Editors' Summary: This Replication Study has reproduced important parts of the original paper.

A novel high-throughput, whole organism chemical screening platform was used to identify existing drugs that increase pancreatic beta-cell mass in zebrafish, implicating unique roles for the NF-κB and serotonergic signaling pathways in regulating pancreatic biology.

Engagement of both host and parasite signaling pathways proves a novel approach for developing improved anti-parasitic therapies.

By using structural methods to screen compounds for their ability to interact with amyloid beta, researchers have identified small molecules that stabilize amyloid fibers and reduce the toxic effect of smaller aggregates on cells.

Opioid drug efficacy and allosteric modulation is measured using an active state sensor of the mu-opioid receptor.

Detailed structural analysis of NPAS1-ARNT and NPAS3-ARNT complexes, and further comparisons with other bHLH-PAS protein structures, show that this family of mammalian transcription factors have distinct ligand-binding pockets within their molecular architectures.

The structure of human PINK1 explains structural regulation and clarity on the impact of loss of function disease-associated mutations, which may stimulate future drug discovery efforts for both familial and idiopathic Parkinson's disease.
