Cory Dean, PhD (Columbia University) – Cory Dean kicked off a revolution in experimental physics. Working with a unique class of two-dimensional materials called van der Waals (vdW) heterostructure materials—very thin materials made of single atomic layers stacked and held together by weak forces—Dean’s breakthrough experimental techniques sparked a completely new field of study known as “twistronics”.

Scientists from the international XENON collaboration announced today that data from their XENON1T, the world's most sensitive dark matter experiment, show a surprising excess of events. The scientists do not claim to have found dark matter. Instead, they say to have observed an unexpected rate of events, the source of which is not yet fully understood.
