An international team of scientists has presented its findings from the first observations of the eruption of a submarine volcano that in 2004 and 2005 spewed out plumes of sulfur-rich fluid and pulses of volcanic ash 550 meters below the ocean’s surface near the Mariana Islands northwest of Guam.

Those findings will be published Thursday in Nature – just after many of those same scientists returned from another expedition to the site, where they observed new bursts of erupting

Kelp forest ecosystems that span the West Coast –– from Alaska to Mexico’s Baja Peninsula –– are at greater risk from overfishing than from the effects of run-off from fertilizers or sewage on the shore, say scientists at the University of California, Santa Barbara. The findings have important implications for the design of California’s Marine Protected Areas.

In an article published in the May 26 issue of Science, scientists describe the first study to compare the top-down ver

When most people think of Louisiana as being unique, they think of Mardi Gras, crawfish and Cajun culture. Few realize that what lies beneath the Gulf of Mexico along Louisiana’s coast is also unique, from the terrain and habitat to the animals living there. And two LSU researchers are diving down some 3,000 meters to explore it.

Researchers Harry Roberts and Bob Carney are combing the most unique continenta

Scientists don’t know if global warming is responsible

Atmospheric temperature measurements by U.S. weather satellites indicate Earth’s hot, tropical zone has expanded farther from the equator since 1979, says a study by scientists from the University of Utah and University of Washington.
Researchers say the apparent north-south widening of the tropics amounts to 2 degrees of latitude or 140 miles. But they do not know yet if the tropical expansion was triggered by

Scientists at Duke and Rutgers universities have developed a mathematical framework they say will enable astronomers to test a new five-dimensional theory of gravity that competes with Einstein’s General Theory of Relativity.

Charles R. Keeton of Rutgers and Arlie O. Petters of Duke base their work on a recent theory called the type II Randall-Sundrum braneworld gravity model. The theory holds that the visible universe is a membrane (hence “braneworld”) embedded within a l

Mystery is surrounding the huge declines of birds that migrate thousands of miles from Africa to the UK and Europe each spring.

Scientists fear that their dwindling numbers – well over 50 per cent down in some cases – may be a warning of widespread environmental damage, which could soon affect man as well.

Climate change, drought and desertification in Africa, and massive pesticide use on African farmland may all be to blame for the declines of once common UK birds such
