For decades physicists have sought signs of misbehaving particles—evidence of subtle cracks in the "Standard Model" of particle physics, the dominant theory describing the most fundamental building ...

The process by which sheared suspensions go through a dramatic change in viscosity is known as discontinuous shear thickening. Although well-characterized on the macroscale, the microscopic mechanisms ...

Dipangkar Dutta receives funding from US Dept. of Energy and NSF. A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic particles. What ...
