Radiation Dosage Chart. Western Philosophy. The Galileo Project. Stephen Hawking: "Why Isn't the Milky Way Crawling With Mechanical or Biological Life?" (A New Year's Weekend Classic) Why hasn't the Earth been visited, and even colonized? Hawking asks. "I discount suggestions that UFO's contain beings from outer space. I think any visits by aliens, would be much more obvious, and probably also, much more unpleasant.
" Hawking continues: "What is the explanation of why we have not been visited? One possibility is that the argument, about the appearance of life on Earth, is wrong. Maybe the probability of life spontaneously appearing is so low, that Earth is the only planet in the galaxy, or in the observable universe, in which it happened. Another possibility is that there was a reasonable probability of forming self reproducing systems, like cells, but that most of these forms of life did not evolve intelligence. " We are used to thinking of intelligent life, as an inevitable consequence of evolution, Hawking emphasized, but it is more likely that evolution is a random process, with intelligence as only one of a large number of possible outcomes.

Scientists Now Know: We're Not From Here! Summary & comments by Dan Eden for Viewzone Imagine the shock of growing up in a loving family with people you call "Mum" and "Dad" and then, suddenly, learning that you are actually adopted! This same sense of shock came as scientists announced that the Sun, the Moon, our planet and its siblings, were not born into the familiar band of stars known as the Milky Way galaxy, but we actually belong to a strange formation with the unfamiliar name of the Sagittarius Dwarf galaxy!
How can this be? Using volumes of data from the Two-Micron All Sky Survey (2MASS), a major project to survey the sky in infrared light led by the University of Massachusetts, the astronomers are answering questions that have baffled scientists for decades and proving that our own Milky Way is consuming one of its neighbors in a dramatic display of ongoing galactic cannibalism. A new infra red digital survey of the entire sky was made in 2003. Not any more.

In the age of internet, television, and Lady Gaga, it’s easy to ignore the dazzling displays the sky gives us every night. In ancient times, however, human civilizations based their entire calendar, and thus their way of life, upon what they saw in the cosmos.
While humanity’s interest in astronomy has diminished over the centuries, the sky remains nonetheless spectacular. Few people have the time to go stargazing every night, but here are 5 celestial events so awe-inspiring, everyone must see them in their lifetime. 5. Perseid Meteor Shower Next Occurrence: August 9-14, 2011 Every August, the night sky lights up with a dazzling display known as the Perseid meteor shower. 4. Next Occurrence: June 15, 2011 in Africa Ever get bored with the predictably drab hue of the moon? 3. Occurrence: Year round More commonly known as the Northern Lights, Aurora is a fantastic light display that occurs at extreme Northern or Southern latitudes. 2. 1.

How to increase serotonin in the human brain without drugs. Radiation No Concern for Space Crops? Radioactivity lingering in the soil near the site of the Chernobyl nuclear power plant accident has not prevented life from creeping back at the Ukrainian site. Now researchers have discovered that oil-rich flax plants grown in the highly radioactive soil can apparently adapt and thrive with few problems.
The first generation survived with changes in barely 5 percent of the plant proteins, and researchers have also collected results from a second generation of flax grown in a radioactive plot of land near Chernobyl. But a mystery remains as to how the flax – a source of plant fiber and dietary oil – has adapted biochemically to the highly radioactive environment. Either way, researchers have been surprised to see that "the radioactive Chernobyl area is not a desert, but is full of life," according to Martin Hajduch, senior scientist at the Slovak Academy of Sciences' Institute of Plant Genetics and Biotechnology. Times are changing The next generation Going green in space. The Brain—Information about the Brain. 1 Introduction “I think, therefore I am.” —René Descartes, 17th-century philosopher Few of us question the crucial importance of the brain.
It is vital to our existence. Our brains enable us to think, as René Descartes so skillfully pointed out nearly 400 years ago. Yet the human brain is responsible for so much more. The brain makes up only 2 percent of our body weight, but it consumes 20 percent of the oxygen we breathe and 20 percent of the energy we consume. Scientists have worked for many years to unravel the complex workings of the brain. Despite these and other significant advances in the field of brain research, most of the processes responsible for the integrated functioning of billions of brain cells remain a mystery.
An essential aspect of any scientific research is communicating results to the public in a way that is easily understood. 2 Myths and Realities about the Brain Myth: The brain is separate from the nervous system. Myth: The brain is a uniform mass of tissue. 4.2 Glia.
