Some spikes in malaria cases may be tied to amphibian die-offs
Amphibian deaths from a fungal disease may have led to more mosquitoes — and an increase in malaria cases in Costa Rica and Panama.

Scientists Say: Atmosphere
An atmosphere is an envelope of gas around a planet, dwarf planet or moon.

Night lights make even the seas bright
Light from coastal cities and offshore development may shine deep enough to disrupt tiny critters living dozens of meters (yards) below the surface.
