The Galileo Project The Galileo Project is a source of information on the life and work of Galileo Galilei (1564-1642). Our aim is to provide hypertextual information about Galileo and the science of his time to viewers of all ages and levels of expertise. What you read and see here is a beginning -- we will continue to add and update information as it becomes available. We solicit contributions from our colleagues in the history of science and comments on how we can improve the project from everyone, particularly suggestions on how to make this tool more useful in primary and secondary education. This project is currently supported by the Office of the Vice President of Computing of Rice University.
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. Stephen Hawking: "Why Isn't the Milky Way Crawling With Mechanical or Biological Life?"

is a sandbox construction game, inspired by Infiniminer, Dwarf Fortress and Dungeon Keeper, created by Markus Persson, the founder of Mojang AB. The game involves players placing and breaking various types of blocks in a three-dimensional environment. The player takes on an avatar that can break and place blocks, forming fantastic structures, creations, and artwork, on multiplayer servers and singleplayer worlds across multiple game modes. Minecraft is available to all players for €19.95 (US$26.95, £17.95).
Scientists Now Know: We're From Sagittarius Dwarf Galaxy! 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.
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.

For the last 4 decades, the question of how to manipulate the serotonergic system with drugs has been an important area of research in biological psychiatry, and this research has led to advances in the treatment of depression. Research on the association between various polymorphisms and depression supports the idea that serotonin plays a role, not only in the treatment of depression but also in susceptibility to depression and suicide. The research focus here has been on polymorphisms of the serotonin transporter, but other serotonin-related genes may also be involved.1–5 In the future, genetic research will make it possible to predict with increasing accuracy who is susceptible to depression. Much less attention has been given to how this information will be used for the benefit of individuals with a serotonin-related susceptibility to depression, and little evidence exists concerning strategies to prevent depression in those with such a susceptibility.
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.
