Scientists from the Smithsonian and colleagues have found that waterbird communities can be the “canary in the coal mine” when it comes to detecting the health of urban estuary ecosystems. Their research revealed that the types of waterbirds that inhabit urban estuaries are influenced not only by urban development, but also by a far more natural process―rain. The team’s findings are published in the scientific journal PLoS ONE.

A new study finds surface water samples are insufficient in determining the prevalence of plastic debris in oceans.
The Near Earth Object Media/Risk Communications Working Group Report has been issued by Secure World Foundation. To deal with potentially hazardous Near Earth Objects (NEOs) that could strike the Earth, there is need to establish an effective international communications strategy - but doing so is a daunting task, one that demands effective use of mass communication tools.
By correlating weather factors like temperature, rain and snowfall, Elena Naumova, Ph.D., professor of civil and environmental engineering at Tufts School of Engineering, is able to predict the timing and intensity of rotavirus, a disease that causes extreme diarrhea, dehydration and thousands of death annually, particularly among children. Her research focused on one of the hardest-hit regions of the world, South Asia.
A dilemma is smouldering-- even as wildfires top the current headlines. New research highlights the practice of aggressive fire suppression by using studies at Lake Tahoe as an active example.
Super-eruptions are potentially civilization-ending events and new research suggests that they may have surprisingly short fuses.
New research shows some of the steepest mountain slopes in the world got that way because of the interplay between terrain uplift associated with plate tectonics and powerful streams cutting into hillsides, leading to large landslides.
A chance discovery of 80-year-old photo plates in a Danish basement is providing new insight into how Greenland glaciers are melting today.
Materials scientist Yun Hang Hu has discovered a chemical reaction that gobbles up the greenhouse gas carbon dioxide and produces a couple of useful compounds. And, by the way, it releases energy.
Recent surveys by researchers at the Virginia Institute of Marine Science (VIMS) reveal an unprecedented number of young scallops in two fishery management areas off the mid-Atlantic coast. The results bode well for the continued success of the commercial fishery.
Sandia modeling study contradicts a long-held belief of geologists that pore sizes and chemical compositions are uniform throughout a given strata, which are horizontal slices of sedimentary rock. By understanding the variety of pore sizes and spatial patterns in strata, geologists can help achieve more production from underground oil reservoirs and water aquifers. Better understanding also means more efficient use of potential underground carbon storage sites, and better evaluations of the possible movement of radionuclides in nuclear waste depositories to determine how well the waste will be isolated.
When leatherback turtle hatchlings dig out of their nests buried in the sandy Playa Grande beach in northwest Costa Rica, they enter a world filled with dangers. This critically endangered species faces threats that include egg poaching and human fishing practices. Now, Drexel University researchers have found that the climate conditions at the nesting beach affect the early survival of turtle eggs and hatchlings. They predict, based on projections from multiple models, that egg and hatchling survival will drop by half in the next 100 years as a result of global climate change.
Study brings better understanding to atmospheric maladies such as particulate matter, which can cause health problems in the very young and old, as well as other problems.
New fish-tagging studies of young bluefin tuna in the Atlantic off New England are offering the first fishery-independent, year-round data on dispersal patterns and habitat use for the popular game fish. Miniaturized pop-up satellite tags suitable for smaller fish helped make the research possible.
/PRNewswire-USNewswire/ -- As the popularity of marine aquariums rises, so does the demand for wildlife inhabiting them. Most aquarium fish are harvested from their natural habitats – primarily coral reefs – and imported into the United States by the millions annually.
