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."

xPsi writes "Brian May, the guitarist for the legendary rock band Queen (age 60), has finally decided to submit his Ph.D. thesis in astrophysics. The title is 'Radial Velocities in the Zodiacal Dust Cloud.' From the article: 'May was studying astrophysics at Imperial College when he formed Queen with singer Freddie Mercury and drummer Roger Taylor in 1970. He dropped his doctorate research into interstellar dust as the band met with increasing success.' And, hey, if this whole Rock-n-Roll thing doesn't pan out, at least he'll have something to fall back on."
