The Abundance of Invasive Species
October 25, 2013 04:05 PM - Robin Blackstone, ENN
Recognizing that invasive species are major catalysts for environmental change, researchers from the University of Wisconsin—Madison are relooking at how we account for invasive species populations. Instead of researching the behaviors and habits of the invasive species, researchers Gretchen Hansen and Jake Vander Zanden are considering abundance distributions of invasive species. They hypothesize that measuring abundance in an area is a more helpful determinate for defining the most optimal methods of prevention, containment, control and eradication.
Breakthrough in CO2 conversion to useful forms of carbon
October 25, 2013 07:22 AM - Roger Greenway, ENN
CO2 is an important air pollution emission contributing to climate change. Researchers around the globe are looking at ways to remove CO2 from flue gasses and to store it (sequestering) or to in someway use it. By tuning gold nanoparticles to just the right size, researchers from Brown University have developed a catalyst that selectively converts carbon dioxide (CO2) to carbon monoxide (CO), an active carbon molecule that can be used to make alternative fuels and commodity chemicals. "Our study shows potential of carefully designed gold nanoparticles to recycle CO2 into useful forms of carbon," said Shouheng Sun, professor of chemistry and one of the study’s senior authors. "The work we've done here is preliminary, but we think there's great potential for this technology to be scaled up for commercial applications."
Introduction to Persistent, Bioaccumulative, Toxic (PBT) Compounds in the Environment
October 24, 2013 05:03 PM - Robin Blackstone, ENN
Global chemical contamination is a worldwide concern affecting every being on earth. Chemical exposure, whether it is through air, water, plants, soil or our modern living environment is unavoidable. But certain chemicals and compounds having Persistent, Bioaccumulative, Toxic (PBT) characteristics are more dangerous to our environment than others because of their inability to break down easily, are easily transferred throughout all forms of environmental media, and posing risks to human health and the ecosystem due to their toxicity at low concentrations.
Ecology: Life's Connections
October 24, 2013 04:41 PM - Glen Barry, Ecologist
Ultimately, all humanity and all life have is the biosphere, the thin layer of life just above and below Earth’s surface, composed of ancient, miraculously evolved natural ecosystems. The natural Earth is a marvel - a complex coupling of species within ecosystems, whereby life begets life. Ecology is far more than the study of life and its environment. The word is used here as a synonym for ecosystems - the vibrant connections that emerge between species across scales, which cumulatively make life on Earth possible.
Dead battery troubles will soon be a thing of the past
October 24, 2013 04:26 PM - Debra Goldberg, ENN
With technology almost always at our fingertips, it’s hard to avoid constantly being on our smart phone, camera, or tablet. It distracts us from our boredom, connects us quickly to friends, helps navigate us to local restaurants, and points out the nearest gas stations when we’re running low on fuel.
Wind power could generate 18% of global power by 2050
October 24, 2013 08:45 AM - ClickGreen Staff, ClickGreen
Wind power could generate up to 18% of the world's electricity by 2050, compared with 2.6% today, according to new IEA research. The Technology Roadmap: Wind Energy — 2013 Edition finds that nearly 300 gigawatts of current wind power worldwide must increase eight- to ten-fold to achieve the roadmap's vision, with the more than USD 78 billion in investment in 2012 progressively reaching USD 150 billion per year.
Air Pollution and Cancer Spikes linked in Alberta
October 23, 2013 11:48 AM - Editor, ENN
Alberta is Canada's industry epicenter and home to more than 40 companies that produce industrial emissions. Recent studies conducted by the University of California and the University of Michigan have indicated higher levels of contaminants which can potentially be linked to spikes in the incidences of cancer in the region.
Green Building is Now the Law in Dallas

Dallas has now accepted the first building permit applications under its green building ordinance. Dallas is one of the first major cities in the nation to implement comprehensive mandatory green building standards for both all new residential and commercial construction. By Resolution 08-1070 adopted unanimously on April 9, 2008 Phase 1 of the law was effective in 2009 and Phase 2 (originally to be effective October 1, 2011) was fully implemented October 1, 2013.
Great Progress in Fukushima Daiichi Nuclear Accident Remediation Efforts
October 23, 2013 08:27 AM - Editor, ENN
United Nation experts are encouraging the Japanese government to better communicate contamination goals with the public but are otherwise very positive about the progress that has been made in the Fukushima Daiichi nuclear accident remediation efforts in Japan. The experts are from the International Atomic Energy Agency (IAEA) a U.N. task force who oversees and reviews remediation efforts. They have been conducting ongoing reviews of the situation since the 2011 earthquake.
How life in ocean sediments responds to climate change
October 23, 2013 06:08 AM - ScienceDaily
Traces of past microbial life in sediments off the coast of Peru document how the microbial ecosystem under the seafloor has responded to climate change over hundreds of thousands of years. For more than a decade scientists at the Max Planck Institute for Marine Microbiology and their colleagues at MARUM and the University of Aarhus have investigated microbial life from this habitat. This "Deep Biosphere," reaching several hundred metres below the seafloor, is exclusively inhabited by microbes and is generally considered as stable. Nevertheless, only little is known about how this system developed over millennia and how this microbial life influences the cycling of carbon in the oceans. In a new study appearing in the Proceedings of the National Academy of Sciences (PNAS) Dr. Sergio Contreras, a palaeoceanographer, and his Bremen colleagues use a careful examination of drill-cores from the continental shelf of Peru to actually show how surprisingly dynamic this deeply buried ecosystem can be.
