"Swimming Strokes of Microorganisms: Collective Motion by Molecular Motors" The beating patterns of sperm flagella and the breast-stroke like swimming strokes of ciliates are driven by the molecular motor dynein. This motor generates sliding forces between adjacent microtubule doublets within the axoneme, the motile cytoskeletal structure. To create regular, oscillatory beating patterns, the activities of the dyneins must be coordinated both spatially and temporally.

The phase diagram of electron-doped pnictides as a function of temperature, electronic density, and isotropic quenched disorder strength obtained by means of computational techniques applied to a three-orbital (xz, yz, xy) spin-fermion model with lattice degrees of freedom will be presented. In experiments, chemical doping introduces disorder but in theoretical studies the relationship between electronic doping and the randomly located dopants, with their associated quenched disorder, is difficult to address.

"Revisiting Decades-Old Physics to Improve Modern Molecular Imaging" Molecular imaging-the use of chemical signatures to image function instead of merely structure-promises to enable a new generation of clinical modalities that can revolutionize both diagnosis and treatment. I will focus on two specific modalities-magnetic resonance and optical imaging-and discuss how a close coupling between basic physics on the one hand, and focused clinical questions on the other hand, enable new and important applications.

Note the unusual weekday! -- Majorana modes in hybrid superconductor-semiconductor nanowire devices can be probed via tunneling spectroscopy which shows a zero bias peak (ZBP) in differential conductance. However, alternative mechanisms such as disorder or formation of quantum dots can also give rise to ZBPs, and obscure experimental studies of Majoranas. Further, a soft induced superconducting gap presents an outstanding challenge for the demonstration of their topological protection.

"Active Matter Builds Life" - Thermodynamic non-equilibrium is a defining feature of living systems on all levels of organization. Cells and tissues are built of "active matter", dynamic materials with built-in force generators. Such materials self-organize in biological systems into well-ordered dynamic steady states, sustained by the dissipation of metabolic energy. The materials show striking collective phenomena on a mesoscopic scale, reminiscent of second order phase transitions and criticality.
