Control of the lion fish
January 24, 2014 09:32 AM - Robin Blackstone, ENN
A recent Oregon State University study shows that controlling the invasive lionfish in the western Atlantic Ocean is likely to allow for recovery of native fish. The lionfish is estimated to have wiped out 95% of native fish in some Atlantic locations. This Atlantic invasion is believed to have begun in the 1980s and now covers an area larger than the United States.
Should governments give serious consideration to electric car only city centres? Over the last 12 months the subject of electric car only city centres has been discussed on numerous occasions although so far no government has been brave enough to push through any formal regulations. The authorities continue to encourage the use of electric vehicles within city centres, assisting with creating a network of recharging stations, but perhaps they could be doing more? Only a few days ago we wrote about an expert in the field of electric vehicles who is suggesting that financial incentives should be focused towards commercial operations such as taxis and vehicle fleets. The idea is that taxis and vehicle fleets cover the most mileage per annum compared to your traditional motorist and therefore electric vehicles will be more visible under this particular strategy.
Human response to climate
January 22, 2014 10:22 AM - B. Rose Huber, Woodrow Wilson School of Public and International Affairs, Princeton University
Throughout history, humans have responded to climate. Take, for example, the Mayans, who, throughout the eighth and 10th centuries, were forced to move away from their major ceremonial centers after a series of multi-year droughts, bringing about agricultural expansion in Mesoamerica, and a clearing of forests. Much later, in the late 20th century, frequent droughts caused the people of Burkina Faso in West Africa to migrate from the dry north to the wetter south where they have transformed forests to croplands and cut the nation's area of natural vegetation in half.
How Labeling Helps us Choose Efficient Light Bulbs
January 22, 2014 08:37 AM - Allison Winter, ENN
When shopping for "green", "energy efficient", or "organic" products, consumers often have to decide if the price is worth it as these products are generally more expensive at the checkout line. Here starts the dilemma: how much would you pay for a healthier, nontoxic product or is an upfront cost worth energy efficient savings in the long run? When it comes to purchasing light bulbs, according to a new study conducted by Leeds University Business School and Carnegie Mellon University, consumers are more willing to buy energy efficient brands when the energy costs are clearly labeled.
Great Lakes evaporation hypothesis up in the air
January 21, 2014 03:24 PM - Robin Blackstone, ENN
The recent Arctic blast gripping the nation will likely contribute to a rise in Great Lakes water levels in 2014, new research from the University of Michigan and Michigan State University shows. Research conducted by the two schools through the Great Lakes Integrated Sciences and Assessments Center (GLISA) shows the correlation between periods of high and low evaporation and its effect on ice cover. Years with high ice cover were usually followed by cooler summer water temperatures and lower evaporation rates, but these same high-ice winters were preceded by high evaporation rates during the autumn and early winter indicating a two-way connection between ice cover and evaporation. While ice cover reduces evaporation from what would otherwise be exposed lake surface water, it also reduces lake temperature generating ice cover.
Natural sugar batteries could be running world's gadgets within 3 years

Scientists have developed a high-energy battery that runs on sugar and could be powering the world's gadgets within just three years. Researchers believe the new cheaper, refillable and biodegradable battery could soon replace conventional batteries.
Is plant virus linked to honeybee Colony Collapse Disorder (CCD)?
January 21, 2014 08:27 AM - Jim Sliwa, American Society for Microbiology
A viral pathogen that typically infects plants has been found in honeybees and could help explain their decline. Researchers working in the U.S. and Beijing, China report their findings in mBio, the online open-access journal of the American Society for Microbiology. The routine screening of bees for frequent and rare viruses "resulted in the serendipitous detection of Tobacco Ringspot Virus, or TRSV, and prompted an investigation into whether this plant-infecting virus could also cause systemic infection in the bees," says Yan Ping Chen from the U.S. Department of Agriculture's Agricultural Research Service (ARS) laboratory in Beltsville, Maryland, an author on the study.
Should activities in public space be limited? The UK approach.
January 21, 2014 07:02 AM - Josie Appleton, The Ecologist
Laws handing sweeping new powers to police and private security to restrict access to Britain's public space will extinguish the diversity of civic life, writes Josie Appleton. Time for us to rediscover and defend our freedoms! Councils and the police will have an almost free hand to determine the use of all public spaces from civic squares to rural footpaths. The idea of public space, as it developed in the modern period, was space for the free use and enjoyment of the citizenry. The temper and character of public space should be determined not by any private or public authority, but by the ways in which people choose to use it. A bill currently passing through the UK Parliament will mean the death-knell of this principle.
Biofuels Patents Surge, Small Players Drive Solar Lead
January 20, 2014 01:33 PM - Eric Lane, Clean Techies
The Clean Energy Patent Growth Index (CEPGI) recently released its Third Quarter 2013 Results. Researched and published by the Heslin Rothenberg law firm, CEPGI is a quarterly report on clean energy patents granted in the United States.
Beaver, Dam it!
January 20, 2014 09:32 AM - Enn Staff, The Ecologist
As climate change brings more rain, there will be more catastrophic flooding; flooding of crops, homes and businesses, particularly in urban areas where there is simply no place for the water to go. One British writer has identified the beaver as the would-be hero to restore hydrological normalcy. Louise Ramsey writes about the beaver in Britain where reintroductions of the rodent have shown the vital role they once had in reducing flooding and how they could take up that mantle once more.
