Using NASA's Hubble Space Telescope, researchers have discovered that dark energy, a mysterious repulsive force that makes the universe expand at an ever-faster rate, is not new but rather has been present in the universe for most of its 13-billion-year history.Dark energy was already accelerating the expansion of the universe at least as long as 9 billion years ago. This picture of dark energy would be consistent with Albert Einstein's prediction, nearly a century ago, that a repulsive form of gravity emanates from empty space.

5- to 7-year-olds more attracted to lucky individuals and groups than victims of bad luck.Children as young as five to seven years of age prefer lucky individuals over the less fortunate. This phenomenon, the researchers say, could clarify the origins of human attitudes toward differing social groups and help explain the persistence of social inequality.
lack and generalize this preference to those who share membership in a group. Because the disadvantaged are more likely to experience negative events beyond their control -- such as the tendency for the poor to be most impacted by natural disasters -- this innocuous preference for the privileged may eventually grow more harmful, further increasing negativity toward the disadvantaged.

that portrayal cannot be accurate, Efthimiou says. For ghosts to have the ability to walk like humans, they would need to put a force upon the floor, which would exert an equal and opposite force in return.
John Peel left his coveted collection of more than 25,000 records to his wife in his will, it emerged last night. Sheila Ravenscroft will also receive the legendary Radio 1 DJ's estate, valued at more than £1.5m.
Ravenscroft was granted the 25,000 vinyl albums and thousands of CDs after Peel, who died in October 2004, failed to specifically assign them in his will. In typically laid-back fashion, he said: "I ask her (but without imposing any binding obligation) to give effect to any wishes of mine which may come to her attention as to their disposal."
Peel's four children were left more than £250,000 in trust to be split between them. Peel enjoyed national acclaim in a career that spanned over 40 years and included Radio 4.
