Homologous recombination can accurately repair DNA double strand breaks that might otherwise be fatal. It can also combine parts of chromosomes from two parents into one single chromosome, allowing viable offspring to be genetically different from both parents.

Malaria parasites can move at incredible speed. Genetic and biophysical manipulation of the parasites showed how they organize actin filaments into higher order assemblies to achieve fast motility.

Chloroplast division is carried out by a ring containing FtsZ1 and FtsZ2 proteins, which originated from a bacterial tubulin-like protein FtsZ. However, molecular mechanisms of the chloroplast FtsZ ring comprising two types of FtsZs remain unclear. This study demonstrates that FtsZ1 and FtsZ2 can heteropolymerize into a contractible ring in cells of the yeast Pichia pastoris. Our findings suggest that the evolutionary duplication of FtsZ in plants may have increased the mobility and kinetics of...

In addition to favouring traits that enhance organismal fitness, evolution favours selfish gains in replication or transmission. By generating various Drosophila lines with two mitochondrial genotypes, we reveal the impact of selfish selection on how co-residing mitochondrial genomes compete for transmission.

HFSP investigators Gervain and Geffen and colleagues discovered that the newborn human brain is specialized for processing natural sounds. This sensitivity may underlie our ability to perceive and comprehend speech.

Centrioles are microtubule-based eukaryotic structures that build centrosomes and cilia, which are required for accurate cell division and cellular signaling. Centrioles have highly conserved architecture displaying defined numbers and lengths of microtubules. How this occurs has remained unknown and presents an outstanding challenge in biology. Using X-ray crystallography and biochemical and in vivo functional assays, the authors delineated how CPAP regulates delivery of its bound-tubulin to define...

Macromolecular machines for delivery of bacterial effector proteins are a common means of interaction of pathogens with their eukaryotic host but these machines’ structure and function are often ill defined. We have determined the stoichiometry of the complete needle complex of a Salmonella type III secretion system using a combined quantitative proteomics approach to facilitate future functional investigations.

How do sexually dimorphic neuronal connectivity patterns develop? This study demonstrates that synaptic elimination plays a central role in generating sexually dimorphic circuitry using the model organism C. elegans. Within neural circuits shared by both sexes, sex-specific programs drive dimorphic synaptic targeting that rewires the common nervous system for sexually dimorphic behaviours. This is a novel example of the mechanisms underlying sex differences in the development and function of the...

Convergent evolution describes the repeated evolution of particular forms across the tree of life, for example wings in birds and bats or carnivorous pitcher plants in plant families, Sarraceniaceae and Nepenthaceae. But interactions between organisms also evolve independently and repeatedly, for example symbioses between plants and fungi. We name these as convergent interactions, and explore how convergence shapes microbial ecology.

During embryonic development, organs are formed in a process that involves specific interactions among different cell types. In many cases, the cells that make up an organ are motile cells that arrive in the region where the organ develops following a migration process, but the mechanisms by which the motile cells are maintained at the location where they interact with other cells thereby shaping and positioning the organ were unknown. This study reveals that the organ progenitor cells sustain their...
