Research from the University of Exeter has revealed that the rock goby (Gobius paganellus), an unassuming little fish commonly found in rock pools around Britain, southern Europe, and North Africa, is a master of camouflage and can rapidly change colour to conceal itself against its background.

Whether hiding from predators or from families hunting in rock pools, the rock goby can change both its colour and brightness to match its background in just one minute. (more…)

Amoeba May Offer Key Clue to Photosynthetic Evolution

Stanford, CA— The major difference between plant and animal cells is the photosynthetic process, which converts light energy into chemical energy. When light isn’t available, energy is generated by breaking down carbohydrates and sugars, just as it is in animal and some bacterial cells. Two cellular organelles are responsible for these two processes: the chloroplasts for photosynthesis and the mitochondria for sugar breakdown. New research from Carnegie’s Eva Nowack and Arthur Grossman has opened a window into the early stages of chloroplast evolution. Their work is published online by the Proceedings of the National Academy of Sciences in the week of February 27-March 2. (more…)

GAINESVILLE, Fla. — University of Florida researchers received a rare 25-foot-long, deep-water giant squid Monday, the only one of its kind in the collections of the Florida Museum of Natural History.

Recovered by recreational fishermen who found the creature floating on the surface about 12 miles offshore from Jensen Beach Sunday, museum scientists collected the specimen from the Florida Fish and Wildlife Conservation Commission Tequesta Field Laboratory in Palm Beach County and returned to the Gainesville campus late Monday.
