Dolphin-power sufficient for propulsion without tricks
For 60 years the world has believed that dolphins did not have enough muscle to propel them at high speed and that they were resorting to some fluid-flow trickery to pull off their impressive performance. But Frank Fish from West Chester University, USA, never believed it and now he has proved that not only do dolphins have sufficient muscle power, but also they routinely produce ten times more power than the fittest human athletes.

Bacterial 'syringe' necessary for marine animal development
Bacterial biofilms serve a vital purpose, flagging suitable homes for some marine organisms and actually aiding the transformation of larvae to adults. A new study at the California Institute of Technology is the first to describe a mechanism for this phenomenon, providing one explanation for the relationship between bacterial biofilms and the metamorphosis of marine invertebrates. This information could provide key insights for the prevention of biofouling organism growth on the hulls of ships.

NASA sees Tropical Cyclone Colin coming 'unwound'
Tropical Cyclone Colin is not as tightly wrapped as it was a day ago. Satellite imagery from NASA's Aqua and TRMM satellites show Colin is not as organized as it was.

NASA adds up Tropical Cyclone Colin's rainfall rates
Tropical Cyclone Colin continued moving through the Southern Indian Ocean on Jan. 13, and the Tropical Rainfall Measuring Mission calculated the rates in which rain was falling throughout the storm.

NASA's infrared satellite imagery shows wind shear affecting Cyclone Ian
Tropical Cyclone Ian has been battered by wind shear and infrared imagery from NASA's Aqua satellite revealed that the bulk of the precipitation has been pushed east and southeast of the storm's center.

Marine tubeworms need nudge to transition from larvae state
Biofouling is the process by which barnacles, muscles, oysters, and tubeworms accumulate on the bottom of boats and other surfaces. Researchers at the University of Hawai'i at Mānoa and Caltech have discovered a biological trigger behind the buildup. Biofouling begins when floating marine larvae come into contact with a biofilm formed by a microbe. Now researchers have isolated the genetic underpinnings of this novel form of bacterium-animal interaction.

Loss of large carnivores poses global conservation problem
In ecosystems around the world, the decline of large predators such as lions, dingoes, wolves, otters, and bears is changing the face of landscapes from the tropics to the Arctic -- but an analysis of 31 carnivore species published today in the journal Science shows for the first time how threats such as habitat loss, persecution by humans and loss of prey combine to create global hotspots of carnivore decline.

Radiocarbon dating suggests white sharks can live 70 years and longer
Adult white sharks may live far longer than previously thought, according to a new study that used radiocarbon dating to determine age estimates for white sharks, also known as great whites, in the Northwest Atlantic Ocean. This first successful radiocarbon age estimate study analyzed vertebrae samples from eight white sharks; the oldest male was 73, the oldest female 40, suggesting previous studies have significantly underestimated longevity in sharks.

GPS traffic maps for leatherback turtles show hotspots to prevent accidental fishing deaths
Pacific leatherback turtles, among the most endangered animal populations in the world, often die hooked or tangled in industrial longlines that set thousands of hooks in the ocean to catch fish. In a new study in the Proceedings of the Royal Society B, researchers show the use-intensity distributions for 135 satellite-tracked adult turtles and distributions of longline fishing effort in the Pacific Ocean. The overlap of these distributions in space and time allows prediction of bycatch risk.

Coral chemical warfare: Suppressing a competitor enhances susceptibility to a predator
Competition may have a high cost for at least one species of tropical seaweed. Researchers examining the chemical warfare taking place on Fijian coral reefs have found that one species of seaweed increases its production of noxious anti-coral compounds when placed into contact with reef-building corals, but at the same time becomes more attractive to herbivorous fish.

Marine bacteria to fight tough infections
Aggressive infections are a growing health problem all over the world. The development of resistant bacteria is rampant and, in the United States, resistant staphylococci cause more deaths than AIDS on an annual basis. Researchers from the University of Copenhagen are studying a new form of treatment based on marine bacteria. The results have been published in PLOS ONE.

Researchers unveil rich world of fish biofluorescence
A team led by scientists from the American Museum of Natural History has released the first report of widespread biofluorescence in fishes, identifying more than 180 species that glow in a wide range of colors and patterns. Published today in PLOS ONE, the research shows that biofluorescence -- a phenomenon by which organisms absorb light, transform it, and eject it as a different color -- is common and variable among marine fish species, indicating its potential use in communication and mating.

Scientists to examine Pacific's 'global chimney'
NCAR scientists and partners next week launch a field project in the tropical Pacific, a remote region that holds a key to understanding worldwide climate. The warm waters fuel huge clusters of thunderstorms that act as a global chimney, lofting gases and particles into the stratosphere and affecting the planet.

Jumping snails left grounded in future oceans
Sea snails that leap to escape their predators may lose their extraordinary jumping ability because of rising carbon dioxide emissions, scientists have discovered. Lead author, Dr. Sue-Ann Watson from the ARC Centre of Excellence for Coral Reef Studies observed that the conch snail, which uses a strong foot to leap away from approaching predators, either stops jumping, or takes longer to jump, when exposed to carbon dioxide levels projected for the end of this century.
