Most of us are unsuspecting chemical addicts, and one family is helping to educate us. The Goode family are stars of the documentary Chemerical: Redefining Clean for a New Generation. For three months the Goodes were documented as they replaced all their cleaning products with the old-fashioned stuff: baking soda, vinegar, borax, and combinations of […]

Will that be happening in real life? Scientists say it is probable. Eventually. When Apophis, a 270-metre wide asteroid, was first discovered in 2004, astronomers estimated […]
Volcanoes are one of those parts of science that we all find fascinating; from a distance. Perhaps you are old enough, like Grandpa Richard, to remember the Mount St. Helen’s volcano erupting back in the 1980’s. A friend visited the area afterwards and brought me a jar of ash from the site. Unfortunately, I have […]

Interesting post on Slashdot explaining how the Earth’s period of habitability is coming to an end soon. Well, soon on a cosmological timescale. As they say on Stargate, we need to start considering an alpha site we can move some of us to.
