  • A series of FRET-based β-arrestin2 biosensors are used to study the dynamics and conformational changes that occur when β-arrestin2 binds to and dissociates from the β2-adrenergic receptor in living cells; results show that after β-arrestin2 dissociates from the β2-adrenergic receptor, it stays at the cell membrane in an active conformation for a while, indicating that β-arrestin is able to signal in a G-protein-coupled receptor (GPCR)-free state.

  • URu2Si2 is full of mystery. Despite having f-electrons, it is unclear whether heavy electrons are present in the ‘hidden order’ phase. Thanks to photoemission studies, itinerant heavy electrons have been observed just above the hidden-order phase transition, below which the electronic energy spectrum develops a gap.
