A study in the Marcellus Shale region of western Pennsylvania has shown that even after being treated, wastewater from hydraulic fracturing operations left significant contamination in a waterway downstream of treatment plants. 

Researchers from Penn State University, Colorado State University, and Dartmouth College studied sediments from Conemaugh River Lake — a dammed reservoir east of Pittsburgh — and found that they were contaminated with endocrine-disrupting chemicals called nonylphenol ethoxylates; polycyclic aromatic hydrocarbons, which are carcinogens; and elevated levels of radium. 

Forest birds on the island of Hawaii are responding positively to being restored in one of the largest, ongoing reforestation projects at Hakalau Forest National Wildlife Refuge, according to a new study released July 10 in the journal Restoration Ecology.

Serving as pollinators and seed dispersers, birds have an important role in ecosystem function and their presence in restoration areas can be a measure of success for conservation efforts.

Projections of Future Beach Loss in Japan Due to Sea-Level Rise and Uncertainties in Projected Beach Loss

An international research team has discovered that anywhere from 25 to 100 billion failed stars reside in the Milky Way Galaxy. The Milky Way Galaxy is the celestial home to Earth.

The failed stars, which are known as Brown dwarfs, are astronomical entities that are too large to be planets and too small to be stars.

Could the storms that once engulfed the Great Plains in clouds of black dust in the 1930’s once again wreak havoc in the U.S.? A new statistical model developed by researchers at Princeton University and the National Oceanic and Atmospheric Administration (NOAA) predicts that climate change will amplify dust activity in parts of the U.S. in the latter half of the 21st century, which may lead to the increased frequency of spectacular dust storms that have far-reaching impacts on public health and infrastructure.
