Toxic Surfs
Scientists have discovered not only three new mechanisms by which an alga species in Florida water can poison but also a trio of natural antidotes produced within that same species.

Letters from the July 16, 2005, issue of Science News
Muddy, clarified “Muddy Waters” (SN: 5/21/05, p. 328), on the deleterious effect of dams on coastal systems, contains a major conceptual error. It states that “another important cause of the ground sinking is the waning of sediment deposition by the Mississippi River.” But over the past 100 million years, the northern Gulf Coast region has […]

Growth Slumps: Melting permafrost shapes Alaskan lakes
A new model suggests that some fast-growing, egg-shaped lakes in Alaska expand when their permafrost banks melt and slump in tiny landslides.

Volcanic Hot Spots
Many geophysical studies, including analyses of deep-traveling seismic waves and computer simulations of flowing molten rock deep beneath Earth's crust, are providing evidence that mantle plumes actually exist.

Wetland Blanket: Volcanic sulfates may curb methane emission
Field studies hint that the deposition on wetlands of sulfate compounds from the atmosphere could temporarily stifle those regions' natural emissions of methane.
