Controlling microalgae populations by phototactic memory
Gianni Jacucci, Davide Breoni, Pierre Illien +4
Understanding how microorganisms navigate in complex environments is a central question in active matter and biological physics. Phototaxis - the ability to use light as a navigati…
Torque determination on DNA with magnetic tweezers
Francesco Mosconi, Jean-François Allemand, David Bensimon +1
We deduced the torque applied on a single stretched and twisted DNA by integrating with respect to force the change in the molecule's extension as it is coiled. While consistent wi…
Structural plasticity of single chromatin fibers revealed by torsional manipulation
Aurelien Bancaud, Natalia Conde e Silva, Maria Barbi +8
Magnetic tweezers are used to study the mechanical response under torsion of single nucleosome arrays reconstituted on tandem repeats of 5S positioning sequences. Regular arrays ar…
