Motorboat noise gives predators a deadly advantage
Biologists found that noise from passing motorboats increases stress levels in young coral reef fish and reduces their ability to flee from predators. As a consequence they are captured more easily and their survival chances are halved.

Antibiotic's killer strategy revealed
Using a special profiling technique, researchers have determined the mechanism of action of a potent antibiotic, known as tropodithietic acid, leading them to uncover its hidden ability as a potential anticancer agent.

Bachelor's paradise: Female turtles outnumbering males due to warming temps
Rising global temperatures may skew gender imbalance among the marine turtle population, according to new research. The sex of marine hatchlings is influenced by incubating temperatures, and warmer temperatures produce a higher number of female hatchlings.

Safeguarding sturgeon
Researchers are one step closer to developing an online map that would help Mid-Atlantic fishermen avoid catching Atlantic sturgeon. The team found they could make useful predictions about sturgeon locations using satellite measurements of ocean color and temperature.

Diatoms sense the 'odor' of stones
Diatoms are unicellular algae that are native in many waters. They are a major component of marine phytoplankton and the food base for a large variety of marine organisms. In addition, they produce about one fifth of the oxygen in the atmosphere and are therefore a key factor for our global climate. However, these algae, which measure only a few micrometers, have yet another amazing ability: they can "smell" stones.

The return of the flatworm
Where does the acoel flatworm belong in the tree of life? Biologists have discussed this question for the last 20 years. Now new research suggests that researchers have found the answer.

Modern microbial ecosystems provide window to early life on Earth
New research provides new insight into one of the world's most diverse and extensive ecosystems of living microbes. The study offers a new perspective on the growth and structure of rare, microbial reefs, called stromatolites, which are a window into the emergence and evolution of life on Earth.

Four new deep-sea worm species discovered
Four newly discovered species living near deep-sea cold seeps, hydrothermal vents, and whale carcasses off the coasts of California and Mexico are described in a new article. The new discoveries have allowed the scientists to finally stabilize the placement of the five species, all in the genus Xenoturbella, on the animal tree of life.

Warming ocean may bring major changes for US northeast fishery species
Scientists have released the first multispecies assessment of just how vulnerable U.S. marine fish and invertebrate species are to the effects of climate change. The study examined 82 species that occur off the Northeastern U.S., where ocean warming is occurring rapidly. Researchers found that most species evaluated will be affected, and that some are likely to be more resilient to changing ocean conditions than others.

Four new algae species discovered in Hawaii's deep waters
Scientists have announced the discovery of four new species of deep-water algae in Hawaii's Papahanaumokuakea Marine National Monument. The new species were collected between 200-400 feet, depths not typically known for marine algae.

A new alternative to sodium: Fish sauce
Vietnamese fish sauce added to chicken broth, tomato sauce and coconut curry reduced the amount of sodium chloride by by 10-25 percent while still maintaining the perceived deliciousness, saltiness and overall flavor intensity.

Cling-on warriors: Sandcastle worms serve as inspiration for a new type of underwater adhesive
An interdisciplinary group of researchers has made strides in the development of an underwater adhesive that has the potential for a variety of biomedical and non-biological applications.

Living a 'mixotrophic' lifestyle
Some tiny plankton may have big effect on ocean's carbon storage, report scientists. A research team has found that some microscopic, mixotrophic organisms may have a large impact on the ocean's food web and the global carbon cycle.

Ship noise extends to frequencies used by endangered killer whales
When an endangered orca is in hot pursuit of an endangered salmon, sending out clicks and listening for their echoes in the murky ocean near Seattle, does the noise from the nearby shipping lane interfere with them catching dinner? To find out, scientists measured underwater noise as ships passed their study site 3,000 times. This unprecedented characterization of ship noise will aid in the understanding of the potential effects on marine life, and help with possible mitigation strategies.

Shark with lowest-known metabolism is a sluggish success
Laziness can help you succeed… if you’re a nurse shark. A new research paper reveals that nurse sharks have the lowest metabolic rate measured in any shark — new evidence of the sluggish lifestyle that has helped the species survive for millennia.

The sound of endangered salmon surviving
With California in the fourth year of a historic drought, there is much controversy over how to supply cities, farms, and ecosystems with the water they need. Technology may help solve the puzzle.

Can animals thrive without oxygen?
In 2010, a research team garnered attention when it published evidence of finding the first animals living in permanently anoxic conditions at the bottom of the sea. But a new study raises doubts.

Land plant became key marine species
The genome of eelgrass (Zostera marina) has now been unveiled. It turns out that the plant, once land-living but now only found in the marine environment, has lost the genes required to survive out of the water.
