A new analysis of Africa’s past and future climate shows that the Sahel region, which experienced catastrophic drought until rains returned in the 1990s, could experience wetter monsoons for decades to come. However, drought across southern Africa is projected to intensify further. Oceanic warming consistent with an increase in greenhouse gases appears to be a factor in these expected 21st-century changes to Africa’s monsoons.

This may have hi-tech applications, report UCSB scientists

The simple marine sponge is inspiring cutting-edge research in the design of new materials at the University of California, Santa Barbara.

A report about these exciting new results involving the use of gold nanoparticles is the cover story of the current issue of the scientific journal, Advanced Materials. The article is written by Daniel E. Morse, professor of molecular, cellular and developmental biology at U

Ocean-going acoustic sensor array to aid in national security, ocean research efforts

Jason Holmes, a mechanical engineering graduate student at Boston University and guest researcher at Woods Hole Oceanographic Institute, has devised a low-cost, highly sensitive array of underwater ears that is perking up interest in both homeland security and ocean research circles. Holmes’ device — an underwater hydrophone array designed to be towed by a small, autonomous submarine — c

The great Sumatra-Andaman earthquake of December 26, 2004, was an event of stunning proportions, both in its human dimensions–nearly 300,000 lives lost–and as a geological phenomenon. The sudden rupture of a huge fault beneath the Indian Ocean unleashed a devastating tsunami. It was the largest earthquake in the past 40 years and was followed by the second largest just three months later (March 28, 2005) on an adjacent fault.

Modern monitoring technology gathered an unprece

The December earthquake and tsunami that killed approximately 300,000 people in the Indian Ocean region was so powerful that no point on Earth went undisturbed, pointing to the need for more active warnings about the consequences of future events, according to University of Colorado at Boulder seismologist Roger Bilham.

Bilham offers his perspective in “A Flying Start, Then a Slow Slip,” an overview of findings on the Sumatra-Andaman earthquake published in the May 20 issue of Scie

Quake was twice as strong, but much slower than thought

The Sumatra-Andaman earthquake that generated a deadly tsunami on Dec. 26 was stronger and slower than most seismologists thought, according to scientists at the University of California, Berkeley, the Wadia Institute of Himalayan Geology in India and the United States Geological Survey (U.S.G.S.).

Using data from global positioning system (GPS) stations around the Pacific and Indian oceans, including previously unav
