Scientists genetically modify mosquitoes in a high-security laboratory – and they hope that insects will help eliminate some diseases transmitted from mosquitoes that continue to hurt the community around the world
It is known as a genetic cause: where mosquitoes, modified to not transmit a particular virus, are used to replace the existing insect population for several generations, with modified genes transmitted to all their offspring. The idea is controversial because it changes with the fundamental principles of nature, but now it is considered by the World Health Organization (WHO). This test has entered a new phase, according to NPR, with a large-scale release of genetically modified brain in a room in Terni (Italy).
"It really will be a breakthrough experiment," says entomologist Ruth Muller. Laboratory, said Rob Stein at NPR. "This is a historical moment. It's very interesting."
Using the CRISPR method for editing "molecular scissors," the gene known as "duplex" in error has been modified. The gene transforms female mosquitoes by removing their biting abilities and making them fruitless. Artificial lights are used to simulate the sunrise and sunset.
The idea is to see if mosquitoes from the CRISPR-editable genetic code can destroy unmodified insects inside the cells. This follows from previous studies of conceptual concepts that we have seen before.
In the end, these mosquitoes could be released in areas affected by malaria, which led to the fact that the local population lost their brains and saved human lives. The disease is responsible for more than 400,000 deaths annually ̵
Reducing these numbers sounds like a great idea, why is this dispute? Well, many scholars are calling for caution when it comes to changing the genetic code at this fundamental level – we just do not know what influence these genetically modified mosquitoes will have on the surrounding world
. to minimize any chance that specially designed mosquitoes can escape. The tests were also specially located in Italy, where this type of mosquito – Anopheles gambiae – could not survive on the street in the natural climate.
to know where it will end, "said Nnimmo Bassey, director of the Earth's Healthy Mother Earth Foundation in Nigeria. "We need to stop this exactly where it is. They are trying to use Africa as a great laboratory for testing risky technologies."
Some experts believe that the addition of genetically modified mosquitoes to natural ecosystems can damage other plants and animals that depend on them. There are many unknowns.
The team that stands behind new experiments is opposed to criticism, saying that they are working slowly and methodically – and that the potential side effects outweigh the benefits of malaria eradication.
At the moment, scientists are targeting only one type of mosquito from hundreds, and several years of research and consultation is planned to release genetically modified brain.
"There will be problems with any technology," one of the research groups, "Tony Nolan of the Imperial College in London, UK, said NPR."
"But I do not think you should throw out technology without do everything possible to understand what its potential should be transformative for medicine. it would be transforming. "
