“Sustainable Aquaculture” – challenges for a growing industry
On 27 February at Aquaculture 2007, the Trienniel Meeting of the World Aquaculture Society, National Shellfisheris Society and American Fisheries Society – Fish Culture Section, the Plenary Lecture was given by Dr Jason Clay of the World Wildlife Fund. The theme was how the WWF is acting to promote sustainable food production, focusing on aquaculture.…
USDA Support For GM Rice With Human Genes
The US Department of Agriculture is allowing Ventria Bioscience to go ahead with field-scale cultivation of rice containing human genes that can be used to help fight diarrhoea. The company has introduced human genes into rice that encode lactoferrin and lysozyme, two proteins found naturally in breast milk. Ventria recently reported a Journal of Pediatric…
How Safe Is Making Drugs in GM Plants?
Transgenic plants offer a route to making some pharmaceuticals cheaply and effectively, but concerns have been raised that they could pose risks too. Jeff Wolt and his colleagues at Iowa State University argue that the consequences of intended and unintended use both must be considered and managed to understand the risks of such plant-made pharmaceutical…
Bluetongue in Northern Europe
The recent bluetongue epidemic in northern Europe began in the summer (August) of 2006 and cases have been detected up until January 2007. The outbreak has been caused by serotype 8 of the virus and of the 2124, 695 cases were reported from Belgium, 7 from France, 952 from Germany, 460 from the Netherlands, and…
Drink coffee, feed the world?
As I sat bleary-eyed in the staff restaurant at CABI drinking a morning cup of coffee today, was I simply having a shot of caffeine to keep me going after an early start. Or, as it was Fairtrade coffee I was drinking, was I making a real contribution to improved livelihoods of small farmers in…
Frog fungus
At the risk of developing a ‘save the animals’ theme, and despite saying last week that moving species around may not be a good idea, I’m now advocating the adoption of frogs by zoos, aquaria and botanic gardens. This is, however, to promote an ex situ conservation programme to slow amphibian extinction in the crisis…
Rebuilding a Brazilian rainforest
The Brazilian Atlantic rainforest once spanned in excess of a million square kilometres. However, nowadays it barely covers 7% of that. The deforestation that has occurred has left farmers and wildlife with failing springs, receding groundwater and destroyed habitats. An ambitious project in Brazil’s most crowded state, São Paulo, aims to bring the rainforest and…
Is circumcision the answer to HIV?
Two randomised controlled trials from Kenya and Uganda reported in the Lancet this week have shown that circumcising men can halve the HIV infection rate. This is great news for controlling HIV, confirming what has been suspected for years. The operation is cheap and simple to carry out and just has to be done once.…
Thai rubber industry plans to bounce back from El Niño
El Niño, the ocean-atmosphere phenomenon that does so much to shape the course of the world’s weather, is now giving officials in Thailand particular cause for concern. The Meteorological Department in Bangkok has announced that the cool, dry season has lasted an unusually long time, beyond its normal November to January range. The worry is…
Dolly: ten years after
The cloning of “Dolly” from adult sheep tissue was widely hailed as a breakthrough 10 years ago this week, when it was published in Nature. David Wells of AgResearch, New Zealand, says “it is still remarkable that NT [nuclear transfer] using differentiated donor cells can produce physiologically normal cloned animals.” However, as he points out…
