Endocytosis gets squeezed

Flow to the front ortical actomyosin flow carries polarity proteins to the front of the worm embryo, according to Edwin Munro (Center for Cell Dynamics, Friday Harbor, WA), Jeremy Nance, and James Priess (Fred Hutchinson Cancer Research Center, Seattle, WA). Similar flows may set up polarity in many other systems. The idea that asymmetrical contraction drives cortical flow and the segregation o...

Endocytosis gets in tune with action potential bursts

Neurons use a calcium-dependent mechanism to optimize the rate at which synaptic vesicles are recycled.

Squeezed light from spin-squeezed atoms.

We propose to transfer quantum correlations from atoms to light by Raman scattering of a strong laser pulse on a spin-squeezed atomic sample. We prove that the emission is restricted to a single field mode which perfectly inherits the quantum correlations of the atomic system.

Squeezed Condensates

We analyse the atomic state obtained by photo-dissociation of a molecular Bose-Einsteincondensate. This process is equivalent to down-conversion in quantum optics where it is responsible for squeezing of the field amplitudes. Monte Carlo simulations derived from the Positive P description of the system, and approximate equations for second moments of the atomic field operators are introduced to...
