Developed strong as Spiderman Web of Silk

U.S. researchers have created silkworms that are genetically modified to spin silk stronger.
In a report in the journal PNAS, the scientists of University of Wyoming, said that their ultimate goal is to produce silk from silkworms who had a class toughness of spider silk. From the comparison of weight, spider silk is heavier than steel.
In comic books, Spiderman web of the spider produces strong. In fact it can be used nets to trap criminals and swinging in the city skyscrapers.
The researchers indeed have tried to produce silk for a few decades back. But it was impossible to make spider farms for commercial production. Because the animals kind of spider silk does not produce enough. Plus a tendency among each other that eat each other.
While the caterpillars somehow manageable for breeding and produce a lot of silk, though easily breakable.
Researchers have tried for several years to get the best combination of the two animals. Namely, strong silk in industrial quantities, with mentransplansi gene from the spider into the caterpillar. But the results, which are genetically modified, showing worms did not produce spider silk is quite a lot.
GM caterpillars produced by a team led by Professor Don Jarvis of the University of Wyoming. He saw the production of a combined worm and spider silk in large quantities. The researchers say it's just not as strong as spider silk.
Commenting on the work Don Jarvis, Christopher Holland of Oxford University said the development was memperlihatikan a stage in the future that will be able to produce a strong silk commercially.
"In principal, this paper shows that they are capable of taking a component of spider silk and make a silkworm, spin into fibers such as those generated spider," said Holland.
These researchers hope to produce super-strong silk in a number of industries. In addition, spiders GM also will be used instead of plastic.
Not only that, Professor Guy Poppy from the University of Southampton said they will not pose a threat to the environment and he believes the benefits will be greater and minimal risk.
"It's hard to see how silkworms to produce silk like a spider's snare, and will have an advantage in nature," he said.
