TL;DR: Simulations reveal that the sequential use of magnetic and chemical cues can potentially provide a robust navigational strategy for locating Ascension Island, consistent with the hypothesis that sea turtles, and perhaps other marine animals, use a multi-modal navigational Strategy for locating remote islands.

TL;DR: Exposure to a strong magnetic pulse altered the orientation behavior of Caribbean spiny lobsters, a finding consistent with the hypothesis that lobsters have magnetoreceptors based on the magnetic mineral magnetite.

TL;DR: RNA sequencing is used to examine gene expression in the brain of rainbow trout after exposure to a magnetic pulse known to disrupt magnetic orientation behaviour, and results are consistent with the hypothesis that a magnetic pulses alters or damages magnetite-based receptors and/or other iron-containing structures, which are subsequently repaired or replaced through processes involving ferritin.

TL;DR: Findings provide additional evidence for magnetoreception in spiny lobsters, raise the possibility of an ontogenetic shift in how lobsters respond to magnetic fields, and suggest that magnetic anomalies might influence lobster movement in the natural environment.

TL;DR: In this article, the authors characterized the sensory gene repertoire and examined the expression profiles of genes linked to vision and chemosensation in two life stages of an insect that goes through metamorphosis, the butterfly Bicyclus anynana.
