Applying the Ecological Trap Concept to Cetaceans

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Wild animals may select poor‐quality habitats due to mismatches between perceived and actual habitat quality, creating ecological traps. Although well explored in terrestrial systems, this concept remains underutilized for marine species.

Harvesting the Spin–Orbit Interaction of Light to Generate Helicity‐Dependent Complex Rotational Motion in Optically Trapped Mesoscopic Matter

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
Spin–orbit interaction (SOI) of light is exploited to generate helicity‐dependent complex rotational and revolution dynamics in optical tweezers. At the trap center, particle rotation is governed by the direct helicity that follows the input polarization.
