Fish DNA For Fingers
2014-01-22 12:35:31

Brett Smith for redOrbit.com - Your Universe Online A new study from a team of Swiss researchers published in the journal PLOS Biology has found that our fish ancestors had the genetic machinery for fingers, but these structures did not develop until the evolution of limbs in amphibians. “The basics of the regulatory mechanism are there in the fish,” said study author Denis Duboule, a geneticist at the University of Geneva and Federal Institute of Technology in Lausanne....

AGAWAM, Mass., Dec. 3, 2013 /PRNewswire/ -- Microtest Laboratories, a leader in testing services and contract manufacturing for the medical device, pharmaceutical, and biotechnology industries, is adding OECD Fish Embryo Toxicity Testing to its portfolio of services. Pharmaceutical, chemical, and related manufacturing plants are under increased scrutiny for the potential impact of their products or waste water on the environment. Pesticides are a major example. But recently, the...

A new mechanism that regulates the way blood vessels grow and connect to each other has been discovered by an international team of researchers at Karolinska Institutet in Sweden, and Heinrich Heine University Düsseldorf, Germany. The knowledge might open up new opportunities for future cancer therapy. The study is published in the scientific journal PNAS. If stretched out, the blood vessels in a human body would reach more than twice around the earth. The complex circulatory system...

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...

Anxious Zebrafish Help NYU-Poly Researchers Understand How Alcohol Affects Fear BROOKLYN, N.Y., July 31, 2013 /PRNewswire/ -- The latest in a series of experiments testing the ability of robots to influence live animals shows that bio-inspired robots can not only elicit fear in zebrafish, but that this reaction can be modulated by alcohol. These findings may pave the way for new methodologies for understanding anxiety and other emotions, as well as substances that alter them....

Genetically Modified Glow In The Dark
2013-04-29 04:53:42

redOrbit Staff & Wire Reports - Your Universe Online A team of scientists from Uruguay have genetically modified a flock of nine young sheep, causing the lambs to glow in the dark whenever they are exposed to ultraviolet light. According to Slashgear´s Brian Sin, the scientists altered the creatures using the fluorescent protein from an Aequorea jellyfish. The sheep, which were born last October at the Animal Reproduction Institute of Uruguay, give off a glowing green color...

Zebrafish Genome Could Have Significant Implications For Human Health
2013-04-18 09:59:16

April Flowers for redOrbit.com - Your Universe Online Two new studies from the Wellcome Trust Sanger Institute involving the genome of zebrafish have been published in the journal Nature this week, giving insight into the relationship between humans, zebrafish and genetic mutations. FAMILY TIES According to the first study, 70 percent of protein-coding human genes are related to zebrafish genes, and 84 percent of the genes known to be associated with human disease have a counterpart...

What A Thought 'Swimming' Through The Brain Of A Fish Looks Like
2013-01-31 14:01:42

Cell Press [ Video 1 ] [ Video 2 ] For the first time, researchers have been able to see a thought "swim" through the brain of a living fish. The new technology is a useful tool for studies of perception. It might even find use in psychiatric drug discovery, according to authors of the study, appearing online on January 31 in Current Biology, a Cell Press publication. "Our work is the first to show brain activities in real time in an intact animal during that animal's natural...

The Blue Danio (Danio kerri), also known as Kerr's Danio, is a tropical fish that originates from South-east Asia on the islands of Langkawi and Ko Yao Yai in the Malaysian Peninsula. It is sometimes found in freshwater aquariums of hobbyists. The taxonomic name honors A.F.G. Kerr, who collected the first specimen on Ko Yao Yai in 1929. The Blue Danio is blue colored with several pink/gold lines from the tail to the gills which may or may not be continuous, over a powdery blue side. It...

The Celestial Pearl Danio, Celestichthys margaritatus, often referred to in the aquarium trade as Galaxy rasbora or Microrasbora. It has so far been found only in a very small area east of Inle Lake at an altitude of over 3280.84 ft (1000 m). The fish lives in relatively cool, alkaline water. Discovered in 2006 the species quickly appeared in the aquarium trade where its small size and bright colors made it an instant hit. It is the only species in the genus Celestichthys. Conservation...
