Hybridization can result in reproductively isolated and phenotypically distinct lineages that evolve as independent hybrid species. How frequently hybridization leads to speciation remains largely unknown. Here we examine the potential recurrence of hybr
Activation of NMDA receptors (NMDARs) within the CNS represents a major signal for persistent alterations in glutamatergic signaling, such as long-term potentiation (LTP) and long-term depression. NMDARs are composed of a combination of NR1 and NR2 subunits, with distinct NR2 subunits imparting...
Preeclampsia is a serious complication of pregnancy, affecting both maternal and fetal health. In genome-wide association meta-analysis of European and Central Asian mothers, we identify sequence variants that associate with preeclampsia in the maternal
