Epidemic strains of the bacterium Clostridium difficile have now been found to grow on unusually low levels of the food additive trehalose, providing a possible explanation for C. difficile outbreaks since 2001.
Evidence has now been found that ribosomes — the cell’s translational apparatus — can pass beyond the main protein-coding region of messenger RNAs to form ‘traffic jams’ that inhibit protein expression.
Mice can learn to overcome their naturally aggressive approach to conflict resolution, instead adopting a cooperative strategy. This discovery provides a simple animal model in which to investigate a complex social behaviour.
An approach for the synthesis of E- and Z- trisubstituted alkenes in high stereoisomeric purity is developed by merging catalytic cross-metathesis and cross-coupling processes.
Modelling the reactions of water with the crusts of early Earth and Mars sheds light on how water was transported through their crusts to give the surfaces we see today.
