      A major field trial of GM wheat that is designed to repel aphids (small insects) has found the crop is no better protected against the pests than conventional wheat. The results come from two years of trials that compared aphid attacks on standard wheat plants with those suffered by a GM version modified to release a natural aphid repellent.

      Scientists created the GM wheat strain in the hope that it would deter aphids, which devour the crops and can leave them with infections. They modified the wheat to produce a natural pheromone which aphids release when under attack from predators. The “aphid alarm” makes the bugs flee to safety. Aphids are not the only organisms that release the odour though. More than 400 plants have evolved to secrete the same substance, called E-betafarnesene, or EBF, including peppermint. The chemical doubles up as an attractant for some insects that kill aphids, such as parasitic wasps.

      Prior to the field trial, lab tests at Rothamsted found that the pheromone worked as a highly-effective aphid repellent. The work bolstered researchers’ hopes that the trial would demonstrate the crop’s resilience against aphids in the wild. An aphid-resistant wheat crop could have huge benefits for farmers and the environment because the plants would no longer need to be sprayed with insecticides.

      “The disappointing thing is that when we tested it in the field, we didn’t find any significant reduction in aphid settlement in the test plots,” said Toby Bruce, who worked on the trial. Details of the trial are published in the journal Scientific Reports.

                                    Genetically modified foods

      Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism. Currently available GM foods stem mostly from plants, but in the future foods derived from GM microorganisms or GM animals are likely to be introduced on the market. Most existing genetically modified crops have been developed to improve yield, through the introduction of resistance to plant diseases or of increased tolerance of herbicides.

      In the future, genetic modification could be aimed at altering the nutrient content of food, reducing its allergenic potential, or improving the efficiency of food production systems. All GM foods should be assessed before being allowed on the market. FAO/WHO Codex guidelines exist for risk analysis of GM food.

Sustainable flight

   TAM was the first airline in South America to carry out an experimental flight using biofuel on November 22, 2010. Produced from the oil of 100% domestic nettlespurge, known in Portuguese as pinhão-manso, it reduces carbon emissions by between 65% and 80% compared with petroleum-derived kerosene, according to research. Besides, the plant does not threatens the food chain, as it is not edible for humans nor animals. “Compared with other biofuels, the fuel from this plant is very promising for the Brazilian scenario,” says Paulus Figueiredo, TAM’s fuel manager. The next step in the project is to implement a farming unit, in reduced scale, at TAM’s Technological Center in São Carlos (SP), exclusively to conduct studies and make better cultivation techniques viable. “The objective is to carry out studies concerning technical and economic viability to build a biofuel Brazilian platform based on nettlespurge,” explains TAM’s CEO, Líbano Barroso. The experimental flight was a joint effort between TAM, Airbus, CFM International (joint venture between U.S.’s GE and the French Safran Group) and Air BP. The trip was authorized by Brazil’s National Civil Aviation Agency (ANAC) and by the European Aviation Safety Agency (EASA).

                                    Why use biofuels for aviation?
The aviation industry has seen huge growth since its beginning. Today, more than two billion people enjoy the social and economical benefits of flight each year. The ability to fly conveniently and efficiently between nations has been a catalyst for the global economy and has shrunk cultural barriers like no other transport sector. But this progress comes at a cost.
In 2008, the commercial aviation industry produced 677 million tones of carbon dioxide (CO2 ). This is around 2% of the total man-made CO2 emissions of more than 34 billion tones. While this amount is smaller compared with other industry sectors, such as power generation and ground transport, these industries have viable alternative energy sources currently available. For example, the power generation industry can look to wind, hydro, nuclear and solar technologies to make electricity without producing much CO2 . Cars and buses can run on hybrid, flexible fuel engines or electricity.
-powered trains can replace
locomotives.
The aviation industry has identified the development of biofuels as one of the major ways it can reduce its greenhouse gas emissions. Biofuels provide aviation with the capability to partially, and perhaps one day fully, replace carbon-intensive petroleum fuels. They will, over time, enable the industry to reduce its carbon footprint significantly.
