A circalunar oscillator and moonlight tune the circadian clock to moon phase via cwo/Dec1

This study identifies cwo/Dec1 as a molecular mechanism linking the circadian clock to lunar phase in Platynereis dumerilii, showing its role in circalunar oscillation.

PER2- and state-dependent transcriptional programs gate neural stem cell proliferation with niche-specific circadian autonomy

The paper shows PER2-dependent circadian regulation of adult neural stem cell proliferation in two niches, with SVZ requiring external stimuli for synchronization.

Cryopreservation of Platynereis dumerilii larvae

This paper develops a cryopreservation protocol for Platynereis dumerilii larvae, achieving 34% survival after 5 months with a specific cooling and thawing regimen.

Peripheral tissues of deep-sea mussels exhibit autonomous circadian timing via an atypical mechanism

This study identifies an endogenous circadian clock in deep-sea mussels that generates both tidal and circadian rhythms through an atypical mechanism.

A cryptochrome photoreceptor controls animal light-dependent growth and lifespan via evolutionary conserved hormonal pathways

This study shows that cryptochrome loss in marine bristleworms increases lifespan and size, with hormonal pathways linked to sexual development and reproduction.

A c-opsin functions in a ciliary-marginal zone-like stem cell region of an invertebrate camera-type eye

The paper identifies neural stem cells in the adult eye of Platynereis dumerilii that express c-opsin1 and show proliferation patterns similar to vertebrate ciliary marginal zone stem cells.

A fast and versatile method for simultaneous HCR, immunohistochemistry and EdU labeling (SHInE)

The paper introduces a method for simultaneous HCR, immunohistochemistry, and EdU labeling to analyze gene expression, protein localization, and cell proliferation in complex tissues.

A Cryptochrome adopts distinct moon- and sunlight states and functions as moonlight interpreter in monthly oscillator entrainment

This paper identifies L-Cryptochrome as a moonlight interpreter that distinguishes between sun- and moonlight to regulate monthly oscillator entrainment in Platynereis dumerilii.

Two light sensors decode moonlight versus sunlight to adjust a plastic circadian/circalunidian clock to moon phase

The paper identifies two light sensors in Platynereis dumerilii that distinguish moonlight from sunlight to adjust a circadian clock to moon phase.

Analyses of cephalic and non-cephalic sensory cell types provide insight into joint photo- and mechanoreceptor evolution

The paper analyzes sensory cell types in Platynereis dumerilii to explore the evolutionary relationship between photo- and mechanoreceptors, finding that r-Opsin1 modulates mechanosensation through light-dependent mechanisms.

TMT-Opsins differentially modulate medaka brain function in a context-dependent fashion

This paper investigates how TMT-opsins modulate medaka brain function differently in various contexts, revealing non-additive interactions and behavioral impacts.

Ciliary and rhabdomeric photoreceptor-cell circuits form a spectral depth gauge in marine zooplankton

The paper shows ciliary and rhabdomeric photoreceptors in Platynereis larvae functionally integrate to determine vertical swimming direction based on light ratios, acting as a depth gauge.
