Chilean Sea Bass?
May 26, 2013 06:12 AM - KYLE HENCE/ecoRI News contributor
Who knew? Chilean sea bass is not from Chile, nor is it a bass. Since 1996, fishing vessels from a dozen nations have traversed the world’s most remote sea to catch the Antarctic toothfish. The fishery lands 3,000 tons annually, selling much of it as "Chilean sea bass," deceiving customers of high-end restaurants and supermarket chains around the world and threatening "the most pristine marine ecosystem on Earth," according to the filmmakers behind "The Last Ocean," which was recently screened at the Casino Theater.
Jaffna aquifer depleting from overuse
May 24, 2013 08:54 AM - Dilrukshi Handunnetti, SciDevNet
The single limestone aquifer, which is the main source of freshwater in Sri Lanka's northern Jaffna peninsula, is gradually depleting through overuse, researchers say. "The area suffers from severe groundwater imbalance which might reach crisis proportions in the future," Shanti de Silva, one of two scientists who carried out the research for the agricultural department of the University of Jaffna, told SciDev.Net.
Free Range Milk?
May 24, 2013 06:17 AM - Lorna Howarth, The Ecologist
Free-Range Dairy is a new initiative that could reverse the trend towards industrialised mega-farms. The Ecologist office is set in an Area of Outstanding Natural Beauty within a United Nations Biosphere Reserve. Hartland peninsular is dotted with steep, wooded valleys where bluebells, early purple orchids and woodpeckers abound.The hills afford breathtaking views across the Bristol channel to Lundy Island, itself a nature reserve with a no-fish zone that is having a beneficial effect on marine ecology, and looking south-west down to Cornwall, on a clear day, one can see to Boscastle and Bodmin moor beyond. But something is missing from this bucolic scene - one notices it first whilst walking the country lanes on a warm spring evening. There is no rhythmic munching of grass on the other side of the hedge; no bovine belching or contented sighing as the cows enjoy the sun on their backs after a long winter in the cattle yard. For here in Hartland, as elsewhere in the country, the trend is towards carbon-intensive, 'industrialised' farming where huge herds of 1,000 cows or more are kept indoors all year long, with only a concrete yard for exercise.
New Anti-Staph Drugs
May 23, 2013 04:08 PM - Andy Soos, ENN
Bugs and infections are growing ever stronger and more resistant to the antibiotics and the like. A team of Wisconsin scientists has synthesized a potent new class of compounds capable of curbing the bacteria that cause staph infections. They describe these new agents as effectively interfering with the quorum sensing behavior of Staphylococcus aureus, a bacterium at the root of a host of human infections ranging from acne to life-threatening conditions such as pneumonia, toxic shock syndrome and sepsis.
What is Causing the Big Shrimp Die-Off in Asian Shrimp Farms?
May 23, 2013 05:50 AM - Mike Ives, SciDevNet
A cause of a mysterious disease devastating shrimp farms across Asia since 2009 has been tracked back to a strain of a bacteria native to coastlines around the world. The shrimp early mortality syndrome has perplexed experts for years, in a region where roughly one million people depend on shrimp farming for survival. So far countries officially reporting the disease — also referred to as acute hepatopancreatic necrosis syndrome — include China, Malaysia, Thailand and Vietnam, but potentially it could affect shrimp farming further afield in Asia, as well as parts of Latin America and Africa.
Eat those white vegetables?
May 20, 2013 03:27 PM - Allison Winter, ENN
We've always been told that eating colorful foods has many health benefits. And no, I'm not talking about artificially colored candies or chips, but instead fresh fruits and vegetables. Many produce rich in color contains nutrient packed pigments and antioxidants that provide energy and other benefits to our bodies. Consequently, it is recommended that we have three to five servings of fruits and vegetables every day. But what about white foods? Some nutritionists urge us to stay away from white bread breads, rice and pastas, but what about white produce? There are potatoes, garlic, onions, mushrooms, cauliflower, onions, turnips and kohlrabi just to name a few. Are these white fruits and vegetables just as nutritious?
Fishing the Gulf of Maine: Tradition at a Crossroads
May 20, 2013 11:41 AM - Michael Sanders, The Ecologist
Lobster fishing remains big business off the coast of Maine but even with new regulations and new gadgets can it ever be sustainable? Michael Sanders investigates the real costs of the crustacean on your plate... When most of us go down to the coast, whether to walk or swim or fish or sail, we take for granted what we see before us. We see the lobster boats and the colorful buoys marking the strings of traps, the bobbing green and red cans marking safe passage, the gulls and other seabirds. In the larger working harbors like Portland and Stonington and Port Clyde, there might be draggers tied up, unloading fish they've caught far out in the Gulf of Maine and on Georges Bank. What we don't realize is that this seemingly unchanging marine world is in fact always changing in ways both large and small. What we think of as "the coast of Maine" - those 3,000 vaunted miles of rocky shoreline punctuated by seaside villages and docks and lobster pounds and fishing fleets - was largely built on the backs of the fishermen and lobstermen who are there, however picturesque or authentic to the eye, for a single purpose: to harvest the sea in order to feed us.
Vitamin C and Gout
May 20, 2013 09:26 AM - Andy Soos, ENN
Vitamin C or L-ascorbic acid, or simply ascorbate (the anion of ascorbic acid), is an essential nutrient for humans and certain other animal species. Vitamin C has been advocated for many other therapeutic uses. Vitamin C functions as an antioxidant and is necessary for the treatment and prevention of scurvy, though in nearly all cases dietary intake is adequate to prevent deficiency and supplementation is not necessary. Though vitamin C has been promoted as useful in the treatment of a variety of conditions, most of these uses are poorly supported by the evidence and sometimes contraindicated. Despite previous studies touting its benefit in moderating gout risk, new research reveals that vitamin C does not reduce uric acid (urate) levels to a clinically significant degree in patients with established gout. Vitamin C supplementation, alone or in combination with allopurinol, appears to have a weak effect on lowering uric acid levels in gout patients according to the results published in the American College of Rheumatology (ACR) journal, Arthritis & Rheumatism.
Drought and Desertification - Global Response
May 19, 2013 09:11 AM - ANDREW BURGER, Global Warming is Real
Land degradation — more specifically drought and desertification — have become increasingly pressing problems for a growing number of countries around the world, threatening efforts to alleviate poverty, improve basic health and sanitation and address socioeconomic inequality, as well as spur agricultural and sustainable economic development. The only multilateral, international agreement linking development and environment to sustainable land management (SLM), high-level representatives from 195 nations will be gathering in Windhoek, Namibia from September 16-27 for the 11th bi-annual Conference of Parties (COP) to review implementation of the United Nations Convention to Combat Desertification (UNCCD). Meeting for the first time in southern Africa, UNCCD delegates will review implementation of the convention to date and plan for the ensuing two years of programs and actions.
Keeping Produce Fresh Longer
May 15, 2013 01:49 PM - Allison Winter, ENN
Billions of dollars of fruits, vegetables, and flowers are thrown away each year as produce ripens too quickly and starts to rot in different markets before public buyers even buy them. Even though you might expect these products to start rotting to their death after they are first harvested, researchers explain that fruits, vegetables and flowers are still alive after they are picked. In fact, once these products are picked, they produce and release into the air ethylene gas, a crucial component for the ripening and blooming process.
