The fish comes from East Asia and was first discovered in the Ebro delta in 2001. Since then, it has occupied various parts of the river during its lightning spread, and is now definitively established. The researchers do not rule out that it could occupy new areas within coming years and threaten the survival of native species. View the full article

Economists use leading indicators -- the drivers of economic performance -- to take the temperature of the economy and predict the future. Now, in a new study, scientists take a page from the social science handbook and use leading indicators of the environment to presage the potential collapse of ecosystems. View the full article

Its up to you to see if you want wet foam or dry to adjust the water level accordingly. Most people set the water level to the bottom of the neck. Too low and if you neck is too dry, the foam can't 'climb' into the collection cup.
