Can Technology End Overfishing?
April 2, 2014 07:57 AM - Alexis Petru, Triple Pundit
Back in 2002, Thomas Kraft, managing director of Norpac Fisheries Export, came up with the idea to electronically track each fish the company captures and sells. Soon after Norpac's electronic monitoring system was up and running two years later, Kraft realized that the technology was not only an effective management tool, but it could also help the company trace fish through the supply chain and guarantee its products were not caught using illegal, unreported and unregulated (IUU) fishing practices.
NASA study finds Arctic melt is now 15 days longer than 30 years ago
April 1, 2014 10:48 AM - ClickGreen Staff, ClickGreen
The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap’s thickness, according to a new study by National Snow and Ice Data Center (NSIDC) and NASA researchers.
'Extreme levels' of Roundup are the norm in GMO soya
April 1, 2014 09:05 AM - Thomas Bøhn and Marek Cuhra, Ecologist
To accommodate high levels of Roundup residues in GM soya, limits were raised 200-fold - with no scientific justification and ignoring growing evidence of toxicity. What Monsanto calls 'extreme levels' are now the norm - but only in GM crops.
Seaweed forests could help power tropical islands
April 1, 2014 06:45 AM - Jan Piotrowski, SciDevNet
Harvesting seaweed 'forests' and feeding them into large underwater digesters could one day meet the world's energy needs, with nine per cent of the ocean floor being enough to replace fossil fuels entirely, according to an ambitious idea. Even a more immediate and realistic use of seaweed — a major untapped resource — would greatly increase the self-sufficiency and sustainability of small island states, but limited investment is preventing the roll-out of relevant technologies, marine biofuel experts have said.
Meeting climate targets may require reducing diet of meat and dairy

Greenhouse gas emissions from food production may threaten the UN climate target of limiting global warming to 2 degrees Celsius, according to research at Chalmers University of Technology in Sweden.
Climate-hit fisheries 'can still meet demand in 2050'
March 31, 2014 09:04 AM - Zoraida Portillo, SciDevNet
Fish catches will need to increase by only 3.4 per cent to meet global dietary demand in 2050, according to a study predicting how climate change will affect marine ecosystems. The authors warn that achieving this will require the wider implementation of sustainable harvesting, such as technological developments to reduce dependence on wild stock for farmed fish feed, and more-effective distribution of wild fish products from regions with a surplus to those with a deficit.
Desalination is Now a Billion Dollar Industry, Report Shows
March 31, 2014 08:07 AM - Phil Covington, Triple Pundit
Despite some early March rain in California, and a few storm systems moving in this week, the late season moisture will sadly fall far short of that which is needed to pull the state out of its four-year drought.
Revealed For The First Time: The Surprising Biodiversity Of Algae 'Reefs'
March 30, 2014 06:53 PM - Morgan Erickson-Davis, MONGABAY.COM
Most people are familiar with coral reefs, but very few have ever heard of their algal equivalent — rhodolith beds. Yet, these structures provide crucial habitat for many marine species. In the first study of its kind, published in mongabay.com’s Tropical Conservation Science, researchers unveil just how important these beds are for bottom-dwelling organisms, and the species that depend on them. Superficially similar to coral, rhodoliths are made up of various kinds of photosynthetic red algae (Corallinaceae and Rhodophyta species) that form hard structures as they grow. They drift along with the currents, gradually accumulating calcium carbonate in their cells, until they get too heavy for water to move them.
Ground breaking battery technology promises to extend EV range
March 30, 2014 09:09 AM - BOB SHETH, Electric Forum
Over the last few years much of the talk with regards to the electric vehicle sector has focused upon battery restrictions with many people calling for greater investment in the sector. There was a general consensus emerging that lithium ion batteries had perhaps been pushed to their technological limit and we may need to strip back the battery sector and go back to square one. However, researchers at the University of Limerick have announced a ground breaking breakthrough which could effectively double the life of an electric vehicle battery. This new development incorporates the latest nanotechnology which is something that will impact every area of everyday life. It is a technology which has been around for a few years but is still in its infancy with regards to its potential to change areas such as battery storage capacity.
Being Married DOES have health benefits!
March 29, 2014 08:09 AM - Editor ENN from EurekAlert
Analysis of surveys of more than 3.5 million American men and women, administered at some 20,000 health centers across the country — believed to be the largest analysis of its kind ever performed — found that married people, regardless of age, sex, or even cardiovascular risk factors, had significantly less chances of having any kind of cardiovascular disease than those who were single, divorced or widowed. Among the study's key findings, to be presented March 29 in Washington, DC, at the annual scientific sessions of the American College of Cardiology: Being married carried a 5 percent lower risk of having any cardiovascular disease than being single Widowed and divorced people were, respectively, 3 percent and 5 percent more likely to suffer from any kind of cardiovascular disease, including peripheral artery disease, cerebrovascular disease, abdominal aortic aneurysm, and coronary artery disease
