(Phys.org)—In a normal rainbow, red is always on "top" while violet is on the "bottom." This is true whether the rainbow is created by a glass prism or by water droplets in the sky, and is due to the way that these materials ...

Rainbow trout genome sequenced

Using fish bred at Washington State University, an international team of researchers has mapped the genetic profile of the rainbow trout, a versatile salmonid whose relatively recent genetic history opens a window into how ...

Virus plus microplastics equal double whammy for fish health

Microplastics—tiny particles generated as plastics weather and fragment—pose a growing threat to ecosystem and human health. A new laboratory study shows these threats extend beyond direct physical or chemical impacts, ...

Climate change to produce more rainbows, study finds

Climate change will increase opportunities to see rainbows, according to a new study led by researchers at the University of Hawai'i (UH) at Mānoa. The study's authors estimate that by 2100, the average land location on ...

Non-native fish are main consumers of salmon in reservoirs

When warmwater fish species like bass, walleye and crappie that are not native to the Pacific Northwest, but prized by some anglers, overlap with baby spring chinook salmon in reservoirs in Oregon's Willamette River they ...
