Impact of the Fukushima accident on marine life, five years later
Five years ago, the largest single release of human-made radioactive discharge to the marine environment resulted from an accident at the Fukushima Daiichi Nuclear Power Plant in Japan. Approximately 80 percent of the fallout happened over the Pacific Ocean. A new study explores the environmental consequences in the marine environment of the accident. It outlines the status of current research about the impact of the fallout on plant and animal life and what remains to be done as the radioactivity continues to spread.

Local fidelity key to ocean-wide recovery of humpback whales
Humpback whales can migrate thousands of miles to reach feeding grounds each year, but a new study concludes that their fidelity to certain local habitats -- as passed on through the generations -- and the protection of these habitats are key to understanding the ultimate recovery of this endangered species.

'Robomussels' used to monitor climate change
Tiny robots have been helping researchers study how cli­mate change affects bio­di­ver­sity. These “robo­mus­sels” have the shape, size, and color of actual mus­sels, with minia­ture built-??in sen­sors that track tem­per­a­tures inside the mussel beds.

Researchers probing the beneficial secrets in dolphins' proteins
Why reinvent the wheel when nature has the answer? One researcher's natural inspiration is coming from dolphins who seem to have protective proteins that may contain clues to treatments for aging-associated diseases in humans. A recent study has found that dolphin serum contains very high levels of an antioxidant protein.

Study reveals corals' influence on reef microbes
As they grow, corals are bathed in a sea of marine microbes, such as bacteria, algae, and viruses. While these extremely abundant and tiny microorganisms influence coral communities in a variety of ways, a new study reveals that corals also have an impact on the microbes in waters surrounding them.

Jellyfish help scientists to fight food fraud
Animals feeding at sea inherit a chemical record reflecting the area where they fed, which can help track their movements, according to a new study.

Unconventional cell division in the Caribbean Sea
Bacteria are immortal as long as they keep dividing. For decades it has been assumed that a continuous, proteinaceous ring is necessary to drive the division of most microorganisms. An international team of researchers has revealed that the symbiont of the marine roundworm breaks the ring dogma and divides without.

Iranian coastal waters: New home to a rarely seen venomous sea snake
Günther's sea snake (Microcephalophis cantoris), a rarely seen venomous sea snake with distribution thought to stretch from the Malay Peninsula to Pakistan, has now been recorded from Iranian coastal waters off the western Gulf of Oman, more than 400 kilometers away from the westernmost boundary of its previously known range.

Climate change may benefit native oysters, but there's a catch
Amid efforts to restore native oyster populations on the West Coast, how are oysters expected to fare under climate change in the decades and centuries to come? Not too badly, according to a study, but there’s a big “if” involved.

Assessing the effects of human-caused activities on marine mammals
Rising levels of noise in the ocean have been identified as a growing concern for the well-being of marine mammals, but other threats such as pollution, climate change, and prey depletion by fisheries may also harm marine mammals and influence their response to additional noise. Current knowledge and data are insufficient to determine what combination of factors cause the greatest concern, says a new report.

Uranium levels in deep sea coral reveal new insights into how the major northern ice sheets retreated
Scientists examining naturally occurring uranium levels in ancient deep sea corals have discovered new insights into how the major northern ice sheets retreated during the last major deglaciation on Earth.

Scientists search for regional accents in cod
Fish may have regional accents and communicate differently in different parts of the world, according to a fish expert.

As oceans warm, coral reef fish might prefer to move rather than adapt
Scientists have new evidence that coral-reef fish -- who are capable of adapting to warmer temperatures brought about by global climate change -- will probably opt instead to relocate to cooler parts of the ocean. In experiments using a fish found in coral reefs around the world, the blue-green damselfish, researchers found that the fish were capable of adapting to living in water 2-4 degrees Celsius above their normal summer temperatures; however, when given the slightest chance, the fish moved to cooler water.

Environmental change drove diversity in Lake Malawi cichlids
Periods of deep, clear water in Lake Malawi over the past 800,000 years coincide with bursts of species diversification, researchers show in a new report.

Examining the social networks of sharks
Researchers studied the “social networks” of sand tiger sharks and found they spend a surprising amount of time together. The findings will assist future efforts to identify places where human impacts may be affecting one portion of the sand tiger life cycle disproportionately.

Global warming collapses symbiotic gut bacteria, killing host insects
A new study shows that when heat-susceptible bacteria living symbiotically in the guts of insects are exposed to increased temperatures, both the bacteria and the insect are negatively impacted and can die. The study illustrates another way global warming will wreak havoc on life as we know it, setting off deleterious chain reactions among organisms living in symbiosis.

Rising ocean temperatures impacting human health
Rising sea surface temperatures are causing marine-related tropical diseases and harmful algal blooms to spread towards the poles, a shift that is impacting human health, according to a chapter from a new report.

Extensive deep coral reefs in Hawaii harbor unique species and high coral cover
Researchers has completed a comprehensive investigation of deep coral-reef environments throughout the Hawaiian Archipelago. The study spanned more than two decades and the researchers documented vast areas of 100% coral-cover at depths of 50-90 meters extending for tens of square kilometers, discovering that these deep-reef habitats are home to many unique species.

Help for fishing vessels to locate their catch
Big Data means that professional fishermen will soon be getting their own decision-making tool. It will tell them where fish shoals are located, and how their vessels can be operated as economically as possible, report researchers.

Fossil from oldest ancestor of modern sea turtles
The earliest ancestors of modern sea turtles may have come from the Deep South in the United States, new evidence suggests. Working with two relatively complete turtle skeletons, the fossils help solve a long-standing debate as to whether this animal was a unique species. They also provide insights into the evolutionary history of living species of sea turtles, including the Kemp's Ridley, Loggerhead and the endangered Green sea turtle.
