cybergenesis2008 points us to a summary of research out of Harvard Medical School in which a set of genes known to affect aging in yeast was found to affect aging in mice as well. The genes, called sirtuins, perform two particular tasks; regulating which genes are "on" and "off," and also helping to repair damaged DNA. As an organism ages, the frequency of damage to DNA increases, leaving less time for the sirtuins' regulatory tasks. The increasingly unregulated genes then become a significant factor in aging. Realizing this, the researchers "administered extra copies of the sirtuin gene [to the mice], or fed them the sirtuin activator resveratrol, which in turn extended their mean lifespan by 24 to 46 percent." We discussed the plans for this research a few years ago.

The problem seems to be caused by the presence of a Boot Camp partition and renders the Mac unable to reboot after the update fails. Note the Geniuses at the Apple stores are recommending a full disk wipe; but data can be recovered via Firewire." MacNN has a note up that if you fall victim to this "known issue" and need to reformat the disk, you can't reinstall Boot Camp because it is no longer available to OS X 10.4 Tiger users.
