Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

From mother tongue to English: A language policy shift at a multilingual township school in Gauteng
South African Journal of Childhood EducationBackground: Given the lack of research into English language instruction in multilingual contexts, this study explored the switch from mother tongue to English in a South African township school. Aim: This study aims to find out how teachers and parents

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Phase Relativity as a Foundation of Spacetime from the Quantum Phase
We present a model in which spacetime is not assumed as primitive, but is recovered from conserved relational phase. The sole kinematic postulate is that each physical process carries a dimensionless recurrence count that partitions into internal recurrence and external propagation.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

A radical new approach or a discursive battleground? Making sense of the Foundation Phase for Wales
, 2013 The Foundation Phase for Wales, drawing, in part, on ‘excellent’ early years programmes in Scandinavia, New Zealand and Reggio Emilia, has been heralded as a radical new approach to early years education within the UK. Reflecting concerns about the early
