The world’s oceans hold the key to our future electricity needs. And their potential for producing power has yet to be fully exploited in terms of sustainable energy. The EUREKA WWEC project team hopes to bring exploitation of this renewable energy source a big step forward.

“We’ve developed a device that generates energy from the sea as easily as a wind turbine would do on land,” explains William Dick, managing director of the Irish company Wavebob that led the project. “There’s an awful lo

Dust from China’s Takla-Makan desert traveled more than 20,000 kilometers [12,000 miles] in about two weeks, crossing the Pacific Ocean, North America, and the Atlantic Ocean, before settling atop the French Alps. Chinese dust plumes had been known to reach North America and even Greenland, but had never before been reported in Europe.

An international team of scientists, using atmospheric computer models, studied dust that traveled the globe from February 25 to March 7, 1990. Their findin

90 % of all large fish including tuna, marlin, swordfish, sharks, cod and halibut are gone – leading scientists say need to attempt restoration on a global scale is urgent

The cover story of the May 15th issue of the international journal Nature reveals that we have only 10% of all large fish– both open ocean species including tuna, swordfish, marlin and the large groundfish such as cod, halibut, skates and flounder– left in the sea. Most strikingly, the study shows that industrial

New list spotlights most endangered turtles and action plan to save them

The Turtle Conservation Fund (TCF) today released its first-ever list of the World’s Top 25 Most Endangered Turtles to highlight the survival crisis facing the world’s tortoises and freshwater turtles and to unveil a Global Action Plan to prevent further extinctions. Fully 200 of the 300 living species of tortoises and freshwater turtles are threatened and require conservation action.

We humans are poorly adapted for underwater vision. However, the Moken peoples of south-east Asia manage to collect shells, clams and sea cucumbers using no visual aids when diving to a depth of 3 or 4 metres. Scientists from Lund University in Sweden have now measured the visual acuity of these children and have found that their ability to see well underwater is not a myth: their acuity in this environment is indeed superior to that of European children. The scientists have also found an explanation

Your local weather forecaster uses Doppler radar systems, covering U.S. regions, to estimate rainfall and flooding, but NASA research satellites can see rainfall worldwide.

Data from NASA’s Tropical Rainfall Measuring Mission (TRMM)satellite, along with information from other satellites, allows researchers to see how much rain is falling over most of the world every three hours. This capability enables scientists to daily map areas of potential flooding.
