The health risks posed by mercury contaminated fish is sufficient to warrant issuing a worldwide general warning to the public - especially children and women of childbearing age-to be careful about how much and which fish they eat. That is one of the key findings comprising "The Madison Declaration on Mercury Pollution" published today in a special issue of the international science journal Ambio.

For years, anglers thinking they were catching the prized white marlin may have caught something quite different, raising concerns about the true remaining numbers of the threatened species, according to an article in the most recent issue of the scientific journal Bulletin of Marine Science.

To find prey and avoid being preyed upon, fish rely on a row of specialized sensory organs along the sides of their bodies, called the lateral line. Now, a research team led by Chang Liu at the University of Illinois at Urbana-Champaign has built an artificial lateral line that can provide the same functions in underwater vehicles.

Even at the best of times, the West's water supplies are fraught with political, economic and environmental wrangling. When devastating droughts occurred in the 1970s and the 2000s, farmers and fish alike suffered. Yet the ability to predict stream flows in the Western United States at seasonal lead times - months or longer - is scarcely better today than it was in the 1960s.

A new statistical method of determining genetic traits that influence social interactions among animals may provide for more productive livestock.

Right now some tubeworm tartare and clams on the half shell would really hit the spot, so you're headed for the all-night café. "All-night" being the operative word because the volcanic ridge you're tooling along is nearly 1.5 miles below the surface.

For the first time in U.S., and probably global, history a fish identified as endangered has been shown to have recovered - and in the Hudson River, which flows through one of the world's largest population centers, New York City

Working in rocks more than 70 million years old far above the Arctic Circle, paleontologists discovered a remarkable new fossil species that is the most compelling evidence yet of an intermediate stage between fish and early limbed animals.

Frogs, newts, lizards and some fish can grow new parts -- why not people?

Ongoing global climate change causes changes in the species composition of marine ecosystems, especially in shallow coastal oceans

New hope for commercial fisheries? Quite the opposite, a good catch doesn't necessarily mean that depleted stocks have recovered
