Water and the Many-Body Imagination
Albert Libchaber, Tsvi Tlusty
An electron crosses the cold Fermi sea. The sea recoils, screens, remembers. It returns the electron dressed: a quasiparticle with a mass, a lifetime, and a Green function. This wa…
Walking droplets, swimming microbes: on memory in physics and life
Albert Libchaber, Tsvi Tlusty
Whirling and swerving, a bacterium is swimming in a test tube, foraging for food. On the surface of a vibrating bath, a droplet starts walking. A certain similarity, but mostly dis…
Green function of correlated genes in a minimal mechanical model of protein evolution
Sandipan Dutta, Jean-Pierre Eckmann, Albert Libchaber +1
The function of proteins arises from cooperative interactions and rearrangements of their amino acids, which exhibit large-scale dynamical modes. Long-range correlations have also…
Localization and dynamics of sulfur-oxidizing microbes in natural sediment
Alexander Petroff, Frank Tejera, Albert Libchaber
Organic material in anoxic sediment represents a globally significant carbon reservoir that acts to stabilize Earth's atmospheric composition. The dynamics by which microbes organi…
Growth and instability of a phospholipid vesicle in a bath of fatty acids
Julien Dervaux, Vincent Noireaux, Albert Libchaber
Using a microfluidic trap, we study the behavior of individual phospholipid vesicles in contact with fatty acids. We show that spontaneous fatty acids insertion inside the bilayer…
Physical model of the genotype-to-phenotype map of proteins
Tsvi Tlusty, Albert Libchaber, Jean-Pierre Eckmann
How DNA is mapped to functional proteins is a basic question of living matter. We introduce and study a physical model of protein evolution which suggests a mechanical basis for th…
Amino Acid Distributions and the Effect of Optimal Growth Temperature
Benjamin Greenbaum, Pradeep Kumar, Albert Libchaber
We perform an exhaustive analysis of genome statistics for organisms, particularly extremophiles, growing in a wide range of physicochemical conditions. Specifically, we demonstrat…
Pressure and temperature dependence of growth and morphology of Escherichia coli: Experiments and Stochastic Model
Pradeep Kumar, Albert Libchaber
We have investigated the growth of Escherichia coli E.coli, a mesophilic bacterium, as a function of pressure and temperature . E.coli can grow and divide in a wide range of…
Universal protein fluctuations in populations of microorganisms
Hanna Salman, Naama Brenner, Chih-kuan Tung +5
The copy number of any protein fluctuates among cells in a population; characterizing and understanding these fluctuations is a fundamental problem in biophysics. We show here that…
Effect of pressure on the kinetics of bulge bases in small RNAs
Pradeep Kumar, J. Lehmann, A. Libchaber
Using molecular dynamics simulations, we study the effect of pressure on the binding propensity of small RNAs by calculating the free energy barrier corresponding to the looped out…
High-Fidelity DNA Sensing by Protein Binding Fluctuations
Tsvi Tlusty, Roy Bar-Ziv, Albert Libchaber
One of the major functions of RecA protein in the cell is to bind single-stranded DNA exposed upon damage, thereby triggering the SOS repair response.We present fluorescence anisot…
Protein-DNA computation by stochastic assembly cascade
Roy Bar-Ziv, Tsvi Tlusty, Albert Libchaber
The assembly of RecA on single-stranded DNA is measured and interpreted as a stochastic finite-state machine that is able to discriminate fine differences between sequences, a basi…
