Examples of metaphor in popular science writing:

""[Francisco] Mojica made a bold and untested hypothesis – that this planidrome-space system is a bacterial weapon against viruses."

"…this system evolved in an arms race with viruses. Viruses attack bacteria as well as humans, We fend most of them off with our immune system. This bacterial mechanism …uses a molecular guide and scalpel: the palindromes help form the guides that bring a molecular scalpel to cut the viral DNA to render it harmless."
