Earlier this week, members of the Hubble Space Telescope (HST) research team announced a new estimate for the universe's age, in one of the team's greatest achievements since the telescope's launch nine years...
Their estimate of 12 billion years for the universe's age is much more accurate than previous estimates, given at somewhere between 10 and 20 billion years...
...relation between an object's distance and the speed at which it is receding is represented by what astronomers call the Hubble constant. Discovery of the constant would lead to an estimate of the age of the universe...
George Lucas has said on many occasions that he made "The Phantom Menace," along with the other "Star Wars" films, primarily for kids. What has left unsaid is that children do not have to be limited by age: the movie is for the childlike joy and wonder left in all of us, if only we look for it within ourselves. It is so easy to abandon these things as the detritus of a journey to "maturity"; however, being older and "wiser" does not mean that we're any closer to the truth. When we are children, we often...
Research published in Thursday's issue of the journal Nature suggests that the cloned ewe named Dolly could be -- as an observer once joked -- a sheep in lamb's clothing. The three-year-old Finn Dorset ewe, it turns out, may be susceptible to premature aging. Researchers have determined that chromosome tips, known as telomeres, which regulate the lifespan of cells by preventing their genetic code from fraying, are shorter than expected in Dolly. Researchers are not sure whether the "older DNA" is the result of the age of the animal from which Dolly was cloned or the result...
