The electronic properties of materials are typically determined by their structure under normal, undisturbed conditions, when they are in a state known as equilibrium. Intense light beams, however, can temporarily reshape a material's electronic band structure (i.e., the range of energy states available to electrons), potentially giving rise to new electronic behaviors.
Archaeologists uncover rock-cut tombs and Roman military remains at Tell el-Yahudiya, an ancient Egyptian site with a remarkable connection to Jewish history.
Cells rely on complex signaling networks in which different molecular pathways communicate with one another. Small GTPases act as molecular switches in these networks, controlling diverse cellular…
