A neural circuit between the prefrontal cortex and bed nucleus of the stria terminalis is shown to limit fear to cues that only partially associate with threat.
The cotranslational membrane integration of three multispanning Escherichia coli inner membrane proteins is followed using force profile analysis, uncovering unexpected complexities in the membrane integration process.
A series of selective events, each improving fitness relative to an immediate predecessor, can result in organisms that are less fit compared to a distant ancestor.
An ancestral enzyme tailors allocation of essential lipid resources to the progeny and connects maternal and embryonic sterol metabolism for reproductive success.
Leaf-cutting ants use their fecal fluid to vector enzymes produced by their fungal symbiont to degrade plant biomass with a combination of degradation enzymes and Fenton chemistry.
Placing the PACAP/PAC1 signaling within glutamate/GABA cell type and subregional contexts in mouse brain reveals its conspicuous role for sensorimotor circuit interaction through modulating neuronal plasticity.
