Bt
pronald | June 13, 2012Over the past 16 years, vast plantings of transgenic crops producing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) have helped to control several major insect pests and reduce the need for insecticide sprays. Today, a report in Nature shows that planting of BT crops is also associated with an increase of ladybirds, lacewings and spiders, which are natural enemies of certain pests that harm the crop.
On the basis of data collected from 1990 to 2010 at 36 sites in six provinces of northern China, the authors show a marked increase in abundance in these three arthropods…
pronald | March 9, 2010Check out this great post by Mary M on biofortifed. In it she reviews a new research paper that describes how the use of Bt could potentially save the lives of millions.
You can download a video about the researchers and their work here.
From Mary's post: "For some people, a great deal of the conflama around genetically-engineered (GE) crops has to do with the presence of a pesticide in the plant material--mainly the Bacillus thuringiensis or Bt protein--rather than coating the surface of the plant as organic Bt sprays or chemical-style pesticides would. No matter how many times I explain…

Eggplants are found in many colors: green, white, purple, yellow, even striped. They are shaped like cucumbers or apples. They are eaten in Italy as melanzane alla parmigiana, in France as ratatouille, and in the Middle East as baba ghanoush.
My husband Raoul usually grows Imperial Black Beauty, Rosa Bianca, and the hybrids Beatrice and Nadia. We cook them shortly after harvest:
Spicy Eggplant
2 Eggplants, diced into 1/2" cubes
3 tbsp Olive oil
1 Clove of garlic, smashed and chopped
1/2 tsp Chile flakes
1. Sauté smashed and chopped clove of garlic in the olive oil.
2. Add the chile flakes…

A large study weighs up the existing evidence on the impact of GM crops on local insect life, providing some much-needed scientific rigour to the GM debate.
In Europe, the 'GM debate' about the merits and dangers of genetically-modified (GM) crops is a particularly heated one. There is a sense of unease about the power of modern genetic technology, and a gut feeling that scientists are 'playing God'. These discontents are stoked by the anti-GM camp, who describe GM crops with laden and fear-mongering bits of unspeak like 'Frankenstein foods' and 'unnatural'.
In a debate so fuelled by…
