Oceanographers find that mercury levels in pelagic fish found around Hawaii are influenced by depth.
-
Researchers have developed a new, more efficient way of cloning zebra fish, a breakthrough that could have implications for human health research.
-
Group B Streptococcus is a versatile pathogen that affects a variety of animals. Now studies are revealing new information about this pathogen.
-
Scientists have just completed an unprecedented journey into the vast and little-explored "Great Pacific Ocean Garbage Patch." The researchers encountered a large amount of debris including a large net entwined with plastic and various marine organisms.

Biophysicists in Germany are leading an effort to develop and apply models of the so-called lateral-line system found in fish and some amphibians. This sensory organ enables an animal, even in murky water, to map its surroundings and recognize other animals. In a new study, the researchers report mathematical models that capture essential elements of the system, agree with experimental data, and could be easy to implement technically, as in robots.

A novel natural product yields potential new ways to fight diseases. Researchers have deciphered the highly unusual molecular structure of a naturally produced, ocean-based compound that is giving new understanding of the function of mammalian nerve cells.
-
The green mussel is known for being a notoriously invasive fouling species, but scientists have just discovered that it also has a very powerful form of adhesion in its foot. The stickiness of the mussel's foot could possibly be copied to form new man-made adhesives.

Fast growing transgenic fish can revolutionize commercial fish farming and relieve the pressure on overexploited fish stocks. But what happens in the natural environment if transgenic fish escape? Researchers in Sweden have studied transgenic fish on behalf of the European Union and are urging caution.

Scientists from the U.S. have teamed up with Israeli and Jordanian researchers to protect the Gulf of Aqaba, a strategic waterway whose fragile marine ecosystem is vital to both Israel and Jordan. Participants in the NATO-funded project say they are bridging the Arab-Israeli political divide for the sake of science, peace and environmental conservation.

Watermelon juice can be a valuable source of biofuel. Researchers have shown that the juice of reject watermelons can be efficiently fermented into ethanol.
-
Marine biologists have shown that young lemon sharks born in Bimini, Bahamas, tend to stay near their coastal birthplace for many years. Knowledge about these intermediate-aged animals -- the breeders of tomorrow -- has been limited. Thus, tropical island-nations that sacrifice their nursery habitats to coastal development are therefore likely to lose both babies and much older sharks, with potentially dire effects on the surrounding ecosystem.

During a cave diving expedition to explore the Tunnel de la Atlantida, the world's longest submarine lava tube on Lanzarote in the Canary Islands, a team of scientists and cave divers have discovered a previously unknown species of crustacean, belonging to the remipede genus Speleonectes.
-
A team of German and British scientists have used fossilised shark teeth to reconstruct the climate of the North Sea during the Palaeogene period, between 40 and 60 million years ago. The results suggest that the North Sea was for a brief period isolated from surrounding oceans, resulting in surface-water freshening and a significant reduction in the diversity of life.
-
In the latest proof that the oceans continue to offer remarkable findings and much of their vastness remains to be explored, scientists have discovered a unique group of worms that live in the depths of the ocean. Orbs lobbed by the mysterious worms burst into brilliant light, thought to be a defensive measure.
-
The oldest complex life forms -- living in nutrient-rich oceans more than 540 million years ago -- likely fed by osmosis, new research shows.
-
The results of a Wildlife Conservation Society study that rapidly measures stream habitat have been adopted by a government agency working with private landowners to restore waterways throughout the US.

Gary Lindner and Russ Kikel at AmericanReef.com this month bring you another podcast, this one dealing with sexual and asexual coral reproduction.

Terry discusses how to make a donation to our magazine and about setting up his other tank as a freshwater system.
-
Substrates, oh the dilemma!
-
The information presented in this installment should get you started in properly planning a project.
-
Even under the best conditions, only a small percent of the eggs ejected in a spawning event will actually get fertilized, and of those that do, maybe 5% will make it through metamorphosis, or even far fewer than that.
-
The first 6 months of 2009 have been one of the most exciting periods for the release of new reef aquarium products.
-
New observations help understand the massive blooms of microscopic marine algae -- phytoplankton -- in the seas around Madagascar and its effect on the biogeochemistry of the southwest Indian Ocean.

The same things that make Alaska's marine waters among the most productive in the world may also make them the most vulnerable to ocean acidification. According to new findings, Alaska's oceans are becoming increasingly acidic, which could damage Alaska's king crab and salmon fisheries.

Fish in US waters from Cape Hatteras to the Canadian border have moved away from their traditional, long-time habitats over the past four decades because of fundamental changes in the regional ecosystem, according to a new report. The report also points out the need to manage the waters off the northeastern coast of the United States as a whole rather than as a series of separate and unrelated components.
