The BBC has a short article on the first DNA isolated from a Neanderthal's nucleus. (Previous efforts have gotten DNA from their mitochondria, which are small energy-generating organelles.) The results, announced at a meeting, are the fruits of a new method for extracting genetic information from fossils. Theoretically it should be possible to pull together a lot of pieces of Neanderthal DNA into something approaching a genome. We'll have to wait for the big paper for the details, but these early clues suggest it will be worth the wait.
Update: More from John Hawks here.

A lot of people think of viruses and bacteria in our bodies as nothing more than pests. It's certainly true that a lot of them do an excellent job of making us ill. But some viruses and bacteria merged with our ancestors over the course of billions of years, and if you were to have them removed…

These biologists are holding out on me.
I've been writing about biology for quite some time now, and sometimes I think I've got a pretty good sense of the scope of life. Neurosurgeon wasps--got it. Eels with alien jaws--check. And then I stumble across something new, or should I say, new to me.…
That's great, maybe then we will know for sure if the Neanderthal were absorbed by the homo sapiens or not.
