Gastrulation movements in all animal embryos start with regulated deformations of patterned epithelial sheets. Current studies of gastrulation use a wide range of model organisms and emphasize either large-scale tissue processes or dynamics of individual cells and cell groups. In … Read More

Microemulsions, mixtures of oil, water, and surfactant, are thermodynamically stable. Unlike conventional emulsions, microemulsions form spontaneously, have a monodisperse droplet size that can be controlled by adjusting the surfactant concentration, and do not degrade with time. To make microemulsions, a … Read More

The idea of using the predictable base pairing of DNA nucleobases for programmable assembly on the nanoscale dates back to the 1980s when the recently deceased Ned Seeman had the idea of using it to crystalize proteins on a DNA-based … Read More

Alphaviruses are a genus of positive-sense single-stranded RNA viruses that infect mammals and are transmitted by mosquitos. These viruses can cause a wide range of diseases, from dengue-like symptoms (e.g., Chikungunya virus) to encephalitis (e.g., Venezuelan Equine Encephalitis virus). While … Read More

Hyperuniformity is an interesting measure of order which detects and quantifies long range positional correlations without requiring local crystalline order. This measure can be defined in real space, through scaling of fluctuations of the number of building blocks in asymptotically … Read More

By exploiting a mapping onto a kinetic Ising-like model we will illuminate the many-body effects underlying the structure, formation, and dissolution of cellular adhesion domains in the presence and absence of external forces. We will present analytical results on the … Read More

We introduce the CP violating scalar leptoquark S3 to explain the measured values of the lepton universality ratios RK(∗). We derive constraints on the CP-even and CP-odd components of the leptoquark Yukawa couplings stemming from effects in b → sμμ and Bs mixing. For the b → sμμ processes we impose RK(∗), B(Bs → μ+μ−), as well … Read More
