Illinois sportfish recovery a result of 1972 Clean Water Act, scientists report

Wed, 18 Oct 2017 12:17:06 EDT ~ Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.

Fighting fires before they spark

Tue, 17 Oct 2017 15:29:44 EDT ~ With warm, dry summers comes a deadly caveat for the western United States: wildfires. Scientists say the hot, dry climates found west of the Mississippi, along with decades of fire suppression efforts, are creating a devastating and destructive combination -- leading to fires like the ones currently burning in California. Now, new research is giving forest and fire management teams across the country the upper hand in reducing the severity of these events. Find out more...

Study shows how water could have flowed on 'cold and icy' ancient Mars

Tue, 17 Oct 2017 11:43:41 EDT ~ Research by planetary scientists finds that periodic melting of ice sheets on a cold early Mars would have created enough water to carve the ancient valleys and lakebeds seen on the planet today. Find out more...

A new way to harness wasted methane

Tue, 17 Oct 2017 11:43:28 EDT ~ Scientists have identified a process that could be used to harness methane that is now wasted by being burned off at wellheads. Find out more...

Rivers carry plastic debris into the sea

Tue, 17 Oct 2017 11:00:28 EDT ~ Every year, millions of tons of plastic debris ends up in the sea. The path taken by plastic to reach the sea must be elucidated before it will be possible to reduce the volume of plastic input. To date, there was only little information available on this. It has now been followed up by an interdisciplinary research team who were able to show that plastic debris is primarily carried into the sea by large rivers. Find out more...

Link between forest fire smoke and pollution events discovered

Mon, 16 Oct 2017 14:48:48 EDT ~ Smoke from forest fires might contribute to more than half of certain gritty air pollution events in the continental U.S. during the summer, and as much as 20 percent of those events throughout the year, according to new research. Find out more...

Cocktail tests on toxic waste called for

Mon, 16 Oct 2017 09:27:15 EDT ~ Surprisingly low concentrations of toxic chemicals -- from fungicides to antidepressants -- can change the way some aquatic creatures swim and feed, according to new research. In addition, depending on the cocktail of toxins they can produce unexpected results. Find out more...

Baltic clams, worms release as much greenhouse gas as 20,000 dairy cows

Fri, 13 Oct 2017 09:10:20 EDT ~ Ocean clams and worms are releasing a significant amount of potentially harmful greenhouse gas into the atmosphere, scientists have shown. Find out more...

Is it gonna blow? Measuring volcanic emissions from space

Thu, 12 Oct 2017 20:02:21 EDT ~ Carbon dioxide measured by a NASA satellite pinpoints sources of the gas from human and volcanic activities, which may help monitor greenhouse gases responsible for climate change. Find out more...

Combination of El Nio and 2016 Ecuador earthquake likely worsened Zika outbreak

Thu, 12 Oct 2017 20:02:02 EDT ~ A Zika virus outbreak in coastal Ecuador in 2016 was likely worsened by a strong El Nio and a magnitude 7.8 earthquake that struck the region in April, according to a new study. Find out more...
