Scientific Advances Can Make it Easier to Recycle Plastics

ENN Pollution - Fri, 11/17/2017 - 23:25
Most of the 150 million tons of plastics produced around the world every year end up in landfills, the oceans and elsewhere. Less than 9 percent of plastics are recycled in the United States, rising to about 30 percent in Europe.

Plant Respiration Could Become a Bigger Feedback on Climate Than Expected

ENN Climate - Fri, 11/17/2017 - 22:41
New research, led by the Centre for Ecology & Hydrology, suggests that plant respiration is a larger source of carbon emissions than previously thought, and warns that, as the world warms, this may reduce the ability of Earth’s land surface to absorb emissions due to fossil fuel burning.

Seagrass is a Key Fishing Ground Globally

ENN Agriculture - Fri, 11/17/2017 - 22:28
New research demonstrates that seagrass meadows are important fishing grounds all around the globe. The work highlights that there is an urgent need to start appreciating and understanding this role to be able to build more sustainable fisheries. A study led by Dr Lina Mtwana Nordlund at Stockholm University, published in the scientific journal Fish & Fisheries, examines the global extent to which these underwater meadows support fishing activity.

What Climate-Conscious Cities Can Learn From Each Other

ENN Climate - Fri, 11/17/2017 - 22:24
In many ways, Essen is the envy of cities trying to move past their industrial days. Once the steel and coal center of Germany, Essen’s economic success in the early 20th century was evident in the dust blanketing the city and sulfur filling the air with the constant stench of rotten eggs. By one resident’s account, coal miners permanently wore black smudges across their faces, earning them the nickname waschbar, or “raccoons.”

The Importance of Biodiversity in Forests Could Increase Due to Climate Change

ENN Climate - Fri, 11/17/2017 - 22:03
Leipzig. Forests fulfil numerous important functions, and do so particularly well if they are rich in different species of trees. This is the result of a new study. In addition, forest managers do not have to decide on the provision of solely one service – such as wood production or nature conservation – as a second study demonstrates: several services provided by forest ecosystems can be improved at the same time. Both studies were led by scientists from Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv), and published in the prestigious journal Ecology Letters.

Asthma Attacks Reduced in Tree-Lined Urban Neighbourhoods

ENN Health - Fri, 11/17/2017 - 21:44
People living in polluted urban areas are far less likely to be admitted to hospital with asthma when there are lots of trees in their neighbourhood, a study by the University of Exeter’s medical school has found.

Widespread chemical contaminants stunt growth of amphibians

ENN Pollution - Fri, 11/17/2017 - 20:54
A series of synthetic chemicals widely used in household products, food packaging and clothing have a significant effect on the development of frogs, even at low doses, according to a Purdue University study.Per/polyfluoroalkyl substances (PFASs) are man-made chemicals used to make products stain resistant, waterproof and nonstick, and are present in foams used to fight fires. A U.S. Centers for Disease Control and Prevention (CDC) study from 2007 showed that some PFASs were present in 98 percent of blood samples collected from American adults and children for the National Health and Nutrition Examination Survey. According to the CDC, scientific studies on the impact of PFASs on human health are inconclusive.

Virginia Tech works to protect Africa's crops against invasive pests

ENN Agriculture - Fri, 11/17/2017 - 18:41
As invasive and indigenous insect pests continue to wreak havoc on crops across Africa, a Virginia Tech-led project is intensifying its work to coordinate a response that looks beyond geographic and financial barriers.Stopping crop losses requires working across borders, said Muni Muniappan, director of the Virginia Tech-led Feed the Future Innovation Lab for Integrated Pest Management. “Fighting these pests in just a few of these countries is futile, because it will continue to thrive in the countries where we are not working,” he said.

Modern Air is a Little Too clean: The Rise of Air Pollution Denial

ENN Pollution - Thu, 11/16/2017 - 23:59
Despite report after report linking air pollution to deterioration of the lungs, heart and brain, Professor Robert Phalen believes the air is “too clean” for children.After all, everybody needs a bit of immune-system-boosting dirt in their lungs.“Modern air is a little too clean for optimum health,” he told the American Association for the Advancement of Science (AAAS), one of the world’s largest scientific societies, in 2012.

Groundwater Depletion Could be Significant Source of Atmospheric Carbon Dioxide

ENN Agriculture - Thu, 11/16/2017 - 23:33
Humans may be adding large amounts of carbon dioxide to the atmosphere by using groundwater faster than it is replenished, according to new research. This process, known as groundwater depletion, releases a significant amount of carbon dioxide into the atmosphere that has until now been overlooked by scientists in calculating carbon sources, according to the new study.

When Vegetables Are Closer in Price to Chips, People Eat Healthier, Drexel Study Finds

Genomic Study Explores Evolution of Gentle 'Killer Bees' in Puerto Rico

ENN Agriculture - Thu, 11/16/2017 - 23:21
A genomic study of Puerto Rico's Africanized honey bees – which are more docile than other so-called “killer bees” – reveals that they retain most of the genetic traits of their African honey bee ancestors, but that a few regions of their DNA have become more like those of European honey bees. According to the researchers, these changes likely contributed to the bees' rapid evolution toward gentleness in Puerto Rico, a change that occurred within 30 years.

New Research Shows: Organic Farming Can Make an Important Contribution to World Nutrition

ENN Agriculture - Thu, 11/16/2017 - 22:33
A global conversion to organic farming can contribute to a profoundly sustainable food system, provided that it is combined with further measures, specifically with a one-third reduction of animal-based products in the human diet, less concentrated feed and less food waste. At the same time, this type of food system has extremely positive ecological effects, i.e. considerable reduction of fertilizers and pesticides, and reduced greenhouse gas emissions – and does not lead to increased land use, despite lower agricultural yields. These are the findings of a new study, which included the Vienna-based Department of Social Ecology among its contributors. Results have recently been published in “Nature Communications”.

'The Brazilian Zika outbreak could end soon'

ENN Health - Thu, 11/16/2017 - 22:23
In 2016, news about the Zika virus in Brazil made the headlines in Europe for the first time. With approximately 65 million people affected, it is one of the largest epidemics in the last few years. The Olympics additionally fuelled fears that the virus could spread globally. When the first cases of newborns with microcephaly, i.e. malformations of the brain, were observed in connection to Zika, it became apparent that further research was called for. The DZIF responded to this global challenge and, under the leadership of Jan Felix Drexler, Charité – Universitätsklinikum Berlin, initiated a German alliance project with Brazilian scientists, which investigates the pathogenesis and epidemiology of Zika.
