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...

Squid And Zebrafish Spark Camouflage Inspiration

University of Bristol researchers have created artificial muscles that can be transformed to mimic the camouflaging abilities of squid and zebrafish. The team demonstrated two individual transforming mechanisms that they believe could be used in "smart clothing" to trigger camouflaging tricks similar to animals observed in the wild. "We have taken inspiration from nature's designs and exploited the same methods to turn our artificial muscles into striking visual effects,"  Jonathan...

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...

Researchers from the University of Bristol have created artificial muscles that can be transformed at the flick of a switch to mimic the remarkable camouflaging abilities of organisms such as squid and zebrafish. They demonstrate two individual transforming mechanisms that they believe could be used in 'smart clothing' to trigger camouflaging tricks similar to those seen in nature. The study is published today, 2 May, in IOP Publishing's journal Bioinspiration and Biomimetics, and is...

Just a handful of cells in the embryo are all that's needed to form the outer layer of pumping heart muscle in an adult zebrafish. Researchers at Duke University Medical Center used zebrafish embryos and careful employment of a new technique that allows for up to 90 color labels on different cells to track individual cells and cell lines as the heart formed. The scientists were surprised by how few cells went into making a critical organ structure and they suspect that other organs may...

Understanding the damage that pollution causes to both wildlife and human health is set to become much easier thanks to a new green-glowing zebrafish. Created by a team from the University of Exeter, the fish makes it easier than ever before to see where in the body environmental chemicals act and how they affect health. The fluorescent fish has shown that oestrogenic chemicals, which are already linked to reproductive problems, impact on more parts of the body than previously thought....

A novel anti-leukemia compound with little toxicity successfully treated zebrafish with T-cell acute lymphoblastic leukemia (T-ALL), suggesting its potential to become a new highly targeted therapy for humans — even those resistant to conventional therapies — according to results from a study published online today in Blood, the Journal of the American Society of Hematology (ASH). T-ALL is a cancer of the white blood cells in which genetic mutations cause normal immature...

With a pinpoint UV laser beam, researchers are able to learn more about protein synthesis University of Oregon scientists collaborating with an Oregon company that synthesizes antisense Morpholinos for genetic research have developed a UV light-activated on-off switch for the vital gene-blocking molecule. Based on initial testing in zebra-fish embryos, the enhanced molecule promises to deliver new insights for developmental biologists and brain researchers. The seven-member team...

In testing the effects of the controversial chemical bisphenol A (BPA) on zebrafish, UWM scientist Daniel Weber found himself in familiar territory. The results he observed were similar to those he´d seen when exposing the fish to mercury during their early development — profound behavioral changes occurred not only immediately after hatching, but also in adulthood. Like developmental exposure to mercury, adult fish that had been exposed to tiny amounts of BPA as embryos had...

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...
