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…
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…
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…
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…
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…
