Spinning spider webs without spiders

he silk fibers in spider webs have for decades inspired scientists to create imitations in the laboratory. But the imitations rarely approach the standard: Spider silk is stronger than many high-performance synthetic fibers and has greater elasticity. Now, a team has transferred spider genes into mammalian cells and generated fibers that have some of the properties of natural silk. The fibers are biodegradable and could be used as sutures for surgeries, for example.

I read somewhere that they geneticaly engineered a goat/spider.

instead of milk, the goat gave silk like a spiders. stronger than steel, but still silk like in nature
