Earliest evidence of reproduction in a complex organism
A new study of 565 million-year-old fossils has identified how some of the first complex organisms on Earth -- possibly some of the first animals to exist -- reproduced, revealing the origins of our modern marine environment.

Septic tanks aren't keeping poo out of rivers and lakes
The notion that septic tanks prevent fecal bacteria from seeping into rivers and lakes simply doesn't hold water, says a new Michigan State University study. Water expert Joan Rose and her team of water detectives have discovered freshwater contamination stemming from septic systems.

Study offers new insights on hurricane intensity, pollution transport
As tropical storm Isaac was gaining momentum toward the Mississippi River in August 2012, University of Miami researchers were dropping instruments from the sky above to study the ocean conditions beneath the storm. The newly published study showed how a downwelling of warm waters deepened the storm's fuel tank for a rapid intensification toward hurricane status. The results also revealed how hurricane-generated currents and ocean eddies can transport oil and other pollutants to coastal regions.

Bering Sea hotspot for corals and sponges
North of the Aleutian Islands, submarine canyons in the cold waters of the eastern Bering Sea contain a highly productive 'green belt' that is home to deep-water corals as well as a plethora of fish and marine mammals.

Studying killer whales with an unmanned aerial vehicle
Last year, for the first time, scientists used an unmanned aerial vehicle to photograph killer whales from above, giving scientists a new way to monitor killer whale health while giving us all a stunning new view of the species. In a recent article in the Journal of Unmanned Vehicle Systems, scientists explain how they configured the UAV into a precision scientific instrument.

BMC Ecology Image Competition 2015 winners announced
This year's BMC Ecology Image Competition includes photos showing a Palestinian sunbird's careful maneuvers, endangered storks foraging in a garbage dump and a pregnant bat in mid-flight. The 32 images showcase a diverse range of interspecies relationships, from seemingly-unlikely symbiotic partnerships, to the perilous world of predation and carnivorous plants.

Treating ships' ballast water: Filtration preferable to disinfection
Untreated ballast water discharge from ships can spread living organisms and even pathogens across the world thereby introducing non-native or invasive species into the local environment. Scientists at Helmholtz Zentrum München therefore recommend using physical treatment processes such as filtration rather than electrochemical disinfection, which creates countless potentially toxic compounds. These are the findings of a recent study published in the journal Environmental Science and Technology.

Scientists urge ban on salamander imports to fend off deadly fungus
California amphibian experts warn that a recently discovered fungus already devastating salamanders in Europe could imperil American salamanders, and urge the US Fish and Wildlife Service to immediately halt salamander imports until there is a plan to detect and prevent spread of the fungus. SF State University, UC Berkeley and UCLA biologists say the fungus, dubbed Bsal, is worse than the Bd chytrid fungus that has brought more than 200 amphibian species worldwide near extinction.

New study exposes negative effects of climate change on Antarctic fish
Scientists at University of California Davis and San Francisco State University have discovered that the combination of elevated levels of carbon dioxide and an increase in ocean water temperature has a significant impact on survival and development of the Antarctic dragonfish (Gymnodraco acuticeps). The research article was published today in the journal Conservation Physiology.

Nature has more than one way to grow a crystal
The findings in the journal Science have implications for questions regarding how animals and plants grow minerals into shapes that have no relation to their original crystal symmetry, and why some contaminants are difficult to remove from stream sediments.

Study of 'senior citizen' marine snails uncovered how nerve cells fail during learning
A new research study on marine snails uncovered the first cells in the nervous system to fail during aging. The University of Miami Rosenstiel School of Marine and Atmospheric Science researchers' findings are important to better understanding the underlying mechanisms of age-related memory loss in humans.

Boxfish shell inspires new materials for body armor and flexible electronics
The boxfish's unique armor draws its strength from hexagon-shaped scales and the connections between them, engineers at the University of California, San Diego, have found. They describe their findings and the carapace of the boxfish (Lactoria cornuta) in the July 27 issue of the journal Acta Materialia. Engineers also describe how the structure of the boxfish could serve as inspiration for body armor, robots and even flexible electronics.

Past and present sea levels in the Chesapeake Bay Region, USA
In a new article for GSA Today, authors Benjamin DeJong and colleagues write that sea-level rise (3.4 mm/yr) is faster in the Chesapeake Bay region than any other location on the Atlantic coast of North America, and twice the global average (1.7 mm/yr). They have found that dated interglacial deposits suggest that relative sea levels in the Chesapeake Bay region deviate from global trends over a range of timescales.

Endangered icebreakers: The future of Arctic research, exploration and rescue at risk
The United States' Icebreaker Fleet -- operated by the US Coast Guard -- consists of just two ships that are used for everything from search and rescue to national security operations to scientific research. Examine the various roles icebreakers play, especially in Arctic research, and how insufficient funding is affecting the icebreakers' roles.

Humpback whale recovery in Australia -- A cause for celebration
Australia has one of the highest rates of animal species that face extinction in the world. However, over the last decade, there have been animals that are rebounding. One example is the conservation success story of the recovery of the humpback whales that breed in Australian waters. This new study, published in Marine Policy, reviews data collected in past studies and proposes a revision of the conservation status for humpback whales found in Australian waters.

FAU to develop unmanned marine vehicles for bridge inspections
Florida has approximately 11,450 bridges and inspecting and maintaining them is arduous, especially since so many of them span rivers, canals and saltwater areas. Researchers at FAU have received a grant from the Florida Department of Transportation to develop unmanned marine vehicles for on-water bridge inspections. Unlike manned vessels, which are continuously teleoperated by a human user, unmanned surface vehicles are capable of operating autonomously without human intervention for prolonged periods of time.

Plant light sensors came from ancient algae
The light-sensing molecules that tell plants whether to germinate, when to flower and which direction to grow to seek more sunlight were inherited millions of years ago from ancient algae, finds a new study from Duke University. The findings are some of the strongest evidence yet against the prevailing idea that the ancestors of early plants got the red light sensors that helped them move from water to land by engulfing bacteria, the researchers say.

Marine plankton brighten clouds over Southern Ocean
New research using NASA satellite data and ocean biology models suggests tiny organisms in vast stretches of the Southern Ocean play a significant role in generating brighter clouds overhead. Brighter clouds reflect more sunlight back into space affecting the amount of solar energy that reaches Earth's surface, which in turn has implications for global climate. The results were published July 17 in the journal Science Advances.

Parasitic flatworms flout global biodiversity patterns
The odds of being attacked and castrated by a variety of parasitic flatworms increases for marine horn snails the farther they are found from the tropics. A Smithsonian-led research team discovered this exception to an otherwise globally observed pattern -- usually biodiversity is greatest in the tropics and decreases toward the poles.
