Researchers Tease Out Cues That Impact Schooling Fish Behavior
2013-10-31 11:12:23

NYU-Poly Recent studies from two research teams at the Polytechnic Institute of New York University (NYU-Poly) demonstrate how underwater robots can be used to understand and influence the complex swimming behaviors of schooling fish. The teams, led by Maurizio Porfiri, associate professor of mechanical and aerospace engineering at NYU-Poly, published two separate papers in the journal PLOS ONE. These studies are the latest in a significant body of research by Porfiri and collaborators...

Scientists also found that gene disrupts heart valve development & growth Research on the DNA of a large multi-generational family has provided a genetic clue that enabled scientists to pinpoint a gene that plays a role in mitral valve prolapse (MVP), a common cardiac disease that is a leading cause of heart failure, according to a study presented today (Thursday, Oct. 24) at the American Society of Human Genetics 2013 meeting in Boston. The scientists who located the gene, named...

Reproductive Trait In Fish Impedes Tissue Regeneration
2013-10-14 11:46:23

Cell Press New research on the reproductive habits of zebrafish offers an explanation as to why some animals' bodies repair tissues. The research team previously noticed that male zebrafish regenerate their pectoral fins poorly, as compared to females. Their latest findings, publishing in the October 14 issue of the Cell Press journal Developmental Cell, reveal the basis for this sex-specific regenerative deficiency: structures that are used to improve reproductive success. The scenario...

Studies in fish and cultured human cells provide insight into a human disease Children born with developmental disorders called cohesinopathies can suffer severe consequences, including intellectual disabilities, limb shortening, craniofacial anomalies, and slowed growth. Researchers know which mutations underlie some cohesinopathies, but have developed little understanding of the downstream signals that are disrupted in these conditions. In a study published in the October 3, 2013,...

Scientists reveal how organic mercury can interfere with vision More than one billion people worldwide rely on fish as an important source of animal protein, states the United Nations Food and Agriculture Organization. And while fish provide slightly over 7 per cent of animal protein in North America, in Asia they represent about 23 per cent of consumption. Humans consume low levels of methylmercury by eating fish and seafood. Methylmercury compounds specifically target the central...

Researchers Use Zebrafish To Reel In New Epilepsy Treatment
2013-09-03 15:36:39

Brett Smith for redOrbit.com - Your Universe Online The phrase ‘thinking outside the box’ has become so common these days, it’s almost thought of as an oxymoronic cliché. However, a group of University of California, San Francisco researchers, doing just that, may have stumbled onto a new drug to treat a certain form of childhood epilepsy. Although previous studies have found antihistamines can make seizures worse, the UCSF researchers found that the antihistamine clemizole can...

Function Of Protein As Transporter Of Toxic Chemicals Discovered In The Zebrafish Embryo
2013-09-03 10:49:57

Helmholtz Centre for Environmental Research Researchers at the Helmholtz Centre for Environmental Research (UFZ), together with colleagues from the Swiss Eawag aquatic research institute, have discovered a protein which transports chemicals out of the embryo of the zebrafish and in this way protects the embryo against toxic substances. However, certain environmental chemicals render this protective mechanism ineffective, so that the fish embryos become more sensitive to toxic substances....

Fear Factor For Fish: A Mix Of Robots And Alcohol
2013-08-01 08:43:15

April Flowers for redOrbit.com - Your Universe Online An international team of scientists has shown bio-inspired robots can not only elicit fear in zebrafish, but that this reaction can be modulated by alcohol. These findings, published in PLoS ONE, are the latest in a series of experiments designed to test the ability of robots to influence live animals. The team hopes to pave the way for new methodologies for understanding anxiety and other emotions, as well as substances that alter...

Scientists from the University of Sheffield have paved the way for new treatments for a common genetic disorder thanks to pioneering research on zebrafish — an animal capable of mending its own heart. Charcot Marie Tooth disease (CMT) is the most common genetic disorder affecting the nervous system. More than 20,000 people in the UK suffer from CMT, which typically causes progressive weakness and long-term pain in the feet, leading to walking difficulties. There is currently no cure...

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...
