Study Suggests More Research before Fracking Continues
August 29, 2014 07:22 AM - ClickGreen Staff, ClickGreen
An independent report on fracking has recommended a temporary moratorium on the controversial process and says that communities should give permission before it can proceed. The interdisciplinary expert panel set up by the Nova Scotia regional government says the science of fracking is relatively unknown and therefore its introduction should be delayed in the Province until the science and its environmental effects are better understood.
"Global Roadmap" Created to Balance Development with Environmental Protection
August 28, 2014 11:49 AM - Morgan Erickson-Davis, MONGABAY.COM
Roads make it possible to bring goods to market, to get to the office, to log a forest, to hunt its wildlife. Without roads, human society as we know it could not exist. However, to build roads, trees must be cleared and swamps drained, shrinking valuable wildlife habitat and fragmenting populations in the process. A new study, published today in Nature, unveils an innovative map that defines which areas of the world would best be used to build roads — and which should be left alone. Scientists estimate more than 25 million kilometers of new roads will be built worldwide by 2050, representing a 60 percent increase over 2010 numbers. Many of these are slated for environmentally valuable places with high numbers of unique species and pristine forest, such as the Amazon Basin.
Mystery Behind Slithering Rocks of Death Valley Revealed
August 28, 2014 09:38 AM - Allison Winter, ENN
In California's Death Valley, a geological phenomenon exists. Sailing stones, or moving rocks can be observed on the valley floor inscribing long trails on the ground without human or animal intervention. For over 60 years of observations, no one has been able to uncover the mystery of what is actually pushing these stones across the sand. That is, until now.
Yawn Contagion in Wolves
August 27, 2014 04:15 PM - Editor, ENN
A yawn is defined as a reflex act of opening one's mouth and inhaling deeply. We yawn most often when we are tired or when we're bored. But we also always yawn when we see someone else doing it. Why? People say we can't help it - it's contagious! But what really triggers this involuntary tendency? According to studies, yawning when others do is a sign of empathy and a form of social bonding. And believe it or not, we're not the only species to exhibit these contagious behaviors. A new study published today in the journal PLOS ONE shows that wolves may also be susceptible to yawn contagion.
How Geckos can walk on the ceiling
August 25, 2014 11:26 AM - Roger Greenway, ENN
Ever wonder how lizards like Geckos can walk up walls and even across the ceiling? Is it sticky feet, anti-gravity, or what? Researchers at Oregon State University have developed a model that explains how geckos, as well as spiders and some insects, can run up and down walls, cling to ceilings, and seemingly defy gravity with such effortless grace. This ability, outlined today in the Journal of Applied Physics, is a remarkable mechanism in the toes of geckos that uses tiny, branched hairs called "seta" that can instantly turn their stickiness on and off, and even "unstick" their feet without using any energy.
Electricity from silk cocoons?

Researchers in India say they have developed a prototype of an energy-harvesting device from the cocoons of a domesticated species of silk moth. They hope to put the technology to practical use while also tackling waste materials from the silk processing industry.
How did sea life end up living in outer space?
August 25, 2014 07:50 AM - Care2 Causes Editor Viola Knowles, Care2
Russian astronauts, or cosmonauts, have discovered living organisms clinging to the exterior of their International Space Station. The microscopic creatures were discovered during a space walk to clean the surface of the vessel, and they’ve reportedly been identified as a type of sea plankton. But scientists have no idea how they got there.
Drought Causes Western US to Rise
August 22, 2014 02:00 PM - Editor, ENN
Severe drought affecting the western United States in recent years is not only influencing water restrictions for residence and creating problems for crops and wildlife, but it's changing the landscape by causing land to rise up in elevation.
Fracking's Chemical Cocktails
August 22, 2014 09:15 AM - Tim Radford, The Ecologist
Fracking is once again in trouble. Scientists have found that what gets pumped into hydrocarbon-rich rock as part of the hydraulic fracture technique to release gas and oil trapped in underground reservoirs may not be entirely healthy. Environmental engineer William Stringfellow and colleagues at Lawrence Berkeley National Laboratory and the University of the Pacific told the American Chemical Society meeting in San Francisco that they scoured databases and reports to compile a list of the chemicals commonly used in fracking.
NASA reports unknown source of banned ozone-destroying compound
August 21, 2014 07:33 AM - ClickGreen Staff, ClickGreen
NASA research has revealed the Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source decades after the compound was banned worldwide. Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to the ozone hole over Antarctica. Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012.
