It might look like a poorly
drawn picture of an alien, but this is actually
one of the most advanced
types of skin ever made - that can even stop bullets.
Researchers genetically engineered goats to produce milk which is packed with the same protein
as silk spiders.
Once this is milked out it can be spun out and weaved into a material that is ten times stronger than steel.
can then be blended with human skin to make what the scientists hope will be tough enough to stop even a bullet.
Dutch researcher Jalila Essaidi said the "spidersilk" project
was called "2.6g 329m/s" after the weight and the velocity
of a .22 calibre long rifle bullet.
She said the goal was to replace
the keratin in our skin with the spider's silk.
The first stage involves growing a layer of real skin around a sample
of the bulletproof skin, which takes about five weeks.
A video posted by the researchers on YouTube shows a bullet
then being fired into the mixture
of the two.
Essaidi said that the project
was making science fiction
a reality, even if the tests results were not yet perfect.
She said that silk has a long history of using battle in combat
and that Genghis Khan once issued all his horsemen with silk vests as an arrow hitting silk does not break, meaning you can tease it out.
"Imagine a spidersilk vest, capable
of catching bullets, the modern day equivalent
of Genghis Khan's arrows," she said.
Essaidi said："Now, let's take this one step further, imagine replacing keratin, the proteinresponsible
for the toughness of the human skin, with this spidersilk protein. This is possible by adding the silk producing genes of a spider
to the genes of a human: creating a bulletproof human."
Bullet proof vests have been around for decades but skin that can stop them has only been the preserve
of science fiction.
