Honey bees are disappearing. The story has been in the news on and off since 2006, but for one reason or another, most people have paid little attention. And the situation is significantly dire.

Researchers plan to use satellites to predict the movements of an unusual culprit in China. Their target: a dangerous underwater snail.

Underwater snails don’t sound very menacing. But some snails carry a kind of flatworm parasite called schistosoma. The parasite causes schistosomiasis, the second most widespread tropical disease after malaria. In China’s largest freshwater lake, Poyang Lake, there are billions of these snails, each one no bigger than the tip of your pinky finger.

“There are huge signs there that tell people not to go into the lake. People know about the dangers of infection, but they have to touch the water to some extent. It’s part of their lifestyle,” said Motomu Ibaraki, the US-based leader of the research project.

With the help of satellites, scientists will be able to track which areas have water conditions favorable to the snails. By keeping tabs on the probable whereabouts of the disease-carrying snails, health officials can ramp up the battle against schistosomiasis, sometimes also called “snail fever”.
