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."

If you like building in SL but hate the tedium, you should check out Skidz Primz. It builds a intuitive UI around regular prims. Especially useful when trying to put many prims together.

(Skidz is a friend and I couldn't resist pimping his tools. Dont hold this spam against him please)

Dead? No excuse for laying off work.
