Submission + - Cancer resembles life 1 billion years ago (lifescientist.com.au) 4

An anonymous reader writes: What is cancer? It's not an invader, it's spawned from our own bodies. And it bears striking resemblance to early multicellular life from 1 billion years ago. This has led astrobiologists and cosmologists Paul Davies and Charlie Lineweaver to suggest that cancer is driven by primitive genes that govern cellular cooperation, and which kick in when our more recently evolved genes that keep them in check break down. So, far from being rogue cells that mutate out of control, cancers are actually cells that revert to a more ancient level of programming, like booting in Safe Mode. The good news is this means cancers have only finite variation. Once we nut out the ancient genes, we'll know how it works, and it's unlike to evolve any new defence mechanisms, meaning curing cancer might be not quite as mammoth a task as commonly thought.

Only 2 percent list their cell phone numbers.' The study comes among growing think-of-the-children brouhaha in state legislatures about the dangers of online predators. From the article: 'According to Pew, 45 percent of online teens do not have profiles at all, a figure that contradicts widespread perceptions that the nation's youths are continually on MySpace.'

Journal Journal: OpenBSD's second remote hole in the default installation

The OpenBSD project has just issued an advisory (and updated its website to reflect the change) that it now has its second remote root vulnerability in more than ten years. The exploit itself is performed with a specially crafted IPv6 ICMP packet, and is caused by a bug in the mbuf chains in the operating system kernel. The OpenBSD team have released a patch. The bug affects all versions of OpenBSD. Since
