So-called model organisms have long been at the core of biomedical research, allowing scientists to study the ins and outs of human disorders in non-human subjects. In the ideal, such models accurately recapitulate a human disorder so that, for example, the Parkinson's disease observed in a rat model would be virtually indistinguishable from that in a human patient. The reality, of course, is that rats aren't human, and few models actually faithfully reflect the phenotype of the disease in...

US scientists have found that newborn mice can repair themselves after an injury, an important discovery that brings hopes that healing can occur with damaged hearts in people. Scientists removed large chunks of heart out of mice that were only a day old, only to find that their hearts were restored within three weeks. Fish and amphibians are known to have the power to re-grow parts of their hearts after major injuries, but the study, published in the journal Science, is the first time the...

(Ivanhoe Newswire) "“ Blue-green algae may be responsible for producing an estrogen-like compound in the environment which could disrupt the normal activity of reproductive hormones and adversely affect fish, plants, and human health. Previously, human activities were thought to be responsible for producing these impacts. Researchers looked into blue-green algae and their effects on zebrafish. They discovered the algae may add a new harmful element into the way they understand and...

Researchers have identified a cell in zebrafish that can be transplanted from one fish to another to regenerate nephrons, providing the potential to improve kidney function It is estimated that up to 10 percent of the U.S. population may have some form of renal disease, with 450,000 patients with end stage renal disease (ESRD) requiring hemodialysis. Researchers at Brigham and Women's Hospital, Massachusetts General Hospital and the University of Pittsburgh have identified a cell in zebrafish...

Breakthrough sheds light on poorly understood region of the brain 1. Scientists from the Agency of Science, Technology and Research/Duke-NUS Neuroscience Research Partnership (A*STAR/Duke-NUS NRP), A*STAR's Institute of Molecular and Cell Biology, and the National University of Singapore have made a breakthrough concerning how anxiety is regulated in the vertebrate brain. Their work, published in the journal Current Biology, sheds light on how the brain normally shuts off anxiety and also...

The imaging of tumour growth in zebrafish has revealed for the first time how newly formed cancer cells have the capacity to co-opt the immune system into spreading the disease, leading the way for investigations into potential therapies for eliminating early-stage cancer in humans. Using different coloured fluorescent tags, scientists at the University of Bristol labelled immune cells and tumour-forming cells in the translucent zebrafish in order to track their behaviour and interactions by...

By Kitta MacPherson, Princeton University A gene that can cause congenital heart defects has been identified by a team of scientists, including a group from Princeton University. The discovery could lead to new treatments for those affected by the conditions brought on by the birth defect. Princeton researchers focused on identifying and studying the gene in zebrafish embryos, and the team's work expanded to include collaborations with other groups studying the genetics of mice and people....

A tiny, translucent juvenile zebrafish, on the hunt for even littler prey, has offered up a big insight into how a specific circuit of nerve cells functions in the brain. The technique used to illuminate this circuitry, and the fish model itself, provide one of the first insights into the way individual sets of neurons control a specific behavior. The finding, reported in Science, (October 29, 2010), also illuminates the mastery of evolution, in the finely tuned mechanism the research...

Inhibiting certain brain cells sharpens animal's response to small and quick visual stimuli Between alerting us to danger and allowing us to spot prey, vision keeps many animals, including humans, alive. But exactly how does this important sense work, and why is it easier for us to spot movement of small objects in our field of vision, than to notice other things? The complexity of the neural network that supports vision has long baffled scientists. Now, with a new technology and support from...

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...
