Neutrons study a number of hot topics from the field of particle physics and cosmology: Recent measurements of various mixed American-British-French-GermanHungarian-Japan-Russian groups of researchers determine the strength of the weak interaction of the neutron, which gives us unique information on quark-mixing and the question of unitarity. Much to our surprise, with neutron-decay we find a d...

In this talk we review the physics of top-quark mass generation in models of dynamical electroweak symmetry breaking and the constraints on this physics arising from limits on the deviation of the weak interaction ρ-parameter from one. We then discuss top-color assisted technicolor in this context. 1. mt in Models of Dynamical Electroweak Symmetry Breaking In technicolor models, the masses of t...

We review the compelling case for establishing a capability to accelerate positrons at Jefferson Lab. The potential appplications range from the study of two-photon exchange and deeplyvirtual Compton scattering to exploiting the charge current weak interaction to probe the flavor structure of hadrons and nuclei. There are also fascinating ideas for using such a capability to discover new physic...

Extreme ultraviolet frequency combs are a versatile tool with applications including precision measurement, strong-field physics, and solid-state physics. Here we report on an application of extreme ultraviolet frequency combs and their driving lasers for studying strong-field effects in molecular systems. We perform field-free molecular alignment and high-order harmonic generation with aligned...

Molecular docking is a computational chemistry method which has become essential for the rational drug design process. In this context, it has had great impact as a successful tool for the study of ligand-receptor interaction modes, and for the exploration of large chemical datasets through virtual screening experiments. Despite their unquestionable merits, docking methods are not reliable for ...

Biology and physics share common ancestors. The progress of methods of statistical physics and the developments of new physical tools and various ingenious experimental techniques have triggered dramatic progress for the field of biophysics. Likewise, the two fields fertilized each other repeatedly over the last decades. Most import antly, the complexity of biophysics inspired new developments ...
