TL;DR: Results indicate that enkephalin-mimetic delta opioid agonists are capable of producing non-photic phase shifts in hamster activity rhythms, and that opioids can independently affect circadian phase and activity levels in hamsters.

TL;DR: It is shown that SNC 80, an agonist for the δ opioid receptor subtype, will phase advance hamster wheel running activity rhythms when administered late in the subjective day, indicating that opioids may be involved in modulating the circadian pacemaker in hamsters.
Abstract: Non-photic stimuli administered to hamsters during the subjective day can cause phase advances in circadian wheel running activity. It is believed that afferent projections from the intergeniculate leaflet of the thalamus to circadian pacemaker cells within the suprachiasmatic nucleus mediate the phase shifting effects of some non-photic stimuli. In hamsters, many of the intergeniculate leaflet afferents contain enkephalin, yet the role of opioids in producing non-photic phase shifts in hamsters has not been reported. In the present study, we show that SNC 80, an agonist for the delta opioid receptor subtype, will phase advance hamster wheel running activity rhythms when administered late in the subjective day. These results indicate that opioids may be involved in modulating the circadian pacemaker in hamsters.

TL;DR: A water-filled hamster wheel with glass windows now enables detailed microscopic lab observations of individual aquatic microorganisms during their vertical migrations.
Abstract: Plankton regularly travel vast distances up and down in the ocean. A water-filled hamster wheel with glass windows now enables detailed microscopic lab observations of individual aquatic microorganisms during their vertical migrations.
