NASA sees 10-mile-high thunderstorms in Hurricane Henriette
NASA's TRMM satellite peered into the clouds of Hurricane Henriette as is continues moving through the Eastern Pacific Ocean, and found powerful thunderstorms that topped 10 miles high.

Strangers invade the homes of giant bacteria
Life is not a walk in the park for the world's largest bacteria, that live as soft, noodle-like, white strings on the bottom of the ocean depths. Without being able to fend for themselves, they get invaded by parasitic microorganisms that steal the nutrition, that they have painstakingly retrieved. This newly discovered bizarre deep ocean relationship may ultimately impact ocean productivity, report researchers from University of Southern Denmark now in the scientific journal Nature.

EARTH: Hurricane hunters fly toward improved storm forecasts
As hurricanes hit US coastlines, scientists study them to improve forecasts critical for saving lives and property. Last year, unmanned aircraft from NASA flew into the biggest storms as part of a project to improve hurricane forecasts. Three projects in particular may be responsible for a 20 percent error reduction in the hurricane track and intensity forecasts.

Scientists discover key to easing aquaculture's reliance on wild-caught fish
For the first time scientists have been able to develop a completely vegetarian diet that works for marine fish raised in aquaculture, the key to making aquaculture a sustainable industry as the world's need for protein increases. "This makes aquaculture completely sustainable," said Dr. Allen Place. "The pressure on natural fisheries in terms of food fish can be relieved. We can now sustain a good protein source without harvesting fish to feed fish."

Dolphins keep lifelong social memories, longest in a non-human species
Dolphins can recognize their old tank mates' whistles after being separated for more than 20 years -- the longest social memory ever recorded for a non-human species.

ORNL research reveals new challenges for mercury cleanup
More forms of mercury can be converted to deadly methylmercury than previously thought, according to a study published Sunday in Nature Geoscience. The discovery provides scientists with another piece of the mercury puzzle, bringing them one step closer to understanding the challenges associated with mercury cleanup.

Tom Bowman's Climate Report delves into Arctic methane controversy
Tom Bowman, climate science communications expert and host of the Climate Report with Tom Bowman, interviews economist Chris Hope and oceanographer Peter Wadhams, two of the three authors of an article in the journal Nature that has stirred scientific controversy. The authors modeled the economic impact of a single phenomenon of global warming -- the release of methane from thawing permafrost beneath the East Siberian Sea -- and concluded that it "comes with an average global price tag of $60 trillion."

Seafood menus from Hawaii reflect long-term ocean changes
The colorful restaurant menus that thousands of tourists bring home as souvenirs from Hawaii hold more than happy memories of island vacations. They also contain valuable data that are helping a trio of researchers track long-term changes to important fisheries in the Aloha State.

Disappearance of coral reefs, drastically altered marine food web on the horizon
If history's closest analog is any indication, the look of the oceans will change drastically in the future as the coming greenhouse world alters marine food webs and gives certain species advantages over others.

Carbon emissions to impact climate beyond the day after tomorrow
Future warming from fossil fuel burning could be more intense and longer-lasting than previously thought. This prediction emerges from a new study by Richard Zeebe at the University of Hawai'i who includes insights from episodes of climate change in the geologic past to inform projections of man-made future climate change. The study is published in the Proceedings of the National Academy of Sciences.

UCSB study finds climate change is causing modifications to marine life behavior
Oceans cover 71 percent of the Earth's surface, yet our knowledge of the impact of climate change on marine habitats is a mere drop in the proverbial ocean compared to terrestrial systems. An international team of scientists set out to change that by conducting a global meta-analysis of climate change impacts on marine systems.

The River Odra mouth area's biological diversity explained in new open access books
The Great Lagoon is the major component in the Odra River mouth system. The border between Poland and Germany crosses the Szczecin Lagoon, leaving the Great Lagoon on the Polish side. In addition to supporting highly efficient commercial fisheries, the Szczecin Lagoon is a popular recreation and tourist area. This new books provids groundwork for a comprehensive assessment of the Great Lagoon's environment and biota, and for a multi-component analysis of the Lagoon's ecosystem.

Decoding material fluxes in the tropical ocean
For the first time, oceanographers at GEOMAR Helmholtz Centre for Ocean Research Kiel were able to make quantitative statements regarding this question. They showed that about one-third of the oxygen supply in these areas is provided by turbulent processes, such as eddies or internal waves. The study was just published in the international journal Biogeosciences.

Geoscientists unearth mineral-making secrets potentially useful for new technologies
Proteins have gotten most of the attention in studies of how organic materials control the initial step of making the first tiny crystals that organisms use to build structures that help them move and protect themselves. Virginia Tech researchers have discovered that certain types of sugars, known as polysaccharides, may also control the timing and placement of minerals that animals use to produce hard structures.

Arctic sea-ice loss has widespread effects on wildlife
How the Arctic wildlife and humans will be affected by the continued melting of Arctic sea ice is explored in a review article in the journal Science, by an international team of scientists. The article examines relationships among algae, plankton, whales, and terrestrial animals such as caribou, arctic foxes, and walrus; as well as the effects of human exploration of previously inaccessible parts of the region.

Ancient whale coprolites, fault slickensides, shergottites, Ediacara, and Cascadia
Two new Geology articles this month are open access: "Steady rotation of the Cascade arc" and "Silica gel formation during fault slip: Evidence from the rock record." Other new articles cover everything from the discovery of fossilized whale "intestinal products" in central Italy to flooding as a result of the 2010 Eyjafjallajökull volcano eruption to new findings via the Compact Reconnaissance Imaging Spectrometer for Mars to using microfossils to reconstruct massive earthquakes in Cascadia.

Robots strike fear in the hearts of fish
The latest in a series of experiments testing the ability of robots to influence live animals shows that bio-inspired robots can not only elicit fear in zebrafish, but that this reaction can be modulated by alcohol. These findings may pave the way for new methodologies for understanding anxiety and other emotions, as well as substances that modulate them.

Hide, ambush, kill, eat: The giant water bug Lethocerus patruelis kills a fish
The largest European water insect Lethocerus patruelis, commonly known as giant water bug, can reach the impressive size of up to 8 cm in length. A recent study, published in the open access journal Zookeys, provides detailed information on karyotype and the reproductive system of the species. The study also presents a rare opportunity to see their vicious predatory practices, catching a giant water bug larva attacking and killing a small fish on video.
