To Help Bees, Skip Herbicides and Pesticides, Keep Lawns Naturally Diverse
October 7, 2016 04:23 PM - University of Massachusetts Amherst
Declining populations of pollinators is a major concern to ecologists because bees, butterflies and other insects play a critical role in supporting healthy ecosystems. Now a new study from urban ecologists at the University of Massachusetts Amherst suggests that when urban and suburban lawns are left untreated with herbicides, they provide a diversity of “spontaneous” flowers such as dandelions and clover that offer nectar and pollen to bees and other pollinators.
UC Researcher Develops Clean Water-Treatment Option to Target Sporadic Outbreaks
October 5, 2016 10:26 AM - John Bach
A University of Cincinnati scientist has engineered an environmentally friendly technology to zap outbreak-causing viruses and bacteria from public drinking water.
Environmental and biomedical engineer David Wendell, an associate professor in UC’s College of Engineering and Applied Science, developed a protein-based photocatalyst that uses light to generate hydrogen peroxide to eliminate E. coli, Listeria, and potentially protozoa like giardia and cryptosporidium.
The Psychology Behind Climate Change Denial
October 5, 2016 06:53 AM - Uppsala University
Climate change is a serious threat to humans, animals, and the earth’s ecosystems. Nevertheless, effective climate action has been delayed, partly because some still deny that there is a problem. In a new thesis in psychology, Kirsti Jylhä at Uppsala University has studied the psychology behind climate change denial. The results show that individuals who accept hierarchical power structures tend to a larger extent deny the problem.
In the scientific community there is a strong consensus that humans have significantly affected the climate and that we are facing serious challenges. But there is a lot of misinformation about climate change in circulation, which to a large part is created and distributed by organised campaigns with the aim of postponing measures that could combat climate change. And there are people who are more prone than others to trust this misinformation.
Previous research has consistently shown that it is more common among politically conservative individuals to deny climate change. In her thesis, Kirsti Jylhä has investigated this further and in more detail. Her studies included ideological and personality variables which correlate with political ideology, and tested if those variables also correlate with climate change denial.
New Technology Helps Pinpoint Sources of Water Contamination

Berkeley Lab develops better method of environmental monitoring using the PhyloChip, finds surprising results in Russian River watershed
When the local water management agency closes your favorite beach due to unhealthy water quality, how reliable are the tests they base their decisions on? As it turns out, those tests, as well as the standards behind them, have not been updated in decades. Now scientists from Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a highly accurate, DNA-based method to detect and distinguish sources of microbial contamination in water.
First evidence of deep-sea animals ingesting microplastics
October 3, 2016 07:11 AM - University of Oxford
Following the news that the UK government is to ban plastic microbeads by the end of 2017, a team of scientists led by the University of Oxford has discovered the first evidence of microplastics being ingested by deep-sea animals.
Researchers working on the Royal Research Ship (RRS) James Cook at two sites in the mid-Atlantic and south-west Indian Ocean found plastic microfibres inside creatures including hermit crabs, squat lobsters and sea cucumbers at depths of between 300m and 1800m.
Potentially harmful chemicals widespread in household dust

Household dust exposes people to a wide range of toxic chemicals from everyday products, according to a study led by researchers at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University. The multi-institutional team conducted a first-of-a-kind meta-analysis, compiling data from dust samples collected throughout the United States to identify the top ten toxic chemicals commonly found in dust. They found that DEHP, a chemical belonging to a hazardous class called phthalates, was number one on that list. In addition, the researchers found that phthalates overall were found at the highest levels in dust followed by phenols and flame retardant chemicals.
Wetlands and agriculture, not fossil fuels could be causing a global rise in methane
September 30, 2016 07:07 AM - Royal Holloway University of London
Research published today in the American Geophysical Union’s journal Global Biogeochemical Cyclesshows that recent rises in levels of methane in our atmosphere is being driven by biological sources, such as swamp gas, cow burps, or rice fields, rather than fossil fuel emissions.
92% of the world's population exposed to unsafe levels of air pollution
September 29, 2016 07:18 AM - World Health Organization
A new WHO air quality model confirms that 92% of the world's population lives in places where air quality levels exceed WHO limits. Some 3 million deaths a year are linked to exposure to outdoor air pollution. Indoor air pollution can be just as deadly. In 2012, an estimated 6.5 million deaths (11.6% of all global deaths) were associated with indoor and outdoor air pollution together.
It May Not Cost You More To Drive Home In A Climate-Friendly Car
September 27, 2016 02:34 PM - NPR
It has been a common belief that low-emissions vehicles, like hybrids and electric cars, are more expensive than other choices. But a new study finds that when operating and maintenance costs are included in a vehicle's price, cleaner cars may actually be a better bet.
Could California's gridlock generate electricity for the grid?
September 27, 2016 02:05 PM - Yale Environment 360
California is testing whether its heavy traffic can produce not just emissions and air pollution, but electricity. The state’s Energy Commission says it will spend $2 million to examine the potential of using piezoelectric crystals embedded under asphalt as a way to send the energy created by moving cars to the grid.
