This virus steals DNA from black widow spider venom to attack its prey

A type of virus that only infects bacteria has stolen the DNA of black widow spiders to attack its prey. And just not any DNA, but the genes that code for spider venom. This is the first time we’ve seen a virus take genes from such a complex organism.
