TeaCurran writes with this mildly ranty objection to the most recent Mac OS X update; several friends who have made the leap on their MacBook Pros have various other complaints, too, including system slowdowns that resemble crashes (except that their pointers still work) and recurring black screens for some configurations (with or without the kernel panics TeaCurran mentions) — what's been your experience? "Apple OS X Lion shipped with new NVidia video drivers that are causing anyone with a mid 2010 Macbook Pro to get a kernel panic every 5-10 minutes. Apple knew about the issue before shipping lion, hasn't responded to the issue, and is censoring posts in their support forum that mention words like 'boycott' and 'petition.' NVidia has responded that the drivers are the responsibility of Apple so they won't deal with the issue. How a major hardware manufacturer can ship such a faulty product without getting much press about it is completely beyond me."

An anonymous reader writes "A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth's core, 1,800 miles underground. The magnetic field strength is 25 Gauss, or 50 times stronger than the magnetic field at the surface that makes compass needles align north-south. Though this number is in the middle of the range geophysicists predict, it puts constraints on the identity of the heat sources in the core that keep the internal dynamo running to maintain this magnetic field."
