Earth

World's Oldest Rocks Found 254

Posted by timothy

Smivs writes "The BBC reports that Earth's most ancient rocks, with an age of 4.28 billion years, have been found on the shore of Hudson Bay, Canada. Writing in Science journal, a team reports finding that a sample of Nuvvuagittuq greenstone is 250 million years older than any rocks known. It may even hold evidence of activity by ancient life forms. If so, it would be the earliest evidence of life on Earth — but co-author Don Francis cautioned that this had not been established. 'The rocks contain a very special chemical signature — one that can only be found in rocks which are very, very old,' he said."

To the original poster of this article:

They're not trying to patent the use of tags. They're trying to patent a metric for measuring and quantifying meta tags.

The weird thing about this is that their metric doesn't actually measure the media itself, only the quantity of meta tags. I guess it works as a metric, but it's more a measurement of popularity, not "interestingness".
