Montreal households the greenest in Canada: UBC study
July 27, 2016 11:51 AM - University of British Columbia via EurekAlert!
Montreal homes are the most sustainable in the country, and Edmonton's the least, according to a new University of British Columbia study that compares average household greenhouse gas emissions in major cities across Canada.
Using census data over a 12-year span, researchers ranked cities on how much carbon dioxide the average Canadian family (two to three people) with an annual income of $81,000 in each city produced in a year from the combined use of electricity, gasoline and natural gas.
The average Montreal household produces five tonnes of GHG per family per year, while the average Edmonton household emits 20 tonnes per family per year.
Low Zika risk for travelers to Olympics in Brazil, study finds
July 26, 2016 07:23 AM - Michael Greenwood, Yale News
The Zika virus poses a negligible health threat to the international community during the summer Olympic Games that begin next month in Rio de Janeiro, Brazil, according to researchers at Yale School of Public Health (YSPH).
In a worst-case scenario, an estimated 3 to 37 of the thousands of athletes, spectators, media, and vendors traveling to Rio for the Olympics will bring the Zika virus back to their home countries, the researchers concluded.
Global Economy Has Reduced Its Energy Intensity by One-Third Since 1990
July 25, 2016 01:41 PM -
The global economy is becoming less energy intensive, using fewer fossil fuels to power productivity and economic growth, according to new data from the U.S. Department of Energy. Global energy intensity — a measure of energy consumption per unit of gross domestic product (GDP) — has decreased nearly one-third since 1990, the agency said. The U.S., for example, burned 5,900 British thermal units per dollar of GDP in 2015, compared to 6,600 BTUs in 2010.
Can cinnamon turn you into a better learner?
July 25, 2016 07:16 AM - VETERANS AFFAIRS RESEARCH COMMUNICATIONS via EurekAlert!
If Dr. Kalipada Pahan's research pans out, the standard advice for failing students might one day be: Study harder and eat your cinnamon!
Pahan a researcher at Rush University and the Jesse Brown Veterans Affairs Medical Center in Chicago, has found that cinnamon turns poor learners into good ones--among mice, that is. He hopes the same will hold true for people.
Why Americans waste so much food
July 22, 2016 06:51 AM - Martha Filipic, Ohio State University
Even though American consumers throw away about 80 billion pounds of food a year, only about half are aware that food waste is a problem. Even more, researchers have identified that most people perceive benefits to throwing food away, some of which have limited basis in fact.
A study published today in PLOS ONE is just the second peer-reviewed large-scale consumer survey about food waste and is the first in the U.S. to identify patterns regarding how Americans form attitudes on food waste.
Ship engine emissions adversely affect macrophages
July 19, 2016 11:00 AM - Helmholtz Zentrum München - German Research Center for Environmental Health via EurekAlert!
In cooperation with colleagues of the University of Rostock, the University of Luxembourg, the Max Delbrueck Center for Molecular Medicine, the Karlsruhe Institute of Technology and the University of Eastern Finland, the Munich Scientists have now published the results in the journal PLOS ONE. In 2015 they already showed that exposure to particle emissions from heavy fuel oil (HFO) and diesel fuel (DF) adversely affects human lung cells and is responsible for strong biological responses of the cells ("How Ship Emissions Adversely Affect Lung Cells"). For example, inflammatory processes are triggered that may influence the development of interstitial lung diseases. Now the team led by Professor Ralf Zimmermann has found in further studies that macrophages are also influenced by the exhaust gases. These are much more sensitive than lung epithelial cells and therefore react more strongly to exposure. Zimmermann is speaker of the international consortium Helmholtz Virtual Institute of Complex Molecular Systems in Environmental Health (HICE), head of the cooperation group Comprehensive Molecular Analytics (CMA) at Helmholtz Zentrum Muenchen and head of the Department of Analytical Chemistry at the University of Rostock.
India: The Burning City
July 14, 2016 09:23 AM - Al Jazeera
Underground fires have been burning for more than a century beneath India's largest coalfield, but in recent decades open-cast mining has brought the flames to the surface with devastating consequences for the local population.
As communities are destroyed and thousands suffer from toxic fumes, what lies behind this human and environmental disaster?
Filmmakers Gautam Singh and Dom Rotheroe went to find out.
The devastating impact of coal mining
After the US and China, India is currently the world's third-largest energy consumer; a position that is set to consolidate in coming years as economic development, urbanisation, improved electricity access, and an expanding manufacturing base all add to demand.
Right now much of those energy needs - up to two thirds of all electricity generated - are being met by domestically produced coal, of which India has abundant reserves.
Fruit and veg give you the feel-good factor
July 11, 2016 10:17 AM - University of Warwick via EurekAlert!
University of Warwick research indicates that eating more fruit and vegetables can substantially increase people's later happiness levels.
Published in the prestigious American Journal of Public Health, the study is one of the first major scientific attempts to explore psychological well-being beyond the traditional finding that fruit and vegetables can reduce risk of cancer and heart attacks.
Happiness benefits were detected for each extra daily portion of fruit and vegetables up to 8 portions per day.
Researchers assess heatwave risks associated with climate change
July 8, 2016 06:35 AM - IOP Publishing via EurekAlert!
Combining climate and mortality data, researchers have estimated that 315 deaths in Greater London and 735 deaths in Central Paris can be strongly linked to the 2003 heatwave that set record-breaking temperatures across Europe. Taking their analysis a step further, they determine that 64 (± 3) deaths from the London dataset and 506 (± 51) deaths from the Paris dataset are attributable to anthropogenic climate change, which increased the risk of heat related mortality by 20% and 70%, respectively, in the two cities. The team, led by scientists from the University of Oxford and Public Health England, has reported its latest findings in the journal Environmental Research Letters.
The Antarctic Ozone Hole May Be Closing
July 7, 2016 07:21 AM - s.e. smith
There’s good news from Antarctica, where researchers with tools like ozonesondes — pictured above — have been following the infamous ozone hole as it waxes and wanes over the seasons. The ozone hole has shrunk by 1.5 million square miles – around 4 million square kilometers — and this “healing” trend appears to be continuing.
A major ecological catastrophe has been averted, and we can cite human intervention as the reason. When the globe swept into action with 1987′s Montreal Protocol, which banned a number of substances known to contribute to ozone depletion, it apparently worked.
When scientists first began to observe a hole in the ozone layer over Antarctica, it was a cause for grave concern. Though ozone levels actually fluctuate throughout the year, they perform an important function by blocking the sun’s harmful UV radiation.
