Despite broad "dolphin safe" practices, fishing activities have continued to restrict the growth of at least one Pacific Ocean dolphin population, a new report has concluded. View the full article

In 1936, zoologist Sir James Gray observed dolphins swimming faster than 20 mph, but his studies had concluded that the muscles of dolphins simply weren't strong enough to support that speed. The conundrum came to be known as "Gray's Paradox." For decades the puzzle prompted much speculation and conjecture in the scientific community. But now, armed with cutting-edge flow measurement technology, researchers have tackled the problem and conclusively solved Gray's Paradox. View the full article

Researchers are fighting to remove mercury from the environment. Mercury-containing pressure gauges in the natural gas fields, coal-fired power plants and chlorine plants are among the sources of mercury that concern scientists. View the full article

A new study, which confirms significant ocean acidification across much of the Caribbean and Gulf of Mexico, reports strong natural variations in ocean chemistry in some parts of the Caribbean that could affect the way reefs respond to future ocean acidification. View the full article

Groove-like tracks on the ocean floor made by giant deep-sea single-celled organisms could lead to new insights into the evolutionary origin of animals, according to biologists. View the full article

While global-warming-induced coastal flooding moves populations inland, the changes in sea level will affect the salinity of estuaries, which influences aquatic life, fishing and recreation. View the full article

Scientists now explain the remarkable ability of marine zooplankton to swim towards light. A new study reveals how simple eyes of only two cells, sense the direction of light and guide movement towards it. The research also provides new insights into what the first eyes in animal evolution might have looked like and what their function was. View the full article

A joint project between the Irish fishing industry and scientists to track stocks of cod in the Celtic Sea is starting to yield interesting results. Over the last two years, 4,063 cod have been tagged and released in the Celtic Sea by scientists working aboard commercial fishing vessels from Dunmore East. The project is designed to study the growth and migration of both the inshore juvenile component and the offshore adult spawning component of the stock. View the full article

Researchers have developed a simple and quick method for detecting mercury in fish and dental samples, two substances at the center of public concern about mercury contamination. The technique involves a fluorescent substance that glows bright green when it comes into contact with oxidized mercury. View the full article

Fiber optics as light conductors are obviously not just a recent invention. Sponges (Porifera), the phylogenetically oldest, multicellular organisms (Metazoa) are able to transduce light inside their bodies by employing amorphous, siliceous structures. Already more than ten years ago, the finding of photosynthetically active organisms inside sponges raised the question, how they could survive there in an otherwise presumably dark space. As early as that time, marine biologists have hypothesized, that light might be transferred inside the sponge body. View the full article

Scientists have made an enormous advance in understanding Puerto Rico's most remarkable ecosystems by conducting the first comprehensive study of the island's freshwater fish species. Many of these species "are hidden gems that have been largely ignored," the scientist who led the research said. View the full article
