The pen has always been a risk. The american (canadian) dream is financial and not ethical or intellectual. People writing dangerous ideas have always been a threat and doing so has been tolerated as far as it doesn't pose and significant threat to making money. The difference now is that the government can now eavesdrop on the pen and they want to do so to better ensure that there aren't too many dangerous ideas.

New Theory Explains Periodic Mass Extinctions 383

i_like_spam writes "The theory that the dinosaurs were wiped out by an asteroid impact, the K-T extinction, is well known and supported by fossil and geological evidence. Asteroid impact theory does not apply to the other fluctuations in biodiversity, however, which follow an approximate 62 million-year cycle. As reported in Science, a new theory seems to explain periodic mass extinctions. The new theory found that oscillations in the Sun relative to the plane of the Milky Way correlate with changes in biodiversity on Earth. The researchers suggest that an increase in the exposure of Earth to extragalactic cosmic rays causes mass extinctions. The original paper describing the findings is available online."
