Washington, Oct 22 : A team of cosmologists from the University of the Basque Country has determined that the accelerated expansion of the Universe can be explained by dark ‘phantom’ energy.

To explain the majority of the phenomena occurring in the Universe, complicated calculations with a computer are required and which have to be based on appropriate mathematical models.

This is what the Gravitation and Cosmology research team at the University of the Basque Country (UPV/EHU) is involved in: analyzing models capable of explaining the evolution of the Universe.

One of the phenomena that standard models of physics have not yet been able to explain is that of the accelerated expansion of the Universe.

Washington, Oct 22 : College students who do not take proper sleep, excessively sit before television or computer screens, suffer from stress, gamble, use alcohol or tobacco, or suffer from other health-related issues do not fare well in academics, according to a new study.

Researchers at the University of Minnesota Boynton Health Service claim that their study is the first to show a direct link between health-related behaviours and grades.

In a surprise appearance on “The Ellen DeGeneres Show”, Barack Obama showed Degeneres his dance moves, while taping it all on Tuesday in Miami, in front of a live audience. Right after the rally, with nearly 40 people behind him, Obama was ready to go via satellite.

The ‘ball’ set rolling when DeGeneres got right down to business, commenting on Obama’s dancing prowess, or lack of it, saying: “Your wife, Michelle, was on the show and she was talking some smack about your moves.”

Washington, Oct 22 : Astronomers from the University of Florida (UF) and University of California-Santa Cruz have discovered the onset of a huge flow of gas from a quasar, or the super-bright core of an extremely remote young galaxy still being formed.

The gas was expelled from the quasar and its enormous black hole sometime in the space of four years around 10 billion years ago – an extremely brief and ancient blip noticed by the unlikely convergence of two separate observational efforts.

“It was completely serendipitous,” said Fred Hamann, a UF astronomy professor. “In fact, the only way it could have happened is through serendipity,” he added.

Washington, Oct. 22: A new study from North Carolina State University shows that there are definite limits on the government's use of the "war on terror" as a rhetorical tool for advancing federal land-use projects and other policy objectives.

"The government can no longer rely solely on the ''war on terrorism'' and ''national security'' as arguments to maintain a crisis situation where local people willingly sacrifice protection of their ''homeland''," claims the study’s author, Dr. Kenneth S. Zagacki.
