Critical fluctuations in plasma membrane vesicles.
We demonstrate critical behavior in giant plasma membrane vesicles (GPMVs) that are isolated directly from living cells. GPMVs contain two liquid phases at low temperatures and one liquid phase atExpand

Line tensions, correlation lengths, and critical exponents in lipid membranes near critical points.
Membranes containing a wide variety of ternary mixtures of high chain-melting temperature lipids, low chain-melting temperature lipids, and cholesterol undergo lateral phase separation intoExpand

Inflammasome activation causes dual recruitment of NLRC4 and NLRP3 to the same macromolecular complex
Significance The nucleotide-binding oligomerization domain-like receptor (NLR) family members, NLRC4 and NLRP3, activate the inflammasome to provide host defenses against infection. The preciseExpand

Diffusion of liquid domains in lipid bilayer membranes.
We report diffusion coefficients of micron-scale liquid domains in giant unilamellar vesicles of phospholipids and cholesterol. The trajectory of each domain is tracked, and the mean squareExpand

Short-time movement of E. coli chromosomal loci depends on coordinate and subcellular localization.
In bacteria, chromosomal architecture shows strong spatial and temporal organization, and regulates key cellular functions, such as transcription. Tracking the motion of chromosomal loci at shortExpand

The nonlinear mechanical response of the red blood cell.
We measure the dynamical mechanical properties of human red blood cells. A single cell response is measured with optical tweezers. We investigate both the stress relaxation following a fastExpand

Direct exchange of vitamin B12 is demonstrated by modelling the growth dynamics of algal–bacterial cocultures
The growth dynamics of populations of interacting species in the aquatic environment is of great importance, both for understanding natural ecosystems and in efforts to cultivate these organisms forExpand

Red blood cell dynamics: from spontaneous fluctuations to non-linear response
We studied experimentally the mechanical properties of the red blood cell. By attaching beads biochemically on the cell membrane at diametrically opposite positions, the membrane movements can beExpand

The role of mechanical forces in the planar-to-bulk transition in growing Escherichia coli microcolonies
Mechanical forces are obviously important in the assembly of three-dimensional multicellular structures, but their detailed role is often unclear. We have used growing microcolonies of the bacteriumExpand

Persistent super-diffusive motion of Escherichia coli chromosomal loci.
The physical nature of the bacterial chromosome has important implications for its function. Using high-resolution dynamic tracking, we observe the existence of rare but ubiquitous 'rapid movements'Expand
