Imagine being an astronomer in a world where the telescope was banned. This effectively happened in the 1600s when, for over 100 years, the Catholic Church prohibited access to knowledge of the heavens in a vain attempt to stop scientists proving that the earth was not the center of the universe.  ‘Surely similar censorship could [...]

EPA dispersant tests show limited toxicity but questions remain

The U.S. Environmental Protection Agency released preliminary data Wednesday from its own toxicity testing for eight dispersants in a bid to corroborate potentially suspect industry-provided results.
