Eating fatty fish and marine omega-3 fatty acids may reduce risk of heart failure
Eating fatty fish and marine omega-3 fatty acids, which are found in fish oil, seems to protect men from heart failure according to one of the largest studies to investigate the association. view more (2009-04-22)
Limited climate tracking in European trees despite 10,000 years of postglacial warmth
The relative roles of environment and history as controls of large-scale species distributions is a crucial issue in biogeography and macroecology. In the forthcoming issue of Ecology Letters Svenning & Skov use bioclimatic modelling to show that among 55 native European tree species, 36 occupy less than 50% of their climatically suitable... view more...

Can fish factories make cheap drugs?
Written by Amitabh Avasthi A HUMAN blood-clotting factor used to treat some people with haemophilia and accident victims suffering serious bleeding has been produced using genetically modified fish. view more (2004-09-08)
Competition between species curbs selfishness?
Animals are in constant competition over procreative resources. The interests of the individual and the population are not necessarily one and the same; aggressive insects may fare well in the mating competition, but eventually the proliferation of aggressive genes will weaken the procreative efficiency of the species. view more (2004-12-20)
More fish oil, less vegetable oil, better for your health
Scientists have provided new evidence that using more fish oil than vegetable oil in the diet decreases the formation of chemicals called prostanoids, which, when produced in excess, increase inflammation in various tissues and organs. view more (2007-07-27)
International team shows mercury concentrations in fish respond quickly to increased deposition
A joint Canadian-American research team have, for the first time, demonstrated that mercury concentrations in fish respond directly to changes in atmospheric deposition of the chemical. view more (2007-09-18)
Consumption of certain fish during pregnancy associated with poorer cognitive performance
Children who eat fish more than 3 times per week show a worse performance in the general cognitive, executive and perceptual-manipulative areas. view more (2009-11-13)
Global map shows new patterns of extinction risk
The most detailed world map of mammals, birds and amphibians ever produced shows that endangered species from these groups do not inhabit the same geographical areas, says new research published today. view more (2006-11-02)
Scientists Discover How Fish Evolved To Float At Different Sea Depths
Scientists at the University of Liverpool have discovered how fish have evolved over the last 400 million years to stay motionless at different water depths. view more (2005-03-18)
New Approach Needed if Fish Stocks are to Survive
A new approach to fisheries management, taking into account the full range of human impacts on the ecosystem, is needed if fish stocks are to survive, according to Professor Chris Frid of the University of Newcastle upon Tyne, speaking at the EurOCEAN European Conference on Marine Science and Ocean Technology in Galway today. "Fishing is... view more... (2004-05-11)
Fish slime crock of gold at end of rainbow
The slippery mucus on the skin of rainbow trout is being studied by scientists as a possible source of new medicines to fight infectious diseases, according to research presented today (Monday, 06 September 2004) at the Society for General Microbiology's 155th Meeting at Trinity College Dublin. view more (2004-08-23)
Spookfish uses mirrors for eyes
A remarkable new discovery shows the four-eyed spookfish to be the first vertebrate ever found to use mirrors, rather than lenses, to focus light in its eyes. view more (2009-01-08)
Nitrogen retained through loss
The nitrogen cycle plays a major role in seagrass fields. Dutch researcher Arie Vonk studied the nitrogen dynamics of seagrasses in Indonesia. He discovered that the interaction between seagrasses, animals and microorganisms results in an efficient nitrogen cycle in tropical seagrass fields. Consequently the nitrogen lost from seagrasses is still... view more... (2008-05-23)
Fish oil -- helpful or harmful?
Fish oil supplements may help some cardiac patients while harming others, suggests a new review of evidence compiled by St. Michael's Hospital and University of Toronto researchers. view more (2008-01-15)
Stress delays puberty
NWO research at Utrecht University has shown that when carp are subjected to stress, the development of their genital organs is delayed, so that they reach puberty later. It is likely that the stress hormone cortisol plays a major role in delaying puberty. Changes in water temperature produce stress in fish. Dimitri Consten of Utrecht University... view more...

Live via Satellite: Scientists to Track Caspian Sea Sturgeons
Scientists working in the Ural River, Kazakhstan, have successfully attached Pop-up Archival Transmitting (PAT) tags to four sturgeons and have released the animals into the Caspian Sea, hoping to get a clear picture of Caspian Sea sturgeon movement and behavior never before available. view more (2006-05-24)
Endangered sawfish focus of national collection and recovery efforts
The University of Florida, keeper of the world's shark attack records, is also now overseeing a national records collection for another toothy marine predator: the sawfish. view more (2008-12-02)
Voyages of discovery or necessity?
Ciguatera poisoning, the food-borne disease that can come from eating large, carnivorous reef fish, causes vomiting, headaches, and a burning sensation upon contact with cold surfaces. view more (2009-05-19)
Eating fish while pregnant, longer breastfeeding, lead to better infant development
Both higher fish consumption and longer breastfeeding are linked to better physical and cognitive development in infants, according to a study of mothers and infants from Denmark. Maternal fish consumption and longer breastfeeding were independently beneficial. view more (2008-09-10)
University of Alberta researchers unravel intricate animal patterns
There is a scene in the animated blockbuster "Finding Nemo" when a school of fish makes a rapid string of complicated patterns—an arrow, a portrait of young Nemo and other intricate designs. view more (2007-04-17)
