Bacterial Communities for Wastewater Treatment System

A global study expands the understanding of activated sludge microbiomes for next-generation wastewater treatment and reuse systems enhanced by microbiome engineering. Wastewater treatment and reuse ... read more

New Research Accurately Predicts Australian Wheat Yield Months Before Harvest

Topping the list of Australia's major crops, wheat is grown on more than half the country's cropland and is a key export commodity. With so much riding on wheat, accurate yield forecasting ... read more

How Sea Level Rise Affects Birds in Coastal Forests

Saltwater intrusion changes coastal vegetation that provides bird habitat. Researchers found that the transition from forests to marshes along the North Carolina coast due to climate change could ... read more

Larch trees in the permafrost forests of northeastern China -- the northernmost tree species on Earth -- are growing faster as a result of climate change. A new study of growth rings from Dahurian ... read more

Observations of herring gulls have shown how the coastal birds have developed complicated behavior to 'skin' sea creatures to make them safe to eat. Researchers think this feeding habit may ... read more

Abrupt Climate Change Drove Early South American Population Decline

Abrupt climate change some 8,000 years ago led to a dramatic decline in early South American populations, suggests new ... read more

Infrastructure development and other human-made changes have already fragmented or disrupted two-thirds of Earth's longest rivers. Dams and reservoirs are the leading contributors to ... read more

Tsunami Signals to Measure Glacier Calving in Greenland

Scientists have employed a new method utilizing tsunami signals to calculate the calving magnitude of an ocean-terminating glacier in northwestern Greenland, uncovering correlations between calving ... read more

Ocean Activity Is Key Controller of Summer Monsoons

New research finds ocean activity may control the strength and intensity of summer monsoons. The results could help researchers predict how monsoons will change with warming ... read more

Arctic Rivers Provide Fingerprint of Carbon Release from Thawing Permafrost

The feedback between a warming climate and accelerated release of carbon currently frozen into permafrost around the Arctic is one of the grand challenges in current climate research. A study used ... read more

Shipwrecks Off North Carolina, U.S. Coast Harbor Tropical Migrants

Shipwrecks and sunken structures off the North Carolina coast may act as stepping stones for tropical fish searching for favorable habitats at or beyond the edge of their normal geographic range. A ... read more

Even More Amphibians Are Endangered Than We Thought

Due to a lack of data on many amphibian species, only about 44 percent of amphibians have up-to-date assessments on their risk of extinction, compared to nearly 100% of both birds and mammals. Now, ... read more

Coral experts around the world said it was impossible to extract a multi-century record of El Niño events. But now a persistent effort has produced the world's first 400-year long record of El ... read more
