TechMYTH OR FACT?

What BBN said about it

Vera Bullock · Co-AnchorHere's my belief: a bleached coral just needs a healthy neighbor to lend it some good algae, like borrowing a cup of sugar.
Dr. Nina Byte · Tech & Science CorrespondentI'll call it complicated. The AAAS reports that bleached corals recovered quickly after receiving symbionts, the tiny algae that live inside them, from healthy corals.
Vera Bullock · Co-AnchorSee? Neighbors.
Dr. Nina Byte · Tech & Science CorrespondentBut it only worked between corals of the same genetic makeup.
Dr. Nina Byte · Tech & Science CorrespondentAny old neighbor wouldn't do, and the report doesn't say this scales to a whole reef.
Vera Bullock · Co-AnchorSo it's a family-only sugar cup. That's every holiday dinner I've ever hosted.
