SUMMARY:Ekaterina Poliukhina\, "Direct measurement of protein-protein interaction potentials by cryo-electron tomography"
DESCRIPTION:Protein-protein interactions control how proteins behave in solution\, dictating aggregation\, crystallization\, phase separation\, and the colloidal stability of formulations central to pharmacology\, food science\, and biotechnology. Predicting this behavior has long been difficult: theories borrowed from classical colloid science fail for proteins\, which are irregularly shaped and chemically heterogeneous\, and no direct experimental route to the underlying interaction potential has been available. Cryo-electron tomography now provides such a route. By reconstructing three-dimensional tomograms containing thousands of individual proteins\, the spatial distribution of every particle can be recovered and converted\, without any assumed functional form\, into a measured interaction potential. Validated against analytical ultracentrifugation and small-angle X-ray scattering\, the approach spans globular proteins from lysozyme to apoferritin and reveals how ionic strength\, pH\, temperature\, and additives reshape their interactions.\nhttps://indico.ijs.si/event/3599/

SUMMARY:Maximilian Bachmaier: The slingshot effect and its cosmological implications
DESCRIPTION:In my talk\, I will present the so-called slingshot effect. It represents a general phenomenon that occurs when a localized source\, such as a magnetic monopole\, quark\, or a D-brane\, crosses a wall separating the confined (Higgsed) and unconfined (Coulomb) phases. The crossover is accompanied by a stretched string that confines the source to the wall. The string tension accelerates the source towards the wall as sort of a slingshot. The effect can take place in different setups\, such as phase transitions leading to both electric and magnetic confinement\, as well as in string cosmology involving D-branes. I will discuss the role of this phenomenon in sourcing gravitational waves. \nhttps://indico.ijs.si/event/3895/
