Washington, Nov 13 : The Obamas have many design choices to make when they move into the White House in January 2009. The president-elect and future first lady will supervise the refurbishing and redecorating of the White House residence -- working closely with a team of interior designers.

To have a bowling alley or a basketball court, traditional presidential porcelain or contemporary American china, a painting of the American frontier or one that captures Chicago’s skyline are are some of the choices Barack and Michelle Obama will make as they transform the 208-year-old White House into the place they call home.

Washington, Nov 13 : Researchers at the University of British Columbia (UBC) have found a way to accurately predict the impact of climate change on endangered Pacific salmon stocks that could result in better management strategies.

The findings are among the first to quantify a relationship between river temperature and salmon mortality rate.

While climate change and rising river temperatures have been linked to dwindling salmon stocks, other factors have made it difficult to measure the exact impact.

Those factors include diseases, fisheries and man-made structures such as dams and fish ladders.

Washington, Nov 13 : NASA’s first spacecraft dedicated to studying carbon dioxide, has arrived at its launch site at Vandenberg Air Force Base, California, to begin final launch preparations.

Washington, Nov 13: A new study has suggested that generating wind power at sea may alter ocean currents and marine ecosystems, bringing nutrient-rich waters up from the depths, which marine life can thrive on.

Extracting energy from wind changes regional air currents, which can in turn affect how the nearby ocean circulates, Goran Brostrom of the Norwegian Meteorological Institute in Oslo, told Discovery News.

Brostrom has shown in a model that winds swirling at five to 10 meters per second (11 to 22 miles per hour) downwind of large farms are uneven.

As they blow over the ocean they can roil the waters, causing upwelling.
