We introduce strong tailored light-wave-driven time-reversal symmetry breaking in monolayer hexagonal boron nitride, realizing a sub-laser-cycle controllable analogue of the topological model of Haldane and inducing non-resonant valley polarization.
A pioneering ‘connectomics’ collaboration has successfully reconstructed one cubic millimetre of brain tissue, but researchers are still just scratching the surface of the complexity it contains.
Researchers from the global south face often-distressing immigration bureaucracy that most from the global north do not. Six steps can begin to counteract this inequity.
A crystal structure predicted by Eugene Wigner in 1934 has been directly imaged for the first time. Plus, the first algae that can fix nitrogen and evidence for a shared practice of human sacrifice across Stone Age Europe.
