Hot and Cold Freezers
September 10, 2014 09:25 AM - Bill DiBenedetto, Triple Pundit
The freezers being tested in Central Park operate free of electricity — vendors can even charge their own mobile devices by plugging them into outlets attached to the freezer units. It seems fitting that Unilever, the world's largest producer of ice cream, is rolling out the world's first solar freezers in Central Park to keep those Popsicles, Good Humor or Magnum-brand bars cold while at the same time putting no strain on the environment.
Hazardous waste-eating bacteria discovered
September 10, 2014 09:07 AM - The University of Manchester
Although bacteria with waste-eating properties have been discovered in relatively pristine soils before, new research shows for the first time that microbes that can survive in the very harsh conditions expected in radioactive waste disposal sites have also been found. The ultimate aim of this research conducted by the University of Manchester is to improve our understanding of the safe disposal of radioactive waste underground by studying the unusual diet of these hazardous waste eating microbes.
Should the Pacific walrus be considered a threatened species?
September 8, 2014 03:52 PM - USGS Newsroom
A recent U.S. Geological Survey estimates that the Pacific walrus population nearly halved between 1981 and 1999, the last year for which demographic data are available. The study notes that the decline was most severe in the mid-1980s, and then moderated in the 1990s. Currently, the USGS is working to obtain more recent population data of the Pacific walrus. This information will be vital because the U.S. Fish & Wildlife Service is expected to determine whether the Pacific walrus should be listed as threatened under the Endangered Species Act in 2017.
How Pollutant Risk is Affected by Different Insect Stages
September 5, 2014 11:34 AM - Editor, ENN
The food chain is a hierarchical series of organisms that are interrelated in their feeding habits. The chain starts when the smallest being like an insect is fed upon a larger prey species, which in turn feeds an even larger species. So if a species among the lower ranks of the chain has accumulated toxins such as pesticides or other organic chemicals, there is potential for these toxic substances to affect the species that prey upon them. This is the subject of new research conducted by the US Geological survey that found when fish feed on insects and when other wildlife species feed on fish, harmful contaminants are transferred up the line.
UN licenses kick off search for underwater minerals
September 5, 2014 08:07 AM - Rodrigo de Oliveira Andrade, SciDevNet
The International Seabed Authority (ISA) has begun issuing exploration licenses for mining the yet untouched floor of international waters raising concerns about potential environmental impacts. The licenses, issued on 21 July, grant prospecting rights for underwater minerals to private and state-owned companies from Brazil, Cook Islands, Germany, India, Russia, Singapore and the United Kingdom.
New software helps us choose products, ingredients based on sustainability
September 4, 2014 07:09 AM - Alexis Petru, Triple Pundit
How can a manufacturer reformulate a cleaning product to contain fewer harmful chemicals, and how can a retailer stock its shelves with more eco-friendly merchandise? UL (Underwriters Laboratories), a product safety testing and certification company, thinks it may have a solution: a set of data tools that helps businesses search and choose ingredients and products based on their environmental and social responsibility profiles.
New way to remove greenhouse gases from the atmosphere
September 4, 2014 07:01 AM - Institute for Integrated Cell-Material Sciences, Kyoto University, via EurekAlert
Researchers in Japan have engineered a membrane with advanced features capable of removing harmful greenhouse gases from the atmosphere. Their findings, published in the British journal Nature Communications, may one day contribute to lower greenhouse gas emissions and cleaner skies. Greenhouse gases, originating from industrial processes and the burning of fossil fuels, blanket the earth and are the culprits behind current global warming woes. The most abundant among them is carbon dioxide, which made up 84% of the United State's greenhouse gases in 2012, and can linger in Earth's atmosphere for up to thousands of years.
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.
