The membrane origin of an autophagosome has been a mystery since its discovery more than fifty years ago. A functional and systematic approach reveals that the ER-Golgi intermediate compartment, a sorting organelle between the ER and Golgi, is the source of membranes for nascent autophagosomes.

Patchiness in the distribution of tiny plants known as phytoplankton promotes many important ecological interactions in the marine food web. Our study reveals that turbulent fluid motion, normally synonymous with mixing, triggers intense small-scale patchiness in the distribution of motile phytoplankton.

The human body has hundreds of different cell types, all with the same basic DNA, and all of which can ultimately be traced back to identical stem cells. Despite this fundamental similarity, a bone cell has little in common with a brain cell when it comes to appearance or function. The fact that bone is rigid and mechanically distinct from soft fat or brain had been speculated to play some role in differentiation to new cells in those parts of the body, but mechanisms have been unclear.

Insertion of “designer” genes into specific locations within a bacterial genome allows these genes to be stably maintained without antibiotic selection, and can avoid other difficulties, such as toxicity, often associated with the use of multicopy plasmids. We have created a set of DNA vectors which improve the speed and efficiency of integration into the Escherichia coli genome, allowing for rapid development of genetically engineered strains.

For the first time, scientists have obtained direct electrical recordings of dendrites processing visual information in awake mammals. They found that dendrites are far from passive wiring—they actively compute to support sensory processing.

Researchers are discovering new genetic determinants of disease by correlating variations in our DNA with disease outcomes. In studies of three chronic autoimmune disorders—rheumatoid arthritis, type 1 diabetes and Crohn’s disease—we demonstrate how incorporating knowledge of co-ordinated networks of genes, encoded in online databases, can inform statistical tests for correlation, and generate stronger support for links between genes and predisposition to disease.

Sensory perception in the inner ear relies on proper shaping of the brush of movement detectors at the surface of hair cells, the stereocilia bundle. In this work, we implicate a group of proteins classically regulating mitotic spindle orientation in the partition of the hair cell apical membrane. This blueprint guides cytoskeletal asymmetry, defining in particular the edge of the V-shaped stereocilia bundle.

We performed a series of unbiased in vivo screens of ~16,000 mouse genes, designed to identify candidates based on their potential to elicit a quantitative effect on epidermal growth during embryogenesis and oncogenic hyperplasia. By conducting our studies in the dynamic environment of the physiological system, we uncover many previously overlooked candidates in addition to the well-known growth regulators.

The COPII proteins form a coat responsible for vesicular trafficking of newly synthesized cargo proteins from the Endoplasmic Reticulum. The coat must be flexible to allow incorporation of cargoes of very different shapes and sizes. Using cryo-electron tomography and sub-tomogram averaging on a reconstituted vesicle budding reaction we show that an inner coat layer can assemble in patches of regular protein arrays, and an outer coat layer can form cages with spherical or tubular curvatures by following...

A cell-free extract system was developed to reconstitute actin cable assembly, resulting in identification of a parts list for actin cable proteins. The reconstitution, combined with a super-resolution microscopy analysis, determined that actin cable assembly is regulated in a cell cycle-dependent manner.
