• Mystery Behind Slithering Rocks of Death Valley Revealed

    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. >> Read the Full Article
  • Yawn Contagion in Wolves

    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. >> Read the Full Article
  • Catching Fog

    "This is one of the best beers that I have ever tried," says Andrés Barrera. My friend is enjoying a craft beer called Atrapaniebla — Spanish for fog catcher — an ale made with water condensed from mountain fog on two fog catchers. The microbrewery that produces it, located in Peña Blanca (some 360 kilometres north of Santiago, the Chilean capital), is one of the first Chilean enterprises to make use of fog-catching technology; others use it to water tomato and aloe vera crops. "Water from fog catchers has less nitrite and nitrate than the drinking water in the north of Chile, which is good for beer," says Miguel Ángel Carcuro, 29-year-old co-owner of the microbrewery that makes Atrapaniebla. Of course, while beer is nice, water is essential and fog catchers can be a great way to provide this sometimes scarce commodity. Carcuro's interest in this technology stems from teenage travels with his father, who showed him a hill above the bay of Chungungo, where there were the remains of fog catchers that had until recently provided water for 100 families. >> Read the Full Article
  • How Geckos can walk on the ceiling

    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. >> Read the Full Article
  • 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. >> Read the Full Article
  • How did sea life end up living in outer space?

    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. >> Read the Full Article
  • Drought Causes Western US to Rise

    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. >> Read the Full Article
  • Fracking's Chemical Cocktails

    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. >> Read the Full Article
  • NASA reports unknown source of banned ozone-destroying compound

    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. >> Read the Full Article
  • Turning Jellyfish into Sustainable Medical Products

    In a United Nations report released in May, scientists worldwide were called upon to join the war on jellyfish. According to the report, jellyfish have overwhelmed the marine ecosystem as a result of the overfishing of more competitive species, consuming fish eggs and larvae of weaker specimens and creating what the report called a "vicious cycle." So how can this cycle be stopped? >> Read the Full Article
