Researchers identify genes that help trout find their way home. Duke Today, April 26, 2017. In the spring when water temperatures start to rise, rainbow trout that have spent several years at sea traveling hundreds of miles from home manage, without maps or GPS, to find their way back to the rivers and streams where they were born for spawning. Researchers have identified genes that enable the fish to perform this extraordinary homing feat with help from Earth’s magnetic field.

In the ocean, clever camouflage beats super sight

In the ocean, clever camouflage beats super sight. Duke Today, Aug. 23, 2016. Some fish blend seamlessly into their watery surroundings with help from their silvery reflective skin. Researchers have long assumed that squid, shrimp and other ocean animals could see through this disguise, thanks to an ability to detect a property of light — called polarization — that humans can’t see. But a new study finds that not even polarization vision helps animals spot silvery fish from afar. Picked up by Cosmos.
