New discovery speeds scientists" push for Huanglongbing-tolerant citrus
It's one thing for a hybrid citrus tree to tolerate citrus greening disease (a.k.a. Huanglongbing) and quite another if it also produces orange-like fruit—especially if the juice makes for a delicious breakfast beverage. Now, that holy grail of tra.....»»
Physicists discover a quantum state with a new type of emergent particles: Six-flux composite fermions
If the fractional quantum Hall regime were a series of highways, these highways would have either two or four lanes. The flow of the two-flux or four-flux composite fermions, like automobiles in this two- to four-flux composite fermion traffic scenar.....»»
