Behavior- or optogenetic-driven activation of a basolateral amygdala projection to the nucleus accumbens enhances infralimbic cortex activity and long-term fear extinction.
Psychophysical measurement and computational modeling show that sensory information cannot contribute directly to a cognitive judgment, but must first be integrated into resource-limited working memory.

The widespread occurrence of metabolically active streptomycetes in Odontotaenius disjunctus beetle frass may insulate their galleries against pathogenic fungal invasion through the production of diverse antimicrobial specialized metabolites.
The autophagy protein ATG2A tethers membranes and transfers lipids between them, suggesting that autophagosome membranes grow upon the acquisition of lipids from the ER through the ATG2A bridge.
Being fast, memory efficient, easy to use, and with powerful integrated tools, TRex will lower barriers of entry into, and enable more ambitious approaches to, the quantitative study of behavior.

Precisely tracking the anatomical sources of neural computations infers functional directed connectivity between hippocampal memory neurons and cortical sensory neurons, it reveals information flowing from cortex to hippocampus during encoding but the reverse direction during maintenance.
Lower malaria prevalence in females does not appear to be due to lower rates of infection but rather due to faster clearance of asymptomatic infections.
