Beijing growing explosively, impacting weather and climate
June 26, 2015 05:12 AM - JPL NASA
A new study by scientists using data from NASA's QuikScat satellite has demonstrated a novel technique to quantify urban growth based on observed changes in physical infrastructure. The researchers used the technique to study the rapid urban growth in Beijing, China, finding that its physical area quadrupled between 2000 and 2009.
A team led by Mark Jacobson of Stanford University, Palo Alto, California, and Son Nghiem of NASA's Jet Propulsion Laboratory, Pasadena, California, used data from QuikScat to measure the extent of infrastructure changes, such as new buildings and roads, in China's capital. They then quantified how urban growth has changed Beijing's wind patterns and pollution, using a computer model of climate and air quality developed by Jacobson.
Pope Francis challenges us all on Climate Change and improving the life of the poor
June 18, 2015 07:52 AM - Steffen Böhm, University of Essex, The Ecologist
The Encyclical due to be published today by Pope Francis represents a profound religious and philosophical challenge to the mainstream narratives of our times, writes Steffen Böhm, and a major confrontation with the great corporate, economic and political powers, as it spells out the potential of a new world order rooted in love, compassion, and care for the natural world.
Improving the lives of slum dwellers and addressing climate change is, for Pope Francis, one and the same thing. Both require tackling the structural, root causes of inequality, injustice, poverty and environmental degradation.
Dogs don't like people who are not nice to their owners!
June 14, 2015 06:08 AM - AFP via Discovery News
Dogs do not like people who are mean to their owners, Japanese researchers said Friday, and will refuse food offered by people who have snubbed their master.
The findings reveal that canines have the capacity to co-operate socially -- a characteristic found in a relatively small number of species, including humans and some other primates.
Switzerland Promotes Neighborhood Exchange Boxes
June 1, 2015 08:49 AM - Tex Dworkin, Care2
If someone were to set up a telephone booth sized box on your street filled with unwanted items — such as books, toys and small knick knacks, perhaps — and then topped it off with a “Free” sign, what do you think would happen? If Switzerland is any indication, passersby turned salvagers and recyclers would appear out of nowhere, sifting their way through other people’s unwanted discards, thinking up ways to put their newfound discoveries to good (re)use. Some would even add their own unwanted items to the box. Neighborhood exchange boxes have helped Geneva, Switzerland reuse 32 tons of goods thus far thanks to a program called BOÎTES D’ÉCHANGE ENTRE VOISINS–A box for exchange between neighbors. But can it work in other cities?
Lifecycle of Today's Cell Phone
April 7, 2015 08:57 AM - ClickGreen Staff, ClickGreen
It is estimated that in 2014 over two billion mobile phones were sold worldwide. Of these, over one billion were estimated to be smartphones. It is also estimated that a massive 87% of the world’s population now use mobile phones. These are staggering figures, but how many of us have ever stopped to think of where our precious mobile phones came from and what happens to them once we discard them for a newer model?
Each year millions of mobile phones are produced in the world and an equal number are disposed of. In the vast majority of cases these discarded phones work perfectly well. However, like all technological products these days, phones have a built-in technological obsolescence (we demand the latest model or the latest upgrade) as well as a built in aesthetic obsolescence (we demand the latest style or design).
In spite of their extremely small size and simplicity of look, mobile phones are immensely complex pieces of technology with many, many components. If we stop to think about it for a moment all of these products need sourcing: the raw materials needed to produce them need extracting from the ground, these need to manufactured into working parts which are then assembled into the final phone.
Antioxidant Effects differ by Leaf Color
March 27, 2015 01:47 PM - University of the Basque Country
Lettuce, one of the indispensable vegetables in the Mediterranean diet, is a food that greatly benefits health, mainly because it is rich in antioxidants. But not all lettuce varieties have the same antioxidant effect. According to a study led by the researcher Usue Pérez-López of the Department of Plant Biology and Ecology of the UPV/EHU's Faculty of Science and Technology, the colour of the leaves of these vegetables determines the speed at which their compounds act. So lettuces with green leaves have antioxidants that react more slowly while red-leaf ones have a faster effect. The results of this study have been set out in a paper "Phenolic Composition and Related Antioxidant Properties in Differently Coloured Lettuces: A Study by Electron Paramagnetic Resonance (EPR) Kinetics" recently published by the ‘Journal of Agricultural and Food Chemistry'.
What inspires people to support conservation?
March 10, 2015 09:11 AM - Cornell University via EurekAlert!
What inspires people to support conservation? As concerns grow about the sustainability of our modern society, this question becomes more important. A new study by researchers at Cornell University provides one simple answer: bird watching and hunting.
This survey of conservation activity among rural landowners in Upstate New York considered a range of possible predictors such as gender, age, education, political ideology, and beliefs about the environment. All other factors being equal, bird watchers are about five times as likely, and hunters about four times as likely, as non-recreationists to engage in wildlife and habitat conservation. Both bird watchers and hunters were more likely than non-recreationists to enhance land for wildlife, donate to conservation organizations, and advocate for wildlife-all actions that significantly impact conservation success.

Salting Roads takes a Toll on the Environment
January 14, 2015 10:49 AM - Kevin Mathews, Care2
The United States has a salt problem, and it extends well beyond the excessive sodium we consume in our diets. In the winter months, municipalities rely on dumping salt on the roads to minimize the effects of ice. Altogether, the U.S. uses ten times the amount of salt on roadways than it does in the processed foods we consume. While the salt may help to keep drivers safe, it does come at a cost:
1. It Increases Our Own Salt Consumption
You can throw salt down on roads, but you can’t force it to stay there. In due time, salt makes its ways into nearby waterways where it lingers. As a result, a lot of the water we wind up drinking has higher levels of salt than it would otherwise. Vox cites a study that finds 84% of city-adjacent streams have higher levels of chloride thanks specifically to these road-salting techniques. Apparently, during the months following salted roads, 29% of these streams have more salt than the federal “safety limits” for drinking water allow.
