Revolutionary nanotechnology illuminates brain cells at work

...differently colored tags made from variants of the jellyfish Green Fluorescent Protein (GFP). The colored tags are placed at each end of the molecule making a "biosensor." When the substance of interest binds to the sensor, the sensor backbone becomes reoriented, and the reorientation can be detected. Since li...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...cimens and images include suspected new species of jellyfish and benthic bristle worms, and the first squid and octopus ever found in the area. Scientists were also intrigued to discover among other things two species of sand flea-like crustaceans (amphipods) which, though familiar, had never before been foun...

Fluorescing lab worms signal longer life spans

...t day of adult life," Johnson said. Obtained from jellyfish and widely used in genetic experiments, the green fluorescent protein was attached to a heat-shock protein in the worms called HSP-16. "HSP-16 alone is probably not responsible for observed differences in survival, but instead is likely reflective of...

Tiny polyps gorge themselves to survive coral bleaching

...for mutual benefit. The coral polyp, a relative of jellyfish and anemones, provides a safe home within its cells for the algae while the algae convert sunlight into energy for the polyp. Grottoli said that when the temperature of the waters around a reef exceeds that upper limit and stays there for more than...

Sea coral's trick helps scientists tag proteins

...ent protein (GFP) from a species of bioluminescent jellyfish in 1992, and Martin Chalfie, who first used GFP for labeling in 1994, said Marc Zimmer, a computational chemist at Connecticut College and author of Glowing Genes: A Revolution in Biotechnology (2005). Since then, HHMI investigator Roger Tsien has de...

Scientist warns of threat to last stronghold of endangered turtle

... Europe and even the Indian Ocean to feed on their jellyfish prey. Once we have detailed information our tracking work will feed directly into strategies for marine protected areas in Gabon and farther afield and more sustainable fisheries. We are just beginning to understand the importance of the leatherba...

Lighting up life: Cold Spring Harbor Protocols presents tips for creating glowing plants

...ade ago, biologists isolated a unique protein from jellyfish that could be inserted into other organisms—from E. coli to pigs—and cause them to radiate a brilliant green color. This green fluorescent protein (GFP) has allowed biologists to make many new discoveries regarding how living cells function. But on...
