Over a century and a half ago, Charles Darwin first described the remarkable adhesive capabilities of barnacles. He couldn't figure out how their natural superglue worked, though. And it took until now to finally unlock the barnacle glue's mysteries.
It's a problem as old as sailing itself. Ever since man set out sea, barnacles have been clinging like, well, barnacles to ships, growing into bumpy masses that slows down vessels and wastes fuel. Could the solution to this age-old dilemma be a new coat of special paint? It's not as simple as it sounds.
