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....

A bioinspired robot has provided the first experimental evidence that live zebrafish can be influenced by engineered robots. Results published today, 8 June, in IOP Publishing's journal Bioinspiration and Biomimetics, provide a stepping stone on the path to using autonomous robots in an open environment to monitor and control fish behavior. In the future, water-based robots could potentially contribute to the protection of endangered animals and the control of pest species. The...

Microscopes provide valuable insights in the structure and dynamics of cells, in particular when the latter remain in their natural environment. However, this is very difficult especially for higher organisms. Researchers of Karlsruhe Institute of Technology (KIT), the Max Planck Institute for Polymer Research, Mainz, and the American National Institutes of Health (NIH) have now developed a new method to visualize cell structures of an eighth of a micrometer in size in living fish larvae. It...

Researchers have developed a new technique which allows them to measure brain activity in large populations of nerve cells at the resolution of individual cells. The technique, reported today in the journal Nature, has been developed in zebrafish to represent a simplified model of how brain regions work together to flexibly control behavior. Our thoughts and actions are the product of large populations of nerve cells, called neurons, working in harmony, often millions at a time. Measuring...

Changing the conditions that zebrafish are kept in could have an impact on their behavior in animal studies and the reliability of results, according to scientists from Queen Mary, University of London. Zebrafish, like rats and mice, are often used by neuroscientists to explore mechanisms controlling behavior and in the search for new compounds to treat behavioral disease such as addiction, attention deficit disorders or autism. It is known that housing and handling affects the results...

FINDINGS: Whitehead Institute scientists have identified conserved, long intervening non-coding RNAs (lincRNAs) that play key roles during brain development in zebrafish, and went on to show that the human versions of these RNAs can substitute for the zebrafish lincRNAs. RELEVANCE: Despite their prevalence in the cell, lincRNAs have been referred to as the "dark matter" of all the transcribed RNAs because little is known of their functions or mechanisms. Until now, lincRNAs have been...

AGAWAM, Mass. July 6, 2011 /PRNewswire/ -- Microtest Laboratories has announced a new fast-track test to screen plastics and polymers in medical devices for toxicity using Zebrafish embryos (Danio rerio), a technique already widely utilized in drug development studies. "Testing has revealed that Zebrafish embryos are highly susceptible to toxins. In fact, Zebrafish labs are ubiquitous in most universities and research hospitals," said Steven Richter, Ph.D., president and scientific...

Mayo Clinic researchers have designed a new tool for identifying protein function from genetic code. A team led by Stephen Ekker, Ph.D., succeeded in switching individual genes off and on in zebrafish, then observing embryonic and juvenile development. The study appears in the journal Nature Methods. The work could help shed light on health-related problems such as how cancerous cells spread, what makes some people more prone to heart attacks, (http://www.mayoclinic.org/heart-attack/) or how...

Discovery suggests new drug targets and markers to help treat the aggressive, deadly skin cancer Thanks to the zebrafish, there is new hope for people with melanoma, an aggressive skin cancer that is responsible for approximately 8,700 deaths each year in the United States. In a study that was published in the March 24th issue of the journal Nature, and featured on the cover, researchers identified SETDB1 as a new gene that promotes the growth of melanoma and may play a role in up to 70...
