May be I was sleeping!

I did not notice that last week's issue of Nature ran a special edition on sleep; some of the articles were also titled neat; Sleep is of the brain, by the brain and for the brain, one of them said, for example.

The same issue of nature also carries an article by Lindsay Greer and Neil Mathur on the need for an unified approach to the study of chalcogenides, which the materials scientists among you might be interested in taking a look at.

Finally, the essay on this acerbic aphorist is an interesting (and light) read.
