An insulin-Myc feed-forward loop triggered by transient JNK boosts transcription of genes essential for mitochondrial respiration and biogenesis during early oogenesis to support massive mtDNA replication and inheritance in Drosophila.
Opioid sensitive neurons were identified using a traceless affinity labeling strategy to covalently label endogenous mu-opioid receptors with fluorescent compounds in living brain slices from wild type animals.
A model of pathogen co-evolving with host population continuously acquiring immunity is used to identify evolutionary parameters allowing pathogen population to persist without going extinct or splitting into independent lineages.
The readiness potential—a long-established neural precursor of voluntary action claimed to precede the onset of the conscious decision to move—is absent, or at least significantly reduced, for deliberate decisions.
The spatial interactions between humans, large carnivores and herbivores cascade down in a complex but predictable way to lower trophic levels affecting regeneration of tree species in a temperate forest.
