Hypoxic dead zones found in urban streams, not just at the coast

Tue, 11 Dec 2018 14:46:44 EST ~ A new study finds that hypoxic dead zones occur in nutrient-laden urban streams, not just in coastal waters. The research shows that intense storm flows can erode some stream channels to become a series of pools that trap nutrient-laden runoff. The elevated nutrient levels in the water spur greater consumption of dissolved oxygen by bacteria, causing the pools to become hypoxic until the next storm flushes them out. Find out more...

Stop sterilizing your dust

Tue, 11 Dec 2018 13:33:14 EST ~ A new study has found that an antimicrobial chemical called triclosan is abundant in dust -- and linked to changes in its genetic makeup. The result is dust with organisms that could cause an antibiotic-resistant infection. Find out more...

Warming, sea-ice loss: Arctic Report Card tracks region's environmental changes

Tue, 11 Dec 2018 12:11:07 EST ~ NOAA's annual report card on the Arctic, released today, shows that the Arctic region experienced the second-warmest air temperatures ever recorded; the second-lowest overall sea-ice coverage; lowest recorded winter ice in the Bering Sea; and earlier plankton blooms due to early melting of sea ice in the Bering Sea.

Possible connection between cardiovascular disease and living near oil and gas wells

Tue, 11 Dec 2018 11:29:28 EST ~ Researchers have found a possible connection between the intensity of oil and gas exploration in an area and early indicators of cardiovascular disease among nearby residents. Find out more...

Fighting smog supports solar power

Thu, 06 Dec 2018 11:59:40 EST ~ Model calculations by researchers show that if China fought smog more aggressively, it could massively increase solar power production. Find out more...

Report reveals link between air pollution and increased risk for miscarriage

Wed, 05 Dec 2018 15:22:06 EST ~ Researchers found women living along the Wasatch Front -- the most populous region in the state of Utah -- had a higher risk (16 percent) of miscarriage following short-term exposure to elevated air pollution. Find out more...

Wind power vulnerable to climate change in India

Wed, 05 Dec 2018 14:27:03 EST ~ The warming of the Indian Ocean, caused by global climate change, may be causing a slow decline in wind power potential in India, according to a new study. Find out more...

Dirty air now could harm hearts of offspring later

Wed, 05 Dec 2018 13:40:09 EST ~ A parent's exposure to dirty air before conception might spell heart trouble for the next generation, a new animal study suggests. Find out more...

Pollution: New ammonia emission sources detected from space

Wed, 05 Dec 2018 13:39:48 EST ~ Researchers have prepared the first global map of the distribution of atmospheric ammonia (NH3) by analyzing measurements taken by satellites between 2008 and 2016. The IASI interferometer allowed them to catalog more than 200 ammonia sources, two-thirds of which had never been identified before. These sources are essentially sites of intensive livestock production and industrial activity. Find out more...

Global carbon dioxide emissions rise even as coal wanes and renewables boom

Wed, 05 Dec 2018 13:39:45 EST ~ Renewable energy capacity has hit record levels and global coal use may have already peaked. But the world's carbon dioxide emissions from fossil fuels increased in 2018, and the trend places global warming targets in jeopardy. Find out more...
