New Window On Brain Diseases Opened With See-through 'MitoFish'
2012-12-06 09:42:01

Technische Universitaet Muenchen New model for in vivo studies of mitochondria transport in nerve cells Scientists have demonstrated a new way to investigate mechanisms at work in Alzheimer's and other neurodegenerative diseases, which also could prove useful in the search for effective drugs. For new insights, they turned to the zebrafish, which is transparent in the early stages of its life. The researchers developed a transgenic variety, the "MitoFish," that enables them to see...

UCSF scientists use tiny zebrafish to screen for drugs to help control obesity, diabetes, other conditions A tiny, translucent zebrafish that glows green when its liver makes glucose has helped an international team of researchers identify a compound that regulates whole-body metabolism and appears to protect obese mice from signs of metabolic disorders. Led by scientists at the University of California, San Francisco (UCSF), the work demonstrates how a fish smaller than a grain of rice...

Zebrafish Perform Colorful Courtship Displays
2012-11-30 14:58:35

University of Veterinary Medicine, Vienna Billy Ocean may not have been thinking of fish when he wrote “The Color of Love”, but Sophie Hutter, Attila Hettyey, Dustin Penn, and Sarah Zala from the Konrad Lorenz Institute of Ethology of the University of Veterinary Medicine, Vienna were able to show that zebrafish males and females both wear their brightest colors while wooing a mate. Elaborate secondary sexual displays are often overlooked because many species attract mates...

Interaction Of Robots And Animals Studied Through Ethorobotics
2012-11-21 05:20:58

redOrbit Staff & Wire Reports - Your Universe Online New research sheds light on the nascent field of ethorobotics, the study of bioinspired robots that interact with animal counterparts. Scientists from Polytechnic Institute of New York University (NYU-Poly) studied the role of real-time feedback in attracting or repelling live zebrafish in the presence of a robotic fish. The findings revealed that zebrafish show increased attraction to robots that are able to modulate their...

Unique Spinal Nerve Cell Activity Discovery Announced

University of Leicester Research team identifies novel forms of activity linked to development of motor behaviors such as swimming Scientists from the University of Leicester have hit upon unique forms of spinal nerve activity that shape output of nerve cell networks controlling motor behaviors. The breakthrough in the Department of Biology at the University of Leicester is announced today (5pm GMT on Thursday Nov 8) in the journal Current Biology. The three- year study was funded by...

Boosting the activity of a vitamin-sensitive cell adhesion pathway has the potential to counteract the muscle degeneration and reduced mobility caused by muscular dystrophies, according to a research team led by scientists at the University of Maine. The discovery, published 23 October in the open access journal PLOS Biology, is particularly important for congenital muscular dystrophies, which are progressive, debilitating and often lethal diseases that currently remain without cure. The...

While it is well known that starfish, zebrafish and salamanders can re-grow damaged limbs, scientists understand very little about the regenerative capabilities of mammals. Now, researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine report on the regenerative process that enables rats to re-grow their bladders within eight weeks. In PLOS ONE, a peer-reviewed, online publication, the scientists characterize this unique model of bladder regeneration with the...

Fat Hormone May Play Role In Hearing, Vision Loss
2012-09-27 15:18:31

Lee Rannals for redOrbit.com — Your Universe Online A new study indicates that leptin, or the "fat hormone," may play a role in hearing and vision loss, on top of weight gain. Researchers wrote in the journal General and Comparative Endocrinology that leptin could ultimately help doctors better understand sensory loss in humans. During the study, the scientists were able to develop zebrafish that were able to produce low leptin. While studying the zebrafish, scientists...

Mayo Clinic researchers and an international team of scientists have developed a highly-efficient means of editing zebrafish genomes for research purposes, eliminating a bottleneck that has stymied biomedical scientists from using the fish as a model for human disease. The details appear online today in the journal Nature. For many researchers, zebrafish are becoming the model of choice for genetic studies. However, the inability to efficiently target genetic modifications has delayed...

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...
