Fight or die? How prokaryotes deal with infections
In their review in BioEssays, Eugene Koonin and Feng Zhang discuss the different outcomes when prokaryotes are infected by a virus.
How sterile workers still manage to pass on “their” genes and evolve!
In their hypothesis article in BioEssays, Downing et al. present a testable hypothesis as to why sterile worker castes evolve, and continue to evolve, in many social insect orders: a hypothesis with implications for understanding longevity in general.
Obese flies: Why are adipokinetic hormone-deficient flies fat?
The adipokinetic hormone (AKH), an insect analog of the human hormone glucagon, is a central regulator of energy homeostasis and lipid mobilization in insects. Silencing of the AKH-receptor leads to fly obesity.
Active DNA demethylation: A two-step process
Matthias Bochtler et al. discuss the current state of knowledge surrounding active DNA demethylation pathways.
How fat cells become fat: Insights from phosphoproteomics
Fat is stored in adipocytes in the adipose tissue. In addition, the tissue contains other cell types including fibroblasts, vascular endothelial cells, immune cells and preadipocytes.
Genes evolving in parallel to produce the same traits – less of a mystery
In their review in BioEssays, Bailey et al. present a model of a process that occurs more often than we’d suspect: identical genetic changes in evolutionarily unrelated populations.
Beyond the DNA — comprehensive map of the human epigenome completed
Scientists have established comprehensive maps of the human epigenome, shedding light on how the body regulates which genes are active in which cells.
Sub 2-nm solid-state nanopores: smaller pores can see more
A team from the University of Ottawa, Canada have automatically fabricated 2-nm solid-state nanopores with high yield.
Molecular motor can walk nanoparticles along nanotubes
Researchers have created a new type of molecular motor made of DNA and used it it to transport a nanoparticle along the length of a carbon nanotube.
