Artificial lung to help study air pollution effects
October 23, 2015 09:11 AM - NoCamels Team, NoCamels
Air pollution is one of the leading causes of lung cancer and respiratory diseases, responsible for one in eight global deaths, according to the World Health Organisation.
However, researchers will soon be able to develop new treatments for such diseases with a life-sized, artificial human lung created at the Technion-Israel Institute of Technology in Haifa, Israel. It is the first diagnostic tool for understanding in real time how tiny particles move and behave in the deepest part of the human lungs, the alveolar tissue.
Bees don't like diesels!
October 19, 2015 04:19 PM - Staff, ClickGreen
Diesel fumes may be reducing the availability of almost half the most common flower odours that bees use to find their food, new research has found.
The new findings suggest that toxic nitrous oxide (NOx) in diesel exhausts could be having an even greater effect on bees’ ability to smell out flowers than was previously thought.
NOx is a poisonous pollutant produced by diesel engines which is harmful to humans, and has also previously been shown to confuse bees’ sense of smell, which they rely on to sniff out their food.
Volkswagen begins recalling diesels in Europe
October 19, 2015 06:54 AM - Leon Kaye
The good news for Volkswagen is that it delivered almost 7.5 million vehicles to customers during the first three quarters of 2015. The bad news is that 8.5 million of VW’s cars will most likely be subject to a mandatory recall — and that’s just in Europe.
The fallout from the Volkswagen emissions scandal continues to reverberate, four weeks after revelations about the installation of “defeat device” software in diesel-powered cars slammed the newswires. Now, the world’s largest automaker is facing a global public relations crisis. This includes its home base: 2.8 million of the recalled vehicles were sold in Germany.
EPA and the regulation of greenhouse gasses
October 16, 2015 08:43 AM - Editor, ENN
This week, EPA Administrator Gina McCarthy joined private and public sector leaders for a second annual White House roundtable discussion about the progress made and new steps taken to curb emissions of hydrofluorocarbons (HFCs), potent greenhouse gases used in refrigeration and air conditioning. Administrator McCarthy announced several new actions the agency will take to help support a smooth transition to climate-friendly alternatives to HFCs.
"EPA is working closely with industry leaders to reduce greenhouse gas emissions, transition to climate-friendly refrigerants, and deploy advanced refrigeration technologies,” said EPA Administrator Gina McCarthy. “The powerful combination of EPA’s regulatory actions and innovations emerging from the private sector have put our country on track to significantly cut HFC use and deliver on the goals of the President’s Climate Action Plan.”
Arsenic found in many US red wines
October 7, 2015 09:11 AM - Jennifer Langston, University of Washington
A new University of Washington study that tested 65 wines from America’s top four wine-producing states — California, Washington, New York and Oregon — found all but one have arsenic levels that exceed what’s allowed in drinking water.
The U.S. Environmental Protection Agency allows drinking water to contain no more than 10 parts per billion of arsenic. The wine samples ranged from 10 to 76 parts per billion, with an average of 24 parts per billion.
Outsourcing manufacturing to China and the climate
October 6, 2015 07:40 AM - Belfer Center for Science and International Affairs, Harvard Kennedy School
In a study published today in the journal Nature Climate Change, scientists from three universities demonstrate that buying a product made in China causes significantly higher carbon dioxide emissions than purchasing the same product made elsewhere. The study, titled "Targeted opportunities to address the climate–trade dilemma in China," is available here.
"The amazing increase in Chinese manufacturing over the past 15 years has driven the world economy to new heights and supplied consumers in developed countries with tremendous quantities of lower-cost goods," said co-author Steven J. Davis, UCI assistant professor of Earth system science. "But all of this has come at substantial cost to the environment."
Noise pollution harms wildlife, degrades habitats
October 5, 2015 09:11 AM - Shreya Dasgupta, MONGABAY.COM
Traffic noise is just another inconvenience for many of us. But for wildlife, noise from honking, and zooming vehicles can often be an insidious threat: it can degrade habitats without leaving any physical evidence of change, warns a recent study published in the Proceedings of the National Academy of Sciences.
Road noise — even in moderate levels — pushes migrating birds away from their stopover habitats, researchers from Boise State University in Idaho found. Those that stay back become weak.
“I was initially surprised that even moderate road noise — comparable to a suburban setting — would have such a wide-ranging impact on migrating birds,” William Laurance, a professor at James Cook University in Cairns, Australia, who was not involved in the study, told Mongabay. “On reflection, however, I guess such migrators have to be hyper-vigilent about noise, as they’re constantly moving to new areas where unseen predators could be lurking.”
Could Mealworms Help Solve our Styrofoam Waste Problem?
October 2, 2015 03:16 PM - Kevin Mathews, Care2
Plastic waste is out of control in this country, and Styrofoam is one of the worst offenders. Americans toss out 25 billion Styrofoam cups each year. Over two million tons of the stuff ends up in landfills, where it does not biodegrade. Scientists think they may have found a solution for our Styrofoam problem, though: feed it to the worms!
The Volkswagen emissions cheating scandal and it's potential impact on VW owners
October 1, 2015 06:53 AM - YUKI NOGUCHI, NPR
Out of the 250 million cars and trucks on U.S. roads, the impending recall at Volkswagen will involve just a half-million of them. But VW's emissions cheating scandal is receiving outsize attention because many of the company's customers feel duped. Now those customers are weighing what it will take to make them feel whole again.
David Chien of Williston, Vt., was looking for a bigger, fuel-efficient car that could power its way through Northeastern snow. He says the 2013 Jetta SportWagen he bought "seemed to check all the boxes."
New water-tracing technology helps protect groundwater
September 30, 2015 04:18 PM - University of New South Wales via EurekAlert!
UNSW Australia researchers have used new water-tracing technology in the Sydney Basin for the first time to determine how groundwater moves in the different layers of rock below the surface.
The study provides a baseline against which any future impacts on groundwater from mining operations, groundwater abstraction or climate change can be assessed.
