OT: that headline is a really interesting sentence. There are two people, the biologist and the computer scientist, and the word discover is singular. Note that if it were one person who was both a biologist and computer scientist, we'd say "biologist and computer scientist discovers", with the plural form of discover.

I'm a native English speaker, and have no trouble understand the sentence. However, I kind of slacked off in elementary school and high school English classes so I can't actually explain WHY we use the singular 'discover' when the discovery is made by two people, and we use the plural 'discovers' when the discovery is made by one person.

I really should learn my native language sometime!
