Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:g STARS - For the first time, researchers at Rice University have succeeded in creating and observing an elusive and long-sought quantum state - a superfluid of fermions with mismatched numbers of dance partners. The experiments offer physicists a new window into two of the least understood and most intriguing phenomena in physics - superconductivity and superfluidity. See article.g ABODES - Auroras similar to Earth's Northern Lights appear to be common on Mars, according to physicists at the University of California, Berkeley, who have analyzed six years' worth of data from the Mars Global Surveyor. See article.g LIFE - By comparing foxes selected for tameness with others that have not been selected in this way, researchers have found evidence that dramatic behavioral and physiological changes accompanying tameness may be associated with only limited changes in gene activity in the brain. See article.g INTELLIGENCE - Researchers have discovered the first brain regulatory gene that shows clear evidence of evolution from lower primates to humans. They said the evolution of humans might well have depended in part on hyperactivation of the gene, called prodynorphin, that plays critical roles in regulating perception, behavior and memory. See article.g MESSAGE - Most people see SETI as a project for merely listening for signals from other stars, but Yvan Dutil and Stephane Dumas from the Defence Research Establishment Valcartier in Canada had other ideas in mind when they composed a message sent to the stars in 1999. See article. Note: This article is from 2000.g COSMICUS - On Sept. 19 NASA Administrator Mike Griffin revealed the agency's new plan for implementing the president's Vision for Space Exploration. The plan has significant positive and negative features. See article.g LEARNING - Here's a neat classroom activity: "The Drake Equation". Students examine the range and definition of each variable comprising the Drake Equation and evaluate how changes in the variables influence their result.g IMAGINING - The alien invasion is a common theme in science fiction stories and film, in which a technologically-superior extraterrestrial society invades Earth with the intent to replace human life, or to enslave it under a colonial system. But would aliens actually ever attack another planet? See article.g AFTERMATH - Book alert: The authentic discovery of extraterrestrial life would usher in a scientific revolution on par with Copernicus or Darwin, writes Paul Davies in "Are We Alone?: Philosophical Implications of the Discovery of Extraterrestrial Life". Just as these ideas sparked religious and philosophical controversy when they were first offered, so would proof of life arising away from Earth. With this brief book (160 pages, including two appendices and an index), Davies tries to get ahead of the curve and begin to sort out the metaphysical mess before it happens. Many science fiction writers have preceded him, of course, but here the matter is plainly put. This is a very good introduction to a compelling subject.Read this blogger's books
