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...

Platelet derived growth factor (PDGF) plays role in heart regeneration In research that one day may lead to the discovery of how to regenerate tissue damaged by heart disease, investigators at Childrens Hospital Los Angeles have identified PDGF as a key factor in the proliferation and transformation of epicardial cells, one type of cell that surrounds heart muscle and contributes to vessels. The study was published online September 21 in advance of the publication of the Proceedings of the...

Malfunction of a protein has been linked to a form of mental retardation that affects up to one out of every 500 males, says Nasser K. Yaghi, a Texas A&M University magna cum laude biology graduate who was selected to participate in a medical research project at Harvard that has been published in the journal Nature. The results of the study suggest that if the condition is detected early in fetal development a treatment could possibly be developed to correct the problem. "X-linked...

Now possible to film development of fruit fly and of zebrafish's eyes and brain The scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, who 'fathered' the Digital Embryo have now given it wings, creating the Fly Digital Embryo. In work published today in Nature Methods, they were able to capture fruit fly development on film, and were the first to clearly record how a zebrafish's eyes and midbrain are formed. The improved technique will also help to shed...

A new study is shedding light on a key genetic step in the evolution of animal limbs from the fins of fish. A team of researchers identified two genes crucial to fin development. The researchers wrote in the journal Nature that the loss of these genes could have been an "important step" in the evolutionary transformation of fins into limbs. Marie-Andree Akimenko from the University of Ottawa in Canada led the research. She and her colleagues began their study by looking at the development...

This image may bring to mind a patchwork quilt, or a picture taken from a gallery of abstract paintings, but the artisan behind it is actually Mother Nature, with a little help from scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. Using an electron microscope, Virginie Lecaudey in Darren Gilmour's group at EMBL captured this snapshot of the beginnings of an organ which plays a central role in how zebrafish perceive the world around them "“ the...

Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC), Berkeley, have successfully attached imaging probes to glycans "“ the sugar molecules that are abundant on the surfaces of living cells "“ in the embryos of zebrafish less than seven hours after fertilization. Glycans are key regulators of the processes that guide cell development, and zebrafish are a top vertebrate model organism of...

A research team led by scientists from the Duke University Medical Center has developed a way to simultaneously look at the effects of 125 mutations occurring on 14 different genes. They used zebrafish as a model to analyze the function of every known mutation in an inherited syndrome called BBS, Bardet-Biedl Syndrome. Being able to analyze the functions and interactions of all mutations in a complex inherited disease could have implications for a broad range of disorders. The study found...

Animal model uses mysterious enzyme also found in people's brains Michael E. Baker, PhD, a researcher at the University of California, San Diego School of Medicine has discovered that zebrafish "“ an important animal model in disease and environmental studies "“ could provide the means to help scientists eventually reveal the function of a mysterious enzyme linked to the steroid cortisol, and found in the human brain. In people and other vertebrates, steroids like cortisol perform...

Cellular grown-ups outperform stem cells in cardiac repair Bony fish like the tiny zebrafish have a remarkable ability that mammals can only dream of: if you lop off a chunk of their heart they swim sluggishly for a few days but within a month appear perfectly normal. How they accomplish this "” or, more importantly, why we can't "” is one of the significant questions in regenerative medicine today. In a paper published in the March 25, 2010 issue of Nature, researchers working at...

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...
