Hands-On With the New MacBooks 128

Posted by timothy from the nice-look-see dept.
Paige Philuer writes "Macworld has a hands-on article examining the new MacBook and MacBook Pro — not a quickie look from Tuesday's event, but a lengthy, in-depth look with laptops they actually have in their offices. Some interesting observations: No FireWire on the MacBook; the TrackPad doesn't feel like you're running your finger across a pane of glass, though that's what it is; and switching between graphics cards in the MacBook Pro requires you to log out." Reader Bourbon contributes three links at CNET related to the new models, too: a positive written review (giving a score of 8/10 to the new MacBook), a video review, and a behind-the-scenes look at how the new models are machined.

Submission + - New Theory Explains Periodic Mass Extinctions

Submitted by i_like_spam
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 news, 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 extragalatic cosmic rays causes mass extinctions. Here is the original paper describing the finding.
