Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics.

This position has an initial appointment of 2 years. Location - This role is hybrid with a mix of remote and in-person work at North Campus Edmonton. About the Role The Dacks Lab is seeking a highly m...

by Christoph — Still images do not tell whether cells rotate their flagella like a propeller or flap them like a whip. To find out, one has to film living cells...

Firmicutes are gram-positive bacteria with important roles in human health, disease, and industry. However, more than a quarter of genes in the mod...

SUMMARYRNA modifications in the tRNA, rRNA, and mRNA constitute a widespread layer of post-transcriptional gene regulation, commonly known as the epitranscriptome. In bacteria, tRNA and rRNA modificat...

In this Perspective, Levin and Wang give a brief history of bacterial growth rate and discuss how it is connected to nutrient availability and macromolecule synthesis, with a focus on (p)ppGpp as a ce...

CRISPR-Cas provides RNA-mediated adaptive immunity, but how its first RNA-guided effector arose is unclear. In this study, we report the discovery of Viral Interference Programmable Repeat (VIPR) syst...

Scientists have discovered a powerful gene-targeting system in viruses. Billions of years old, VIPR seems to predate CRISPR and may be even more effective.

The leaf sheep, a neon green solar-powered slug, has inspired at least one Pokémon character and triumphs in global ballot

The T7 bacteriophage deactivates bacterial defence systems through T7K phosphorylation of nearly all host and phage proteins during infection.

Cell-cell signaling using a core metabolite repurposed as a developmental cue coordinates bacterial multicellular development.

The University of Nevada, Las Vegas (UNLV) appreciates your interest in employment. We ask that you keep in mind the following when completing your application: Once you start the application process ...

Molecular oxygen (O2) is the preferred terminal electron acceptor of the electron transport chain due to its high redox potential and is therefore an essential driver of cellular metabolism in aerobic...

Alt: Literal data about how magnetoreception works

Escherichia coli can survive methylglyoxal stress by modulating phosphorylation of a regulatory phosphotransferase system, which, in turn, regulates the activity of a potassium/proton antiporter. The...

Bacteriophages vary widely in life history strategy, but little is known about how these strategies influence host invasion and inter-phage competition in biofilms. This study explores the abilities o...

Pictures Considered #61 by Christoph — The last thirty years have been an "eye-open­ing" jour­ney for mi­cro­bial cell bio­logists, quite li­ter­al­ly. I am, of course, talk­ing about fluores­cent…

Sequencing of marine sediments finds 136 newly identified Heimdallarchaeia and several novel lineages, and indicates that Heimdallarchaeia evolved distinct metabolic capabilities from other Asgar...
