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.

A Fukushima-Sized Problem
August 27, 2014 11:45 AM - Karl Grossman, The Ecologist

A newly-exposed report by Diablo Canyon's lead nuclear inspector shows that the twin reactors are unsafe, writes Karl Grossman. An earthquake on nearby geological faults could trigger a Fukushima-scale accident causing 10,000 early fatalities. The owner's response? Apply to extend the site's operation for another 20 years. As aftershocks of the 6.0 Napa earthquake that occurred Sunday in California continued, the Associated Press revealed a secret government report pointing to major earthquake vulnerabilities at the Diablo Canyon nuclear plants which are a little more than 200 miles away and sitting amid a webwork of earthquake faults.

Dams vs. Rivers
August 27, 2014 08:40 AM - Editor, The Ecologist

A new 'State of the World's Rivers' database shows how the world's rivers have been impoverished by dams and their ecosystems devastated - and provides a valuable resource to help save river basins that remain in good health. International Rivers has launched 'The State of the World's Rivers', an interactive online database that illustrates the role that dams have played in impoverishing the health of the world's river basins.

Network of rapid EV chargers planned for London
August 27, 2014 07:17 AM - ClickGreen staff, ClickGreen

The Energy Saving Trust and Transport for London (TfL) have announced a new initiative to identify potential sites for rapid electric vehicle charging points across the capital. The scheme organisers say one of the aims of their programme is to help businesses expand their use of cleaner vans and light lorries throughout Greater London.

Uncontrolled Trash Burning Significantly Worsens Air Pollution
August 26, 2014 04:20 PM - UCAR AtmosNews

Unregulated trash burning around the globe is pumping far more pollution into the atmosphere than shown by official records. A new study led by the National Center for Atmospheric Research estimates that more than 40 percent of the world's garbage is burned in such fires, emitting gases and particles that can substantially affect human health and climate change.

Verizon On Track to Be No. 1 Solar-Power Producer Among U.S. Communications Companies
August 26, 2014 08:53 AM - CleanTechies Guest Author, Clean Techies

Verizon announced today that it will invest nearly $40 million to expand the on-site green energy program that it launched in 2013. This year, Verizon will install 10.2 megawatts of new solar power systems at eight Verizon network facilities in five states — California, Maryland, Massachusetts, New Jersey and New York. This investment nearly doubles the amount of renewable power generated by solar energy systems installed at six Verizon facilities last year.

The Magnitude 6.0 NAPA earthquake
August 26, 2014 07:05 AM - Roger Greenway, ENN

A strong earthquake hit the Napa valley yesterday. The US Geological Survey has provided a detailed summary of the quake and the possibilities of both strong aftershocks and the remote potential of an aftershock stronger than the quake (Magnitiude 6.0) The earthquake occurred within a 70-km-wide (44 miles) set of major faults of the San Andreas Fault system that forms the boundary between the Pacific and North American tectonic plates. The persistent northwestward movement of the Pacific plate relative to North America primarily causes right-lateral slip across the major faults, but also causes deformation between the major faults. The ongoing complex deformation field is revealed by modern geodetic surveys and earthquake patterns as well as the regional geologic structure.

How Cutting Emissions Pays Off
August 25, 2014 04:28 PM - Audrey Resutek, MIT News

Lower rates of asthma and other health problems are frequently cited as benefits of policies aimed at cutting carbon emissions from sources like power plants and vehicles, because these policies also lead to reductions in other harmful types of air pollution. But just how large are the health benefits of cleaner air in comparison to the costs of reducing carbon emissions?

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.
