and molecular population genetics ...

Point of sampling detection of Zika virus within a multiplexed kit capable of detecting dengue and chikungunya

BMC Infectious Diseases, 2017
Background Zika, dengue, and chikungunya are three mosquito-borne viruses having overlapping transmission vectors. They cause diseases having similar symptoms in human patients, but requiring different immediate management steps.

The Subcellular Proteome of a Planctomycetes Bacterium Shows That Newly Evolved Proteins Have Distinct Fractionation Patterns

Frontiers in Microbiology, 2021
The Planctomycetes bacteria have unique cell architectures with heavily invaginated membranes as confirmed by three-dimensional models reconstructed from FIB-SEM images of Tuwongella immobilis and Gemmata obscuriglobus.

The Global Evolution of Giant Molecular Clouds II: The Role of Accretion [PDF]

, 2011
We present virial models for the global evolution of giant molecular clouds. Focusing on the presence of an accretion flow, and accounting for the amount of mass, momentum, and energy supplied by accretion and star formation feedback, we are able to ...

FoxO1 signaling in B cell malignancies and its therapeutic targeting

FEBS Letters, EarlyView.
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

Enzyme-assisted high throughput sequencing of an expanded genetic alphabet at single base resolution

Nature Communications
With just four building blocks, low sequence information density, few functional groups, poor control over folding, and difficulties in forming compact folds, natural DNA and RNA have been disappointing platforms from which to evolve receptors, ligands ...

Bacterial N4-methylcytosine as an epigenetic mark in eukaryotic DNA

Nature Communications, 2022
Eukaryotic DNA can be methylated as 5-methylcytosine and N6-methyladenine, but whether other forms of DNA methylation occur has been controversial. Here the authors show that a bacterial DNA methyltransferase was acquired >60 Mya in bdelloid rotifers ...
