From Spider-Man to Spider-Goat - PAU inglés 2006 Andalucía

>Exámenes selectividad inglés resueltos Andalucía


Along came a Spider-Goat comic bookIt all began when Peter Parker was attending a high-school demonstration of radiation technology. A spider crept into the beam of radiation and bit Peter's hand. This gave him superhuman spider-like abilities. In the original comic book, Peter's new talents inspired him to invent his trusty webslingers, small jets attached to his wrists that fire a special polymer that hardens on contact with air.
Anyone who has ever walked into a spider's web knows that the silk is extremely solid. Despite its delicate appearance it is stronger than steel. Unfortunately, it's very difficult to farm spiders for their silk because they tend to eat each other. So, scientists have tried a variety of different methods to produce the silk without arachnid help. One of the more successful ones relies on stealing the spider's silk gene and putting it into something more friendly – like a goat. In an unlikely coupling, genetic engineers have now bred goats that have spider silk genes inside them. By doing this, they can harvest the silk proteins from the goat's milk. One goat can produce about 7g of silk per day.
Called “biosteel,” the silk is weightless, yet tougher than Kevlar (an artificial but incredibly light and strong fiber), and nearly as elastic as nylon. It could be used in medical supplies, space equipment and bullet-proof vests. So there's a new superhero in town, it's … Spider-Goat!
