The U.K. might have particular interest in driving this research forward. Foot-and-mouth disease infects cows, pigs and sheep, giving the animals fevers and blisters and reducing the amount of milk they give. Their meat and milk are still technically safe to consume and the disease doesn't affect humans, but it can still hit farmers hard. In 2001, a foot-and-mouth outbreak in the U.K. cost farmers 8 billion British pounds (about $12 billion). North American has been free of foot-and-mouth disease for decades, but it's still rampant around the globe.
