LOGAN — Ready for an amazing spider-related sequel? Well, you’ll have to wait until July to see Spider-Man in theaters, but two Utah State University faculty members already have welcomed two sets of cloned spider goat twins.
Spider goats, as scientists informally call them, are goats that have been modified as embryos to introduce a spider gene that allows the female goats to produce a milk containing spider silk. The strong silk substance, not in web form, is then isolated and purified before use.
