redOrbit Staff & Wire Reports - Your Universe Online A team of scientists from Uruguay have genetically modified a flock of nine young sheep, causing the lambs to glow in the dark whenever they are exposed to ultraviolet light. According to Slashgear’s Brian Sin, the scientists altered the creatures using the fluorescent protein from an Aequorea jellyfish. The sheep, which were born last October at the Animal Reproduction Institute of Uruguay, give off a glowing green color when...
April Flowers for redOrbit.com - Your Universe Online Two new studies from the Wellcome Trust Sanger Institute involving the genome of zebrafish have been published in the journal Nature this week, giving insight into the relationship between humans, zebrafish and genetic mutations. FAMILY TIES According to the first study, 70 percent of protein-coding human genes are related to zebrafish genes, and 84 percent of the genes known to be associated with human disease have a counterpart...
Cell Press [ Video 1 ] [ Video 2 ] For the first time, researchers have been able to see a thought "swim" through the brain of a living fish. The new technology is a useful tool for studies of perception. It might even find use in psychiatric drug discovery, according to authors of the study, appearing online on January 31 in Current Biology, a Cell Press publication. "Our work is the first to show brain activities in real time in an intact animal during that animal's natural...
Brett Smith for redOrbit.com – Your Universe Online Scientific journal publisher Mary Ann Liebert, Inc., leveraging the popularity of zebrafish among school children, announced a special edition of their peer-reviewed journal Zebrafish highlighting several scientific studies submitted by young researchers. "The emphasis is on teaching students how to think, rather than on what to think," said Stephen Ekker, PhD, Editor-in-Chief of Zebrafish and Professor of Medicine at the Mayo...
Cell Press Vertebrates' transition to living on land, instead of only in water, represented a major event in the history of life. Now, researchers reporting in the December issue of the Cell Press journal Developmental Cell provide new evidence that the development of hands and feet occurred through the gain of new DNA elements that activate particular genes. "First, and foremost, this finding helps us to understand the power that the modification of gene expression has on shaping our...
Technische Universitaet Muenchen New model for in vivo studies of mitochondria transport in nerve cells Scientists have demonstrated a new way to investigate mechanisms at work in Alzheimer's and other neurodegenerative diseases, which also could prove useful in the search for effective drugs. For new insights, they turned to the zebrafish, which is transparent in the early stages of its life. The researchers developed a transgenic variety, the "MitoFish," that enables them to see –...
University of Veterinary Medicine, Vienna Billy Ocean may not have been thinking of fish when he wrote “The Color of Love”, but Sophie Hutter, Attila Hettyey, Dustin Penn, and Sarah Zala from the Konrad Lorenz Institute of Ethology of the University of Veterinary Medicine, Vienna were able to show that zebrafish males and females both wear their brightest colors while wooing a mate. Elaborate secondary sexual displays are often overlooked because many species attract mates through...
redOrbit Staff & Wire Reports - Your Universe Online New research sheds light on the nascent field of ethorobotics, the study of bioinspired robots that interact with animal counterparts. Scientists from Polytechnic Institute of New York University (NYU-Poly) studied the role of real-time feedback in attracting or repelling live zebrafish in the presence of a robotic fish. The findings revealed that zebrafish show increased attraction to robots that are able to modulate their...
Mayo Clinic researchers and an international team of scientists have developed a highly-efficient means of editing zebrafish genomes for research purposes, eliminating a bottleneck that has stymied biomedical scientists from using the fish as a model for human disease. The details appear online today in the journal Nature. For many researchers, zebrafish are becoming the model of choice for genetic studies. However, the inability to efficiently target genetic modifications has delayed...
Connie K. Ho for redOrbit.com Apes and humans are thought to be intertwined in evolutionary theory, but how about fish and humans? A new study utilized zebrafish in a study regarding human brain disorders. In particular, Massachusetts Institute of Technology (MIT) researchers recently revealed that they took a fresh approach to understanding the roles of genes linked to autism and demonstrated how zebrafish could be utilized in examining the genes that contribute to human brain disorders....

The Blue Danio (Danio kerri), also known as Kerr's Danio, is a tropical fish that originates from South-east Asia on the islands of Langkawi and Ko Yao Yai in the Malaysian Peninsula. It is sometimes found in freshwater aquariums of hobbyists. The taxonomic name honors A.F.G. Kerr, who collected the first specimen on Ko Yao Yai in 1929. The Blue Danio is blue colored with several pink/gold lines from the tail to the gills which may or may not be continuous, over a powdery blue side. It...
The Celestial Pearl Danio, Celestichthys margaritatus, often referred to in the aquarium trade as Galaxy rasbora or Microrasbora. It has so far been found only in a very small area east of Inle Lake at an altitude of over 3280.84 ft (1000 m). The fish lives in relatively cool, alkaline water. Discovered in 2006 the species quickly appeared in the aquarium trade where its small size and bright colors made it an instant hit. It is the only species in the genus Celestichthys. Conservation...
The Giant Danio (Devario aequipinnatus) is a tropical fish belonging to the minnow family (Cyprinidae). Originating in Sri Lanka, Nepal, and the West coast of India, it grows to a maximum length of 6 in (15 cm), making it one of the largest of the Danionins. They are characterized by a blue and yellow torpedo shaped body with gray and clear fins. In the wild, Giant Danios live in clear streams and rivers among hills at elevations up to 1000 ft (300 m) above sea level. Their native...
The Zebrafish (Danio rerio) is a tropical fish belonging to the minnow family (Cyprinidae). It is a popular aquarium fish, where it is frequently sold under the trade name Zebra danio, and is also an important model organism. Characteristics The zebrafish arose in the Ganges region in Eastern India and is also native to Pakistan, Bangladesh, Nepal and Myanmar. It commonly inhabits streams, canals, ditches, ponds and slow-moving to stagnant water bodies, including rice fields. The...
The Glowlight danio is a small fish with a maximum length of 1.25 in (4 cm). Its coloration is brown, yellow, green and red. The Glowlight can live in waters that are (20-25 degrees Celsius), 6 to 7 pH, with a soft to medium hardness and a low to medium salinity. These fish are compatible with other danios and typically live from 1 to 3 years. They are moderately difficult fish to keep, and breeding can be even harder. Danio choprai or the Glowlight danio is a small, schooling fish...
