Title: New Structures in the J/psi J/psi Mass Spectrum at CMS Abstract: The speaker will discuss the new structures reported by the CMS collaboration recently. Three structures are found in the J/psi J/psi mass spectrum in proton-proton collisions at 13 TeV, and a model with quantum interference among these structures provides a good description of […]

Speaker 1: Kurmanbek Kaiyrbekov (from Brian Camley’s group) - Does nematic order allow groups of elongated cells to sense electric fields better? Speaker 2: Aniruddh Murali (from Francesca Serra’s group at SDU) – Cells around corners https://jhubluejays.zoom.us/j/93026415427?pwd=ZGo1ditSNjh6V1JFY2dWNlhTOStLQT09
Interphase Chromatin Undergoes a Local Sol-Gel Transition Upon Cell Differentiation Cell differentiation, the process by which stem cells become specialized cells, is associated with chromatin reorganization inside the cell nucleus. Here, we measure the chromatin distribution and dynamics in embryonic stem cells in vivo before and after differentiation. We find that undifferentiated chromatin is less compact, more […]
Special Condensed Matter Seminar Speaker: Allen Scheie Title: "The old and the new: Probing elemental gadolinium and quantum entanglement with neutron scattering" Abstract: Doing experiments on quantum materials often not nearly as hard as interpreting those experiments. In this talk I discuss two projects where neutron scattering data was analyzed in a new way to […]

Title: Beyond LCDM: New constraints on new components Abstract: Are dark matter and dark energy the only cosmological constituents that lie beyond the Standard Model? It has been suggested that dark matter and dark energy are parts of a more extensive hidden sector that includes additional particles and fields. Since there are no direct observational […]

Emergence of size in living cells The emergence of macroscopic phenomena from interactions of its microscopic components is a problem permeating much of modern physics. Successes include our understanding of phase transitions, while turbulence still remains mostly mysterious. In cell biology, for more than a hundred years, it has been observed that micron-sized structures within […]
